To decorate the walls of a house, a variety of coatings are used, imitating stone and wood, plastic, and metal sheets. But at the same time, starting and finishing facade putty is necessary to use any of these coatings.
Types and their features
Putty is a powder or liquid (diluted) construction material, which performs the function of leveling the surface and giving it aesthetic beauty. It is mainly used to eliminate unevenness and small cracks on the wall.

The material is classified according to type of use (there are mixtures for interior and exterior use), composition and consistency. Let's look at each type.
Powdered façade putties are perfect for any conditions of use, since it is possible to knead the mixture to the desired consistency. This may be necessary when working on complex objects with various problems(wall cracks, uneven surfaces or porous surfaces). They tolerate transportation and storage well in any conditions (except high humidity). Sales are made in markets, in special stores and online portals. But such compositions have some disadvantages. Firstly, it is not always convenient to prepare the mixture yourself, and secondly, the storage time of ready-made putty is limited.
Photo - dry putty Therefore, despite more high cost, now they use façade more often putty in liquid form, which is immediately ready for use. It is sold in bottles or canisters and has a fairly long shelf life. The advantages include saving time on preparatory processes and ease of use. This leveling mixture is made from synthetic materials, which in certain proportions are combined with natural ones. Latex is used as preservatives.
The use of putties also varies. Depending on what properties the coating has, it can be used in street conditions or only for interior work. There is also a base and finishing putty. Their difference lies in the size of the grains and the principle of application. Basic putty applied directly to the prepared wall of the house for further covering with plaster or other building materials. Finish It is also used for final work. Most often, the facade is treated with it before painting. Now there is a combined universal medium-grain putty that can be used both for finishing work and in the initial stages of construction.

Based on their composition, materials are divided into:
- Acrylic;
- Acrylate;
- Cement;
- Plaster;
- Polymer.
Acrylic facade decorative putty(Acrofiller, Poots, Eunice) is very famous due to its characteristics. It is produced immediately in finished form, the liquid has an average viscosity, which greatly simplifies the process of applying the mixture to the wall. It can be used when working on wood, stone, brick and any other surfaces. This putty is latex and moisture resistant.
Latex or acrylate mixture(Alfil, Forward) is known for its improved moisture-resistant characteristics. If frost-resistant acrylic can be used in any conditions, then acrylate is suitable exclusively for application to external walls or ceilings.
Photo - acrylic facade putty with cellulose Application gypsum putty possible in almost any conditions, but you need to carefully read the instructions from the manufacturer. The properties of the material depend on certain polymer additives. For example, a mixture of gypsum and polystyrene foam is perfect for cold regions, and a ready-made mixture with latex is perfect for areas with high humidity.
Facade non-shrinkable gypsum mixture(Bolars, Ceresit - Ceresit) also comes ready-made or in powder, depending on needs and capabilities (liquid is more expensive). But gypsum has a significant drawback - it cannot be used in very humid areas, otherwise it will become moldy. To solve these problems, manufacturers combine natural minerals with synthetic additives.
Photo - façade Bilfa Advantages of gypsum mixtures:
- Excellent technical characteristics;
- Availability;
- The plastic mixture perfectly seals cracks and cracks.
Facade cement putty (Anker, Perfekta, Glims, Bergauf) is used in conditions of high humidity, it best combination price quality. It is very convenient to work on concrete or if you need to repair deep cracks. The main advantage of this composition is that it does not allow moisture to pass into the façade, which has a positive effect on the durability of the building. In most cases, this mixture is produced and sold dry, but it must be stored in dry conditions. Cement putties come in several types:
- Starters;
- Finishers;
- Universal.
Rough starting must be characterized by high ductility and strength, therefore the composition often includes various mineral impurities (particles of lime or marble dust). Compositions with crumbs have a strict grain size limit - up to 0.5 mm. The finish consists of cement, microcalcite and other materials that help ensure maximum evenness of the layer. The disadvantages include high consumption, which is explained by the high absorption of water during preparation of the composition.
Photo - cement Bergauf Polymer superplastic facade putty (Knauf, Ivsil, Weber-Vetonit) is the most modern version this coating. It is used in most cases only on internal works, but if you need to prepare the dock for painting, then its use is necessary. Composition characteristics:
- Resistance to external aggressive influences;
- Smoothness (complete absence of graininess);
- Strength;
- Plastic.
Elastic putty is produced immediately in liquid form with the addition of expanded polystyrene (for example, the Collection brand). Can be used to prepare foam or foam blocks for coating with paint. Often after this, structural decorative bark beetle or roller plaster is applied.

Instructions for use
The final result of the work depends on what type of façade starting or finishing putty is chosen, so it is very important to read the manufacturer’s recommendations.
Photo - use Instructions for use materials and advice from the master:
- The work can easily be done with your own hands, but you need to prepare the wall in advance and necessary tools. To apply any putty (facade, interior), you need prospectors or spatulas. They need to be selected based on your needs, they come in different widths and shapes;
- The moisture-resistant, frost-resistant and relief mixture can be applied to the facade only at above-zero temperatures. Any other use will destroy the structure and it will become cracked due to loss of moisture. Some types of coating can be used for sub-zero temperatures(Rusean, Kreps, VTG) is a winter putty;
- Before starting repairs, you need to take care of the cleanliness of the walls. They are cleaned with brushes with metal bristles and coated with several layers of primer;
- Application technology depends on the type of material. The easiest way is beacon coverage. Here you need to apply several strips to the wall, the thickness of which will indicate the maximum thickness of the coating, and apply further material along them;
- Always carefully read the description from the mixture manufacturer. The instructions indicate not only the composition, but also possible tricks when working with a certain product;
- If after using the mixture you plan to paint the building, then you need to choose a white composition. Gray putty will tint the wall, and the paint will not be as bright.
Before you buy façade putty, you must check the quality certificate. The cost of the material depends on the manufacturer and city of purchase. Eg, cement mixture can cost up to 500 rubles in Voronezh, and up to 700 in Moscow.
Most residential and public buildings under construction are finished plaster mixture, which is called “wet”. Facade putty is a weather-resistant putty for exterior use. Used for final leveling of walls before application decorative covering. It is distinguished by its special strength, moisture resistance, and frost resistance. In this article we will tell you what façade putty should be, how to apply it correctly and choose it.
As mentioned above, facade putties must have certain qualities, namely high frost resistance. A high-quality putty should contain the following components:
- Gypsum or cement.
- Plasticizer.
- Modifying additives.
- Mineral fillers.
Very often, when finishing the facade, putty with a high content of glue, soap, gypsum and chalk is used. Depending on the type of work, different types of this material are selected, the most popular are: combined putty, facade cement, latex mixture, facade acrylic and others. A universal option is considered to be a combined facade putty, which is excellent for leveling the surface; in addition, it allows you to cover even very large defects and defects. The combined putty, even after many years, will not crumble and will not flake even in the cold season.
The shelf life of façade putties is limited to six months. Don't stock up on it in advance!
The most popular types of facade putties
To choose the right putty, you need to learn more about its composition and properties.
Latex putty is not suitable for facades
It is one of the most popular in its segment, suitable for any surfaces in the interior, but not suitable for facades. This material is sold in 25 kilogram buckets. We will mention it only so that you know and do not get confused in choosing.
Adhesive putty
- Possibility to mix with pigment compositions to change color. This will make it possible to do without painting the surface, and any mechanical damage on the walls they will not be so noticeable.
- Putty consumption per one square meter. Consumption usually depends on the thickness of the laid layer and the filler. The smaller the thickness, the more economical the material is.
- The putty must be compatible with any.
- The time period for the mixture to harden.
- Plasticity of the material.
How to choose winter façade putty
What are the main properties of winter façade putties - the ability to work with low temperatures and resistance to dry cracking. For winter, you can use both acrylic and cement putties. But on the manufacturer’s packaging there must be a corresponding entry - “winter series”. Of course, such putties will be a little more expensive than usual, because they have added special construction chemicals that improve setting at low temperatures.
Which façade putty is waterproof?
Cement putty is waterproof. It is used not only for facades, but also for screeding floors and finishing bathtubs in the house. Therefore, it does not require additional polymers and hydrophobic substances, such as gypsum.
Gypsum putty is not at all suitable for facades and can only be used in interiors, and not in wet rooms. Of course, marketers and technologists united and found a way to use it in wet rooms, adding those same water repellents to it.
Does façade putty protect against fungus?
Those façade putties that contain antistatic and antiseptic agents protect. It is better, of course, to treat the effect rather than the cause. And prevent the formation of fungus on the facade. Mold on the facade is always the result of dampness, which for some reason appears and for some reason does not dry out. It is better to think in this direction to exclude the causes of fungus.
Important! Remember that each subsequent layer in the wall structure must be more vapor permeable than the previous one. If this principle is violated, problems with fungus cannot be avoided by any antiseptics. They simply won't cope.
Which façade putty is suitable for painting?
Any. Both acrylic and cement, your choice.
Which façade putty is best for use on plaster?
Any facade putty is suitable for working on a plaster facade. It will be easier to apply acrylic, but it is more expensive than cement. Acrylic is more elastic. Cement is more economical. The choice is yours.
What to do next after plastering the façade walls
Paint, plaster, decorate with panels based on insulation, or use the latest technology hinged ventilated facade. Curtain facade– this is cladding with siding, plastic or metal panels, porcelain stoneware, wood or stone panels. In general, after puttingtying the facade, proceed to the design of the exterior.
How to properly putty a façade
Let’s make a reservation right away: there are two ways to putty a facade: manual and machine. The machine is used to work with large volumes to increase the speed of work. For a private home, of course, this is irrelevant. By the time you get used to the machine, the facade will already be finished, and it will take twice as much material as with the manual method.
Therefore, it is advisable to apply the material on our own, using a spatula or grater. Regardless of the method of applying the material, first of all, the base must be prepared: the surface is cleaned of dirt, dust and oil stains, then priming is performed, which is necessary to ensure adhesion of the materials.
The finished putty material is mixed before work. If there are significant defects on the surface, they must first be eliminated by filling the gaps and cracks with putty. After the “patches” are completely dry, a continuous layer of material can be applied. If necessary, apply several layers. To achieve excellent results finished surface It is recommended to sand.
Advice. Do not putty the façade in high humidity or hot weather When the surface gets very hot, this greatly reduces the quality of the finish. Because putty requires certain time to dry.
Consumption of façade putty per 1m2
- Starting and finishing putty.
- Universal putty.
Consumption per 1 m2 of starting and finishing putty
Starting putty is needed to seal cracks and level out small differences. It is impossible to accurately calculate its consumption, since it is necessary to start from the condition of the wall. But to grout a medium crack, you will need a layer of approximately 3-4 mm per square meter. It may not be necessary to cover the entire wall with starting putty, so it makes sense to estimate the area to be putty.
To cover one square meter with a 4 mm layer of starting putty, you will need four kilograms of dry mixture. Usually the dry mixture comes in 20 kg bags.
The consumption of finishing putty per square meter is less than the starting putty. Largely due to preliminary priming of the surface. You can focus on 1 mm.
To cover one square meter with a 1 mm layer of finishing putty, you will need 1.2 kg of dry mixture.
Consumption per 1 m2 of universal putty
The declared consumption of universal putty by manufacturers is lower than the combination of starting and finishing putty separately. Typically, it is 1.5 kg per square meter for a layer of 1 mm. Manufacturers always indicate consumption on the packaging.
How many mm thick layer you need will all depend on the condition of the surface to be coated. Let's focus on the middle layer of 2 mm.
To cover one square meter with a 2 mm layer of universal putty, you will need 3 kg of dry mixture.
It is justified to use universal putty on more or less smooth and crack-free surfaces.
Stages of work execution
It is recommended to finish the façade after the foundation has settled. As a rule, this process lasts about a year. Processing walls requires some effort and effort; you must be fully prepared for the fact that you will have to do at least two layers of mortar to get the desired result.
It will be impossible to get by with just one layer; even a qualified specialist will not be able to cope with such a task. The best temperature for outdoor work is from 9 to 20 °C, permissible humidity air should not exceed 80%.
The process of applying putty occurs as follows:
- The surface is cleaned of excess dirt and old finishes.
- A primer is placed on the cleaned surface; it must dry before further operation. It is better to prime the surface in two layers.
- Next, depressions, dents, and cracks are removed. After which the material is allowed to dry.
- The putty is applied evenly to the walls and then carefully leveled. It is better to use two metal spatulas as improvised means. different sizes and a construction float. It is important to note that facade material It must be used in its pure form and must not be mixed with paint or other additives.
- After the first layer of putty has dried, it must be primed in order to improve adhesion to other layers.
- The starting putty is applied layer by layer until the surface of the facade is completely straightened. Each layer is applied only after the previous one has dried.
- On last stage finishing putty is laid on top of the base material.
Expert Experience
According to many construction companies, the best putty option for building facades is one that contains cement. This material is quite easy to apply to the surface of the walls and has high strength after drying. If you are going to repair the facade, then you need to understand that each subsequent layer must be more vapor-tight than the previous one. Otherwise, fungus and mold cannot be avoided. So that you don’t have to worry too much about selecting each layer, choose all the elements from the same manufacturer. This guarantees you compliance with the principle of vapor permeability when finishing the facade. This way you can completely protect yourself from incompatibility of materials.
Happy finishing! Share your comments and experiences with façade putty.
A competent choice of putty for the facade allows you to protect yourself from numerous problems in the future. This building material helps prepare the surface for finishing and protects it from negative influences. external influences. It helps smooth out cracks and other defects.
Varieties
Depending on the consistency, they are distinguished the following types façade putty:
- Finishers;
- Starters.
The starting material is characterized by a coarse-grained structure. It is suitable for initial finishing. This putty has good adhesion and is easy to process.
It effectively levels the surface. It is enough to apply layers up to 2 centimeters thick.
Facade finishing putty is very fine. Its use allows you to obtain a smooth and even base. It precedes the start of decorative finishing. Compared to “start”, this material is less durable. When working, you need to ensure that the thickness of the putty applied does not exceed 5 millimeters.
Nowadays there are also universal ones on sale. From the photo of façade putty it cannot be distinguished from other types. They combine the qualities of finishing and starting materials.
Often, they are used for internal repair and construction work. They are not suitable for façade finishing.
When performing external work, materials made from cement or polymers are used. It is resistant to negative temperatures and high humidity.
The “start” contains quartz sand, the “finish” contains marble dust and ground sand. To improve performance, various chemicals are added to the material.
Advantages and disadvantages
All types of putties have their advantages and disadvantages. Let's look at them in detail.
Cement putties: resistant to moisture and temperature changes. They are unpretentious in operation and are affordable. The disadvantages are that the material shrinks. There is also a high probability of cracks and other similar defects.
There are two types of polymer putties:
- Latex;
- Acrylic.
The first ones are considered universal. They are suitable for both outdoor and interior decoration. They are odorless and do not emit substances hazardous to human life and health.
The material is plastic. After drying, no cracks appear on the surface. The only drawback is the high cost.
Acrylic material also has a wide range of applications. Acrylic, present in the base of the putty, provides it with moisture resistance and plasticity. The material does not peel off. It is used for finishing and protecting surfaces made of concrete and foam concrete. Maximum thickness layer is from one to three millimeters.
Craftsmen working with this building material should take into account that the surface must first be primed. There are also disadvantages. Firstly, if there are serious defects on the surface, then puttying will have to be done in several stages. Secondly, grinding work must be performed exclusively in a respirator.
Putty for exterior finishing applied in various ways. The hardware method is considered quite effective. For this purpose, a device is used that supplies the solution under high pressure.
However, there are several requirements. The material must be given the desired consistency. In addition, the hardware method does not allow uniform application of the material.
The optimal solution is to apply the solution to the surface with a grater or spatula.
Regardless of which specific option is chosen, the surface must be thoroughly prepared:
- Clean from oil stains, dirt and dust;
- Treat with a primer (it will ensure ideal adhesion of building materials and protect the surface from mold and mildew).
The finished mixture must be thoroughly mixed, and the dry mixture must be diluted with liquid. It is recommended to strictly follow the manufacturer's instructions.
It is advisable to prepare the solution in small portions. This is explained by the fact that its plasticity gradually decreases. The setting period depends on what ingredients are present in the mixture. Often, it ranges from thirty minutes to two to three hours.
Serious defects must be removed. All cracks, holes and potholes are sealed with putty. It is allowed to begin applying a continuous layer when all the “patches” have dried.
If there is a need, the master can apply several more layers. To achieve a smooth and even base, it must be sanded.

Facade putties are building mixtures, specifically designed to create optimal smooth surfaces and subsequent application of the final decorative finishing layer. The terms putty and putty combine one concept and are of German origin, so both designations may appear in different sources. The task of high-quality putty is not only to level the surface, but also to maximize the protection of external walls from negative impact external factors.
Fine-dispersed façade Decoration Materials, depending on the purpose, can be represented by compositions of different sizes and consistencies:
- starting putty, better known as a base or leveling mixture;
- the finishing version of a fine-grained putty with a relatively liquid consistency;
- a decorative version of putty that allows you to create textured decorative elements;
- wood putty used to level and protect wooden surfaces.
Depending on the intensity of exposure to external factors, not only the compositions, but also the technical characteristics of facade putty mixtures can vary. A high-quality putty must be vapor-permeable, moisture-resistant, frost-resistant and sufficiently elastic, which will allow the work to be completed by applying paint, decorative tiles, enamels, mosaics or other finishing materials.
The base and finishing mixture can be waterproof, frost-resistant and heat-resistant:
- mixtures with water-repellent qualities minimize the risk of condensation appearing on the surface, which can occur under the influence of rain and evaporation. This putty is distinguished by its simple and quick application, uniform distribution, and compatibility with other types of finishing materials;
- frost-resistant mixtures are used when sealing cracks or chips, and increase the resistance of the surface to low-temperature conditions;
- heat-resistant compounds combine excellent adhesive properties and have proven themselves when treating surfaces exposed to high temperatures.

Classification by composition
Each putty mixture is characterized by a composition strictly established by production technology, the main component of which allows us to distinguish several varieties with certain advantages and disadvantages.
| View | Application | Advantages | Flaws |
|---|---|---|---|
| Concrete surfaces with deep cracks. Starting, universal and finishing versions are available, differing in additives. | Resistance to temperature changes, affordable price, ease of work. | Shrinkage occurs and cracking of the layer may occur. |
| The liquid version levels and decorates the surface. Apply with a thickness of 0.1-0.3 cm onto a previously properly prepared and primed surface. | Good moisture-resistant material with a high level of strength and elasticity. | Not suitable for quick fix deep cracks, grinding requires the use of a respirator. |
| Pasture different composition has improved moisture resistance and good frost resistance. | Ease of use, high level plasticity and good protective qualities, durability. | Not very affordable price. |
| Mineral version of facade mixture based on liquid glass, produced in a form ready for use. Suitable for working on surfaces consisting of shell rock and cellular concrete. | High vapor permeability, serves as protection against moisture and dust, and has neutral electrostatic characteristics. | A minimal violation of the application technology can cause cracks to appear. |
| A high level of composition density may affect the uniformity of the applied layer, so certain skills are required in finishing works. | A budget option with high protective properties. | Significant mass and high density, inconvenient application on vertical surfaces. |
| The presence of polystyrene in the composition indicates frost resistance, and latex additives improve water-repellent properties. The mixture can be presented in powder and liquid versions. | Durable and plastic material with an affordable price and excellent technical characteristics. | There are practically no downsides when using high-quality material from official manufacturers. |
| Elastic material with high vapor transmission and strength. Apply in a thin and uniform layer. | Plastic and vapor-permeable composition in a variety of colors. | The cost is too high. |
Making your own putty
If there is a need to save cash When purchasing factory mixtures, it makes sense to prepare the putty yourself:
- To level concrete, relatively flat surfaces, it is recommended to prepare a gypsum-chalk mixture by mixing three parts chalk and part gypsum. With uniform mixing, the bulk ingredients should be gradually poured into a 5% solution based on wood glue. Homemade solution, mixed until smooth, hardens quickly and should be used immediately after preparation;
- for leveling wooden facade It is advisable to use an oil mixture, in the production of which a couple of kilograms of drying oil and four kilograms of chalk are mixed, with the addition of a quarter kilogram of drier. The mixture brought to a boil must be cooled to room temperature.
It should be remembered that the consumption of self-prepared putty will be higher than when applying ready-made factory-produced mixtures.
Preparation of working tools
To carry out puttying work, you will need to purchase some tools to make application easier and get the most even, smooth surface:
- a fairly wide brush with soft bristles or a roller, with which the façade surface is primed;
- a construction mixer or electric drill with an attachment for high-quality mixing of the putty mixture;
- Several spatulas of different sizes allow you to process large areas of the facade, as well as corners or hard-to-reach areas.
Construction mixer price
Construction mixer
If paint is to be used as the final finishing of the facade, then the surface must be absolutely flat and smooth, so a well-dried layer of putty will need to be rubbed with a special fine-grained mesh.
Surface preparation
Regardless of the type, the putty must be applied to an absolutely clean, dry and pre-primed surface. It is best to use primer options for putty, which will avoid plastering the surface. Universal primers can be used on any surface, but many experts consider such materials to be ineffective, so they prefer to use special compounds:

Step-by-step instructions for preliminary preparation facade surface for applying the starting putty layer.
Step 1. We remove all external facade decorative elements and antennas that may interfere with the priming process.
Step 2. We fix all loosely fitting elements to the façade surface or remove them completely.
Step 3. Outer surface We remove dust accumulations with a damp or dry brush with medium-hard bristles.
Step 4. We remove heavy dirt and layers of fatty deposits on the surface with a damp cloth. Too much dirt and paint residues can be removed with solvents, after which the surface is washed with clean water.
Step 5. Using a construction roller, carefully apply the prepared primer solution in a thin but uniform layer.
Depending on the composition and weather conditions, the drying process of the primer can take from four hours to a day or more.

Starting layer application technology
Starting mixtures are coarser and coarser. They are used for rough finishing of facades and have good adhesion to concrete, lime, brick and other substrates. Allows you to fill seams, deep cracks and other large defects.
Depending on the initial state of the facade, the working solution can be applied in a layer of several millimeters or centimeters. It is recommended to apply the starting solution thinly, but in several tiers. In this case, it is possible to obtain a higher quality finish.
Step 1. We dilute cement and gypsum putty compositions with clean water in the proportion recommended by the manufacturer. Polymer compositions are already ready for use and just need to be mixed before application.
Step 2. We take a small amount of working solution onto a construction spatula, and then apply it to the surface with a sweeping and fairly wide movement. During the application process, the spatula must be pressed fairly tightly to the surface at a stable angle of inclination.
Step 3. We immediately smear all sagging and unevenness using an empty spatula, and carefully remove excess mixture.
Step 4. After the solution has hardened, we perform thorough grinding, which allows us to get rid of minor defects and makes the surface even and as smooth as possible.
Facades with strong unevenness need to be leveled in several steps.
Quick-hardening compounds self-made or solutions diluted on the basis of dry ready-made mixtures cannot be stored. They are used as quickly as possible.
Features of finishing putty
The composition of the finishing putty mixtures is represented by fine-grained fractions, due to which the processed structure acquires a smooth and durable structure. Coarse-grained putties based on quartz sand or marble chips, designed to create a relief and highly decorative texture of the facade.
IN last years The most popular way of decorating the facade of buildings is the option in which they use putty, subsequently pigmented with high-quality coloring compounds. Quite often this method is combined with facing works natural or artificial material.
Facade putty can be applied not only manually, but also mechanically, using special equipment. The disadvantage of mechanical application is the lack of the most even application.
Main manufacturers
Putties on the domestic construction market can be presented by both foreign and Russian manufacturers. Of particular interest to consumers are products of medium price category with high product characteristics.

German cement-based Knauf exterior putties are characterized by high levels of frost resistance and moisture resistance, so they will become the best option for finishing the external walls of newly erected buildings and restoring old facade surfaces.
Finnish putty compositions "Vetonit" on acrylic base ideal for working with any concrete or wooden bases subject to high humidity levels.
Domestic mixtures “Ceresit”, “Starateli” and “Bolars” are distinguished not only by their affordable price, but also by their good quality, and also allow you to obtain a durable coating.
Prices for popular types of putty
- the surface of the facade must be prepared in advance, cleaned with a brush with metal bristles and thoroughly primed;
- moisture-resistant, frost-resistant and relief putty mixtures can be applied to façade surface only at positive temperatures;
- at negative temperatures winter putty such as “Rusean”, “Kreps” and “VGT” should be used;
- putty technology may vary depending on the type of material, but the simplest and in an accessible way is application along beacons, which will allow you to obtain an optimal layer thickness;
- under each putty layer, a deep-impact primer solution must be applied, which helps to increase adhesion between the base and the applied composition;
- putty mixture for painting the facade should be white, since gray putties can negatively affect the decorative properties of the finish.
It should be noted that in the instructions, all responsible manufacturers always indicate not only the composition of the mixture, but also certain nuances of working with the material. Before purchasing, you must make sure that there is a quality certificate for the products being sold.

What façade putty for exterior use is currently on the market? Let's find out together what types of putty exist, what these or other compounds are used for, and what brands make a quality product. And for the DIYers, I’ll tell you how to putty the facade of a house for painting with your own hands in two ways.
Puttying the facade is one of the main stages of home improvement.
The question of how to putty the facade is far from idle, because facade putty for exterior work can have a different composition, be intended for different types of base and even differ in layers, that is, each layer has its own mixture.
Dividing mixtures according to purpose
Before you ask the price of putty and think about which one to choose so that your budget doesn’t “crack”, decide for what purpose it is needed:
- Starter or basic– these compounds are intended for initial surface leveling and have good adhesion. But you won’t be able to perfectly level a wall, for example, for painting; the mixture has too large a fraction and no matter how much you sand it, you still won’t achieve gloss. The layer thickness here can reach up to 20 mm;
- Finishing lineups- intended for perfect alignment. Such putties should be applied on top of the starting ones, but on flat wall, for example, on plaster, the finish is applied immediately. The layer thickness does not exceed 4 mm, therefore, the putty consumption per 1 m2 for facade plaster is less, but the price of these mixtures is higher;
- Decorative putty– the main purpose of such compositions is original decor facade, but at the same time they do an excellent job of protecting walls from weather troubles. The fraction and method of application may differ, but the thickness of the decorative layer, as a rule, does not exceed 5–7 mm;
- Compositions for finishing wooden houses now they are classified as a separate category, although this is a controversial issue. Here, exclusively vapor-permeable, water-resistant façade putty is used, because there is moisture both in the atmosphere outside and in the wood itself.
Decorative putty on the facade can be very diverse.
There are also so-called universal compositions; they combine the advantages of starting and finishing putties, but for facade works such mixtures are not used, their purpose is internal surfaces.
Dividing mixtures by composition
The components included in the mixture directly determine for which surfaces such a putty is designed.

Acrylate putty.
Pure latex putty is used in interior work; there are acrylate compounds for facades. Acrylate mixtures are immediately ready for use and are considered perhaps the most waterproof. |
| Silicate compounds.
These compounds are mostly used in decorative niche. Focused on cellular concrete and shell rock, although there are models for all types of base. |
|
| Oil-adhesive compositions.
They have increased frost resistance and an affordable price. Often used for finishing wooden houses. |

How to finish the facade yourself in two ways
For facade work, facade putty on plaster and reinforced facade putty are mainly used. The fact is that white finishing putty, which is often used for painting, is expensive and is applied in a thin layer of up to 4 mm, so the wall must first be leveled and strengthened, and then puttyed.
Method No. 1. We work using beacons
This method is most often used for facades with really curved walls. IN in this case there is no point in applying it to curved walls starting putty, because the consumption per 1 m2 will be huge, it is cheaper to plaster the base with a standard cement-sand mortar in a ratio of 1:4.
| Illustrations | Recommendations |
| We set up beacons.
It is better to buy strips for beacons, in this case we took metal profiles, they are cheaper than carbon fiber.
|
|
| We wet it.
We work in the heat in the summer, so the wall needs to be moistened with water. You can do without this in the off-season. |
|
| Priming.
In this case, a special primer is not needed. We simply mixed up a liquid cement-sand mortar and threw it on the wall. |
|
| Examination.
We apply a rule to the beacons and check that the soil layer does not “peek out” beyond the beacons. |
|
Alignment of walls.
|
|
| We remove the beacons.
Since we are going to putty later for painting, we need to pull out the metal beacons:
|
|
| Align.
Now we need to align the small grooves after the rule:
|
|
| Let's mash it.
Now we bring the surface to the ideal:
|
|
| We apply primer.
The instructions require that the wall be treated with primer before filling, but in such cases I simply moisten the fresh wet plaster with water. |
|
Mix the putty.
|
|
| We apply putty.
In small portions, with a narrow spatula, apply the composition to a wide spatula or trowel and apply the putty in a circular motion.
|
|
| We polish.
You can sand with sandpaper, but the sandpaper gets clogged quickly, so I recommend stretching a sanding mesh over the block and working. Once sanding is complete, all you have to do is brush off the dust from the wall, apply primer for painting, and when it dries, paint the house.
The video in this article shows the intricacies of the work clearly. |
Method number 2. We reinforce the walls
This method is suitable for facades with smooth walls, as well as for puttying insulation boards, for example, extruded polystyrene foam.
| Illustrations | Recommendations |
| Base mixture.
As a base mixture I use cement-based facade adhesive. This mixture is frost-resistant and “clings” tightly to the wall. For brick or concrete, you can take “Moment”; it is cheaper; for expanded polystyrene, it is better to buy “Ceresit-CT83”. After mixing, the glue is applied to the wall with a notched trowel, with a tooth of 10–12 mm. We move from bottom to top. |
|
| We put a corner.
The first to install is a plastic corner with a reinforcing mesh. After you lightly press the corner into the solution, check it vertically. |
|
| We attach the mesh.
Now we cut an ordinary fiberglass mesh to the size of the wall and, overlapping the corner mesh, we sink it into the solution so that it holds. |
|
| Primary alignment.
Now we need to immerse our mesh completely in the adhesive mixture. To do this, take a spatula and press the mesh in with sweeping movements. |
|
| Putty.
Now, using the technology described above, we putty the wall. The only difference is that first we apply and lightly sand the starting coarse-grained compound, and then put a white finishing putty on it. |
Conclusion
As you can see, facade putty is applied quite simply, the main thing is to choose the right composition for a specific base. If you have any questions, write in the comments, I will try to help.

Facade putties are construction mixtures specially designed for creating optimally smooth surfaces and subsequent application of the final decorative finishing layer. The terms putty and putty combine one concept and are of German origin, so both designations may appear in different sources. The task of high-quality putty is not only to level the surface, but also to maximize the protection of external walls from the negative effects of external factors.
DIY façade putty
Classification by purpose
Fine-dispersed facade finishing materials, depending on their purpose, can be represented by compositions of different size fractions and consistencies:
- starting putty, better known as a base or leveling mixture;
- the finishing version of a fine-grained putty with a relatively liquid consistency;
- a decorative version of putty that allows you to create textured decorative elements;
- wood putty used to level and protect wooden surfaces.
Depending on the intensity of exposure to external factors, not only the compositions, but also the technical characteristics of facade putty mixtures can vary. A high-quality putty must be vapor-permeable, moisture-resistant, frost-resistant and sufficiently elastic, which will allow the work to be completed by applying paint, decorative tiles, enamels, mosaics or other finishing materials.
Putties differ in composition and characteristics
The base and finishing mixture can be waterproof, frost-resistant and heat-resistant:
- mixtures with water-repellent qualities minimize the risk of condensation appearing on the surface, which can occur under the influence of rain and evaporation. This putty is distinguished by its simple and quick application, uniform distribution, and compatibility with other types of finishing materials;
- frost-resistant mixtures are used when sealing cracks or chips, and increase the resistance of the surface to low-temperature conditions;
- heat-resistant compounds combine excellent adhesive properties and have proven themselves when treating surfaces exposed to high temperatures.
Putties not only hide unevenness, but also perform protective functions for facade

Classification by composition
Each putty mixture is characterized by a composition strictly established by production technology, the main component of which allows us to distinguish several varieties with certain advantages and disadvantages.
|
Cement |
Concrete surfaces with deep cracks. Starting, universal and finishing versions are available, differing in additives. | Resistance to temperature changes, affordable price, ease of work. | Shrinkage occurs and cracking of the layer may occur. |
|
Acrylic |
The liquid version levels and decorates the surface. Apply with a thickness of 0.1-0.3 cm onto a previously properly prepared and primed surface. | Good moisture-resistant material with a high level of strength and elasticity. | Not suitable for quickly repairing deep cracks; grinding requires the use of a respirator. |
|
Latex |
The paste-like composition has improved moisture resistance and good frost resistance. | Ease of use, high level of plasticity and good protective qualities, durability. | Not very affordable price. |
|
Silicate |
A mineral version of a façade mixture based on liquid glass, produced in a ready-to-use form. Suitable for working on surfaces consisting of shell rock and cellular concrete. | High vapor permeability, serves as protection against moisture and dust, and has neutral electrostatic characteristics. | A minimal violation of the application technology can cause cracks to appear. |
|
Oil-adhesive |
A high level of density of the composition may affect the uniformity of the applied layer, so certain skills in finishing work are required. | A budget option with high protective properties. | Significant mass and high density, inconvenient application on vertical surfaces. |
|
Plaster |
The presence of polystyrene in the composition indicates frost resistance, and latex additives improve water-repellent properties. The mixture can be presented in powder and liquid versions. | Durable and plastic material with an affordable price and excellent technical characteristics. | There are practically no downsides when using high-quality material from official manufacturers. |
|
Silicone |
Elastic material with high vapor transmission and strength. Apply in a thin and uniform layer. | Plastic and vapor-permeable composition in a variety of colors. | The cost is too high. |

Making your own putty
If there is a need to save money on purchasing factory mixtures, it makes sense to prepare the putty yourself:
- To level concrete, relatively flat surfaces, it is recommended to prepare a gypsum-chalk mixture by mixing three parts chalk and part gypsum. With uniform mixing, the bulk ingredients should be gradually poured into a 5% solution based on wood glue. A homemade solution, mixed until smooth, hardens quickly and should be used immediately after preparation;
Gypsum-chalk putty, mixing
- To level a wooden facade, it is advisable to use an oil mixture, in the production of which a couple of kilograms of drying oil and four kilograms of chalk are mixed, with the addition of a quarter kilogram of drier. The mixture brought to a boil must be cooled to room temperature.
What are driers
Construction chalk, calcium carbonate
It should be remembered that the consumption of self-prepared putty will be higher than when applying ready-made factory-produced mixtures.
Preparation of working tools
To carry out puttying work, you will need to purchase some tools to make application easier and get the most even, smooth surface:
- a fairly wide brush with soft bristles or a roller, with which the façade surface is primed;
Maklovitz brush
Rollers for priming walls
- a construction mixer or electric drill with an attachment for high-quality mixing of the putty mixture;
Construction mixer
- Several spatulas of different sizes allow you to process large areas of the facade, as well as corners or hard-to-reach areas.
If paint is to be used as the final finishing of the facade, then the surface must be absolutely flat and smooth, so a well-dried layer of putty will need to be rubbed with a special fine-grained mesh.
Mesh for grouting putty
Surface preparation
Regardless of the type, the putty must be applied to an absolutely clean, dry and pre-primed surface. It is best to use primer options for putty, which will avoid plastering the surface. Universal primers can be used on any surface, but many experts consider such materials to be ineffective, so they prefer to use special compounds:
- antiseptic primers protect the surface from fungus;
Antiseptic primer for interior and exterior work
- anti-corrosion primers prevent the appearance of rust on metal surfaces;
Alkyd anti-corrosion primer GF-021 GOST 25129-82 for metal
- alkyd primers are good for treating wood;
Alkyd primer for wood “BASE”
- acrylic primers are best suited for concrete and brick;
Acrylic primer
- Phenolic primers are optimal for metal surfaces.

Step-by-step instructions for preliminary preparation of the facade surface for applying the starting putty layer.
Step 1. We remove all external facade decorative elements and antennas that may interfere with the priming process.
Step 2. We fix all loosely fitting elements to the façade surface or remove them completely.
Facade surface preparation
Step 3. We clean the outer surface of dust accumulations with a wet or dry brush with medium-hard bristles.
Facade cleaning
Step 4. We remove heavy dirt and layers of fatty deposits on the surface with a damp cloth. Too much dirt and paint residues can be removed with solvents, after which the surface is washed with clean water.
Step 5. Using a construction roller, carefully apply the prepared primer solution in a thin but uniform layer.
Spraying primer
Brush priming
Roller priming
Depending on the composition and weather conditions, the drying process of the primer can take from four hours to a day or more.
Starting layer application technology
Starting mixtures are coarser and coarser. They are used for rough finishing of facades and have good adhesion to concrete, lime, brick and other substrates. Allows you to fill seams, deep cracks and other large defects.
Starting putty - what is it for and what is it good for
Depending on the initial state of the facade, the working solution can be applied in a layer of several millimeters or centimeters. It is recommended to apply the starting solution thinly, but in several tiers. In this case, it is possible to obtain a higher quality finish.
Step 1. We dilute cement and gypsum putty compositions with clean water in the proportion recommended by the manufacturer. Polymer compositions are ready for use and only need to be mixed before application.
Putty solution
Step 2. We take a small amount of working solution onto a construction spatula, and then apply it to the surface with a sweeping and fairly wide movement. During the application process, the spatula must be pressed fairly tightly to the surface at a stable angle of inclination.

Step 4. After the solution has hardened, we perform thorough grinding, which allows us to get rid of minor defects and makes the surface even and as smooth as possible.
Grinding
Facades with strong unevenness need to be leveled in several steps.
Quickly hardening self-made compositions or solutions diluted from dry ready-made mixtures cannot be stored. They are used as quickly as possible.
Features of finishing putty
Main features of applying putty to the wall
The composition of the finishing putty mixtures is represented by fine-grained fractions, due to which the processed structure acquires a smooth and durable structure. Coarse-grained putties based on quartz sand or marble chips can also be used, designed to create a relief and highly decorative texture of the facade.
In recent years, the most popular way to decorate the façade of buildings is to use putty, which is subsequently pigmented with high-quality coloring compounds. Quite often this method is combined with facing work using natural or artificial materials.
Leveling the finishing putty
Finishing putty will improve the quality of subsequent decorative finishing.
Facade putty can be applied not only manually, but also mechanically, using special equipment. The disadvantage of mechanical application is the lack of the most even application.
Main manufacturers
Putties on the domestic construction market can be presented by both foreign and Russian manufacturers. Of particular interest to consumers are mid-price products with high product characteristics.

Putty work can be done independently even if there is no construction experience, but in this case the following recommendations should not be neglected:
- the surface of the facade must be prepared in advance, cleaned with a brush with metal bristles and thoroughly primed;
- moisture-resistant, frost-resistant and relief putty mixtures can be applied to the facade surface only at positive temperatures;
- at low temperatures, winter putty such as “Rusean”, “Kreps” and “VGT” should be used;
VGT putty
- puttying technology may vary depending on the type of material, but the simplest and most affordable way is to apply along beacons, which will allow you to obtain a layer of optimal thickness;
- under each putty layer, a deep-impact primer solution must be applied, which helps to increase adhesion between the base and the applied composition;
Choose primer and putty from the same manufacturer
- The putty mixture for painting the facade should be white, since gray putties can negatively affect the decorative properties of the finish.

Putty ingredients
High-quality putty has high moisture and frost resistance. Almost any type of it contains the following components:
- Cement or plaster;
- Modifying additives in a fixed number;
- Mineral fillers;
- Plasticizers.
Often, in construction and repair work, putties with a large amount of glue are used (mostly PVA, but often animal, flour and carpentry types). It may also contain ordinary laundry soap, drying oil, varnish, plaster and chalk. Depending on what kind of work will be carried out, choose mineral putties, latex mixtures, acrylic, etc. An excellent universal option is a combined facade putty, which is suitable for leveling and preparing for further finishing of almost any surface, allowing you to apply a layer of any thickness and cover even large flaws on the walls. It does not flake or crumble over time under the influence of harmful external factors. such as temperature changes and high humidity .
How to make the right choice?
Video about facade putty
Properly selected material, based on the characteristics of the wall surface, weather conditions during the year and your budget, is the key good result and the strength of the surface of your walls.
Let us highlight the main types of putties, their strengths and weaknesses.
Acrylic putty
Acrylic facade putty is ideal for surfaces with low vapor permeability. Most often it is applied to polystyrene foam insulation or polyurethane foam insulation. These materials themselves have low vapor permeability. Acrylic putty has high plasticity. When you cover the surface with it, then practically no additional actions are required to clean it over time, because it also has an average or above average self-cleaning rate.
At correct application This putty gives excellent vapor permeability, but requires further painting of the surface. Among the main advantages of this type of putty, we highlight the following:
- Lightweight and easy to apply;
- Quick drying;
- No cracks during the drying process;
- There is no need to dilute acrylic putty with water before use.
For most cases, acrylic putty becomes the best option when you need to quickly and effortlessly level the walls and prepare them for further processing.
Frost-resistant mixture
If you live in regions with low temperatures, then in this case the most reliable option is frost-resistant facade putty . You must understand that temperature (both high and low) has an extremely negative effect on the surface of the walls. And if you choose the wrong material, then after just six months you will have to repeat the same work again.
As in the case of acrylic putty, frost-resistant putty is also easy to apply and at the same time goes well with different types plaster. In fact, it can be used in any weather conditions. This is one of the most reliable, versatile and practical materials to date. Often, frost-resistant putty is used to seal cracks in walls and for obvious problems with the facade, when other options are not suitable. It costs a little more than, for example, moisture-resistant, but the effect of its use is much better. Heat-resistant putty is also similar in its quality characteristics, which is an even more versatile option. But it should be used only if the temperature changes are really sharp and have a large interval.
Facade finishing
Facade finishing putty plays an important role in finishing work. As a rule, this is a dry mixture with high plasticity rates. It is intended for final finishing of the base with a thin layer of material. Most types of it are suitable for eliminating small defects, cracks, and grooves up to 0.5 cm deep. It is used both outside and inside buildings, both in residential and industrial premises. An excellent option for repair and construction work in conditions of high humidity. Finishing facade putty is also ideal for finishing interiors and facades to create the desired texture.
Other types and compositions of putties
Video of façade putty
One of the main components that affects the quality indicators of any putty is binders. Most often it is gypsum or cement. They are suitable for different purposes, and your task is to understand which putty is right for you.
Cement putties have high moisture resistance and are not only good material For outside facade, but also for rooms with high humidity. But they don't breathe well. Therefore, if you want to use them not only on the outside of the facade, but also inside the room, we do not recommend doing this. TO weaknesses cement putty must first of all be attributed to the relatively long drying time. Depending on the surrounding temperature and humidity, it can take 1, 2, or even 3 days to dry. And you can sand it only when it is completely dry. But there’s no point in delaying this either. If you miss the moment and postpone the finishing to the future, then after a month the surface will harden so much that it will practically not be amenable to any treatment.
Polymer or gypsum putty - far from the best option for finishing the outside of the facade. They are more suitable for finishing indoor surfaces. Polymer putty is more flexible than gypsum and, especially, cement. But in our climate zone it is better to refuse to use it for external decoration of wall surfaces.
There is also gypsum cement putty, which, although more expensive, combines the best properties of gypsum and cement, and is excellent for finishing work for various purposes, which makes it one of the most versatile. This is a dry mixture that is simply mixed with water before use. But for use on the outside of the facade, it is not the best option, because it has poor resistance to negative weather conditions. This is an excellent option for interior finishing of facades and preparing walls for wallpapering.
Widespread now water-dispersion putties. They are well suited for both indoor and external works, being at the same time the best option for beginners in repair. They are sold ready for use in plastic buckets. True, they cost more than all the others, but you will have absolutely no problems using them. Such compositions have precise viscosity control, while ensuring excellent smoothness and strength of the wall surface coated with them, which greatly simplifies further painting and reduces waste of the paint itself. Even if you do not have the skills to work with a spatula, you will receive a fully prepared surface of the facade walls for further finishing in a maximum of three approaches.
The cheapest putty to date is oil-glue. But the feasibility of its use is increasingly being questioned. Many builders say that it has already outlived its usefulness. One of its components is drying oil, which some even consider dangerous to human health. Actually this is not true. But for the surface of the walls that you will paint after such putty - very much so. The fact is that drying oil seeps through concrete and paint. As a result, stains will soon appear on your facade, which can only be removed with an additional layer of paint. And even then there is no guarantee that the drying oil will not bleed through on the new layer.
But if you have a wooden facade, then this is a pretty good option. Oil-adhesive putty perfectly protects wood from rotting and nails from rust. Therefore, we would not recommend renouncing it once and for all.
Facade putty for painting
Any builder will tell you that interior and exterior wall decoration are radically different, both in the materials used and in the method of application. Modern manufacturers of materials for exterior finishing with putty reinforce the material with a number of synthetic resins. In most cases, it is a powder mixture that forms a free surface after application. Facade putty for painting with a high resin content is extremely resistant to weather conditions and promotes proper air circulation. Thanks to this, it dries quickly and has a high degree of hydration.
In most cases, the best option is to putty before further painting facade - cement-based composition. It is quite easy to apply and durable once dry. Experienced builders It is recommended to apply fiberglass or fiberglass mesh to the surface immediately before painting. Although this method is more often used for interior finishing work, it will not be superfluous on the outside of the facade. But the most important thing is not to forget that before painting, the facade walls must be primed, which will significantly improve the quality of the final painting and simplify the process itself.
If you have started a serious façade renovation, you must understand that materials that differ in quality (and price, respectively) do not combine well with each other. If you have chosen expensive material from one manufacturer, you should not switch to a cheaper alternative during the work process. When you choose a manufacturer, take all the materials it produces: putty, glue, dry mixtures, primer, and so on. This way you will completely protect yourself from problems with incompatibility of materials and, as a result, additional costs. If you see that you can’t afford to buy everything you need from one manufacturer, it’s better to lower the bar and find a less expensive alternative, but so that the components are completely compatible with each other.
Acrylic putty for facades is a ready-made mixture that is used to cover a previously prepared and very smooth wall of a building. Almost any putty for facades, dry or liquid, must be applied in a small layer, no more than 2-5 mm, therefore, before finishing buildings with putty, it is necessary to finish the walls with any plaster mixtures.
We previously wrote about why façade plaster is needed and recommended bookmarking the article.
Preliminary wall finishing and why it is needed
The average cost of a bag of dry putty is $14-15 (acrylic putty is slightly more expensive), and a small bag of cement costs less than $5, so it’s clear why it is necessary to pre-finish building facades. It is worth saying that cement-sand plaster has excellent adhesion to “wet” finishing building materials. This quality allows the plaster to be used with almost any type of building decoration.
Detailed video tutorial on the technology of installing a “wet” facade
Let's consider the entire set of “wet facade” complete with insulation. In this case, the walls are treated with a deeply penetrating primer so that the adhesive for the insulation has excellent adhesion to the coating. Then the foam insulation sticker is applied.
Wall putty scheme
On next stage it is necessary to putty with starting putty, then glue the foam with glue like Ceresit CM-11 ( in fact, this is facade plaster). Reinforcement is also performed plaster mesh made of fiberglass. Thus, the wall covering is leveled, and the consumption of putty for the facade is minimized. This will significantly save money on finishing the house.
We previously wrote about applying façade primer with your own hands and recommended bookmarking the article.
Before any wet finish is applied, a primer is applied to the surface to ensure excellent adhesion. After the primer has dried, you can begin applying façade putty and painting the surface of the walls.
Acrylic putty has a high consumption
Undoubtedly For plastering on insulation, acrylic putty for the facade is also ideal, but at the same time its consumption will increase at least 3 times. After all, first you will need to seal absolutely all the seams and glue, and then seal the mesh for the plaster. It’s easy to imagine how much material will be needed if the façade putty is applied directly to brick wall or when the wall is aligned with beacons.
At the finishing " wet facade“There are some features and rules that allow you to minimize the consumption of expensive building materials. Using this cladding method, it is possible to perfectly decorate a building, create comfort inside it, and achieve good thermal insulation. Today, many people use this type of building decoration because it is very effective, economical and practical.
Finishing putties
Before applying the finishing putty to the walls, you need to know the features of this building material. When choosing, you need to take into account what the rough surface is like. better type putty, paste, dry powder, which can be either oil or adhesive, latex, acrylic or a combination.
Types of putties
Plasters differ in composition and texture
The Ceresit company is a leader in the production of facade putties
Today putties are mainly produced from silicone, silicate, acrylic, and they can also be combined. We can confidently say that the best putties and adhesives are from Ceresit. To perform puttying, use a metal or stainless steel spatula of the required width. It is also called a “facade spatula,” although it is also used for interior construction work. If necessary, the dried solution can be processed sandpaper or diamond mesh.
For putties used for exterior finishing, the main condition is high quality binding materials - acrylic, silicone and minerals, which are responsible for the hardness, impact resistance and moisture resistance of the putty.
We previously wrote about creating rustications for cladding the facade of a building with your own hands and recommended adding this article to your bookmarks.
It is worth saying that when working with these building materials there are absolutely no toxic odors, they are absolutely harmless to health.
Not any finishing putty, even the highest quality, can be used for exterior finishing. For example, the Vetonit powder mixture is excellent for finishing indoors, but it cannot be used for exterior finishing or even for finishing rooms with high humidity (for example, baths).
Application Features
Let's look at how to apply acrylic facade putty and dry mixture to already prepared walls.
It is preferable to use a mixer to prepare the mixture, but you can stir the putty by hand
When using dry putty for finishing, you need to take 1/3 of a bucket of water and pour the powder into it, then mix the mixture thoroughly using a mixer or a low-speed drill until the structure of the mixture reaches a consistency reminiscent of mashed potatoes. Then you need to wait until the mixture sits for 5 minutes and beat it again. Only after this the solution can be applied to the wall.
Finishing
When finishing the facade, the putty solution is applied to the wall with the usual wide spatula, but at the same time the mixture is pulled out of the bucket with a narrow spatula 7-15 cm, after which it is applied to the entire blade of a wide spatula. It all depends on the skills and skill of the worker. Someone treats the coating with one spatula so that after that there is no need to sand it. Some people use it in their work to speed up the application process. building code, and then finishes the plane with a spatula.
Finishing the façade with putty
The most important thing when finishing is not to stop the process of applying any plane, that is, any area on the wall should not have joints with the undried area that was applied earlier, so that after completion of the work there are no seams on the surface. Transitions to any protrusions on the wall, as well as the finishing of another wall, have nothing to do with this.
In conclusion, let's summarize
Worth paying Special attention to ensure that the finishing putty for the facade is used for its intended purpose and economically, because this is the only way to achieve excellent results. All building material manufacturers' instructions must be followed. There is an opinion that “wet” finishing can be applied to a wet wall - this opinion is erroneous and subsequently leads to cracking of the finishing layer.
Facade putty can add elegance and style to your home
Home covering wet finishing will create comfort and a magnificent view of the house that will delight the eye long years. Modern finishing materials make it possible to complete almost any job in the shortest possible time. The most important thing is to use it in your work quality materials and professional construction tools.
