Repair of plaster door slopes. Do-it-yourself plastering of door slopes: tools, steps, recommendations

Plastering a doorway or window is enough labor-intensive process. For those who do not have the necessary knowledge and skills, in this case it is better to invite specialists. And for those who want to do everything themselves, this article will tell you how to do it.

A slope is a part of a door or window opening that frames the door or window on the sides and top.

Plaster, in this case:

Ideally levels surfaces.
Reliably protects them from destruction.
Makes the room much warmer.

After installing plastic windows or replacing door frame, preparation, and then leveling (see Leveling walls with plaster according to all the rules) and preliminary finishing of the walls, the question arises - how to plaster a doorway or window? The main method of plastering slopes is “under the rule”.

With this traditional way To level the surface, special dry mixtures are used to help give the interior a complete and aesthetic look. In each specific case apply different solutions and technology.

Their choice is influenced by:

Technical characteristics of the object.
How will it be used in the future?
The price of the work.

Different designs and quality of installation of a double-glazed window or door affect the size of the gaps that appear between the wall and the frame.

If their size is more than five centimeters, which can often be found in old houses, the plaster on window slopes applied in two mandatory stages:

Insulation.
Soundproofing.

The space formed between the box and the wall is filled with materials for thermal insulation. Typically, the surfaces are slightly moistened with gypsum mortar, and then compacted along the entire perimeter of the door, leaving up to three centimeters, which are filled with the main mixture. If, after installing the structure, sounds are strongly audible from the street, the gaps are filled with additional soundproofing materials.

Correct installation of windows and doors virtually eliminates gaps, and existing ones are filled polyurethane foam. After the foam has dried, the door slopes are plastered and further finished (see How to finish the front door slopes).

How to prepare for work

Tip: In order for more light to penetrate into the room, the slopes should be plastered at a slight angle, which is measured with a special square.

The instructions for preparing slopes for work suggest the following procedure:

The surface is thoroughly cleaned of dirt and dust.
Bituminous and greasy spots, salts that protrude on the planes.
Particular attention should be paid to preparing the corners.
Existing concrete deposits are removed.
The masonry seams are cleared to a depth of one centimeter, which will ensure good adhesion of the material to the main surface, and the plastered corners of the walls will become durable.
The walls are primed with a special primer solution (see Types of construction primers and their scope).

Tip: When plastering walls sandy cement mortar, their surfaces must be moistened with water using household sprayers, rollers or brushes.

Galvanized plaster profiles are attached to MP-75 or Rotband mortar.
Profiles must be aligned in two planes:

relative to the wall;
without shifting the selected position relative to the slope.

If there are several on one wall doorways, you need to simultaneously install the profiles on the extreme slopes, and after the solution hardens, install the intermediate elements, aligning them with respect to the previously installed ones. Aluminum slats are used for this. In this case, the outer profiles will protect the corners from damage and act as plaster beacons.

After preparing the surfaces, you can plaster the doorways.

To do this you will need to purchase:

Ironing iron.
Spatulas.

Tip: For high-quality plastering of surfaces, you need to make a template. To do this, you can use available material, for example, a piece of plastic. The main thing is to ensure that the working part of this structure is sufficiently smooth and sharp.

How to plaster slopes

Before plastering is carried out window openings, video viewing will tell you all the nuances of the work. The “under the rule” method is considered the most popular and simplest, which is suitable for both complete renovation, as well as refining only window or door openings after replacing supporting structures with them.

The procedure for applying plaster is as follows:

A special beacon is installed in the corner of the slope, which will serve to level the surface.
The solution is poured.
The beacon is pressed to the required depth using a level.
The rule of suitable length is placed vertically on the slope so that the wall does not protrude beyond its edge. The element is firmly attached to the wall with dowels and its vertical position is checked with a level.
Excess slightly dried and loose excess moisture mortar, cut off with a half-polish or a regular strip.

Tip: For correct execution process, you must carefully read the instructions for using the solution, how to plaster the slope with this mixture.

After leveling, when the composition dries a little, for about 15 minutes, the rule is carefully removed by moving it along the wall to the side, but not towards itself. This will make it possible to maintain the corners of the required shape.
After the edge has dried, the remaining area is grouted with a mixture.
The remaining slopes are finished in the same way.

Advice: To speed up the hardening of the composition, especially when plastering the upper slope, you should use a dry alabaster mixture.

The video in this article will show you more clearly how to plaster a doorway.

How to finish door slopes

Plastering of doorways is required:

If there is no door in the opening.
The door being installed requires a rectangular opening certain sizes . This is done during installation:

accordion doors;
glass door;
metal door.

Features of the work:

Plastering door slopes is done using two rules.
Application of the mixture is carried out similarly to the finishing of slopes for windows described above.
When preparing a doorway, there is no need to carry out insulation and sound insulation; all gaps are filled with foam for installation.
It is very important to endure correct installation the canvas is parallel to the floor, which will allow you to get a beautiful slope with the correct geometry.
To prevent chipping on external corners door slope when operating the opening, its edging should be pasted over with a special reinforcing strip and covered with mortar.

When plastering door slopes, sometimes a small problem arises that should be prevented in advance. Cracks may occur in areas where the door frame meets the plaster.

To avoid this:

Problem areas should be sealed with acrylic or similar sealant, which can then be painted.
At the junction there is enough sharp knife a groove several millimeters deep is cut, strictly at an angle of 45°.
The groove surfaces are carefully primed.
A strip of masking tape is glued to the door frame so that the sealant lies in a thin and even strip in the slot. It must be applied with a special gun and leveled with a small rubber spatula.
After removing the masking tape, the junction will be smooth and even, it will not crack and have long time aesthetic appearance.

How to level and plaster the corners of an opening

All opening angles are divided into:

Luzgi – internal corners, between two creeping walls or when joining them to the ceiling.
Usenki are external corners formed at the junction of two adjacent walls.

The internal corners are plastered after the mixture has completely dried, which greatly simplifies technological process. In this case, the composition will not “reach” for the grater. Finishing is done on a slightly moistened surface.

Wherein:

A small amount of the mixture is filled with the corner grooves.
The solution is leveled in the same plane with the previously prepared base.
In corners where there is not enough mortar, it is applied with a trowel, carefully leveled and compacted with a trowel.

To create a corner, you can use a special spatula.

In this case:

Using a wooden strip or rule, protruding corners are leveled.
Plastering the corners is done using the method described above.
Before applying the final coating, the surface is well leveled. It should not have depressions or protrusions.
The surface is primed in an even layer.
Covered finishing layer putty, thickness no more than two millimeters.
Leveling the corners with the plaster solution is carried out using a shaped rod or a trowel, which moves with slight pressure from bottom to top. In this case, even cuttings and husks are formed.
When the solution dries, chamfers about one centimeter wide are made on the outer corners. The chamfer can be rounded to the same diameter.

High-quality and beautifully plastered doorways will add coziness to the interior of any room.

If the apartment is being renovated and windows and doors are being replaced, then after installing them the question arises: how to plaster the slopes? To do this correctly, you need to prepare the materials and tools necessary for this process. This work is done at any angle.

Plastering slopes.

Door slopes are finished both from the inside and from outside apartments, and in the second case it will be necessary to use frost-resistant and moisture-resistant materials. For interior decoration special solutions are used for slopes, wide choose which are available in construction markets and in specialized stores.

What materials are needed for the work?

The following materials are used for finishing slopes:

wooden slats— this is the most environmentally friendly material;
polyvinyl chloride (PVC);
plaster mixtures that are specially designed for this work.

Wood is very often used when finishing door openings, and plastic is best suited for similar works on windows, which nowadays are most often made of plastic. Their installation takes no more than a day, and the room remains clean.

Plastering door slopes.

The most durable slopes (and also environmentally friendly) are obtained by using plaster mixtures. They do not need edging and there are no joints. They are convenient to use during repairs new apartment when produced plastering work on the walls, which takes a lot of time.

Plastering slopes is classic way their finishing. Often it is necessary to cover arched surfaces on doors and windows, and then this finishing method may be the only one suitable for implementation, since plaster makes it possible to finish slopes of any length and width.

How to plaster slopes with your own hands?

After they are collected necessary tools and materials, the work process begins. If the work is started from scratch, then the first step is to install the door frame and carry out plastering work on the surface of the walls of the room. Then they move on to the door slopes.

Tools required for plastering work.

The technology for its implementation is as follows:

First you need to check the strength and reliability of the door installation.
A solution is prepared for plastering the opening, which is made in a ratio of one part cement and three parts sand.
Place a wooden strip on the corner.
A template of the required width is made from durable sheet material, such as cardboard, plastic or iron. It is used to trim the layer of plaster applied to the surface of the slope. To do this, install wooden or metal slats on the sides of the doors, apply the mixture, pressing the made template against them (it is drawn from the bottom up).
Level the plaster layer.
Using a plumb line and level, check the verticality of the created surface.
If the door is not needed in the opening, then you will still need to trim the slopes. In this case, they are mounted on both sides metal profiles- squares, which will then serve for additional protection corners from shedding and mechanical impact. An empty space is formed between the profiles, which is filled with plaster solution. Excess is immediately removed. When the mixture has dried, you can begin finishing the surface.
If there is an arched opening, you need to side surfaces plaster in the same way as described above for the doorway without installed door using metal squares. The rounding of the arch is processed like this. On the already made side slopes, markings of the edges of roundness are applied. It is then reinforced with wire mesh or reinforcement. We need to make templates from plywood. You will need two pieces on which the desired arch radius will be set. The templates are reinforced with dowels. A void is created. It is filled with polyurethane foam, on top of which the plaster mixture is applied. The radius of the arch is determined using templates using a semicircular tool - a half-tera. After the plaster has completely dried, they begin to paint or paste the curve, having first removed the templates and applied putty to its surface.
If after this work you need to paint the walls and slopes or cover them with wallpaper, then first all these surfaces are puttied.

How long the door frame will last depends on the quality of plastering of the slopes. Let's figure out how to quickly and efficiently plaster door slopes yourself and how to save money on doing this work yourself.

Plastering slopes – necessary work on finishing the doorway after installing a new door frame. The quality of finishing of the slopes directly determines the appearance, and the trouble-free service life of the door. To do these jobs correctly, you need a certain skill. But it is still quite possible to plaster door slopes with your own hands. Let's figure out how this is done.

Why are slopes trimmed?

First of all, let’s find out what problems slope processing should solve. This operation is performed due to a number of reasons:

Preservation of heat and protection from extraneous noise. A layer of plaster hides all the cracks, so warm air no longer blown away by drafts. It is also more difficult for extraneous sounds to enter the room if the slopes are properly sealed.
UV protection. Ultraviolet rays found in sunlight gradually cause degradation of the polyurethane foam. The layer of plaster prevents the impact of UV rays on the polyurethane foam, which means the durability of the door and door frame increases.
Finishing and giving a complete look. Sealed slopes have a much more aesthetic appearance. Therefore, only after completing the plastering work can we definitively say that the door is installed in place.
The basis for further finishing work. To install panels or paint a wall, you must first carefully level it, remove all differences in height, cracks, and cavities. These tasks are performed by plastering work.

That is why, after installing the doors, it is necessary to finish the slopes with the utmost care. It is quite possible to handle this work on your own. But you need to prepare everything you need and master the technology for performing the work.

Selecting materials

To create a layer of plaster, you can use various construction compounds. All components for their manufacture can be purchased at construction stores. Here are the most common options for solutions for finishing slopes:

A mixture based on cement and sand. A classic plaster material that fully meets the “cheap and cheerful” principle. It is quite simple to make: take part of the cement, mix it with water (it needs a little less in volume) and mix it with three to four parts of pitch. The amount of sand is selected according to the concentration: it should resemble thick sour cream.
Slopes finished with a cement-sand mixture do not look very aesthetically pleasing. Therefore, this option is most suitable as a basis for subsequent finishing.
Cement-sand composition with the addition of alabaster. Alabaster, gypsum and other similar additives allow the finished substance to harden faster; in addition, the solution becomes more plastic.
Ready-made mixtures for plastering slopes. As an example, let's name mixtures from the Knauf company: Rotband gypsum plaster and MP-74 mixture. But you can also take mixtures of similar purposes produced by other manufacturers. The advantage of this choice is good qualities solution and a fairly aesthetic appearance finished surface. The downside is the higher price.

It is difficult to definitely recommend one or another version of the mixture for plaster. The choice is made based on the budget allocated for these works, the personal preferences of the master and the purpose of the finished surface (i.e. whether subsequent fine finishing or not).

Required materials and tools

For the job to go smoothly, it is important to have the right tools to complete it. Let's figure out what you need to plaster slopes with your own hands and how to choose the right tool.

First of all, you will need to prepare the level. It is better if there are at least 2 ampoules on it. When choosing a length, it is better to choose a tool about 1 m long. A shorter one will be inconvenient to work with (you will have to shift it too often and there is a higher risk of creating “steps”), and with a long tool it will be impossible to turn around between the walls and the jamb.

For marking you will need a tape measure (a 2-meter tape measure is enough) and a simple pencil with a protractor. To bring out the surfaces in an optimal way, you will need an aluminum rule.

To prepare the solution and apply it to the wall, you need to prepare:

A vessel for preparing the mixture.
A measuring stick for measuring volumes.
Dishes for water.
Tools for applying the finished mixture to the walls: a spatula (5 cm), a trowel (the kind used by masons), a trowel and graters (if you plan to plaster with cement-based mixtures). If you plan to use gypsum-based mortar, instead of a trowel and floats, you will need a wide spatula (45 cm), a trowel and a grater with a sponge base.
Hammer-pick.

You will also need to take care of protective equipment. Mixtures based on gypsum and cement have a very aggressive effect on the skin of the hands. Therefore, you need to take care of gloves (a medical sample will be enough). You will also need a work coat or other protective clothing. To avoid dusting your eyes and hair when working, you should also choose a hat and safety glasses.

Another aspect safe work– reliable support for the feet. Avoid working from wobbly stools or chairs. A reliable stepladder – already a little more suitable option, but it will have to be rearranged often, and your legs will get tired from working in a narrow area. Therefore, if possible, it is worth putting together comfortable sawhorses.

Preparatory work

Work on plastering slopes must be carried out as carefully as possible. The door, when closing and opening (especially with sudden impacts), transmits vibration to the frame, so poorly applied plaster can simply fall off. Therefore, if you want to avoid the need for repairs for as long as possible, you need to complete all the work as carefully as possible and prepare the walls well for work.

The door frame is installed even before finishing work on the slopes begins. This way the structure will be more durable, and there will be no need to fill the gaps between the wall and the slopes. When installing, be sure to use a level to check that the box is as level as possible vertically and horizontally. If necessary, use wooden wedges for adjustment.

Before starting work, do not forget to protect door leaf and jambs from getting hit building mixtures. You can seal the protected surfaces with tape, cover them with newspapers or plastic film.

First you need to prepare the surfaces in draft. To do this, old plaster and pieces of bricks protruding beyond the slope are removed. You can beat them off manually or use a hammer drill.

The next step is to remove dirt and cement mixture residues. Use a wet rag or spatula to remove all deposits from the brick or concrete slab. The more carefully this stage is completed, the less the risk that the plaster will fall off along with the dirt.

Before applying plaster, you need to wait for the cleaned walls to dry thoroughly. Only then can you begin plastering work.

How to plaster door slopes. Step-by-step instruction

Doing plastering work on door slopes with your own hands is not very difficult. But the technology must be strictly followed. Here are the basic steps to work with:

We evaluate the surface and determine approximately how much solution will have to be applied. If necessary (if you have to put a lot of mortar), a mesh with 10 by 10 cm cells is nailed to the wall. The mesh will allow the mortar to lie more evenly and hold more firmly.
The slope is strengthened with an angle made of perforated light alloy aluminum profile. The corner is fixed with cement mortar and leveled so that its edge does not protrude from the wall. The squeezed out solution is removed.
Protruding fragments of polyurethane foam are cut off with a knife and protected from moisture. To do this, a layer of vapor barrier sealant or film is applied to it.
The surfaces are treated with a primer so that the plaster adheres better. The type of soil is selected based on the plaster composition used and the wall material.
After the surface has dried thoroughly, begin plastering. Apply the mortar onto the wall using a spatula and level it, removing excess mortar. You need to pay special attention to the condition of the corners. Typically, plastering is carried out in two stages: rough and finishing. Enough time should pass between the two stages for the solution to set well. You can wait even a day.
When the finishing layer dries, the plaster is thoroughly rubbed, achieving a smooth surface.

By following these steps, you can get perfectly smooth slopes with your own hands.

Every business requires practical experience. Therefore, advice from craftsmen who perform finishing work professionally is especially valuable. Here's what professional finishers advise:

Finishing the slopes is an important stage, the quality of which directly determines the service life of the door. But if you study the technology and prepare everything you need, you can do it yourself even with minimal finishing skills.

Implementation repair work in a house or apartment on your own is a less expensive undertaking than when you invite specialists. But if you do not have the appropriate knowledge and skills, the likelihood increases that such repairs will not last long.

To the number compulsory work refers to the design of door slopes. They are often plastered. The appearance and service life of the doorway depend on how well their restoration is carried out.

Why do you need to plaster slopes?

Many people consider the procedure of plastering door slopes to be a waste of time and money. However, the opinion is wrong.

This operation is performed for the following reasons:

The plaster layer serves as the basis for further installation of panels, painting of walls and other finishing. Using this procedure, all flaws are removed: the surface is leveled, cracks and cavities disappear, and height differences are eliminated.
Plastering the door slope gives the opening a finished aesthetic appearance.
If done well, a plastered door slope will last a long time. It will be protected, firstly, from ultraviolet rays, which, acting on the polyurethane foam, cause its destruction. Secondly, from extraneous noise and heat loss, since even the smallest cracks are sealed with plaster.

Therefore, this stage of repair cannot be omitted.

Tools and materials

The quality of finishing depends on the choice the right tools and materials.

For plastering you will need:

building level . Preferably, a length of no less than 1 m and no more than 2 m. With a short one, there is a possibility of creating “steps” due to frequent movement, and with a long one, it is difficult to turn around doorway. It would be good if this instrument had two ampoules;
two-meter tape measure and pencil to make the necessary marks and markings;
container in which the solution will be mixed, as well as measuring containers to accurately determine the required volumes;
tools for applying plaster mixture on the walls: a five-centimeter spatula, a trowel, a trowel and graters for cement mixtures or a forty-five-centimeter spatula, smoother and sponge grater for gypsum mixture. You will also need a hammer pick and an aluminum rule.

The performer of such work should take care of his equipment. Required: protective hand gloves (medical ones are also suitable), a hat and glasses, overalls or a work coat.

Also, to safely perform plastering work, it is necessary to prepare reliable support for your feet. Not wobbly stools and chairs, but a reliable, stable stepladder. Or knocked together sawhorses with a wide platform, since your legs will quickly get tired on a narrow one.

Various mortars are used as plastering materials. Compositions can be purchased at finished form or knead it yourself:

Cement-sand mixture. This solution is “cheap and cheerful” and is suitable for a rough base. For one part of cement diluted with water, take three to four parts of sand. After combining the components, the consistency of the solution should be like thick sour cream.
Cement-sand mixture with the addition of alabaster. It has advantages such as ductility and faster curing.
Ready-made plaster mixtures. After drying, they are more aesthetically pleasing, but expensive.

Problems that may arise

Before you start plastering the door slopes, you must:

Check the quality of installation of the door structure. It does not matter whether this was done independently or with the help of a third party. If defects are discovered in the future, the plastered areas will have to be destroyed.
Pay attention to where it is held electrical cable. In old buildings it starts under the frame front door. It is easy to damage during the work.
Install in premises that comply with standards temperature regime and humidity.

If everything meets the requirements and problems are prevented, then you can start plastering.

Technology

Despite the length of the stages, the work is not difficult. The main thing is to follow the technology. High-quality plastering will ensure a long service life of the doorway.

Preparation

The first thing you need to pay attention to is preparation work surface. Otherwise, the plaster layer may fall off.

Plastering is a fairly messy process. It is recommended to protect surfaces that cannot be repaired (door, walls, floor) masking tape, film, oilcloth, newspapers.

If the cracks are not foamed after installing the door, then this should be done at this stage. The surface must be moistened with water from a spray bottle, and then applied with mounting foam, which, swelling, will fill the voids. After final hardening it should be cut off. stationery knife.

All leftovers old plaster must be removed, even if it sticks well. Then treat greasy, oily stains and traces of old paint with neutralizers, since the composition adheres very poorly to them.

After this, remove construction dust and dirt with a damp cloth or roller.

Installation of beacons

Aluminum profiles or wooden slats are usually used as beacons. They are fixed on in the right place using a thin layer of mixture or self-tapping screws. When installing, it is important to use a level to ensure that the door slopes are level.

Creating notches

With the help of a hammer, notches are quickly and evenly applied; it acts as a building level. To make it, you need to prepare an even strip, the length of which is slightly greater than the depth of the slope. You need to drive a nail into it from the end, leaving a tip of about 0.5 cm, removing the head, which can leave marks on the surface of the mixture.

Plastering door slopes is usually carried out in two stages: roughing and finishing.

Rough plaster of slopes

The process of applying plaster is the same on any surface. It’s better to start from the bottom, slowly working your way up. Carefully spread the mixture onto the prepared and slightly moistened surface using a spatula.

Then, moving the aluminum rule from side to side and smoothly rising upward, they make zigzag movements. Distribute the mixture evenly over the surface, promptly removing excess.

If the solution does not adhere well to the surface or it strongly absorbs moisture, then treatment with a primer or tile adhesive will be required.

When plastering the upper slope, the solution should be applied with a wide spatula, pressing it and pulling the mixture a little along the way. In this area, you should not rush and apply a lot of composition at once. It's better to spend more time and do it well.

Finishing layer

The rough layer needs to dry for some time, usually one day. Only after this do they begin finishing plastering. At this stage Special attention You need to pay attention to leveling the surface.

The solution is kneaded to be slightly more liquid. They apply it thin layer and smooth, removing excess. If voids appear, then a little mixture is applied to them again and leveled.

Grout

After the plastered surface has completely dried (after about 16-24 hours), grout it so that it becomes perfectly smooth. This will require a grater and even more liquid solution. The mixture is applied to the surface and, making circular movements with a grater, distributes evenly.

This step is optional, but after it is completed the slope will have a finished appearance.

Finishing work

Depending on the type of further finishing of the slope (painting or wallpapering), the volume is determined finishing works:

To paint, the wall is puttied in two perfectly aligned layers, each of which needs to dry.
To paste wallpaper, you can putty the surface in only one layer.

Plastering arched slopes

The peculiarity of plastering arched door slopes is their bending, which requires the installation of special auxiliary structures.

The side parts of the arched opening are processed in the same way as usual - profiles are installed, mortar is applied and leveled.

For the upper rounded part, you will first need to apply the boundaries of the arch to the finished slopes, which are reinforced with wire or thin reinforcement. A template of an arched opening with a given radius of curvature is cut out of plywood and attached to the wall on both sides.

The void is filled with polyurethane foam, and after drying, a solution is applied to its surface. Using a semicircular trowel, based on templates, the solution is distributed and leveled, repeating the required radius of the arch. After complete drying, the templates can be removed and proceed to finishing.

High-quality execution finishing work directly depends on experience. Some advice from professionals:

You should select and use only high-quality and proven materials and tools.
Follow the technology for carrying out this type of work and do not neglect any stages, saving time and money. Also observe temperature and humidity conditions.
Be sure to use a building level.
When installing the corner, cut the edge adjacent to the main wall at an angle of 45 degrees so that it does not ride up.
When leveling the mixture, make zigzag movements from bottom to top.
Wait for each layer of plaster to dry.

Plastering door slopes is one of the simplest stages of finishing work. But certain knowledge and skills will be required. Therefore, if you are not confident in your abilities, then it is better to use the services of professionals.

Video

It is not enough to simply install windows or doors: you need to give the opening an aesthetic appearance. The simplest and inexpensive option is plastering slopes. If the work is done correctly, the opening will be provided with thermal insulation and moisture protection.

Well-made slopes have the following characteristics:

ensuring waterproofing of the installation seam;
resistance to abrasion during cleaning;
resistant to temperature and ultraviolet radiation;
provide thermal insulation.

According to the form of manufacture, slopes are: oblique and straight, narrow and wide, external and internal.

Necessary tools and some activities before starting work

To perform the work efficiently, you will need the following tools:

water building level;
fry;
pencil for marking;
narrow and wide spatula;
container in which the mixture is prepared;
rule;
Master OK;
hammer;
grater, grater or smoother.

Plastering slopes requires special tools

Before you start plastering, you need to prepare your workplace.

To begin, cover the window sill with film, cloth or cardboard so that it is not damaged during plastering. Then you need to protect the double-glazed window: to do this, you can simply glue the film onto the glass using tape. Carefully cut off the remaining foam.

Preparation of mortar for plastering work

To plaster a surface, you first need to prepare a solution. In addition, you need to calculate the consumption of plaster. The binder component in the solution can be gypsum, cement or clay. In addition, there are various fillers, sand is most often used.

Plastering slopes with your own hands can be done either from a ready-made purchased mixture or prepared independently. Buy ready-made composition the easiest way: all the necessary proportions are met in order to obtain a solution that has all the necessary characteristics. Before purchasing, calculate the consumption of plaster.

The easiest way is to prepare a plaster solution from a ready-made mixture

For plastering slopes in wooden and stone buildings You can use a solution that contains slaked lime. Slaking lime is a must, because if you use quicklime, the surface will swell.

For interior decoration in a dry room, you can make slopes with gypsum plaster. Gypsum hardens quickly and dries well. Its disadvantage is that it is hygroscopic, so it cannot be used outside..

The strongest slope will be made of cement. This solution hardens quickly. It is used both inside and outside the building. Clay is used only for plastering in wooden structures.

A cement slope is the strongest

For the filler that is added to the solution, it is most often taken river sand. Sea sand contains excess salt, while mountain sand contains clay impurities. Before use, it is imperative to sift the sand - this ensures the homogeneity of the mixture, which will help to obtain a smooth surface.

Preparatory work

This important stage, since on an improperly prepared surface the plaster will not adhere well and may crack and fall off.

First you need to level the surface. To do this you need to do the following:

check the verticality of the slopes;
the evenness of the walls is controlled; if necessary, they need to be plastered;
in the presence of large potholes, use a special metal mesh, which is nailed to the surface of the slope.

Before plastering, it is necessary to determine the evenness of the walls.

After completing this step, it is necessary to clean the contaminants. For this purpose they use various means depending on the wall material and the type of contamination:

concrete walls are treated with mortar of hydrochloric acid and washed with water;
dirt can be cleaned using a wire brush;
The old paint with which the slope was previously treated must be cleaned off.

After cleaning, be sure to make notches on concrete wall, part of the mortar is removed from the gaps between the bricks - all this will ensure better adhesion of the wall to the mortar. Be sure to prime the surface before starting plastering.

Renewing an old plastered opening

If you choose this finishing option, you need to know that sooner or later you will have to repair the plaster of the slopes inside the building. This will first require removing the old paint, then tapping the entire area of the slope and removing pieces of fallen mortar. All cracks must be cleaned, stains and mold removed. Deep potholes are moistened with water, then with soil and filled with solution. After carrying out this procedure, you need to wait until it dries. After this, you can continue working with the slope.

Stages of surface plastering

Before you get started, you need to know how to make slopes. To do this you need to do the following:

It is most convenient to carry out plastering work on slopes along beacons. To do this, to obtain a beautiful corner, place a paint corner on the outside, which is well secured with a solution. A beacon is installed along the frame, on which the tool will rest to cut off the excess layer of mortar.

After the rough plastering stage, the solution is poured onto the surface in the bottom-up direction. Then they move along the beacons with a rule and remove the excess layer, putting it back into the container.

Scheme for plastering slopes along lighthouses

A plaster mixture is usually spread on the upper slope. If the surface is prepared correctly, then there will be no problems. You can carry out the work with a rotband. This ready mix, which can be purchased at a hardware store.

After the first layer has dried, finish plastering the surface. This will require a more liquid consistency of the composition. The mixture is applied in the same way as the rough layer and stretched using the rule. Now it is important to get a smooth and even surface. After leaving the plastered surface for several hours (about a day), they begin to grout it.

After the plaster has dried, the surface is grouted.

Dilute the liquid solution to such a state that it can be poured onto the surface. The work is done with a grater. The solution is applied to it and distributed over the surface in a circular motion. This stage is optional if you plan to putty the slopes.

Finishing the slopes of the plaster field

If the slope is to be painted, then the plane must be made perfectly smooth. This is achieved by applying two layers of putty: start and finish. The starting mixture has a larger grain and can be applied in a layer of up to 1 centimeter. After the first layer has dried, apply the finishing layer. This layer is thinner; after it dries, it is necessary to grout all unnecessary protrusions and irregularities with a mesh. If you decide to paste wallpaper before painting, then it is enough to stop at the starting layer of putty.

After plastering, you can glue wallpaper onto the slopes

In the case when a window or door was replaced and the slope was not badly damaged, it is enough to restore it, that is, to repair the plaster of the slopes inside the building. This will require less work: it is enough to throw the solution into large potholes and level the entire surface.

Plastering door and arched slopes

Plastering both door slopes and arches is done in the same way as plastering window openings. The same materials and solutions are used; it is necessary to attach the corners to create a hard corner. If the slope is not severely damaged when installing the door, you can repair the plaster of the slopes inside the building.

Before you start plastering the door slopes, you need to prepare the surface. For this they remove old paint, putty and beat off poorly adhering parts of the plaster. Then everything needs to be moistened and primed.

To make it work high quality plaster corners, you can attach a special metal or plastic perforated corner with mesh. It is secured using self-tapping screws or plaster mortar. Once everything is level and secured, you can begin plastering the slopes.

A perforated metal corner is used for plastering corners.

According to the technology, the first layer is thrown onto the surface and left to dry. After this, the surface is completely rubbed and the plane of the slopes is displayed. If you are faced with a very uneven slope and the layer of plaster exceeds one centimeter, you must use a mesh, otherwise cracks may appear on the finished surface.

Carrying out work on upper slope, attach the rail on which the rule will rest. After applying the first layer, you need to take a break to dry, after which you can apply the second layer, which will have a smooth surface.

If doors are not installed for arches, a corner protection profile for plaster is placed on both sides of the opening. After plastering the side slopes, you need to tackle the upper arched slope.

Templates are used to plaster an arched opening.

To do this, you need to measure and cut two arched templates, which are fixed on both sides to the walls. They begin to pour the solution and distribute it special tool– with a semicircular grater. The radius of the arch is derived from the mounted templates. The template must be dismantled after the mixture has completely dried.

Remember that plastering can be carried out in a room where the temperature is at least 6 degrees Celsius. If this rule is not followed, the quality of the slopes will be low..

Carefully read the instructions for preparing the solution that the manufacturer puts on the packaging. The expiration date is also important, since after its expiration the mixture will no longer have required characteristics. The expiration date that is close to expiration may also not have a very good effect on the final result.

When working with plastic windows do not forget to make a groove along the entire perimeter between the frame and the slopes with a depth of 5 mm. After the solution dries, the recess is filled silicone sealant. This ensures that in extreme heat, when the volume of plastic increases, the slope will not crack.
