How to protect brick from moisture. Protection of brickwork Protection of sand-lime bricks from moisture

Brick processing can serve different purposes, for example: cleaning from dirt or impregnation to give the material new qualities. Below we will consider the main processing options for this building material.

Removing contaminants

Most often, brick is processed to clean it from traces of dirt and construction dust. Due to its high porosity, brick is easily soiled, so to maintain the attractive appearance of the material, it must be cleaned occasionally. In addition to mortar residues, the most different types contaminants, including paint, dirt, bitumen, fuel oil, lime, soot, rust.

Often the brick becomes moldy or has traces of efflorescence. It will take a lot of time and effort to remove dirt, since cleaning brick is a very labor-intensive job.

In practice, the question of cleaning the material usually arises after the construction of brick walls made of ordinary or facing bricks. It is also often necessary to clean the mortar from old bricks that have been decided to be reused. The specific method of cleaning the material is selected based on the type of contamination.

The following types of cleaning are commonly used in the construction industry:

high-pressure water jetting;
sandblasting technique;
mechanical cleaning with a tool or manually (hammer, sandpaper, chisel, brush with stiff bristles, hammer drill);
using a special cleaning fluid, which can be purchased locally finished form, so it was made on its own.

Below we will look at each method separately.

Water jet cleaning

A water jet under high pressure (15-220 bar) removes, first of all, efflorescence. Despite this pressure, cleaning occurs very carefully, without damaging the material. In addition, the method is environmentally friendly.

Sandblasting method

Cleaning is carried out using special equipment and under high pressure. During the process, the brick is treated with sand or another abrasive substance.

The purpose of sandblasting is to remove foreign materials and prepare the surface for applying various coatings. The brick is sanded before filling or painting. Thanks to sandblasting, you can clean the brick from old paint, bitumen, fuel oil, plaster, soot and all kinds of substances containing dyes. The result is a clean surface suitable for further processing.

The challenges of sandblasting and finishing are not the same as with surface preparation. The difference is that this technique involves improving the appearance of the product and increasing its performance, and not just preparing for coating.

To confidently use sandblasting equipment, you will need certain qualifications. Therefore, the cost of such work is quite high.

Manual or mechanical cleaning

Typically, the method is used to remove solution residues or other solid foreign substances from the surface of a material. The main tools for cleaning are a drill, sandpaper, a hammer drill, a jackhammer, a brush with stiff bristles, a chisel, and a hammer.

When carrying out work, you need to take care of your own safety, so you will need safety glasses, a respirator, and rubber gloves.

Red brick is cleaned only by hand. To do this, you need to break off pieces of the mortar using a hammer and chisel. After removing large pieces, the crayons are sanded with coarse sandpaper.

Sand-lime brick is stronger, so it can be cleaned using equipment such as a hammer drill or jackhammer. Then, as in the case of red brick, cleaning is carried out sandpaper. The process is completed by soaking the material in water to finally wash off the remaining solution. During soaking, you can additionally use a brush with stiff bristles. The brick must be dried before use.

Chemical cleaning

Based on the type of contamination, a certain chemical composition is used, which can either be purchased or made independently. Also during the work, a tool is used, as with mechanical cleaning.

You can remove cement mortar as follows:

You can get rid of other contaminants like this:

Efflorescence will become less likely if the brick is well dried, there is waterproofing, and drains for waste water.
During laying, work should be carried out carefully to prevent excessive contamination of the material. This will require additional effort, but will further reduce the need for cleaning brick walls.
When cleaning brick, you must not forget about the technological nuances, otherwise you can damage the material.
When working with facing brick or stone, you should use a dry sponge to avoid damaging the surface.
To remove traces of soot on facing bricks, it is recommended to use specialized pastes and household chemicals.

Brick impregnation

The impregnation process is called hydrophobization. The technique can be partially classified as cleaning methods, since in this way efflorescence is removed.

However, the main purpose of hydrophobization is to give the material (stone, brick, concrete, ceramics, etc.) protective water-repellent properties and resistance to low temperatures. When waterproofing, a special impregnation for brick is used. As a result, the material interacts with moisture differently.

Most often, the key component of the water repellent is silicon, although other bases can be used. An example is Kristallizol, one liter of which is enough to treat 150 square meters surfaces.

The drug not only increases the frost resistance of the material, but also increases its strength by about a quarter. The product is often used to protect surfaces in rooms with high humidity(for example, baths and saunas). The drug allows you to block moisture from entering the coating structure and also prevents the appearance of microorganisms, including fungi.

Another important quality of Kristallizol, like any other good impregnation, is that the drug prevents the accumulation of dirt on the surface of the material, which allows you to achieve a greater decorative effect. And finally, the use of impregnation makes it possible to reduce consumption finishing coating(for example, paints).

A good water repellent has a number of qualities:

absence of visible film after treatment with the drug;
environmental friendliness;
fire safety;
neutrality to existing vapor tightness;
durability.

Before use, “Crystallizol” is diluted in water in a ratio of 1 to 30. Then the solution is applied in an even layer to dry and clean brick. For brick, one layer is enough. More layers are needed only for concrete surfaces.

Processing brick to clean it or improve its properties will significantly extend the life of the masonry and improve the decorative qualities of the material. At the same time, one should not forget about timely care of the masonry and periodically clean it from emerging contaminants.

IN modern world ceramic stone is the most common building material. But very often various damage begins to appear on the material due to excess moisture. Therefore, many owners brick houses Over time, people begin to wonder: how to protect brickwork from moisture? This article will talk about this.

Brick itself is a porous material. And the seams between bricks are considered weak point masonry They allow moisture to pass through, causing the wall to become damp. Possible troubles that may arise:

Efflorescence (unsightly salt formations) appears on the wall.
In winter, the wall may freeze.
Heat begins to leave the room.
In autumn, moisture penetrates the seams, and winter time turns to ice.
Under the influence of previous factors, the destruction of the brick and the entire masonry occurs.
The best way out of this situation would be brick impregnation.

What it is? IN Lately impregnation for bricks is the most popular material. This is due to the fact that facing bricks, more than other types, are damaged by salt and moisture, and white salt stains form on the surface of the wall. After treatment with impregnation, the brickwork is completely protected from all of the above adversities and, thanks to this, the brick walls acquire a beautiful appearance and durability. The product penetrates inside the brick to a depth of 1 cm and creates good vapor barrier and a water-repellent layer. The wall will not be afraid of either rain or snow.

Different types of products have different compositions:

The silicone product is two-component and water-based.
Acrylic or silicone-acrylic is based on appropriate ingredients.
Varnish impregnation is made on the basis of a specialized varnish, which gives the surface a slight gloss.
Water-repellent - has high protective characteristics and is the most common type of impregnation.

Each of these types, one way or another, has a water-repellent effect. After applying the product, a thin hydrophobic microfilm is formed on the wall, which well closes the pores of the brick from moisture penetration.

Benefits of processing

The tool allows you to:

Protective properties of the product:

Due to the fact that the brick is reliably protected from water and its involuntary suction, the building material lasts much longer.
The treated surface acquires good frost resistance, increasing the strength of the house by 25%. This is necessary for brick fences, brick pillars, plastered facades and plinths of houses.
Impregnation is an environmentally friendly and fireproof material.

Water-repellent impregnation is often used in saunas, baths and swimming pools. All moisture remains in the room without penetrating into the brick elements of the room. This is why the likelihood of fungus appearing is significantly reduced.

Blends well with brick walls, artificial stone, marble, concrete, gypsum, cinder block and sandstone.

Perfectly complements materials such as mineral wool, mineral paints, cement-fiber surfaces.

Water repellents are often used to treat building plinths and paving slabs;

Experts advise also treating roofs made of ceramic tiles and slate. This will prevent the coating from moss, fungi and mold and the roof will retain its strength and reliability characteristics.

The use of the solution for the facades of ancient buildings and centuries-old buildings is more effective.

Preparing walls for work

Before treating the wall with impregnation, you need to understand the reasons for the penetration of moisture into the house and prepare the walls. These may be poor quality seams brickwork or panel joints. You should be wary of strange stains, the formation of fungus indoors, external damage to seams and green formations.

Repair of such facades can be carried out in two ways:

If the seams are in order, the masonry is simply impregnated with the preparation.
Collapsed seams must first be repaired.

Brick walls should be inspected once a year. Any dirt that appears can be removed with water. If contaminants cannot be removed, use a special paste or mechanical cleaning. You need to apply the paste with a brush, and after half an hour, wash it off along with the dirt. Existing efflorescence must be removed using special solutions, fungus and mold must be treated with antiseptics. The crumbling plaster must also be removed.

Processing principle

Impregnation can also be applied to moisture-impregnated brick walls. But it’s still better to wait a few days after warm and dry weather sets in.

If the seams are in poor condition, you need to pre-seal the seams. Old damaged mortar and damaged bricks are removed. First, the seams are filled with a cement-sand composition, after which the repaired seams need to be sealed special composition. The work is carried out in the following sequence:

The wall is cleaned by removing old mortar in the joints.
The crumbling bricks change.
The masonry is pre-impregnated and time is given to dry.
All seams are sealed.
The wall is cleaned again and impregnated with the preparation once again.

For getting good results Pre-treatment with impregnation requires at least a day. After this, all seams between the bricks are sealed using a cement-sand composition with the addition of sand up to 2 mm. The final stage of finishing the seams is carried out using a board with a sponge, with which the solution is rubbed in as if. Application is carried out with diagonal movements along all seams, using a sponge to remove the solution from the wall until it sets completely. After this, the wall is washed clean cold water, removing the remaining solution.

After finishing the work, the seams must be closed from ingress. sun rays. An additional second impregnation of the wall is carried out after 3 days.

Simple wall treatment should be carried out in dry weather. The second layer of impregnation is applied 15 minutes after the first. There should be a visible shine on the wall. Water-repellent properties on the building facade are maintained for at least 10 years.

Alternative to factory impregnation

Branded impregnation cannot be purchased everywhere. But as an alternative you can use the usual vegetable oil or apply natural drying oil. You need to cover the walls with the heated product using a brush twice. But it takes several days for the preliminary impregnation to dry.

Every owner wants to keep his home in good condition for as long as possible, not to spend extra money on heating the house with a heater and frequent repairs. All these desires can be fulfilled by using brick impregnation. It will quickly and easily rid the house of all unnecessary problems and bring joy to all its residents.

from moisture and destruction, hydrophobization, water-repellent impregnation of concrete,

brick and stone, protection of facades from efflorescence

One of the most important problems in construction is increasing the durability of buildings and structures and reducing the cost of their repair.

Most building materials are highly porous and susceptible to swelling due to capillary absorption of water. Water dissolves salt crystals, which, with alternating wetting and drying, disrupts the structure of materials and reduces their strength. As a result, salts dissolved in water come to the surface of the building structure and form stains on it -, which worsen the appearance of the building and disrupt its heat transfer.

Water is the main enemy of building materials! When water freezes, it increases in volume up to 10%, which creates a pressure of over 200 MPa (2 t/cm²!) in the pores of materials soaked in water. The strongest of building materials, such as concrete, brick and even natural stone, are unable to withstand such internal pressure without the formation of microcracks.

Concrete and red brick can have significant (up to 90%) water absorption. Moisture by concrete wall or brickwork can rise from the ground to a height of up to 2 m, while the heat-insulating ability of the walls deteriorates, efflorescence appears on the walls, mold develops, microcracks form in the material, which ultimately leads to premature destruction facing material and the entire wall structure in general.

Is there a way to protect wall structures from the destructive effects of moisture? Yes, I have!

Today there are reliable means for hydrophobization (moisture-repellent impregnation) of any building structures and materials and protecting them from getting wet.

One of the most interesting innovations in the field of creating new means of effective hydrophobization can be called -

Water repellent KRISTALLIZOL (concentrate) - multicomponent composition on an organosilicon basis.

Hydrophobizing composition CRYSTALLIZOL is absolutely unique material. It is recommended for surface treatment of concrete, artificial stone, mineral plasters, ceramic tiles, sand-lime brick and cement fiber boards. Due to its chemical nature,KRYSTALLIZOL Water repellent , unlike conventional water repellents, can be used when processing wet materials. For example, in the case of working on a difficult surface or in conditions where it is almost impossible to dry it: in attics, basements, etc.

The water repellent KRISTALLIZOL is not inferior in efficiency to the best imported analogues, but costs much less!

Concentrate KRYSTALLIZOL Water repellent used in the processing of limestone, slate, shell rock, brick, concrete, cement-sand plasters, sandstone, gypsum, cinder blocks, CBPB, cement-sand and clay tiles, ceramic tiles, artificial and natural stone, marble, etc.

Concentrate water repellent KRISTALLIZOL is the most economical type of façade protection from moisture. The concentrate is diluted with water 30 times, thus1 liter of concentrate is enough to treat 155 sq.m. surfaces!

Hydrophobization of concrete and brick structures significantly improves them performance: the ability for capillary suction of water is practically lost, contamination of the facade from exposure to precipitation is reduced, and the frost resistance of the material increases.

Water-repellent impregnation almost completely eliminates the phenomenon of capillary suction, significantly reduces water absorption during direct surface moistening and, at the same time, does not reduce the vapor permeability of the surface. The essence of this method is that a very thin layer is formed on the surface of the material.hydrophobic coating , an invisible polymer film that, when exposed to moisture, closes the pores of the material and prevents moisture from penetrating inside.Hydrophobizationalso prevents the appearanceefflorescenceon brickwork, increases the durability of the surface, virtually eliminates its damage by fungi and mold, improves frost resistance, while maintaining the strength and thermal insulation properties of the material.Hydrophobic coatings for concrete protect concrete from atmospheric moisture and prevent concrete destruction during cyclic temperature changes from plus to minus in the autumn winter period.

Water-repellent impregnation KRYSTALLIZOL Water repellent recommended not only forconcrete protection, mineral plasters and gypsum, artificial stone on cement based, but also for mineral paints, mineral wool etc.

The water repellent concentrate KRISTALLIZOL has been tested as a material for volumetric water repellency of concrete. Test results showed thatwater-repellent impregnation provides a significant reduction in water absorption - more than 3 times!

Application Crystallisol Hydrophobizer - a direct way to increase durability and improve the performance properties of building structures. Penetration depthhydrophobic compositionthe higher the porosity of the processed material, the greater. For brick and plaster it reaches 10 mm. The pore walls and all particles of material in contact with the water repellent are enveloped in an invisible, thin water-repellent film. The treated material loses its ability to be wetted by water and absorb it capillarily.

Why do you need the water repellent CRYSTALLIZOL?

- Facade protection brick buildings from the formation of efflorescence and destruction of masonry

Salt formations, or efflorescence on the walls of brick buildings, are familiar to almost all owners country houses. No porous person is immune from them. wall material, for installation of which was used cement-sand mortar. The facial area is especially affected by efflorescence. ceramic brick- on its red-brown surface, salt stains look most saturated, but also plaster facades painted with water-based or acrylic paints, do not look the best:

They appear due to water-soluble chemical compounds that are either already contained in the building material or enter it during or after the construction of walls. As the water evaporates saline solutions crystallize, and alkaline ones react with air components (primarily carbon dioxide) and form various salt deposits. Reasons for the appearance of unwanted chemical compounds There are several in the wall masonry. For example, for the production of bricks, raw materials may be used that are not sufficiently purified from impurities or contain special components that allow, say, to reduce the firing temperature. In addition, masonry mortar is often prepared in violation of technology or from low-quality cement, contaminated sand or water saturated with salts. Another reason for the appearance of unwanted chemical compounds is antifreeze additives. They are added to the cement mortar if the house is being built in winter.

Efflorescence on the facade - a problem, not only of an aesthetic nature. As they grow, salt crystals can simply destroy the walls. The appearance of a whitish coating indicates a serious disease of the facades, for the treatment of which special means will be needed, for example - efflorescence cleaner Deoxyl -2

To prevent the appearance of efflorescence, the façade must be treated with the hydrophobizing (water-repellent) composition KRISTALLIZOL; it penetrates into the material to a depth of 2÷10 mm and creates a water-repellent, vapor-permeable layer.

Water repellent for bricks - This best protection facade from the formation of efflorescence!

Treatment hydrophobic liquid necessary to ensure that water from slanting rains, wet snow, etc. does not penetrate inside the walls or other elements of buildings. It is the water that evaporates that brings the salt back to the surface.

- Protection of plaster facades of buildings from destruction as a result of moisture and frost damage to the plaster

Water repellent for plastered and painted facades protects the decorative coating of the facade from destruction and prevents peeling paint coatings on the facade. After treatment with the water repellent KRISTALLIZOL, the frost resistance of the treated material increases several times, and its strength increases by 24-26%. This is especially valuable for brick fences and pillars, plaster facades, as well as the plinths of buildings, which are most susceptible to destruction from water and frost.

- Protection of paving slabs and plinth cladding from damage and destruction

The most active destruction processes occur with paving slabs and cladding of building plinths. The greatest damage occurs on the surface of the tile in spring period when the snow melts from the sun during the day and the tiles “swell.” At night, frozen water expands and the material is destroyed from the inside.Water repellent for tiles stops the negative processes of its destruction. Covering the top of the tileshydrophobic liquid, you will increase its service life several times!

- Protection of decorative masonry from efflorescence and the formation of microcracks

Decorative masonry and the lining of the plinths also needs hydrophobic protection, because It is the basement part of buildings that is most susceptible to excessive moisture and premature destruction.Water repellent for stone will not allow moisture to penetrate inside the masonry and prevent its destruction.

Water-repellent impregnation surface of the stone significantly increases the service life of the cladding.

- Protection tiled roof And external walls from damage by fungus, moss and mold

It makes sense to coat the tiled or slate roofs, especially with a small slope. The fact is that due to good moisture absorption, mosses and lichens often begin to grow on these roofs; this, at a minimum, does not improve the appearance of the roof, and, in the worst case, leads to premature deterioration and loss of strength of the roofing covering.

- Protection interior walls premises with high humidity from mold formation

The water repellent KRISTALLIZOL is also applicable in rooms with high humidity: baths, saunas, swimming pools. Coating the internal walls with a water-repellent agent prevents condensing moisture from penetrating deep into the wall structure and forming on the surface. favorable environment for development harmful microorganisms. Besides,water repellenthas an antifungal effect. The fungus no longer appears on the treated surface.

- Protection of the walls of historical buildings covered lime whitewash and water-based paints

Facades painted with lime can be treated with a water-repellent liquid. The white lime on the façade is beautiful, but it is short-lived and is washed away by rain. If you cover lime with a water-repellent liquid, it will not be afraid of water. Dirt won't settle on it either. The result is a cheap, durable and dazzling white facade paint.

For facades and plinths of historical buildings, among necessary complex measures to save them from their further destruction, also the most important measure is the impregnation of the surface of the walls with a water-repellent composition, which will strengthen the surface of the walls and prevent their damage as a result of cyclic destruction when the wall structure gets wet and its damage (ruptures, microcracks, shedding of plaster, etc. .p.) in winter due to the expansion of moisture inside the wall structure.

In addition to the above, the water-repellent liquid is used as a water-repellent liquid for concrete, plaster, foam concrete, and limestone. In combination with water-repellent properties, it is also a primer for any facade paints, including on water based. The use of a water-repellent liquid in this capacity reduces paint consumption by approximately half, and its service life increases three to six times.

Advantages of the water repellent KRISTALLIZOL:

- Easy to use

- Cost-effective- The water repellent concentrate is diluted with water in a ratio of 1:30 and, at a consumption rate of 200 g of solution per 1 sq.m., 1 liter of the water repellent KRISTALLIZOL can be treated with 155 sq. m. m of brick wall!!

Whereinthe cost of processing will be only 12.5 rubles. per sq.m!

None of the manufacturers of similar products will offer you such economical protection against moisture!

- does not interfere with vapor permeability facades and does not change the appearance of the treated surface.

- does not create a visible, sticky film on the surface, accumulating dust

- guaranteed durability hydrophobic effect

- fire and explosion safety, absence of solvents in the impregnation composition

- absolute environmental safety

Rules for using the water repellent KRISTALLIZOL:

The water repellent KRISTALLIZOL (concentrate) is diluted with water in a ratio of 1:30, mixed thoroughly, and then applied to a dry and clean surface.

If the surface is contaminated with efflorescence, mold, affected by fungus, has a loose surface layer, etc., before hydrophobization, the surface should be cleaned with special chemical solutions to remove efflorescence and antiseptics to remove mold. For example, for cleaning limescale efflorescence and cement contamination, as well as iron salts and hydroxides can be usedcleaning composition Deoxyl-2 , remove loose plaster mechanically, wash off contaminated surfaces with water under pressure.

On the facades of brick buildingswater repellentApply a generous and even layer over the entire surface of the masonry (previously cleaned of dirt and efflorescence) in one layer until a slightly noticeable sheen of the liquid appears. On masonry and concrete structures with high porosity, the solution can be applied in two steps, with an interval of no more than 10-15 minutes. It is recommended to treat walls in dry weather at a temperature not lower than +5ºС, otherwise the hydrophobic effect is reduced.

The base must be completely saturated with a water-repellent agent, therefore required amount emulsions are calculated based on the porosity of the wall material

The effectiveness and service life of the water repellent largely depends on how well the drainage and roof covering. Unorganized flows of rain and melt water significantly reduce the duration of action of water-repellent impregnation.

If you usehydrophobizing impregnation KRISTALLIZOL and carry out all work on hydrophobization, in accordance with our recommendations, the facade of your building and others building construction and the materials will remain water-repellent for 10-12 years.Hydrophobizing impregnation It also acts as a kind of antiseptic - fungi and mold, without a nutrient medium on the dry surface of the wall, cannot actively develop.

The construction of houses and other real estate is carried out in many cities, regardless of the number of people living in it. Despite the fact that new, unique Construction Materials, used for the construction of structures, preference is still given classic options bricks

And large ones construction companies, And ordinary people We purchase bricks only from trusted suppliers. After all, we should not forget that we are talking, first of all, about the safety and reliability of the future structure. The strength of the structures being built has been tested by time. However, there are still points that can result in problems of various sizes with brickwork. To avoid the occurrence of such a situation, a number of preventive measures should be carried out in a timely manner to eliminate such a defect.

Brickwork needs to be treated by special means using hydrophobic composition for bricks, which will prevent moisture from entering directly into joints and seams. It would seem that minor exposure to moisture can lead to serious problems: cracks in the wall, loss of thermal insulation properties, the appearance of mold and other fungi.

protection of masonry - example of plaster

Even if a decision is made to insulate the walls indoors, this will not solve the problem. Under the influence of natural precipitation Negative influence moisture will continue the destructive process of the structure. It is possible to protect brickwork if adequate measures are taken in a timely manner, identifying the first signs of the presence of destruction.

Moisture protection

Protecting brickwork from moisture must be carried out until the moment when destruction becomes obvious. It would be perfect option. But, if time and precipitation have already taken their toll, then repairs can be done in several ways.

At the same time, we should not forget that even after taking such measures to protect the brickwork from the destructive effects of moisture, the surface must be inspected and cleaned at certain intervals. Such inspections should be carried out at least once a year. Everything depends on climatic conditions. Visual inspection will allow you to identify existing contamination, the presence of mold, greenery, fungus.

If the listed negative effects are detected, you need to clean the wall surface. Moreover, it is advisable to carry out this activity manually. If your financial capabilities allow, you can purchase a special device that, under high pressure, can clean the surface of any type of contamination. Once you invest money in such a device, you can use it around the house to clean surfaces, both from chemical and mechanical contaminants.
We offer you to view the features of brick processing for protection from moisture:

Sealing seams

Having identified problem areas, it is important to clean the seams between the bricks. All crumbling elements are removed. If the facing brick has lost its original appearance and strength, then it should also be removed from the wall. Next, the brick is treated to remove moisture and the joints are sealed with cement-sand mortar. After final drying, the wall is re-impregnated with a water-repellent agent.

Many people have a question - how to treat bricks from destruction. There is a special impregnation for brickwork, which seems to envelop the surface with a kind of film, preventing the penetration of moisture. The main thing is not to treat each individual seam, but the entire surface of the wall.

When starting to treat external walls, you should make sure that everything necessary materials were at your disposal. It’s better to choose a warm sunny day. This will guarantee that a dry wall will be processed, and the applied solution will quickly absorb and create the desired effect.

I would like to emphasize that moisture impregnation for bricks consists of a number of components that help close pores and cement mortar, and, in fact, in brick. As a result, it forms on the wall transparencies, which is completely invisible. At the same time, it reliably protects the wall from moisture penetration.

Any solution can be applied in a convenient way. Many people use a sprayer, while others use a roller or brush. For application, you can purchase both domestic and foreign manufacturer. A common feature Such products are environmentally friendly and safe.

Salt protection

The brick product is based on components containing only natural raw materials - clay. After a certain period of time, peculiar stains - efflorescence - may appear on the surface of the brick. The solution contains a small amount of salts. Of course, white stains significantly spoil the appearance of the wall. But this fact is not the worst thing yet. The presence of a coating of salt on the surface indicates that the process of destruction of both the wall and the mortar is slowly but surely taking place.

To eliminate defects such as efflorescence, special preparations are used. However, before you start applying the product, you must preparatory activities. The condition of the roof is carefully checked, if necessary, a new waterproofing material is installed, and drains are improved. These preventive measures will reduce the ingress of moisture onto the wall.

Efflorescence is quite often one of the first signs of the beginning of the destruction of brickwork.. With the first appearance of a specific white plaque you should be extremely careful and vigilant, since cracks, mold, and greenery may appear in the near future.

Don’t be at a loss as to how to treat the brick against destruction. By far the most effective means Water repellents protect masonry from moisture and other liquids. This is a special composition of silicon-based components. It is used at many stages of construction to achieve a water-repellent effect. They are processed and fake diamond, and brick, and ceramic tiles, even concrete, slate, cinder block, plaster, etc.

Brickwork protection water repellent increases frost resistance not only individual elements, but also the entire structure. In addition, it helps to improve the indicator of such properties as strength. Quite often this product is used in the process of wall cladding, where a high level of humidity is expected. This prevents the penetration of moisture into the material, which in turn prevents the development of microorganisms and fungi.

You can also use a water repellent when painting walls. This tandem reduces paint consumption significantly, which provides an opportunity to save a little. To work with such a substance, it does not matter at all whether you have experience or special equipment.

Main advantages of water repellent:

creating a surface where dust, dirt, etc. do not accumulate;
environmentally friendly;
fireproof;
the appearance of the treated surface does not change;
has a low cost;
durable.

The product is sold in concentrated form and diluted with water. So, 1 liter of product can treat at least 150 square meters of any surface. It is important to properly dilute the working solution. The surface to be treated must be clean and dry. It is better to pre-treat the wall antiseptics to disinfect the surface.

In order to work with such products, no special skills are required, since ease of use is another advantage of the water repellent. Unlike foreign analogues, domestic concentrate is consumed significantly less, since even in the presence of humidity, additional costs for surface treatment are not required.

Impregnation for brick walls applied thin layer. If the need arises, a short interval of 10-15 minutes should be maintained before the next layer. The validity period of the product can vary from 10 to 12 years. Throughout its entire service life, the wall will be reliably protected from harmful mold and other fungal growths. After treatment, the wall does not change its appearance at all.
We offer you to watch a video on protecting bricks from efflorescence:

Wind protection

Causes of destruction of brickwork may be different. Wind is one of those atmospheric phenomena that have a negative impact on cement-sand mortar, destroying it. Weathering concrete mixture does not happen in one moment.

High-rise buildings especially suffer from the effects of winds, where, in addition to constant air flows, there is also overheating of the external walls on the top floors. Changes temperature regime significantly affect the number of freeze-thaw cycles of brickwork. Since destruction begins precisely from the seams, when planning the construction of a structure it is important to select a cement-sand mortar with a high frost resistance. The result of the painstaking work of winds and rains after a certain period of time leads to partial or complete destruction of the masonry. Possible ones are listed at the link.

If the masonry is made with loose seams, then the frost resistance indicator decreases significantly. In addition, if poor quality brick is used during construction, then such construction is generally doomed to failure. However, even such a building can be given a second life by treating the walls with a water repellent.

Of course, brickwork should not be allowed to reach this state.

Protecting bricks from destruction carried out at the first detection of damage.

To carry out all stages repair work You should stock up on the necessary tools and materials, namely:

container for mixing the solution;
water hose;
antiseptics;
roller;
sprayer;
Master OK;
hydrophobic solution;
stairs, etc.

After reading the materials in our article, the question “how to protect a brick from destruction” should not arise. Moreover, there are many videos that show in detail each stage of repair activities.

Protecting bricks from moisture- the primary task of any builder. The better the protection of the masonry, the longer the structure will last. All types of destructive factors caused by natural precipitation are called destruction of brickwork. This is a common name among professional building contractors.
If you still have questions, we recommend watching the video instructions on how to protect a brick wall from wind and steam:

Cleaning a brick wall

As advised, walls should be subject to annual inspection, and any damage detected should be repaired immediately. Dirt and plants growing on the walls can be easily removed using a high-pressure cleaner. The home owner really needs such a not so expensive and multifunctional machine. In addition, it is suitable for washing vehicles and removing old paint. If contaminants are difficult to remove, then use mechanical cleaning or use a special paste. It is applied with a brush. After half an hour, it is washed off with the dissolved dirt.

Causes of moisture

Cracking masonry joints are a pathway for moisture to enter the wall. Water, at low temperatures turned into ice, destroys the wall. Greenery on a brick wall is a clear sign that the wall has been damp for a long time. Here, immediate help is needed for the already thoroughly collapsing wall.

Moisture can penetrate the walls due to poor-quality masonry seams or panel joints. This is confirmed by obvious stains, the formation of fungal mold inside the house, damage to the seams visible from the outside and greenery on them. There are two options for repairing such facades - if the seams are basically in order, then the masonry is made hydrophobic, that is, it is impregnated with an appropriate agent. If the seams are in poor condition, they must first be repaired.

Impregnation of brickwork

Even walls soaked in moisture should be treated with a hydrophobic compound. But it is better to do this a few days after dry and warm weather appears. The purpose of this treatment is to close the pores in the mortar of joints and bricks. The porosity of materials facilitates deep penetration of the product into them. It creates a colorless, durable, water-repellent and non-wetting film on the wall surface. Pre-impregnation is done before sealing the seams. You can use a garden sprayer to apply it. On a wall saturated with moisture, the impregnating agent is applied from top to bottom. This way it displaces water from small cracks.

In the West, they mainly recommend using Funcosil (the domestic drug “Siloxil”), which can be used specifically on damp walls. The product does not contain solvents and is therefore environmentally friendly. But when treating walls, it is recommended to cover nearby plants with film.

Preliminary sealing of brickwork joints

This is better called repair of seams and masonry, since the crumbling mortar is removed and a new filling is created in them. At the same time, individual collapsing materials are also removed. facing bricks. First, the seams are tightly filled with cement-sand mortar, then they begin sealing with a special mortar. It is better to seal with mixtures such as Betonite, Ceresite, Atlas. You can prepare it yourself using cement. It is recommended not to seal each seam separately, but to apply and rub the solution immediately onto a large surface.

So, the stages of work:

The wall is cleaned, the crumbling mortar of the seams is removed;

Individual crumbling bricks change;

Preliminary impregnation of the wall is done;

She is allowed to dry;

The seams are sealed;

The wall is cleaned and soaked again.

At least a day is needed to stabilize the preliminary impregnation. After this, the seams are sealed with mortar. For the initial sealing of joints, a cement-sand mortar is prepared, for this purpose sand up to 2 mm is used. For final sealing, a board with sponge rubber is used, with which the solution is rubbed. Using diagonal movements along the seams, the sponges remove the solution from the surface before it sets. Rinse the second time with clean water, removing traces of the solution. Sealed seams must be protected from direct sunlight. The second impregnation is carried out after 3 days.

Alternative to branded impregnation

The recommended impregnation is not available everywhere. But there is an alternative option - you can use natural drying oil or vegetable oil for these purposes. They are applied to the wall in a heated form with a brush also 2 times. But pre-impregnation requires several days to dry.

Thus, you have learned how to protect against moisture. We hope that the following tips will be useful to you. The main thing is to strictly follow them and then everything will work out!
