Impregnation for brickwork. How to decorate a room no worse than a professional designer? Brick wall in the interior as a great solution for any room

At present, such an industry is developing at a rapid pace in Russia. National economy like construction. Hundreds of different buildings and structures are erected every day. The main building material used for this is brick. Very often, private owners have problems with bricklaying. This is manifested in the fact that brick structures begin to collapse. This occurs mainly as a result of moisture getting between bricks, in joints or seams. At the same time, moisture is deposited, and in winter time and freezes, destroying the structure from the inside. Externally, such a process is manifested by the following signs: visible cracks on the walls, between the seams, a decrease in the heat-shielding properties of building envelopes, the presence of moldy fungi, greenery, and so on.

It is necessary to protect the brickwork and eliminate the negative effects of moisture on the brick.

Some owners, seeing this, begin to insulate their homes from the inside, but this does not solve the main problem. The structure gradually collapses and becomes less durable. As a result, you will have to resort to expensive repairs. It is best to prevent these negative effects of moisture on the brick. Let us consider in more detail how and with the help of what protection against moisture is carried out, the main reasons how brick is protected.

Masonry repair options

Protection of a brick wall from moisture includes hydrophobic impregnation of the wall and surface cleaning.

Protection brickwork from water is a rather serious problem. It is best to do this at the construction stage, when the damaging factor is not yet in effect. But if there is already visible signs destruction and exposure to moisture, that is, 2 main repair options. First, if the seams are in normal condition. In this case, hydrophobic impregnation of the wall is applied, as a result of which water and other liquid substances do not act on it. In the second case, the seams are first sealed, and only then water-repellent substances are used. Protecting a brick wall from moisture should include periodic inspections and surface cleaning.

Inspection is carried out at least once a year. At the same time, visible pollution is removed, greenery, mold are removed. It doesn't have to be done manually. There are special devices, for example, a cleaner high pressure. This very useful device in the household is able to clean any surface from chemical and mechanical contaminants. It can be used to clean cars, remove old paint. In the event that the dirt is not removed, a special paste can be used.

Sealing joints between bricks

Protection is also carried out by cleaning the seams between them. In the course of work, the crumbling elements of the mortar between the bricks are removed. Facing stones, which are in unsatisfactory condition, are also removed. The seams are filling cement-sand mortar, after which they are sealed with a special substance. For these purposes, it is recommended to use the following solutions: Atlas, Betonit and others. It is best to apply the solution not separately to each seam, but to the entire surface to give it greater stability and strength.

The stages of work include: removing the destroyed mortar and bricks, pre-impregnating the wall, waiting for it to dry, then sealing the seams, cleaning it and impregnating it a second time.

To seal the seams, it is necessary to prepare a mixture based on cement and sand. The solution is rubbed into the wall using a special board with rubber. Then wash the wall clean water. It is important that after this stage the surface is protected from direct sunlight. After 2 days, the impregnation is repeated.

Impregnation of a brick wall

After impregnation of the wall with hydrophobic substances, a protective film is created that does not collapse for a long time.

Protection of brickwork can be carried out in other ways. Even if the walls are saturated with moisture, it is recommended to impregnate them with hydrophobic substances. It is advisable to do this in dry, warm weather so that the solution is well absorbed. The essence of this method lies in the fact that the substance that is part of the preparation contributes to the closure of pores in the building material (in the seams and the stone itself). At the same time, an invisible, transparent, thin protective film is created on the surface of the structure, which does not collapse for a long time. Impregnation is best done before grouting. For convenience, use a sprayer.

The drug is applied from top to bottom. Previously, the domestic drug Siloxil was widely used, but its European analogue Funcosil is currently very popular. They are very easy to use, as they are very active even on wet surfaces. It is environmentally friendly, therefore it is practically safe for the human body. Despite all its advantages, the substance will not last long. Periodically, it will be necessary to repeat this procedure in order to avoid repeated destruction of the brick.

Efflorescence on the brick surface

Efflorescence on the surface of the brick indicates an active process of destruction of the wall.

Brick is a ceramic product that does not contain any salts. Even if there is a dye (metal oxides) on its surface, then salts cannot reach the surface with water. The salts give it its color. In the white brick, they are not at all. Salt is formed from a solution that is used in masonry. The composition of this stone has many pores that absorb both moisture and salt. After evaporation of water on the surface, you can see a white coating, this is efflorescence. To a greater extent, this worsens appearance designs, but it is not the main problem. The salts testify to the active process of destruction of the wall.

To remove efflorescence, the most commonly used drug is called Decap' sols Guard. Before applying it will require some preparatory work: check the quality of waterproofing, especially roofs and gutters and reduce the ingress of moisture. In addition, you will need to clean the seams. There are other similar active substances, but they have the same mechanism of action. Some of them do not require neutralization.

Water repellent Crystallisol

Water repellent Crystallisol is very economical and easy to use.

Protection of brickwork from liquid can be carried out using special substances. The most effective of them are water repellents. What is it? This is a tool that is used for water-repellent impregnation with various construction work. It is a silicon-based concentrate. It is a perfect and multi-component preparation. Experts recommend it for processing artificial stone, concrete, brick, ceramic tiles. Unlike its other competitors, it is active against wet surfaces of structures, which gives it wider use and greater efficiency.

A similar concentrate has found wide application in the processing of slate, brick, concrete, shell rock, cinder blocks, gypsum, plaster and other materials. Its scope is very large. Its advantage is that even in the presence of moisture, it is very economical, unlike its foreign counterparts. It is diluted about 30 times, so one liter of the substance is enough to process more than 150 meters of the surface of any material. The cost of processing 1 sq. meters is only 12.5 rubles. Therefore, Crystallisol is practically indispensable in this field.

Mechanism of action of Crystallisol

Crystallisol prevents the deposition of dirt, moldy fungi and the penetration of moisture deep into the coating.

Protection of brickwork in this way lies in the fact that the water repellent helps to increase frost resistance brick construction several times, in addition, its strength increases by 24 - 26%. Very often, the product is used in the lining of surfaces of buildings with high humidity: baths, saunas. In this case, Crystallisol prevents the penetration of moisture into the coating, prevents the deposition on the surface of harmful microorganisms, in particular microscopic moldy fungi. They can handle facades. Crystallisol prevents the deposition of dirt on the surface of the brick, which has a positive effect on the aesthetic characteristics of the building or structure.

Along with these useful properties, the product is widely used for painting walls along with conventional colorants. Thanks to him, it is possible to reduce the amount of paint consumed and save a little. Another great advantage lies in the ease of use. This does not require special knowledge and skills, equipment.

The advantages of this method of protecting structures from moisture

Advantages of Crystallisol: the drug is environmentally friendly, fireproof, durable, does not change the appearance of the surface.

As mentioned above, this method is very simple, efficient and economical. It has a number of advantages over other means of protection. Firstly, the water repellent does not create a visible, sticky film on the wall surface, which would cause the accumulation of dust and dirt. Secondly, this drug is environmentally friendly. This suggests that it does not contain harmful chemicals that are dangerous to humans. Thirdly, it is fireproof, unlike ordinary paint. Fourthly, it does not change the appearance of the treated surface and does not violate the vapor permeability of facades. Fifth, it is cheap. Sixth, durable.

The composition of the impregnation does not contain solvents that can be toxic. It is economical, that is, it is used only in diluted form. Its ratio to water when diluted is 1:30. Consumption rate per 1 sq. m is 200 g of solution. Thus, one liter of the drug can process more than 150 square meters. meters of surface. It is also important that it is active on almost any surface, be it brick or concrete.

Instructions for use

To protect the brickwork from moisture, it is necessary to prepare a working solution.

Protection of masonry requires knowledge of the description of the preparation, scope, preparation of the working solution. In order to prevent exposure to moisture, you will need to make a working solution. For this, the substance is diluted in ordinary water in a ratio of 1: 30, after which the resulting mixture is applied in an even layer to the surface of the brickwork. It is important that it is clean and dry. If it is contaminated with efflorescence, fungi, greens, then you first need to clean it. For this, it is best to use chemical solutions and antiseptics, which have a disinfecting effect and remove biological agents from the surface. It is advisable to remove mechanical impurities with a jet of water.

For facades brick buildings The water repellent is applied in a thin, even layer. There must be only one layer. On the concrete pavements it is possible to apply a double layer, while the interval between them is at least 10 - 15 minutes. Processing is recommended to be done in dry, warm weather at a temperature of at least + 5 degrees, otherwise the moisture protection effect may be lower. By following the instructions and proper care behind the surface of the brickwork, the duration of the drug Crystallisol will be from 10 to 12 years. This substance is also an excellent antiseptic that prevents the formation of harmful mold on the surface of the masonry.

On the facades of brick buildings, the water repellent Kristalizol is applied in a thin, even layer.

It can be concluded that very often in private construction there is a destruction of structures, including brick ones. The main reason is exposure to moisture and lack of pre-treatment surfaces with protective preparations. Moisture penetrates into the seams and pores of the brick, gradually destroying them. There are 2 main repair methods. In the first case, preliminary cleaning and removal of damaged material is required, then impregnation. In the second, the walls are simply treated with active substances. In order to make repairs, you will need equipment and tools:

• Master OK;
• falcon;
• sledgehammer;
• cement-sand mixture;
• scapula;
• ladder;
• hydrophobic solution;
• hammer;
• solution container;
• wooden stick for even application of the product;
• hose with water;
• antiseptics;
• sprayer.

Very popular today are water repellents that are able to form on the surface of brickwork protective film. It is simple, economical and very effective method moisture protection. When carrying out all work, it is very important to follow the instructions for its use. Very great importance it also has whether you noticed the first signs of destruction in time or not. Very often, the first symptoms of masonry destruction are the appearance of efflorescence on the surface, which are white coating. In addition, mold, greenery, or cracks may appear.

Protecting bricks from moisture is one of the very milestones works in the construction of a residential building using this building material. Brickwork only in appearance seems impregnable for moisture. In fact, it can seep through poorly sealed seams, window and doorways. In addition, the building material itself and the mortar used in construction absorb moisture. So that the liquid does not undermine the authority brick house, its walls are covered with waterproofing material, drainage grooves are made.

Why brick cracks or darkens

Thousands of different buildings and structures are being built every day in our world. One of the most common building materials is brick.

It often happens that many people who have used this material have problems over time. These problems consist in the fact that the brick begins to collapse after a certain period of time. main reason This phenomenon is the ingress of moisture into the brick itself, as well as between them, into the joints or seams. Moisture is absorbed into the structure, and in the winter it freezes, destroying the brick from the inside.

Cracks appear on the walls, between the seams, decreases thermal insulation properties, often a fungus appears or the brick begins to turn green. Required in as soon as possible figure out how to protect the brickwork and eliminate the harmful effects of moisture on it.

Some people think that in order to stop the destruction, you need to insulate the walls from the inside, but this is not so, this will not help solve the current problem. And the more you delay, the more deplorable the state of your brick building will become, the structure will begin to collapse over time, as a result, it will not be possible to do without expensive repairs.

In this article, we will consider in more detail how and with what preparations it is possible to protect a brick wall from negative impact moisture and identify the main causes of brick destruction.

Impregnation of a brick wall

Protecting bricks from moisture - applying the mortar to the masonry

An invisible, transparent film is created on the surface of the wall, which will protect your brick from harmful influences and factors, the same feature of this film is that it does not collapse for a long time, which will allow you not to return to this process for a long time.

Also, the protection of bricks with a water repellent agent helps to increase frost resistance and increases its strength by about 30%.

As already mentioned above, this method very easy to use, and incredibly effective. The drug has many advantages over other protective agents:

Protecting bricks from moisture - windows

Around window openings hydrophobization is carried out even more carefully. To seal openings, ebbs and gaskets made of composite materials are used. waterproofing materials. Such materials are made on the basis of bitumen or fiberglass. Strict requirements are imposed on the used ebbs.

They are made of metal, with a curved back wall and a shaped teardrop. Also, the ebbs are given a deepened shape in the middle. Otherwise, water will seep past the window openings and the frame.

Protecting bricks from moisture - window sills

It is difficult to ensure that the tides adjoin the building frame tightly, but it is possible if the contact point is closed with special overlays from the correct waterproofing agent. Windows and doors are raised above the waterproofing of the base so that moisture does not reach them and spoil the structure.

Use instead of drains roll waterproofing unreasonable. Because the service life of the metal is many times greater than the shelf life of waterproofing materials. back wall ebb nailed to the skin on 5-10 cm above its horizontal shelf. If you do not do this or make a mistake in the distance, then water will penetrate into the wall through holes for self-tapping screws.

It is necessary to make sure that the horizontal shelf of the ebb ends with a teardrop. Without it, the liquid will flow back into the wall cavity. To remove harmful liquid from under the cladding means to make drainage grooves next to the ebbs. They are also equipped above windows and doorways.

Spectacular drainage channel are sheer seams between bricks of the same row. So that drops of moisture, driven by the wind, do not penetrate inside the walls, the channels are made round. First, oiled rods are placed in the solution, which are removed after the solution has hardened. The resulting holes are perfectly suited to their purpose. On them, moisture quickly and irrevocably leaves the brick cladding.

The same effect is obtained when using plastic tubes. Install two rows of tubes in case the first one is filled up construction waste or solution. Often the seams are not completely filled with mortar, because it is difficult to do this in bonded seams. But because of this, moisture will very quickly find its way inside the walls. Therefore, make sure that the seams are completely filled, and parts of the solution do not fall into the drainage channels.

Foundation protection

It is also necessary to take care of the foundation, because it bears a huge load from the structure, and also add the harmful effects of moisture and dampness. This is best seen in autumn or winter period after the rains. Moisture is absorbed into the foundation, as well as the lower layer of brickwork, at low air temperatures it freezes, causing irreparable damage to the brick, which will eventually begin to collapse.

To such unpleasant moments exclude buildings equipped with metal or plastic drips, which are installed on the basement of the building. Ebb tides cover the entire building, without interruption in any place. They cover both internal and external corners.

protection of bricks from moisture - foundation

Of course, it is better to entrust all these works to professionals who will reliably, quickly and efficiently do all the work necessary to protect the brick wall.

However, if the financial component does not allow this, and you have at least some building skills, you can do all these works yourself, and believe that the quality of the work you have done will not be worse, you just need to try.

The destruction of the brickwork of the walls of red and silicate brick occurs under the influence of environmental factors. To delay and even prevent the destruction of bricks, we recommend paying attention to the material Monolith-20M-K is a lithium-based impregnation designed specifically for the protection of masonry, gypsum plaster, decorative terracotta products, as well as buildings built from sandstone, limestone and natural stone materials. The most strengthening properties of the surface are achieved by impregnation treatment. Monolith-20M-K old brickwork.

Technical characteristics of impregnation

Not in all neutral structures building materials, active oxides are formed, capable of forming crystalline compounds that strengthen the internal structure of the compound, under the influence of chemical compounds. Monolith-20M-K It has distinguishing feature impregnation structures that form non-hygroscopic ceramic structures using AquaCeramic technology. This property distinguishes the ceramic structure created Monolith-20M-K, from the main structural component of red brick - bauxite, which constantly absorbs moisture from the environment, even in arid regions.

Insoluble ceramic structures, formed by penetrating up to 40 mm deep into the smallest pores of the processed material, create strong walls inside the pores, consisting of crystals. microcracks in the brick blocks, sandstone and other building materials, after impregnation treatment Monolith-20M-K“overgrown” with a ceramic structure that increases impact resistance, toughness and wear resistance of surfaces.

In addition to moisture, sulfates and chlorides penetrate into the brick structure, under the influence of which, the destruction of brickwork occurs more rapidly. This fact can be observed in the structures damp cellars, where brick crumbling occurs at a slight force pressure. Monolith-20M-K isolates microscopic compound granules from the environmental impact of atmospheric phenomena, increasing the resistance of the surface to physical and biological damage several times.

Surfaces treated with impregnation Monolith-20M-K, harden, acquire the properties of water resistance, "breathe", but do not form dusting. At the same time, all previous properties, including gas permeability, are preserved, excluding moisture penetration.

Features of the use of impregnation

Monolith-20M-K most suitable for reinforcing dilapidated surfaces of brick and marble masonry, as well as surfaces made using natural natural stone all kinds. The protective functions of impregnation are also used to prevent damage, visible and hidden cracking.

Completely preventing the penetration of moisture into the treated surface, the impregnation significantly reduces the consumption of thermal energy, even when applied to the surface of the wall panels of residential buildings.

Properties and benefits.

Surface treated with impregnation Monolith-20M-K, acquires the property of short-term resistance to inorganic acids.

Long-term resistance to the influence of most organic acids, fat-containing mixtures and petroleum products of various origins is an indisputable advantage of the treated surface.

Terminating dusting of the surface, forms an increased abrasive resistance.

facade paints and epoxy coatings applied on top Monolith-20M-K, acquire improved properties during adhesion to the base coat.

The transformation of free lime, which is part of building materials, occurs in water-resistant flint - a shaped, wear-resistant part of the structure of a building material.

Instructions for use.

Ambient temperature creating optimal conditions for high-quality impregnation of brick or stone surfaces Monolith-20M-K, should be within temperature regime, from +10 to +30 gr.С. Humidity, previously cleaned surface, should not exceed 5-10%. The loose surface must first be cleaned of collapsing particles. If cracks and shrapnel damage are found, pre-hide with mortar.

All work with impregnation must be carried out, protecting hands with rubber gloves and using goggles, since the liquid is alkaline, but not combustible, and on water based. At the same time, volatile organic compounds- absent in the composition of the impregnation.

The area required for processing must be prepared in accordance with the possibilities of continuous processing, taking into account rapid drying in the presence of draft, wind, high temperature environment. The recommended area for one treatment cycle can be from 50 to 150 sq.m.

A continuous application process, either by brush or spray, treats the surface without allowing excess impregnation to accumulate. That is why the use of a roller is not recommended. Repeat the surface treatment with a 3-fold repetition process. At the same time, avoiding excessive accumulation of impregnation. The layer must be sufficiently thin and continuous.

Depending on the porosity and damage of the brickwork, the absorption time of the applied impregnation can vary up to 10 minutes. After the disappearance of the gloss of the previous impregnation coating layer and complete absorption, it is necessary to apply the next layer. At the same time, taking into account the consumption rate liquid material in a volume of 0.25 liters to 0.65 liters per sq. meter.

Aged or extremely damaged brick or stone surface can be treated up to 5 times, while repeating the treatment after 2-3 hours.

Surface treatment Monolith-20M-K it is necessary to prevent the ingress of impregnation on aluminum and glass surfaces any type. In case of contact with the skin or the above surfaces, wash off with plenty of water.

The price of impregnation for bricks

Often, after the construction of a house, typical difficulties arise - the material from which the walls are built strongly absorb moisture, as a result of frost, the surface is destroyed. This problem will help to solve a water repellent for bricks. This is one of the options for processing building materials that can increase the degree of frost resistance, water resistance and improve the thermodynamic index. In general, the product allows you to increase the operational life of building materials several times.

Water repellents first appeared on the market 40 years ago and have been actively gaining popularity in the construction industry since then. The first modifications were big amount shortcomings, including flammability, the need for regular renewal of the protective layer, short-term effect. Thanks to modern developments, new fluid modifications have long been devoid of these problems.

What is it and what is it used for

The durability of any building depends on a variety of factors, but atmospheric phenomena can be called the first “enemy”. We are talking more about moisture, drops of which penetrate the porous structure of the material, freeze when cold weather sets in, expanding in size, and gradually break it apart. From year to year, the process is repeated cyclically, and as a result, even the most durable products burst, flake off and collapse. This applies to how monolithic structures, and bricks, whose structure is too porous to neglect the protection factor.

So the brick is gradually destroyed by moisture - the process is long, but irreversible

Builders for these purposes use 2 methods:

• waterproofing;
• hydrophobization.

Despite the consonance and common goal, these methods differ from each other. Waterproofing - covering the base with a vapor and waterproof material ( mineral wool, polystyrene, etc.) or a coating with a viscous solution that completely blocks the ingress of water into the pores.

The principle of waterproofing is well described in the article "".

Hydrophobization - a sharp forced decrease in the ability of products, objects and materials to absorb moisture while maintaining air, gas and vapor permeability.

The hydrophobic solution that is coated on surfaces is not pure form water-repellent, since water drops do not repel, but, on the contrary, are weakly attracted and flow down, while the solution molecules are firmly held on the surface.

Hydrophobization: before and after

These salt solutions are based fatty acids, copper, aluminum and zirconium molecules, surfactants, potassium alkyl siliconates, silicon and fluorine compounds, etc. All this in the complex provides the thinnest coating that protects against getting wet.

How often do you need to process

Hydrophobic mortar for silicate bricks or any other, is available as a liquid mixture. The construction should be processed once every 10 years. This will be quite enough for the surface to retain its original appearance. Also, impregnation will protect the structure of the stone from the appearance of fungal formations and efflorescence, improving the performance properties of the building material.

The moisture-resistant mixture functions on the principle of varnish, but it can be used both for processing wood material, and for concrete blocks, ceramics, stone.

Benefits of water repellent solutions

Users leave on various forums multiple positive reviews. A water repellent for bricks is used in the process of interior work in the room, and the product, which includes organic solvent, intended for the processing of facades.

Regardless of the constituent components, the liquid does not have any characteristic odors, shades, but at the same time it has a high degree of moisture repellency. The mixture, after application, is absorbed into the structure of the building material to a depth of 20 mm, where it creates a protective shell. The layer does not allow atmospheric precipitation, condensate and other kinds of moisture to be absorbed into the building material. When rain hits the treated masonry, it simply rolls off without lingering on its surface.

Water droplets are attracted and collected into larger fragments that simply roll off the surface.

Treating bricks with mortar prevents the house from partially darkening, which protects it from deterioration of external parameters over time. Over the years, environmental factors affect the structure of a building product, bringing dust and moisture into the pores. This changes significantly technical features the building itself, the color of the walls and general form facade.

Hydrophobization can be carried out directly on wood elements. The method will not only serve as an obstacle to the darkening of the tree, but also counteracts rotting.

Also, a water-repellent liquid is intended for processing sections of the block with open steel reinforcement, since it does not provoke corrosion.

The method of processing bricks with a water repellent is distinguished by good atmospheric resistance, it prevents the deformation of building materials. With all this, the component does not lose its operational properties at elevated temperatures.

The best water repellents for bricks according to builders

Specialty stores provide a wide range of various mixtures designed to protect structures from moisture penetration. Therefore, you can buy liquid from both the budget category and the expensive one.

Water-repellent impregnation

To determine which material is better to purchase, you should study its main divisions, which differ in composition and operational features.

Siloxyl

Produced on the basis of domestic developments. protective layer created by an organosilicon compound. The main component of the product is water, the rest of the components are odorless and colorless. The composition does not contain solvents, is non-toxic and fire-resistant. Processing with the mixture is carried out using a mechanical spray, roller or large brush.

Siloxyl. Price - 100 rubles per liter + container cost

Aquasil

A modern series of products made on the basis of a silicone element, soda and water. This modification is characterized by environmental friendliness, refractory function, manufacturability and safety. Used for finishing concrete structures, ceramic blocks, wood.

Aquasil. Price - 450 rubles

Hydroshield-Super

It is used in an environment where there is a regular high humidity. The composition includes antiseptic additives that counteract the fungus. When applied, it is well distributed over the surface and plasticized.

Hydroshield-Super. Price - 1600 rubles

neomid

Universal mixture of protective purpose is applied to almost all types of building materials. Requires regular renewal every 10 years. It is used for internal works and finishing of a facade. It has a low consumption, only 1 liter of the product is required per 1 sq.m.

Ceresit

The product of the German manufacturer has the property of deep penetration up to 5 mm, which allows you to repair microcracks in the masonry itself. When applied to the primer layer, the consumption will not exceed 400 gr. per 1 sq.m.

Difficulties may arise in processing, since the solution is completely transparent - try not to skip even small areas

Among the disadvantages of processing bricks with a water repellent, the transparency of the emulsion should be highlighted. On the one hand, this is an advantage, but when it comes to surface treatment, difficulties arise, with a short stop, you can make a mistake with the area where the mixture has already been applied.

Technology for the use of silicone solutions

There are several techniques for applying the composition.

1. Surface hydrophobization

The standard way in which working surface processed with a pre-prepared solution. This can be done with a roller, brush or by spraying, this does not affect the quality. The most important thing is that the surface is completely covered and there is no “gap”.

small structural elements it is more rational to dip in liquid to achieve maximum coverage.

1. Bulk impregnation

As a rule, it is used at the stage of manufacturing building materials, but it can also include the stage of surface application already at the facility or even at the factory. If we are talking about bricks, foam or aerated concrete, then the GF is introduced into water, which is mixed with cement and sand.

1. Forced processing

Injection of a weakly concentrated substance. This method, as a rule, acts as an additional to bulk or surface impregnation.

Application rules

To obtain a high-quality protective layer, you must follow the following instructions:

• First of all, you need to clean the surface to be treated, remove all accumulations of dirt and dust.
• Eliminate microcracks and other defects.
• Prepare the mixture, transfer to a convenient container and mix until a homogeneous consistency is obtained.
• Apply the product with a roller or brush until the surface no longer absorbs the solution intensively.

The time limit of the absorption process after processing the brick with a water repellent can vary from 20 minutes to 24 hours.

VIDEO: Overview of the characteristics of bricks after treatment with a water repellent

Under the influence of external negative factors, brick walls are gradually destroyed, this entails problems that arise inside the premises. Walls near the attic and foundation are especially in need of protection, because they are constantly exposed to moisture and precipitation that pass inside.

Over time, this leads to the appearance of fungus and mold, which negatively affects human health and the condition of structures. As the main way to protect surfaces, one can single out the waterproofing of a brick wall from the outside. To do this, today there is a huge variety of materials that are worth considering in more detail.

The need for protection

Brick is a porous material, therefore, when used in wet conditions, it is saturated with moisture, and a destructive process begins inside. The structure loses its integrity over time. It is possible to protect structural elements from moisture with the help of waterproofing. These works are carried out in the basement area and external walls. That's why better waterproofing brick to supplement with internal work. A complex approach allows you to deal with destruction throughout the entire period of operation.

Depending on the type of protection chosen, the algorithm for carrying out work may be different. Outdoor waterproofing is usually carried out with welded materials, while inside the work is carried out with the help of coatings. The main feature of such work is preliminary preparation bases, which must be even and dense for a good fit of the waterproofing layer. Preparation can be carried out using lime-cement mortar based plaster. However, ready mixes can also be used.

penetrating compounds

Among professionals, penetrating waterproofing is quite common, which gives structures additional properties. When finishing the wall, modifiers are added to the solution, which penetrate the material through the capillaries.

Among the advantages of such a waterproofing of a brick wall from the outside, it is worth highlighting:

• low cost of materials;
• the ability to protect external and internal surfaces;
• high levels of protection at the level of bitumen or film;
• a wide range of offered materials;
• maximum penetration into the structure.

To protect the masonry from capillary suction, a restoration method is used horizontal waterproofing- injection. This method is effective and widely used. For horizontal waterproofing of a brick wall by injection, holes are made in the lower part of the structure in two rows, where special composition. These jobs are ideal for materials with low viscosity and long time curing. These mixtures fill the joints of the masonry and impregnate the pores of the brick.

Looking at penetrating you can get a closer look at the composition of "Penetron". It is a dry mixture of cement, quartz sand and chemical additives. "Penetron" is used to protect monolithic and prefabricated structures. With its help, it is possible to increase the indicators of water resistance, frost resistance and strength. The structure after the completion of the work acquires the ability to undergo impacts:

• sea ​​water;
• groundwater;
• Wastewater;
• alkalis;
• acids.

Work methodology

For waterproofing, it is necessary to follow a certain algorithm. At its first stage, the surface is prepared, cleaned of the remnants of the solution and various pollution. Next, the base is treated with a primer, which fills the pores and increases the protection of the material from mold and mildew. The surface is re-wetted, which is dictated by the characteristics of the brick.

Next, you can start applying waterproofing with a spatula or brush. The solution is mixed and laid according to the instructions. The thickness of the applied layer may vary depending on the composition. At the final stage, finishing is carried out. It may involve plastering the surface, but experts argue on this topic. Some believe that waterproofing must be applied to the finished finish, otherwise condensation, fungus and mold may occur.

Coating waterproofing

Coating waterproofing of a brick wall outside involves the use of dry mixes, to which are added chemical substances. After dissolution, they form a pasty consistency. When choosing one or another composition, it is necessary to be guided by the following factors:

• ease of use;
• crack resistance;
• vapor permeability;
• water resistance;
• durability;
• practicality.

The method of carrying out work on the application of coating waterproofing

The application of any waterproofing layer provides for the need for surface preparation. It includes cleaning the base from dirt and dust, as well as restoring the seams, if necessary. The walls are covered with plaster, and then a waterproofing layer is applied with a hard brush, which allows you to get flat surface. It is smoothed out with a roller. At the final stage, finishing with facing material is carried out.

Waterproofing a brick wall outside from rain is often carried out with coating materials that have unique properties and proven quality. As an example, we can consider a product of German manufacturers, for example, Aquafin. This composition suitable for a wide range of jobs. After the application process is completed, a day must pass for the material to become solid, then facing work can be carried out. A week later, the wall is ready for water loads.

In order to exclude the appearance of cracks on the surface, a polymer-mineral waterproofing is used, which contains an elasticizer. This additive provides elasticity to the hardened layer, and in everyday life such compositions are called rubber concrete. The mixture is applied with a hard brush on a moistened surface, which makes it possible to obtain a seamless coating that bridges cracks.

The use of welded waterproofing

Waterproofing the house in the area of ​​a brick wall can be carried out. This protection involves the use of roll materials, which are attached to the base after thermal heating. The work is carried out according to the following technology: for a snug fit of the insulation, the surface is covered with plaster, and then primed bituminous mastic which guarantees reliable adhesion. The strips are cut into individual sheets of the desired length. After that, they are heated with a propane torch until bubbles appear on the material.

The insulation is glued to the surface. The strips must be attached without voids so that the material does not lag behind the wall. Therefore, the waterproofing is smoothed out with a roller or by hand during installation, and problem areas are cut out to make separate linings for them. The strips are glued with an overlap, the width of which is 10 to 15 cm. personal protection, because the work is carried out with hot material.

Use of horizontal waterproofing

Horizontal waterproofing prevents the passage of water into the structure. It is represented by a layer, which is laid on horizontal surface, and for this you can use the most different materials. Suitable for brick walls cement mortar or asphalt.

After masonry is erected to the design mark, sealing agents are added to the mixture, with the help of which a layer of mortar up to 30 mm thick is made. When using asphalt, this parameter is 20 mm, and the first row of bricks is laid just on this layer of mortar. A waterproofing layer based on rolled materials is laid on a leveled surface, and the surface of the sheet is smeared with bituminous mastic. At the next stage, you can continue laying.

Pasting waterproofing from the manufacturer "TechnoNIKOL"

Pasting waterproofing "TechnoNIKOL" is made on the basis of bitumen, which is mixed with atactic polypropylene or styrene-butadiene styrene. These additives are modified polymers, which makes the material more durable and strong.

Pasting waterproofing "TechnoNIKOL" is also created using vulcanized rubber, polyethylene and thermoplastic. The latter is made of polyvinyl chloride and chlorinated polyethylene, which are heated before use, and the seams are sealed by welding or using solvents.

The cost of roofing material and its some properties

Despite the emergence of more and more new materials for waterproofing, roofing material, the price of which remains acceptable, is still relevant. You can buy this material from the manufacturer "TechnoNIKOL" for 15.2 rubles. behind square meter. In this case, we are talking about a variety of RPP material.

It is durable, light and soft, so it has found its wide application, but does not withstand low temperatures. Because of this, residents of the northern regions quite often refuse it. But for horizontal waterproofing of a brick wall, this material is suitable, which is located between the masonry and the foundation.

Ruberoid, the price of which is acceptable compared to many others modern solutions, is made on the basis of cardboard, which is impregnated with soft petroleum bitumen. The coating is applied on both sides and sometimes supplemented with a fine-grained dressing.
