Has your once bright and festive home suddenly lost its appearance? What's the matter? The neighboring brick buildings were erected at the same time, but they stand and are pleasing to the eye, but you have strange spots white? These are efflorescences on the brick. Unfortunately, efflorescence removal at brickwork It’s a rather complicated procedure, but the sooner you take on it, the easier it will be to return your home to its former charming appearance.

What are the causes of efflorescence?

If efflorescence suddenly appears on a brick, it is recommended to find the cause of its occurrence and remove it as soon as possible. Efflorescence on facing brick may occur due to the movement of salt water through it. When a brick is heated, if there is water on it, it will slowly evaporate. At the same time, the salt will form a white coating. Most often, people think that this is just an aesthetic awkwardness, but in fact it is much more serious. Salt creates certain destruction mechanisms in the wall that act slowly but surely.

Thus, to summarize, I would like to say that the causes of efflorescence can be:

• alumina - material for making bricks;
• sand is one of the main components of the solution;
• water of natural origin that contains salts;
• natural precipitation;
• priming.

How did the salt end up inside the wall?

• First, some of the salt could be in solution. Its manifestation is provoked by antifreezes, accelerators and other additives. If salt appears, it means you overdid it with the additives.
• Secondly, salt could get in directly from the ground through the foundation. This may not say much good connection foundation and walls, or unreliable waterproofing. Alternatively, salt can also indicate a lack of drainage or its unreliable operation when the groundwater level is high.
• Thirdly, some salt could also penetrate into the wall through precipitation.

How and with what to remove efflorescence from facing bricks?

The question of how to remove efflorescence from brick should be dealt with by specialists, but if you decide to save money, then you can do all this yourself. True, special organizations would do all this at a higher level, determining the composition of efflorescence using chemical analysis, and selecting the right remedy for removal and, if possible, additional protection walls.

It is worth noting that the nature of the appearance of efflorescence is different, since they appear from different types salt. Consequently, the measures to combat them are also different. Some efflorescence can be easily removed with ordinary water, while others can only be removed with a special means for removing efflorescence on brick. But such products also differ from each other and remove salt deposits only of a certain type.

If such a situation arises, you should act experimental method, thus testing a small amount of each product and trying to clean the plaque off the brick with it. It is with this method that you will find the product you need and save time and money on chemical plaque analysis.

How to determine the amount of cleaner and apply it?

When carrying out work, you must wear special clothing, a respirator, and always gloves, since the cleaner is very harmful to humans. The efflorescence remover is diluted with water and applied in a convenient way (brush, roller). The proportion for diluting the product is usually indicated on the packaging.

The use of many building materials is accompanied by problems with their aesthetic appearance. It seems that the brick is of high quality, the mortar is prepared according to all the rules, but after a while white smudges appear on the wall! What could be the problem and how to remove efflorescence from brickwork? Let's try to understand this issue in more detail.

What are “efflorescences”?

Efflorescence is different kinds salts that appear on the surface of brick, concrete or natural stone. They are transferred aqueous solutions and crystallize upon evaporation of moisture.

The danger of this phenomenon lies not only in the fact that it spoils appearance masonry If you do not remove salt from the surface of the elements, then after a while they will begin to collapse.

Thus, the elimination of efflorescence allows preserving aesthetic appearance building, increase its service life, ensure standard parameters for the strength and thermal insulation of bricks.

Causes of salt deposits

What are the reasons for the appearance of efflorescence on brick:

• Movement of water and salts from inside the material to its front surface.
• The release of moisture when the masonry mortar dries.
• Capillary suction of water from the soil through the foundation and wall structures.
• Precipitation.
• Leaking roof and drainage system.
• The presence of hazardous industries nearby.
• Maritime climate.

When drying on the surface of the material, salts can enter into chemical reactions with other substances. Therefore, they often become insoluble in water, making them difficult to remove.

The higher the density ceramic product, the smaller the number of pores in it. Therefore, these bricks are less likely to develop salt stains.

How to avoid efflorescence on brickwork?

To do this, you must follow some rules:

• Ceramic products need to be selected good quality. If even before purchasing the material you noticed on it front side white spots, the manufacturing technology may have been violated.
• Before sale, bricks must be provided the right conditions storage Open pallets outside indoors- is not the best option for preserving ceramics. The porosity of the brick will lead to the fact that there will be high level humidity. The consequences will be efflorescence.
• The site also needs to protect building materials from moisture.
• Masonry work should be carried out in dry weather. This way the brick walls will not become waterlogged.
• Mortar is often made with the addition of a large amount of water for ease of work. But this factor can significantly affect the appearance of salt stains on the wall after the mixture has dried.
• Do not delay the construction of masonry under the roof. The longer construction takes place, the more unprotected masonry can absorb moisture from the outside.

• For the solution you need to take washed river sand– the amount of salts in it will be less.
• The water for the mixture should not be hard. If possible, you should avoid adding various plasticizing additives to the solution. This will also reduce the risk of efflorescence.
• Mandatory waterproofing of the foundation of the house is required. It will reduce the capillary suction of moisture from wall structures.
• The roof needs to be equipped reliable system drainage

Prevention possible reasons the appearance of salt deposits will cost much less than fighting them.

“General cleaning” of the masonry surface

If, despite all the preventive measures taken, white streaks still appear, then it is necessary to get rid of them as quickly as possible. The longer the salt remains on the surface of the material, the sooner it will begin the process of its destruction.

How to remove efflorescence from brickwork? It is best to use special products based on acids or alcohol. Ordinary water will not cope with water-insoluble salts of calcium, iron, aluminum, magnesium or barium.

• It is necessary to purchase a small amount of solvent to test it on a brick. Salts may be different composition, so not all products are suitable for removing them.
• After the detergent has been selected, you can begin to remove plaque from wall structures. This should be done using funds personal protection, since the solutions are unsafe for humans.
• Mechanical cleaning of salt deposits is carried out.
• Cold or hot water the wall is washed.
• To remove residual efflorescence, a cleaning agent is applied to the surface of the masonry with a roller or brush and left on it for some time. The manufacturer's instructions will tell you more accurately how long it takes for the salt deposit to completely dissolve.
• Next, you need to thoroughly rinse the walls with plenty of clean water.

How to get rid of efflorescence on brickwork using improvised means? You can prepare a suitable solution yourself. This will require water and hydrochloric acid 2 - 4% - the solution is applied to the wall and washed off with water after 10-15 minutes.

Sometimes washing away salt deposits causes new white spots to appear from inside the masonry.

• In this case, it is necessary to pre-treat the masonry with a hydrophobic composition. Penetrating inside, it will prevent the release of salt onto the surface of the masonry.
• The wall structure requires a day to dry.
• Then the efflorescence is washed off again with solutions.
• Next, the entire surface is washed with clean water.

The selection of special solutions depends on the type of salt deposits and the degree of their formation.

Protection against further efflorescence

Getting rid of existing salt deposits is only half the battle. The masonry must be reliably protected from their further appearance. On construction market V large quantities There are a variety of brick processing products available.

Water-repellent impregnations are produced for a specific type of material, but there are also universal solutions. Their prices vary significantly depending on the composition.

Hydrophobizing impregnation prevents moisture from penetrating inside the brick - photo

They form a thin film on the surface of the elements, preventing water from penetrating into the product. In addition, it is impossible to firmly attach salt deposits to such a film.

An elementary option could be a regular primer. But this will not help protect the masonry for a long time. It is better to use compounds specifically designed to reduce the water permeability of bricks. They will be in effect for several years. These products also make it possible to increase the frost resistance of masonry and improve its thermal insulation properties.

Professional solutions are made on the basis of acrylic or silicone, which penetrate inside ceramic element and effectively protect brickwork from water. Protective varnishes are also available. They not only create a durable film on the surface of the wall, but also give it a more aesthetic appearance.

Brickwork processing technology

Hydrophobizing agents do not eliminate efflorescence on masonry. Their task is to reduce the degree of water absorption of the material of wall structures. That is, before using them, it is necessary to get rid of salt stains on the brick.

• The surface of wall structures must be thoroughly dried.
• The solution is applied with a roller or brush.
• The walls are dried for 1 - 2 days.
• Then the procedure is repeated again.

Double-layer protection will be more reliable and durable.

When spending significant funds on the construction of a brick building, it is worth worrying from the very beginning about eliminating all the reasons that could lead to the appearance of efflorescence on the masonry. If they do appear, then work to eliminate them cannot be postponed.

Wall structures can not only quickly lose their attractive appearance, but also be seriously damaged specifications. More information on this topic can be found in the video in this article: “How to remove efflorescence from brickwork.”

- these are crystals of salts that came to the surface with moisture that seeped into the walls with precipitation and from the soil.

The result of salt corrosion on the facade: peeling of the front layer, whitish spots - efflorescence.

There are at least five sources for the appearance of efflorescence on the façade. The first is the salts contained in the raw material (alumina) from which bricks are made. And ceramic brick, due to its porous nature, is “prone” to absorb moisture. Penetrating from the outside, it dissolves salts, and evaporating, draws them to the surface.

The second source is masonry mortar. It contains cement, sand and water. Sand is mined in the quarry closest to the construction site; water is also taken from the nearest source, and the salt content in them is fair.

Salts are also contained in the soil on which the house is built.

The fourth source is atmospheric moisture: rain, snow, fog. More precisely, not water as such, but what it carries. If there is a chemical plant nearby, it is likely that efflorescence will soon ruin the walls of your house.

Another reason for the appearance of streaks is various additives in concrete - accelerators and retarders. Let’s say construction is carried out at an accelerated pace, or in conditions subzero temperature. Anti-frost additives are especially insidious: after them, surfaces are covered with terry white patterns.

But the stains on the surface are just the tip of the iceberg. The main problem lies deep in the pores of the brick from which the house is built or decorated. The lion's share of salts dissolved in water remains inside. And when moisture evaporates, the growing crystals rupture the pore walls, which causes cracks to form - first in the cladding, and then in the wall.

To give a normal appearance to the facade you need to:

Remove salts that appear on the surface;

Protect the surface from moisture ingress.

Non-hydrophobic masonry Hydrophobized masonry

Most often it is not possible to get rid of efflorescence using brushes and water. Water penetrates inside the wall and can, by evaporating, “pull” the next portion of salt to the surface. In addition, brushes, especially metal ones, can damage the surface layer of the brick. Therefore, special cleaners must be used to remove efflorescence.

On today's market there are already many products that remove efflorescence and mortar stains from bricks. These are materials of domestic and imported production, usually of a weak acid composition.

They dissolve the surface layer of salt without changing the natural color of the brick. It is important that the cleaners do not spoil other façade elements, windows, ebbs, drainpipes and were environmentally friendly.

As for preventing the reappearance of efflorescence, there are rules here too. First of all, it is necessary to protect the brickwork from water ingress: restore damaged roofing or waterproofing.

To protect against slanting rain, materials should be used that do not interfere with the vapor exchange of the facade, since in residential construction the vapor permeability of enclosing structures, naturally ensured by the porosity of the materials, is one of the most important sanitary and hygienic requirements for the building. Therefore, it is not advisable to use materials that create a film, such as drying oil, vapor-proof enamels, etc. It is optimal to use water-repellent liquids.

Hydrophobizers are solutions of organosilicon (silicone) compounds diluted with water or organic solvents.

The principle of operation of waterproofing liquids is that silicones, using a carrier (water or solvent), penetrate into the thickness of the material being processed (penetration depth can be up to 35 mm) and then polymerize, creating a water-repellent, vapor-permeable layer.

In general, the issues of cleaning facades from salts and preventing their reappearance should be resolved comprehensively, with the involvement of specialists. Otherwise, the use of incorrectly selected products will lead to even more efflorescence.

Our company, the SAZI Production Association, has been working in the field of development and production of materials for cleaning and protecting mineral surfaces for more than 20 years. During this time, we have gained a lot of experience, and we know that if you take timely measures to protect the facade from the aggressive effects of water, then in the future you can avoid the appearance of repeated efflorescence on the surface of the brickwork.

Brick has been and remains the most popular building material for buildings of any type. It is durable, reliable, brick house always will be warm in winter and cool summers. It would seem - perfect solution for long periods of time and any budget. But brick can also bring surprises to the owners of houses and buildings. Especially in seasons such as autumn and spring. And the most unpleasant surprise is the appearance of efflorescence on the brick.

When a white coating appears on the wall of a building, the reasons for its appearance and how to deal with it - we will now deal with you.

Reasons for the appearance of efflorescence on the wall of a house

On beautiful, red brick walls, every attentive owner will immediately notice white stains, but not everyone will attach importance to this or begin to act promptly to quickly eliminate the strange whitish pattern in the masonry. And this wave-like pattern is efflorescence and should be removed very quickly.

Efflorescence, in its essence, is ordinary salt that appears on the surface of a brick. Brick is a hard, porous sponge that perfectly absorbs moisture, and it, in turn, contains various salt impurities. At a certain temperature, salts naturally “evaporate” onto the surface of the brick, which, when dry, crystallize on the surface, forming sloppy stains. If it seems to you that the area of ​​efflorescence is insignificant, do not delude yourself and do not hope for chance. Only a small part of all the salty “wealth” contained in the building material appears on the wall.

The appearance of efflorescence is a consequence excess moisture. Salt deposits are found almost everywhere and their appearance on brick surface It doesn't depend on the person at all.

The reasons themselves are quite banal and lie almost everywhere:

• The material from which the bricks are made contains a certain amount of salts. Due to the moisture easily absorbed by brick, these chemical elements dissolve and come to the surface building material under influence high temperature during the process of liquid evaporation.
• The water that is added during the brick production process introduces its own portion of salts.
• Another recipe component in brick production that adds a fair amount of salts is sand, which contains a lot of lime. And, if it is not washed between cycles: mining in a quarry - adding to the brick batch, then the brick will obviously be fairly “over-salted”.
• The soil on which the house stands also tries to keep up with everyone and makes its salty contribution to the emergence of a salt problem.
• Natural precipitation in any form - where would we be without it? And in cases where a chemical production or enterprise is located nearby, an increased portion of salt is provided to everyone.
• Lack of conservation of masonry in the autumn-winter period, if the construction process is interrupted for any reason.

The appearance of efflorescence should not be taken as a death sentence for your building. The same as letting everything take its course. Efflorescence is a kind of call for protective measures and preventive checks of roofs, eaves, drains, window sills, and the integrity and reliability of waterproofing. If you correctly carry out all the work to eliminate efflorescence on brick with your own hands or take preventive actions to prevent the appearance of efflorescence, then your head and conscience will be free for a long time from solving such a problem.

Why is efflorescence on brick dangerous?

The fight against efflorescence on bricks must be carried out immediately if for some reason you have neglected preventive measures. And efficiency here is not at all lost in aesthetic form. The danger lies in many factors.

If you don’t get rid of efflorescence on the brick of your house in time, the process will go further and the salt will begin to crystallize, turning into salty flakes that are toxic to the wall, which experts call “salt corrosion.” The brick is destroyed from the inside, and chips appear on the outside; the process is activated during seasonal temperature changes, which will lead to the destruction of the brick and masonry, and subsequently the entire structure of the building.

How to remove efflorescence on brick with your own hands

If you think that efflorescence can be easily washed off with a stream of water and this procedure can solve the problem of plaque, as well as avoid the consequences of a salt visit, you are mistaken and you definitely need to read this material to the end.

It is strictly forbidden to wash off efflorescence from bricks. The brick absorbs water, which will dissolve the salts contained within the building material inside and bring them out to happily crystallize outside at the first temperature opportunity.

Removing efflorescence from the surface of a brick with your own hands should be carried out in several stages. The main thing is to comply with everything technical specifications and do everything carefully and carefully.

So, are you ready? We begin to clean off the efflorescence from the surface of the brickwork.

The chemical composition of efflorescence can vary significantly and therefore each case of salt deposition on a brick must be considered individually in order to understand what composition of the washer will need to be used. To do this, it is necessary to carry out a test wash on small area walls. You can start testing with a universal remover, dissolving it in water according to the instructions and then applying it with a brush to the damaged areas of the brick. Don't forget about gloves so as not to damage your hands, and preferably wear glasses. The remover contains acids and is often aggressive, which can cause chemical burns.

You can also prepare the wash yourself. You will need a two to four percent solution of hydrochloric acid - this is in difficult cases. And in the rest - normal detergent and to one of the above options add two or three tablespoons of vinegar. Mix everything well in a bucket of water. The second solution option is to dissolve a bottle of rubbing alcohol in a bucket of water.

The solution should be applied with a roller or brush - it depends on individual preference and comfort.

A couple of minutes after applying any solution, you can thoroughly rinse everything off with water from a high-pressure hose.

Then the wall should dry and we can move on to next stage Removing efflorescence from bricks with your own hands is hydrophobization or waterproofing. Simply put, we create a water-repellent film by impregnating the wall with substances based on silicone or acrylic components. The protective solution is capable of penetrating several centimeters deep into the brick, becoming a kind of armor for the entire structure of the house.

After the following procedures, we get the following effects:

• Brick walls become impenetrable to all natural precipitation.
• The strength of the building material increases significantly.
• A brick wall will look clean and well-groomed for many years. The percentage of settling dust is minimal and is easily washed off by rain.
• The salt is completely preserved inside the brick and has no chance of any movement or reaction. But the brick does not lose the ability to “breathe”, which is very important for interior spaces. Microscopic air bubbles will tightly grab the water molecules on the surface, preventing moisture from getting inside the brick to the salts to release them. And after the rains, the drying process brick walls, thanks to this procedure, it will become uniform and will take much less time.

Preventing the appearance of efflorescence on bricks

To prevent the appearance of efflorescence on brick, our grandparents had many recipes in stock. For example, in cement mortar that was prepared for construction brick house, added chicken eggs. But modern people there is no need to be cunning with inventions, especially since there are a lot of chemical and organic solutions that prevent the problem and reliably control salts and moisture.

For self-prevention of efflorescence on bricks, any microfoaming agents-hydrophobizers based on naphthan, rosin (resin) and fatty acids (regular vegetable oil) acids, as well as organosilicon compounds. It is advisable, once every few years, to treat the brickwork of your walls with such solutions.

Upon completion of construction and application protective agent, let the walls “rest” and dry. Don't start right away Finishing work. If you completed construction of a house in the summer, then best time dry the house - winter. Moreover, hydrochloric lime dissolves perfectly at sub-zero temperatures.

During construction, under no circumstances should the masonry be allowed to become waterlogged. Therefore, it is better to suspend construction during the autumn-winter season, and reliably preserve the already rebuilt areas.

There is an opinion that before starting construction, bricks should be soaked. So this is a huge misconception. This cannot be done, as well as diluting the cementitious solution.

For convenience, we have compiled preventive measures to prevent the appearance of salt solution on bricks:

• Bricks should be purchased from a reliable and trusted manufacturer. It is impossible to determine the presence and amount of salts in a brick by looking at it. Reviews from customers and professionals to help you before purchasing.
• The cement mortar should be thick enough and always fresh, and not yesterday’s, diluted with water.
• Use only coarse and well-washed sand for the solution.
• Do not use any additives in cement mortar. Even anti-frost ones.
• Work with masonry only in dry weather. The ideal season for construction is summer.
• Preserve and cover the unfinished masonry from weather precipitation, or better yet, drive the masonry under the roof as quickly as possible.
• Handle carefully cement mortar so as not to stain the walls of the house. And remove any spilled solution with a dry brush without delay. If the solution has had time to dry, remove it with a damp sponge - this is worse than in the first option, but cleaning is extremely necessary.
• Upon completion of the masonry work and its completely dry, the façade is coated with a water-repellent or water-repellent composition.
• It is very important to ensure the construction is reliable and efficient drainage system, awnings and drains, so that even facades protected by solutions have minimal exposure to water.

White plaque on the external walls of buildings, that is, efflorescence, is a common occurrence. Its essence lies in a kind of natural “evaporation” of water-soluble salts contained in brick and mortar. Subject to the law of capillary movement, moisture, evaporating, dissolves and simultaneously carries with it salts, which crystallize at the exit points on the walls in the form of untidy white spots. And although the entire wall can become “salty,” this is only a small part of the water-soluble salts contained in the building material.

Once the efflorescence appears, it will not go away on its own. Disfiguring the appearance of the building, they will gradually destroy the surface of the facing brick. Salt crystallization creates stress on certain area and chips appear on the brick that look like scales.

On the other hand, efflorescence is a consequence. The reason lies in excess moisture in the brick itself. She has a strong destructive force. Unprotected brick absorbs moisture, which, freezing in the autumn-winter period, tears the brick from the inside. Therefore, efflorescence “signals” the need for protective measures: checking the roof, drains, window sills, eaves and waterproofing.

The appearance of efflorescence is not a death sentence. You can fight this phenomenon, since it has already manifested itself “in all its glory,” but it can also be prevented, saving yourself from headaches for several years to come.

Causes of efflorescence

Salts of various origins are found in nature in huge quantities. It is necessary to take into account circumstances independent of human will, which are a constant source of the threat of efflorescence:

• Alumina is a raw material for making bricks. Porous structure ceramic bricks perfectly absorbs moisture, which dissolves salts. During the evaporation process, the salt remains on the surface of the bricks;
• water from a natural source, the composition of which may be rich in salts;
• sand is one of the components for preparing the solution. Taken in pure form from the quarry without subsequent washing, it is able to “over-salt” the future wall;
• soil, and exactly in the place where the house should be located according to the plan;
• natural sediments in all forms that carry aggressive substances, especially if a chemical plant is located nearby.

Man breaking established rules and instructions and using low-quality material, is also able to make a “feasible contribution” to the formation of efflorescence:

• violating the proportions of the components in the process of preparing the working solution (excess water or anti-frost additives, especially in winter masonry, guarantees the appearance of efflorescence),
• using cement-sand and lime mortars or bricks with a high lime content,
• producing low-quality bricks (the use of additives that promote firing of bricks at a lower temperature reduces the cost of its production, but significantly worsens the quality),

Improper waterproofing can also cause efflorescence on the brick.

• pre-soaking the bricks, which by their nature are “stuffed” with salts (the more moisture the brick absorbs, the more salts will dissolve; therefore, when the water evaporates, the salt is guaranteed to come to the surface),

• neglecting to protect the masonry from rain and snow.

If, when buying a brick, the developer is completely dependent on the integrity of the manufacturer, then in other respects, compliance with instructions and technologies will significantly minimize the chance of becoming the “happy” owner of mutilated walls.

Anti-salt measures

Measures to combat efflorescence during production process include several important points. Necessary:

1. Disturb the mechanism of the process of dissolving salts in the masonry and their subsequent removal to the surface of the brick. To do this, you need to introduce special additives into the solution that can replace lime and increase the plasticity of the solution. It is the convenient application of the mortar, which binds together and ensures an even load between the bricks, that plays an important role. Our ancestors also used such additives, the most famous of which were chicken eggs. Microfoaming agents-water-repellents based on naphthenic (from petroleum), resin (rosin) or fatty acids(vegetable oil), as well as organosilicon compounds.

Thanks to the smallest air bubbles, the moisture will be locked in the solution, unable to be absorbed into the brick, dissolve the salts and bring them to the surface. The drying process of the wall will occur evenly throughout the entire volume.

2. Follow the process of drying the walls. Cannot be carried out plastering work with damp masonry. Often, a house that is completely rebuilt in the summer begins to be dried from the inside in the winter, while simultaneously plastering the walls. But calcium hydroxide (lime) dissolves better at low temperatures. The difference in partial pressures and temperatures provokes the forced displacement of moisture in the room and lime to outer surface walls. In the spring, efflorescence on the brick will appear throughout the building.

3. Avoid overmoistening the masonry. To do this, you need to cover the masonry from precipitation and not engage in construction work in the autumn-winter period. Do not soak the bricks or dilute the mortar. (Let's think about additives that can hold water in solution).

The opinion that efflorescence is easily washed off with water once and for all is completely wrong. Water is absorbed into the brick, causing the salts inside to dissolve and crystallize on the working surface.

A high-quality efflorescence removal operation usually takes place in several stages:

1. Cleaning a brick surface special means. Efflorescences may vary in their chemical composition, which may require the selection of a specific cleaner.

1. If you decide to remove efflorescence on your own, you need to test the product for small area. Because the chemical composition efflorescence is varied, it may happen that even a universal remover will not help and you will have to experiment with other substances. You need to dissolve the remover in water according to the instructions and apply it to the required areas with a brush. Since removers contain surfactants and various acids, it is necessary to work in gloves, glasses and a hat.

In the absence of opportunity or funds, the wash can be prepared at home. For this, hydrochloric acid (2-4% solution) or detergent and 2-3 tablespoons of vinegar diluted in a bucket of water are suitable.

1. The duration of action of the drug is indicated in the instructions; it will take minutes. Residues are washed off with water under pressure (from a hose or high-pressure washer).

1. This is followed by drying the wall and its subsequent hydrophobization - creating a waterproof surface by impregnation with organosilicon or acrylic-based substances. Water repellents can be absorbed to a depth of several centimeters.

The treated surface acquires new qualities:

• It becomes completely invulnerable to rain and fog, the water simply flows off it.
• The strength of the brick increases.
• The walls always look clean - less dust settles and is easily washed off by rain.
• The release of salt to the surface outside and inside the house is excluded - the water repellent, while maintaining the vapor permeability of the walls, blocks the movement of salts.

There are tricks against salt

So that the future home pleases the eye with clean smooth walls and corresponds to the status of its owner, it is necessary to adhere to simple rules, time-tested:

• When drawing up the project, the climatic conditions of the region must be taken into account, in connection with which protection of the walls from getting wet will be developed.
• There must be a ventilated gap between the wall, insulation and cladding.
• Must complete horizontal waterproofing foundation.
• Use in facade finishing ready-made dry mixtures that just need to be diluted with water.

Efflorescence can appear in the most unexpected places. But modern construction experience and special drugs will help prevent or eliminate this phenomenon.
