Wet walls in a brick or panel house: causes and consequences. Why the walls in the house sweat and get wet and how to fix it Dampness in the corner of the room what to do

There is a saying: any apartment is good if it has its own. The interior can be decorated to your liking, equipping a gym in the bedroom, getting a cat, a dog. Having your own apartment is a lot of pluses, with occasional problems.

A common problem is damp walls. Dampness appears in late autumn and winter, with a difference in temperature inside the home and outside. Corner apartments and those located on the upper / lower floors of the building are subject to it.

raw wall

Wet walls are the trouble of the owners. First, the wallpaper peels off, the plaster collapses, mold starts. It is difficult to fight with her, her presence is bad for health. There are several reasons why walls get wet.

recent renovation

Often partitions get wet after recent repairs. This is the most harmless reason. There is no need to eliminate it, it disappears on its own over time. A little humidity inside the apartment, after repair, is easy to explain.

Used cement mortar contains water. Poor ventilation plus damp weather affects the rate of moisture evaporation. Therefore, worries about humidity are groundless.

Moisture seeps in from above

External moisture

The walls of apartments on the upper floors get wet as a result of the poor quality of the system for collecting and draining water from the roof, poor seam processing waterproofing material. Moisture seeps through microscopic cracks.

Panel buildings are also vulnerable. Violation of construction technology leads to depressurization of the seams between the panels.

Checking ventilation

Insufficient ventilation

Cause of damp walls in rooms with high humidity- poor ventilation. It's about the bathroom and kitchen. The efficiency of ventilation is determined by opening the window and attaching a piece of paper to the vent grille. If the leaf sticks to the ventilation grill, the air exchange is not disturbed. If the paper falls, the ventilation is not working and needs to be cleaned.

High indoor humidity

Wet fumes penetrate from the basement with poor waterproofing. Brick has different moisture resistance. Silicate has the lowest performance.

The problem occurs in multi-apartment buildings with basements and poor waterproofing. Parts of the walls near the floor are damp.

Excess moisture appears after the installation of airtight plastic windows. Periodic ventilation of the room eliminates the problem, removes condensation on the windows.

wall freezing

Freezing occurs with poor thermal insulation. It is reduced by insufficient wall thickness, opening interpanel seams, cracks.

Ways to get rid of moisture

This can be done on your own or contact specialized organizations.

Bituminous mastic

Getting rid of outdoor moisture

Some experience will help in solving the issue. If not, follow our recommendations:

• find a weak spot that allows water to enter;
• isolate it with bituminous mastic;
• remove the damaged coating from the inside, apply mastic, plaster the surface;
• cover the treated area with a primer, paint or wallpaper.

Ventilation, electric heating will partially correct the situation.

Leaks in apartment building engaged in services for maintenance at home.

Exhaust fan in the bathroom

Restoration of ventilation

Violation of ventilation of a local nature is easily eliminated. remove the cause of the violation of ventilation, move the curtains, rearrange the cabinet.

Blockages of ventilation shafts are removed independently if they are localized near the grate. The protective grille is removed, the blockage area is vacuumed or cleaned.

A clean draft-free vent requires the help of professionals. Independent solution of the problem will not bring results.

Often the violation of ventilation occurs due to the fault of the neighbors from above. Illegal housing redevelopments change the ventilation stack, which affects the air movement of other apartments. Specialists will be able to detect innovations and fix the problem. Cleaning mines in old houses is also their task.

The ventilation system is normal, but the air flow is bad? The reason is plastic windows, open them more often, put them on micro-ventilation.

Installation forced ventilation- great way out. Poor air intake into the apartment requires the installation of supply ventilation, poor removal - exhaust. Look for compact, cheap devices that provide normal air exchange.

Instead of a lattice, install exhaust fan in the bathroom. There are fans with a timer that periodically turn on and off. It is advisable to purchase a fan with check valve. If the neighbors put in a similar device, with more power, it will drive the air back into the apartment. The kitchen needs to be equipped with a hood.

Elimination of high humidity

Dealing with moisture on the walls due to the basement is difficult. There are many reasons: high groundwater level, improper waterproofing. Basement draining should be done by professionals.

Dampness enters the apartment through microscopic cracks in the floor. Remove the flooring, treat the base with mastic, lay the flooring in place, treating it with an antifungal agent. Seal the seams thoroughly with sealant.

Warming from the outside

Freezing liquidation

The best prevention of freezing is the insulation of external walls. Owners of the first floors can do this on their own, everything above is in the competence of specialists from construction companies.

Internal insulation causes mixed reviews. On the one hand, the interior decoration will lead to the accumulation of condensate between the wall and the insulation, on the other hand, the lack of the possibility of external insulation is a way out of the situation.

Stages of internal insulation:

1. The walls are cleaned of old wallpaper or paint.
2. The surface is levelled.
3. A frame made of metal profiles is mounted, and fastened to the wall with self-tapping screws, dowels.
4. Insulation is laid in the frame cells.
5. Everything is sheathed with drywall.
6. The surface is plastered.

An alternative method of insulation is “warm” plaster; instead of sand, materials with increased thermal insulation properties(expanded clay chips, expanded polystyrene grains, sawdust, etc.). Possesses high adhesion, does not demand alignment of walls. Apply in the usual way.

black mold

Mold control

Black mold forms on walls and ceilings - microscopic fungi, the spores of which are carried through the air, falling on Construction Materials. With a favorable (moist) environment, spores develop, give a mycelium (mycelium).

Mold control:

1. Remove wallpaper and paint from the walls - you need to work in a respirator so that the fungus does not enter the respiratory tract. The working tool is a hard metal brush or spatula.
2. Treat the surface with an antiseptic - previously actively used: vinegar, baking soda, hydrogen peroxide. Some still use home remedies to combat the fungus today. Experts advise using factory-made antiseptic preparations (Fongifluid, Senezh Effo, etc.). They are more efficient.
3. After a few hours, walk along the wall with a dry brush, remove decay products of microorganisms, wash warm water, dry.
4. After a day, apply a deep penetration primer.
5. When it dries, apply plaster.
6. The final stage is painting or wallpapering. You need to paint with means for wet rooms. Glue is used with antifungal properties.

Where to go when the walls are damp?

If they continue to get damp, despite attempts to fix the problem, an application is written to the management company. You need to make a copy of this document.

The company must send the master to inspect the apartment, draw up an act on dampness, the reasons for its occurrence. The owner is entitled to receive a copy of it.

After the company is obliged to set the timing of the repair and carry it out. If the repair is poor or the agreed deadlines are not met, copies of the application and act must be contacted by the relevant authorities to resolve the disputed issue.

Dampness in the apartment must be dealt with. She is the source of various diseases. Without delaying the case, eliminate the factors that contribute to its appearance. It is unnecessary to raise the humidity yourself by drying the laundry in the room. If not possible, dry with a running hood. This will allow the apartment to remain dry, comfortable, safe for living.

Additional information on the topic of the article can be obtained from the video.

The following video will tell you how to get rid of the fungus on the walls.

In contact with

A certain level of humidity is always present in the house: washing, cleaning the rooms, washing and even cooking. But you need to make sure that the humidity does not rise above the norm.

The presence of excess humidity in a private house is not only wet walls, moldy corners, bad smell and damaged furniture, but also dysfunctions of the respiratory system, allergic diseases and other medical problems. How to determine the optimal level of humidity in the house? This is done using a hygroscope. The optimal value of indoor air humidity for comfortable living a person is considered 40 - 60%. Exceeding this indicator is fraught with the appearance of problems, in the form of condensate, stale air and fungus.

Causes of dampness in a private house

There are not so many reasons for the appearance of dampness in the house; work to eliminate them is quite accessible to any owner.

Reason #1. Incorrect foundation waterproofing

This means that when laying the foundation, violations were made during the arrangement of horizontal waterproofing. Now the impact of groundwater leads to gray-green stripes under the plinth, damp and falling off the wallpaper at the bottom, corners covered with mold.

To change the situation, it is necessary to develop soil along the perimeter of the foundation and apply vertical waterproofing of the foundation walls. This will not be easy and not cheap, but there are no other technical processes that guarantee complete elimination of dampness.

Reason number 2. Basement waterproofing failures

This is usually caused by errors in basement waterproofing. ground water, affecting the floor, walls and ceiling of the basement, leads to the formation of dampness in the rooms located above the basement. Moreover, underground water can flood the basement. Then, after pumping out the liquid, it will be necessary to carry out vertical waterproofing of the walls, as in the first case.

If there is no water in the basement, but only dampness, then coating and injection waterproofing will help here. Processing must be carried out on all surfaces of the basement.

Reason number 3. leaking roof

When it rains, it will be very easy to find the place of the leak. To fix the problem, it is necessary to restore the defects of the roof by making partial repairs in the area of ​​leakage. This process does not require large material costs and can be done by hand.

Reason number 4. Lack of blind area

The blind area must be made according to certain rules: have a slope of 2-3 ° from the house, and the minimum width should be 70 cm. Otherwise, the completed area around the house will footpath and will not perform the function of protecting the house from water.

The base of the blind area is a layer of clay, then a layer of sand and gravel is poured, carefully tamped and poured with concrete mortar or laid paving slabs. It is really possible to do such work with your own hands, and the cost of the necessary building materials will not hit the budget.

Reason number 5. Insufficient wall insulation

In this case, dampness occurs as a result of the rapid formation of condensate, due to temperature differences on the outer and inner side of the wall. You can get rid of this trouble as a result of work on the insulation of the facade of the house from the outside. The procedure takes time and money. You can perform insulation yourself or with the involvement of professionals.

Reason number 6. Deterioration of the drainage system

The failure of the gutter can also cause dampness in the house. Rainwater, flowing down the wall, will cause it to get wet, and this will serve as the basis for trouble. Gutter system requires constant monitoring, preventive cleaning and replacement of defective areas in case of damage. These works are within the power of the owner of the house, and the cost depends on the price of the drain used.

Reason number 7. Ventilation system

For comfortable living and ensuring standard humidity, any room must be ventilated. According to state standards, within an hour there should be a complete exchange of air in the room. Therefore, even when building a house, you need to pay attention to the ventilation system. If the house is not new, and got as a result of the purchase, in case of dampness, it is necessary to check the ventilation ducts.

If they are clogged, clean them. If these measures are not enough, then it is necessary to install additional ventilation ducts, check valves or replace the natural air exchange system with a forced-exhaust option. This is a serious procedure and can entail large material costs, so it is better to contact specialists.

Reason number 8. Plastic windows

Installation plastic double-glazed windows can result in a violation of air exchange, which will lead to the formation of condensate and other problems resulting from this. Therefore, when purchasing plastic windows, pay attention to the presence of a built-in ventilation valve, and during operation, do not forget to set them to the ventilation mode. These methods do not require material investments and are available to any inhabitant of the house.

Reason number 9. Insufficient heating

The inefficiency of the heating system will cause dampness in the house. To fix this problem, you need to contact the experts. The optimal solution can become a setting circulation pump, taps for air release in places of traffic jams or additional heating radiators. This is a time-consuming and expensive undertaking, so it is better to trust professionals.

Reason number 10. Source of dampness inside the house

It happens that doing household chores is associated with a large release of condensate in the form of steam. These are frequent washing, digestion, forced drying of things indoors, cooking, canning blanks for the winter. In order to prevent the appearance of dampness in the house, it is necessary to reduce the intensity and volume of the listed cases. This is in the competence of each hostess.

Why is the floor and wall damp in the house

Damp wall in the house

Dampness on the walls is a frequent occurrence, part of the wall, the whole wall or just the corner of the room can become damp.

Effects high level moisture:

• Wallpaper is peeling off;
• Darken the walls;
• A fungus appears
• Heavy indoor air;
• The temperature is dropping.

Of course, first you need to find out why dampness appeared, sometimes the reasons are immediately obvious and visible right away, sometimes you need to carry out prevention and look at the result.

Cause classification

Sometimes, to eliminate dampness, you just need to be attentive, constantly monitor the condition of the house and detect problems on initial stage when they are much easier to deal with.

Damp floor in the house

If the floor is damp, then most likely the problem is in the basement, poor waterproofing, lack of ventilation. That is, the reasons are almost the same as in the case of the wall.

In general, here you need to judge by the condition of the floor, or it can be dried and the problem will be solved by itself (you just had excessive humidity in the room) or you will need to completely change and re-lay the floor.

Be sure to take care of the waterproofing of the floor (cover it with a film), seal all the cracks in the basement (if it is under the house).

Perhaps the reason is a violation of the waterproofing of the foundation (in this case, you will have to dig out and look for a problem area and eliminate it).

In general, it is most difficult to begin work on identifying and finding the causes of dampness in the floor and walls.

Do not forget about mold and fungus, if during the inspection of the premises you find mold, you need to remove it and process this place so that it does not reappear.

Tailored for you:

The problem of damp walls, unfortunately, is familiar to many residents of both apartments and private households. The consequences of this process not only cause discomfort (decrease in room temperature) or material losses (wallpaper peeling off, swelling of linoleum or laminate), but can also be harmful to health. Mold and fungus, which are formed due to dampness, are extremely dangerous for the body.

Causes of rawness brick walls divided into two types: external and internal.

Why is the brick wall damp inside

The main prerequisites for dampness of the inner surface of the wall:

• poor ventilation of the premises, faulty ventilation system;
• weak heating system;
• constant dampness inside the house (for example, due to faulty pipelines in the basement).

Weak heating. Perhaps the heating system simply does not warm up the damp wall. The problem is solved by installing a heater near a damp wall, or a stationary radiator.

Wear ventilation system can also cause dampness. Often the walls begin to dampen in old houses when new ones are installed, plastic windows, which prevent the ingress of air from the street. The problem is solved with the help of re-equipment of ventilation. More cheap option- installation of hoods or regular ventilation of the house.

Quite often, the walls in the bathroom and in the kitchen become damp. These areas have the most moisture. If the rooms are poorly ventilated, it is worth installing additional hoods.

Residents of private houses or apartments on the ground floor may encounter the problem of damp walls (and floors) if there is a basement below that does not have a floor (soil). This problem can only be solved with the help of additional waterproofing.

Why is the wall damp outside the house

Among the main reasons for dampness of the outer surface of a brick wall:

• microcracks in masonry;
• high thermal conductivity of the wall.

Microcracks in mortar or brick lead to the fact that rainwater or melted snow penetrate the wall. In order to find out exactly whether this is the cause of the dampness of the outer surface of the wall, it is worth watching it during rain or snow. You can fix the problem with hydrophobic impregnation.

High thermal conductivity - the most common cause walls dampening. Determining this is just as easy. In frosts, inside the house such a wall will be very cold, and outside it may become covered with frost. The only solution to the problem is to insulate the outer surface of the wall.

Why does the wall of a brick house get damp?

Apartment owners quite often face such a problem as a wet wall in an apartment. Especially often trouble occurs in winter period when the temperature difference between the outside and inside the room is very large and condensate begins to settle on the walls of the building. The automatic question arises of what to do with a wet wall in the apartment and how to get rid of this problem. If we neglect to correct the situation and leave everything as it is, then it is quite possible that black mold will subsequently form on the walls, which is extremely dangerous for human health, provokes respiratory diseases and causes serious complications.

In this article, readers will be able to find out why the walls in the apartment are wet and if the wall in the apartment gets damp, what to do and what actions to take first.

The reasons why the walls in the apartment are damp

Before proceeding to solve the problem, you should answer the question of why the walls in the apartment get wet and at what stage the damage is. If the degree of moisture in the wall is very high, then you will need to make a radical decision, and, without delay, correct the situation as quickly as possible.

The first sign that indicates that the walls are getting wet in the apartment is that its surface becomes wet, the wallpaper begins to peel off and the plaster crumbles, and at the final stage the wall is covered with a layer of black mold. If such a phenomenon occurs, then it is extremely important to first determine why the walls in the apartment are damp. In the future, this will allow you to choose the right method for correcting the situation, including the necessary fixtures and materials that will be used. The main reasons why the walls in the apartment get very wet are the following:

1. Insufficient wall insulation or low waterproofing quite often lead to the walls getting wet in the apartment. As a rule, this is observed in old houses and in apartments located on the highest or lowest floors. It should be noted that wet walls in an apartment on the top floor or on the first floor appear in the autumn-spring period, and not in winter, as in other cases.
2. There is high humidity in the room or at the location of the dwelling. If we are talking about a brick building, then a large amount of moisture rises from the basement, resulting in a wet and ugly wall in the apartment.
3. Insufficient ventilation can also cause the wall in the apartment to become damp. For the same reason, the windows in the room fog up.
4. Quite often, the wall in the corner apartment gets damp, what to do in such a situation worries many owners. This is due precisely to the inconvenient location of the living space and the fact that the walls of such a dwelling are exposed to negative factors much more than in other apartments.
5. The room has recently been renovated. This reason, explaining why the walls in the apartment become damp, is the only one in which such a consequence is considered natural. As a rule, during the repair a large amount of materials are used that contain water and after the completion of the necessary work, moisture remains in the walls, especially if the room is poorly ventilated. In such a situation, you should not worry and worry about what to do when the walls in the apartment get wet, but it is better to wait a little time and the moisture will dry itself.

What to do if the wall in the apartment gets wet?

Having figured out why the wall in the apartment gets wet, we found out that there can be several reasons for the emergence and development of such a situation at once. Accordingly, in order to answer the question of what to do if the wall in the apartment becomes damp, it is possible only if the cause of the problem is precisely determined.

For example, if a wall in a renovated apartment becomes damp, no special manipulations are required. It is enough to ventilate the apartment well and hold the windows open for a while. In the case of repair work in the winter, it is necessary to provide heat in the apartment so that the moisture remaining after the repair evaporates. If the heating is good, then batteries are enough for this purpose, but if they do not cope, then you will need to turn on the heater.

In case of problems with ventilation, if the wall in the apartment becomes damp, only an experienced master will tell you what to do, although at the initial stage you can cope with difficult situation on one's own. It is enough to remove objects that interfere with high-quality air ventilation. For example, if moisture accumulates in a small area behind the curtains, then it is quite possible to raise or remove the curtain altogether, and move the furniture away. In this case, if the wall in the apartment gets wet, such actions can quickly deal with the problem. In general, the problem of what to do when the walls become damp in the apartment in the absence of good ventilation is solved in a complex way. You will need to check all the vents that are inside the apartment and ventilate the room more often. Additionally, it is worth putting a hood in the kitchen so that excess moisture is drawn out.

As we have already noted, the reason why the wall in the apartment gets wet may be the lack of high-quality waterproofing. This problem is more serious and difficult to deal with. There can be only one solution here - to isolate the wall surface sufficiently. As a rule, if the walls get wet in the apartment, then the seams on the outside of the building have become unusable. What to do when the walls get wet in the apartment? in this case, only a specialist will tell you. This will require serious intervention, since ordinary ventilation cannot solve the problem.

What to do if wet walls appear in the apartment in winter? This issue worries many homeowners who are faced with such a problem. Moreover, if you take independent action in this case, you can only worsen the situation. Many do not have the opportunity to perform additional insulation from the outside of the building and, laying insulation from the inside, only worsen the situation by shifting the dew point. As a result, a wet wall in an apartment will become even wetter in winter, and later moisture will begin to collect in a puddle under the insulation. It is extremely important to understand here that even if the owner of the apartment is an experienced climber and builder, you should not do the insulation work on your own, but best of all, trust experienced craftsmen who will do all the work with the highest quality.

For a more complete picture of what to do when the wall in the apartment gets wet, it is worth deciding what tools and materials are needed to carry out such work, as well as what technologies are most suitable for solving the current problem.

Necessary tools for work

If the walls in the apartment become damp what to do, we try to understand this article. Several options for correcting the situation have already been proposed, however, it would be most correct to contact specialists who can certainly fix the problem. If, however, it is possible to repair work to eliminate the reason why the walls are wet in the apartment, it is worth preparing in advance necessary tools. The mandatory list includes the following items:

• roulette;
• level;
• a hammer;
• hacksaw;
• stapler and staples;
• construction thread or twine;
• trowel;
• spatulas.

On this, the list is not complete. It is likely that other devices, tools, for special work will be required. Here, each performer determines the toolkit independently, taking into account the peculiarities of eliminating the problem. In addition to tools, you need to take care of buying special materials that are presented on the construction market. Next, consider some of the nuances of insulation and waterproofing.

How is thermal insulation carried out in rooms where the wall is damp

As an answer to the question of what to do when the walls in the apartment get wet, we can offer to strengthen the existing thermal insulation. This will eliminate the penetration of moisture and cold from the outside and will give the greatest effect. It is important that the insulation is carried out both outside and inside.

Unfortunately, it is almost impossible to do such work on your own. This option is suitable for detached buildings, ground floors, as well as buildings where there is no need to climb to a considerable height in order to complete the finish.

It is extremely important to choose the right thermal insulation materials that are presented on the construction market in in large numbers. To carry out the work, it is best to choose proven manufacturers who pay attention to the high quality characteristics of materials. It is important to remember here that even if wet walls appeared in an apartment on the top floor, then it is worth insulating the area from the outside, and not from the inside.

If we are talking about an apartment building, then it is almost impossible to insulate the walls in this case, so you will have to limit yourself to the interior decoration of the walls, which, if the work is done correctly, will give a guaranteed high-quality result. In this case, it is worth paying attention to two important parameters:

• when the wall in the apartment gets wet, you must first determine the water absorption coefficient of the material used. It is from this indicator that the speed and degree of moisture removal from the apartment depends. The lower the indicator, the better the water-repellent properties of the material will be. This will make it possible to eliminate such a problem as a wet wall in an apartment in winter;
• to determine what to do when the walls get wet in the apartment, it is worth insulating the walls, but at the same time take into account the thickness of the layer purchased for finishing the material. Here it is important to make such a density at which there will be a sufficient coefficient of thermal conductivity. If the coefficient is small, then the layer will need to be made thin.

Only taking into account all these points, it is possible to achieve a significant decrease in humidity in the apartment and return the wall to its original appearance. To answer the question why there are wet walls in the apartment and what to do if the wall gets wet in the apartment, it is enough to study the theoretical aspects of this issue and contact a specialist for practical advice.

How to carry out thermal insulation of the foundation if the wall in the apartment becomes damp?

What to do if the walls in the apartment are wet in winter and the apartment is located on the first floor of the house? In fact, here the problem can be solved quite easily. You only need to insulate the foundation. This action especially relevant for those who are interested in giving their housing increased sound insulation. This will solve not only the problem of a wet wall in the apartment in winter, but also eliminate noise and unpleasant sounds.

Here it is worth giving preference to materials that have a high noise absorption coefficient, since this will save time for repairs and the installation of sound insulation. The flammability class of materials is extremely important in order to exclude the possibility of sudden ignition. The best option can become a class G1 material, since thermal insulation, even during combustion, does not provoke the appearance of an open flame source. It is worth highlighting several of the most common heaters and at the same time soundproofing materials. The list of the most famous includes such as:

• mineral wool- This is a very common material that has a low cost and excellent specifications. When the walls get wet in the apartment, what an experienced master will be able to advise and most likely, he will say that, despite good performance, mineral wool for insulation is not the best a good choice. The thing is that the material has a high coefficient of water absorption;
• Styrofoam is a great choice if you don't know what to do if a wall gets wet in your apartment. The material is suitable for interior and exterior finish while absorbing virtually no moisture. The disadvantage is the low ability to transmit steam. This does not allow air to circulate freely. In addition, when ignited, the foam begins to release toxins;
• "Warm" plaster, which is used for wall insulation from the inside and outside. The use of such material is especially relevant if wet walls appear in an apartment on the top floor. This is due to the fact that the material is not a traditional insulation and does not absorb moisture. In addition, such plaster has excellent soundproofing performance. As a disadvantage, the excessive weight of the coating can be noted. The material is not suitable for private houses, because it needs a reinforced foundation;
• cork insulation is used for interior decoration. If you have no idea what to do when the wall in the apartment gets wet, then you should pay attention to this particular material, which has a low thermal conductivity, but at the same time has a small weight. The disadvantage of the coating is increased flammability.

Surface insulation scheme if the wall gets wet in the apartment

Many apartment owners are interested in the question of where to go if the wall is wet in the apartment and what to do in such cases. In fact, there can be only one solution - to visit a construction company that provides such services. This immediately provides several benefits. On the one hand, you will decide what to do when the wall in the apartment gets wet, and on the other hand, you will receive a high-quality work that will not need to be reworked in the future. Another important point is that the master has an idea of ​​​​what to do if the wall is wet in the apartment, which means that he will perform all the necessary work strictly according to the technology. For example, we can give the following algorithm for finishing a section of a wall.

1. The working site is being prepared, namely, it is cleaned of dust and debris, after which leveling plaster and a primer are applied to it. The base for further work is ready and now you need to glue the foam on it, and then fix it with special dowels.
2. Each sheet needs to be treated with an adhesive, and then pressed against the prepared surface and pressed well. It is best to arrange the sheets in a checkerboard pattern, thereby increasing the strength of the structure.
3. Fastening with dowels is carried out along the perimeter, while holes will have to be drilled in the material.
4. After gluing and fixing the sheets, finished finish covered with reinforcing mesh and the overall structure is plastered. The walls are decorated with paint, and a layer of decorative plaster is applied to it.

Most simple option wall insulation, which determines what to do when the wall in the apartment becomes damp, is the insulation of the surface from the outside with the help of special “warm” plaster. The material is applied to plaster mesh and then decorated.

Wall insulation from the inside if the wall in the apartment is damp

This option remains the only one when the homeowner does not know what to do when the wall in the corner apartment gets very damp and where to turn if the apartment has a wet wall. In fact, if it is not possible to insulate the structure from the outside, then it is important to consider the procedure for insulating the walls from the inside. Experts recommend using any of the above materials in this case, however, it is worth choosing a heater taking into account individual sizes walls, as well as from the financial capabilities of the owners of the premises. From this point of view, it is still not worth using foam plastic, since it can easily ignite and thereby threaten the lives of residents.

The whole process of warming takes place in several stages. Each of their stages is extremely important for the overall result, since it allows you to complete the finish with the highest quality and with the expectation of long-term operation in the future. The algorithm of actions in this case is as follows:

1. Walls should be pre-prepared by cleaning from dirt and old wallpaper.
2. Impregnate the surface with a primer.
3. Assemble the frame from a metal profile or wooden bars. The fastening step should be equal to 40-60 cm.
4. The insulation is placed in the cells, if necessary, the sheets can be cut.
5. In the future, the coating is covered with plasterboard and finished with plaster.

Conclusion

If you have no idea what to think of when the wall in the apartment gets wet, then we recommend that you turn to experienced craftsmen who, in as soon as possible They will do all the finishing work and save you from this problem.

In houses or apartments, a situation often arises when the corners or walls begin to get damp. As a result of this, the wall darkens, the wallpaper begins to peel off, and a characteristic smell of dampness appears in the apartment. Such consequences do not add attractiveness to the room. But other than that, a damp indoor surface is an ideal environment for mold to thrive. And fungus spores are the cause of the emergence and development of numerous respiratory diseases.

What is the reason for the appearance of moisture on the surface of the walls, and how to deal with this problem? What causes dampness in an apartment?

The reasons may be:

• external;
• internal.

External moisture

The cause of dampness can be external moisture that gets on the walls and penetrates through microcracks or poorly sealed seams inside. More often, such a nuisance is typical for apartments on the upper floors with a poor-quality drainage system, for walls along which drainpipes run, as well as panel houses with poorly sealed joints between the plates.

In order to fix the problem, it is necessary to clean the wall from the old coating, re-plaster it from the outside, prime it, cover it with waterproofing mastic, and only then cleanly paint the resulting surface. You can independently carry out such a cycle of operations either in a private house or on the ground floor apartment building. In other cases, it will be very problematic to solve the problem of damp walls on your own due to the need to high-rise works. Therefore, you will have to turn to professionals.

Excessive humidity in the room

The simplest reason, in terms of elimination, is high humidity in the apartment. It is possible that the appearance of pockets of dampness was preceded by the replacement of windows in the room. New windows closed the openings more hermetically and worsened the ventilation of the room. In some cases, in order to avoid dampening of the walls of the apartment, it is enough to ventilate the room more often.

If this is not enough, or if the problem occurs in a room with potentially high humidity, such as a kitchen, then you can try to improve the quality of ventilation. To do this, you can put a fan on the outlet. Thus, ventilation will turn from natural to forced supply and exhaust with greater productivity.

The most common and unpleasant reason for the appearance of moisture on the walls in the room is their freezing. Specialists involved in thermal insulation of premises use the term "dew point". If you do not go deep into technical details, then this is the temperature at which the vapor turns into a liquid. That is, in relation to our case, condensation will appear on the inner surface.

If the outside air temperature is low, and the room is not warm enough, then there is a chance that the wall will freeze. After that, moisture will appear on its inner surface. The probability of dampness of the walls inside the room is even higher in the case of the presence of "cold bridges". Their role can be played, for example, by microcracks in walls or leaky joints in prefabricated houses.

How to deal with damp walls in this case? Sometimes it helps to increase the temperature in the room. In this case, the "dew point" goes inside the wall. But without extra labor, this can only be done in private houses with an autonomous heating system. This will increase the consumption of gas and money to pay for it. In apartments with central heating, the only way to raise the temperature is by increasing the number of battery sections.

Most effective method combating freezing of external walls - their additional insulation. This can be done both from the inside and outside.

Less time-consuming is the insulation of the wall from the inside. For this, one of the many heaters that are commercially available can be used. Most often, expanded polystyrene, mineral wool are used for these purposes. Less often - foam. Works on internal insulation it is quite possible to do it yourself. But this option has a number of significant drawbacks. Firstly, sheets of insulation will “eat up” precious centimeters of room space. And for rooms with a size of one and a half dozen squares, this will be noticeable. Secondly, despite all the manufacturers' statements about the absolute harmlessness of their materials, there is a possibility that harmful fumes will appear in the room. Thirdly, if the thickness of the insulation is incorrectly calculated, it may turn out that the “dew point” will be at the junction between the insulation and the wall. And then you get a hidden focus of moisture and mold. The situation is even worse than the dampness of the walls in the apartment.

At additional insulation walls it is better to give preference to outdoor work. But, again, such work can be done independently only on the ground floor and in a private house. In all other cases, the involvement of professionals is inevitable.

With external wall insulation thermal insulation material fastened to the wall with special adhesive mixtures and plastic dowels. Then a mesh is laid on top under the plaster and the surface is plastered. After stripping and sanding, you can start staining. In order to prevent moisture from rain and melting snow from getting between the insulation and the wall, a protective visor made of galvanized metal sheets is mounted on the upper end of the insulation.
