The problem of damp corners and walls often worries both residents of high-rise buildings and owners of private houses. Due to the fact that the corner of the room is damp, the walls begin to darken, the wallpaper peels off, mold appears, and the air in the room becomes heavy. Plus, during the cold season, the temperature in the rooms drops, windows are opened less often to ventilate the room, a lot of precipitation falls, and the walls themselves are not dried by the sun's rays.
Damp corners and walls are a fairly serious problem that should be addressed immediately. Damp indoors can cause various diseases and also become a gathering place for fungi and mites.
Therefore, the question of why the corners in the house become damp worries many.
The sources of dampness in the corners of rooms can be obvious or hidden. Some are easy to spot, while others will require searching. However, all the reasons why corners in the house are constantly damp are divided into two subcategories - internal (poor ventilation, insufficient heating) and external (increased thermal conductivity of the wall, penetration of water from outside, etc.).
Dampness often appears in the corners of a room in the following cases:
Attentive owners will always notice damp corners in time and determine the cause of the appearance of phlegm.
After identifying the culprit of the problem, you can begin to eliminate it:
When applying insulation from the inside, you should thermal calculations to avoid the appearance of condensation and moistening of the insulation material, as a result of which its insulating properties are lost.
In private houses or on the highest floors, the walls are often damp due to the attic.
This happens in the following cases:
Following certain rules will help reduce dampness to a minimum and prevent its occurrence in the future.
If the walls often get wet during interior spaces with high moisture (bathhouse, bathroom), then the problem is most likely ventilation system. Therefore, first of all, you should check the ventilation openings for the presence of unnecessary objects that may interfere with air circulation.
It’s easy to check how clogged the ventilation channels are: hold a burning candle to the vent and watch how the flame reacts: if it reaches towards the grate, then the channels are not clogged and there is a draft. When there is no flame response to ventilation, you need to install additional devices in order to establish air circulation.
When the holes are not clogged, but the draft is still weak, additional slots can be made at the bottom of the door for air intake. If this doesn't help either ventilation duct mount forced exhaust. Such fans are turned on only when there are no people in the room, as they can seriously harm your health.
Experts advise installing fans with a built-in humidity controller in the bathroom. When humidity rises, the fan operates automatically, eliminating air oversaturated with dampness.
If the tightness of the seams is broken and cracks appear in the walls, the corners in the room begin to become damp. In this state of affairs, there is only one way out: the waterproofing of the joints between the panels needs to be repaired, and microcracks in the walls need to be repaired.
After high-quality sealing, the walls should not gain moisture. They can become damp and leak only when the technology for sealing the seams is broken.
The main mistakes are applying sealant without preliminary repairs or using a low quality sealant.
This should also be taken into account: if waterproofing of joints is carried out in one apartment, and not in the whole house, then the problem of dampness will not disappear. Moisture will penetrate into poorly sealed seams in the apartment on the floor above or on technical floor, so although slower, she will find her way to the right room.
It happens that dampness in the house is caused by the fact that the foundation is poorly insulated. If its waterproofing is insufficient, groundwater when raised above 1.5 m can penetrate into the walls. In this case, they will get wet, mold will appear under the baseboard and in the corners, the plaster will begin to fall off, and the wallpaper will deteriorate. However, if the foundation is done correctly, it can prevent penetration groundwater.
It happens that pockets of dampness appear in the corners of an apartment after replacing ordinary windows with plastic ones. Installed windows They are very airtight, they tightly close the openings, as a result of which the ventilation of the room deteriorates. You can avoid damp walls in such cases if you know what to do.
Ventilation is often sufficient to exchange air in a room. However, if this is not enough, you can improve ventilation by installing an additional fan on the vent. Then the humidity in the room will decrease, and there will be no condensation of moisture on cold walls, in particular in corners where air exchange is reduced.
The problem of damp corners often becomes a concern during the cold season. Many people don’t even notice damp walls at first, but when the moisture turns into mold, the problem should be taken seriously. Constant dampness in the room causes fungi, mites and centipedes to multiply, and residents may develop various diseases, shortness of breath, cough, and allergic reactions.
The fight against excess moisture in a living space must begin immediately. This process is quite labor-intensive and sometimes requires money. However, with an accurate determination of the root cause of the increase in humidity and making the right choice effective ways combating dampness, you can forget about wet corners forever. And made if necessary new renovation in the apartment will refresh the walls and please everyone.
The problem of wet walls in the house must be taken very seriously, and if you neglect it, the consequences can be disastrous.
If the fogging of the walls has already developed into the formation of mold, then ordinary scraping is not enough, since after a short period of time it will again grow on the wall, no matter what you treat it with. Here we need to look for other solutions, and specifically, get rid of moisture in the walls.
In order to find a solution to the problem, it is necessary to determine its source, and in a particular case, find the reason why the walls in the house are sweating and getting wet.
Another important aspect To localize the resulting moisture stain on the wall and prevent it from growing, several simple measures can help. First, you need to remove all obstacles to air circulation in that place (curtains, rags, etc.), and then install a heater with a fan directed at the spot (even just a fan), this way you will improve the situation a little.
First you need to determine the source of moisture. There may be several options; we will consider each one separately.
This option most likely applies to old houses, because previously good insulation during construction we were only dreaming. Or, when building a house, they saved a lot on insulation, relying on a large number of batteries.
Signs: The house is constantly cold and damp in winter. The walls inside the room are very cold. A lot of energy goes into heating winter period.
Why is this happening: At severe frosts, the dew point in the wall moves closer to the room, and if there is insufficient heating, the wall begins to sweat. IN in this case we need to move the dew point closer to the street.
How to fix: In this case, you have two options: the first is to heat the room more strongly, but this is an additional monetary expense with dubious benefits, and the second is to insulate the walls of the house from the outside. For this you can try insulate walls with polystyrene foam, For example. Under these circumstances, thermal insulation of walls from inside the house will not help, but on the contrary, it will worsen the situation. In this case, we will shift the dew point even closer to the room. There will be even more moisture on the wall itself under the insulation, and it will gradually turn into puddles on the floor. Only external wall insulation can help here. With external insulation we will shift the dew point in the direction we need, as can be seen in the diagram. It's not very cheap, but it's reliable. And of course, keep an eye on the ventilation. Without ventilation, wet walls cannot be avoided.
This option, in most cases, applies to those who live on the top or first floors of houses. If the wall is wet below, then moisture can enter from the street through the basement, through the floor, basement, if there is insufficient waterproofing in those places. If the wall in the house gets wet or sweats at the top, most likely moisture enters through the roof, which is poorly insulated from water.
Signs: The largest spots on the walls are in the fall, in damp weather, or in the spring, when the snow begins to melt. If the room is well heated, then negative temperatures, wet spots will dry out slowly.
Why is this happening: If the roof is of poor quality, water will always find a loophole and get inside the room. How does it rise to the top if the floor is poorly waterproofed? The fact is that whether it is concrete, brick or building block, all these materials have a very bad property - to absorb moisture. The base, for example, can lift moisture from the ground by almost a meter. This is why waterproofing between the wall of the house and the base is so important.
How to fix: In this case, you have only one way out. Find the place through which water gets inside the wall, and do better waterproofing, or insulate the base from the outside, if this is the case. Inspecting a house from the street will yield more results than looking for a solution from the inside. And of course, ventilation or frequent airing of the room will in many cases reduce the likelihood of problems with wet walls.
This is a very common occurrence when the ventilation in the house is not sufficiently calculated or does not work well. Even if it is in good condition, there are still corners in the house in which it “does not work”, and over time they begin to sweat.
Signs: At common problem With ventilation, strong fogging of windows is possible. With localization, the wall in the house gets wet behind a curtain, or behind some objects that prevent air recirculation near the wall, while the rest of the walls are completely dry.
Why is this happening: If there is insufficient ventilation, no matter what you do, moisture will accumulate on the walls. In fact, there is enough moisture in the room for this, even if it seems that the air is dry.
How to fix: If there is a general problem with ventilation, it is necessary to solve it. There must be circulation in the house. If there is a local problem in certain places, remove objects that interfere with circulation.
If everything was fine before the renovation, but immediately after the renovation the walls in the house suddenly become wet, then there is nothing to worry about and this is a common occurrence.
Signs: The windows in the house sweat a lot.
Why is this happening: When you make a major repair using plaster, putty or other materials that contain water, the walls begin to absorb this moisture and this cannot be avoided. The repair is complete, everything seems to be dry, but the moisture in the wall will remain for some time in any case. In addition to this, if you did not ventilate the room enough during the renovation, a huge amount of moisture will be in the air.
How to fix: During repairs, it is necessary to ventilate the room, and in the cold period it is also necessary to heat it sufficiently. In this case, the walls will soon dry out.
Regardless of where the moisture on your walls came from, you must remember that it is highly undesirable to start this process, and the sooner you find the source of the problem, the easier it will be to correct the consequences.
Apartment owners quite often encounter such a problem as a wet wall in the apartment. This problem especially often occurs in winter, when the temperature difference between the outside and inside the room is very large and condensation begins to settle on the walls of the building. The question automatically arises, what to do if the wall in the apartment is wet and how to get rid of this problem. If you neglect to correct the situation and leave everything as is, then it is quite possible that black mold will subsequently form on the walls, which is extremely dangerous to human health, provokes respiratory diseases and causes serious complications.
In this article, readers will be able to find out why there are wet walls in the apartment and if the wall in the apartment becomes damp, what to do and what actions to take first.
Before you begin to solve the problem, you should answer the question why the walls in the apartment get wet and at what stage the damage is. If the degree of wall moisture is very high, then you will need to take radical solution, and, without delay, correct the situation as quickly as possible.
The first sign that indicates that the walls in the apartment are getting wet is that its surface becomes damp, 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 correct method remedy the situation, including the necessary equipment and materials that will be used. The main reasons why the walls in an apartment become very wet are the following:
Having figured out why the wall in the apartment gets wet, we found out that there can be several reasons for the occurrence and development of such a situation. Accordingly, to answer the question of what to do if the wall in the apartment is 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 will be required. It is enough to ventilate the apartment well and keep the windows open for a while. If repair work is carried out in winter, it is worth providing heat in the apartment so that the moisture remaining after the repair evaporates. If the heating is good, then batteries are sufficient for this purpose, but if they cannot cope, then you will need to turn on the heater.
If there are problems with ventilation, if the wall in the apartment is damp, only an experienced craftsman will tell you what to do, although initial stage can be dealt with difficult situation on one's own. It is enough to remove objects that interfere with quality air ventilation. For example, if moisture accumulates on 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 in an apartment become damp in the absence of good ventilation can be solved comprehensively. You will need to check all the ventilation openings that are located inside the apartment and ventilate the room more often. Additionally, it is worth installing a hood in the kitchen to remove excess moisture.
As we have already noted, the reason why a wall in an apartment gets wet may be the lack high-quality waterproofing. This problem It’s already more serious and it’s not easy to cope with it. There can only be one solution here - to sufficiently insulate the wall surface. As a rule, if the walls of an apartment become wet, it means the seams are outside the buildings fell into disrepair. What to do when the walls in your apartment get wet? in this case, only a specialist can advise. This will require serious intervention, since ordinary ventilation cannot solve the problem.
What to do if wet walls appear in your apartment in winter? This question concerns many home owners who are faced with such a problem. Moreover, if you take independent action in this case, you can only worsen the situation. Many people do not have the opportunity to perform additional insulation with outside buildings and, by 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 accumulate under the insulation into a puddle. It is extremely important to understand here that even if the owner of the apartment is an experienced climber and builder, you should not carry out insulation work yourself, but it is best to trust experienced craftsmen and who will do all the work to the highest possible quality.
For a more complete idea of what to do when a wall in an 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.
If the walls in your apartment are damp, what should you do? We try to figure it out in this article. Several options for correcting the situation have already been proposed, however, the most correct thing would be to contact specialists who can certainly fix the problem. If, however, it is possible to produce renovation work to eliminate the reason why there are wet walls in the apartment, it is worth preparing in advance necessary tools. The list of mandatory items includes the following names:
At this point, the list is not complete. It is likely that other devices and tools will be required to carry out special work. Here, each performer determines the tools independently, taking into account the specifics of solving the problem. In addition to tools, you need to take care of purchasing special materials, which are presented on construction market. Next, we will consider some of the nuances of insulation and waterproofing.
To answer the question of what to do when the walls in the apartment get wet, we can suggest strengthening 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 insulation is carried out both outside and inside.
Unfortunately, it is almost impossible to carry out such work on your own. This option is suitable for free-standing buildings, first floors, as well as buildings where there is no need to climb to a significant height to complete the finishing.
It is extremely important to choose the right thermal insulation materials, which are presented on the construction market in large quantities. To carry out the work, it is best to choose trusted manufacturers who pay attention to high quality characteristics materials. It is important to remember here that even if wet walls appear in the 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 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 correct execution work will give a guaranteed high-quality result. In this case, it is worth paying attention to two important parameters:
Only taking into account all these points can you achieve a significant reduction in humidity in the apartment and return the wall original appearance. To answer the question why there are wet walls in the apartment and what to do if the wall in the apartment gets wet, just study theoretical aspects this issue and contact a specialist for practical advice.
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, the problem here can be solved quite easily. You only need to insulate the foundation. This action This is especially true for those who are interested in giving their homes increased sound insulation. This will not only solve the problem of a wet wall indoors in the apartment in winter, but will also get rid of noise and unpleasant sounds.
Here it is worth giving preference to materials that have a high noise absorption coefficient, since this will save time on repairs and installation of sound insulation. The flammability class of materials is extremely important to eliminate the possibility of sudden fire. The best option may become a G1 class material, since the thermal insulation, even during combustion, does not provoke the appearance of a source of open flame. It is worth highlighting several of the most common insulation and at the same time soundproofing materials. The list of the most famous includes the following:
Many apartment owners are interested in the question of where to go if there is a wet wall in the apartment and what to do in such cases. In fact, there can be only one solution - to visit construction company, which provides similar services. This will immediately provide several advantages. 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 high-quality work that will not require rework in the future. Another important point is that the master has an idea of what to do if there is a wet wall in the apartment, which means he will do everything necessary work strictly according to technology. For example, we can give the following algorithm for finishing a section of a wall.
Most simple option wall insulation, which determines what to do when the wall in the apartment becomes damp is to insulate the surface from the outside using special “warm” plaster. The material is applied to plaster mesh and then decorated.
This option remains the only one when the homeowner does not know what to do when the wall in the corner apartment becomes very damp and where to turn if there is a wet wall in the apartment. 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, you should choose insulation taking into account custom 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 polystyrene foam, since it can easily ignite and thereby threaten the lives of residents.
The entire insulation process takes place in several stages. Each stage is extremely important for the overall result, since it allows the finishing to be completed with the highest possible quality and with the expectation of long-term use in the future. The algorithm of actions in this case is as follows:
If you have no idea what to come up with when the wall in your apartment gets wet, then we recommend that you contact experienced craftsmen who will as soon as possible will do everything Finishing work and will save you from this problem.
