Dampness in the apartment ways to eliminate. Ways to get rid of damp indoors

Excessive dampness often becomes a diagnosis of private houses, urban skyscrapers and summer cottages. In the cold season, it manifests itself as mold on the walls and windows. Many owners begin and end the fight only with the fungus, because it has a sharp negative effect on the health of residents. At the same time, the root cause high humidity- is ignored, so the mold will soon return. Only an analysis of the situation and an integrated approach will help get rid of dampness.

Causes of High Humidity

In nature, there are several hundred types of household mold. The main factor in their appearance in a residential area is excessive dampness. The fungus forms in places with poor ventilation on surfaces prone to extreme temperature changes. In other words, if your house has a cold wall, a dark coating will appear in poorly ventilated corners, as soon as you turn on the heating system.

In high-rise buildings, mold can occur due to global disturbances in the air circulation system. Check the draft in your ventilation ducts with a regular match. Its weakening or termination occurs for the following reasons:

mistakes of builders at the stage of building a house;
illegal interference with the integrity of the channels of your vertical neighbors;
failure of parts of the system due to the old age of the house.

It is difficult to eliminate ventilation in a high-rise building. House management companies, as a rule, go for this only if a global restructuring or reconstruction of the building is planned. You will have to rely on folk remedies to eliminate dampness in the room. In the private sector, such problems are relatively easier to solve, because everything depends only on the owner.

Attention! On the first floors of multi-apartment buildings or in private houses, dampness may appear due to flooding of the basement by a burst of water supply, groundwater, or poor thermal insulation between the wall and the foundation. Mold forms at the bottom of the wall.

Step 1. Fighting fungal plaque

To get rid of dampness, you first need to identify and eliminate all fungal plaque on the walls. Delay can lead to the development of diseases. The spores of the fungus with air enter the lungs and disrupt the functioning of the respiratory system. Dampness and mold can cause acute respiratory infections, bronchitis, asthma and other respiratory diseases up to tuberculosis. In addition, it depresses the immune system. For residents of the house, especially children and the elderly, this is manifested in a deterioration in well-being, allergic reactions and exacerbation of various ailments.

Attention! A dark coating that has appeared due to dampness can not be immediately seen. But a strong moldy smell will immediately give away the problem.

In the process of cleaning, it is important not only to clean, but also to disinfect all surfaces where there is a fungus. Use any suitable means:

chlorine bleach and other chemicals;
vinegar;
hydrogen peroxide;
soda;
ammonia;
butter tea tree etc.

Attention! Wear gloves and a mask when handling any type of anti-moisture and anti-fungal cleanser.

It is important that spores do not get into your respiratory tract in large quantities during close contact. When using special store funds never mix one with the other. This may cause chemical reaction with dangerous consequences for you. The video will help you understand in more detail how to deal with mold and dampness.

If the mold has extensively covered the surface of the wallpaper, get ready to rip it off the wall. The mycelium of the fungus is under the paper layer. There are no means to kill him without damaging the wallpaper itself. In this case, the plaster will probably also have to be removed. First, thoroughly clean the surface of the fungus, and then treat with an antiseptic. For example, aqueous solution stationery glue (1:4) or urea. Before any further work to get rid of dampness, the wall section must dry completely.

Advice. For the effective action of the disinfectant, heat the cleaned walls to +50 ° C.

Step 2. Finding and eliminating the root cause of dampness

Diagnosing the problem is the key to getting rid of dampness. Take the glass, press it against the wall and fix it in that position. After 2-3 hours, remove and check the surface:

dry - a source of humidity indoors;
damp - dampness penetrates from the outside.

The second case is easier to understand. Your task is to reduce the temperature difference, from which the walls suffer due to dampness. There are two ways to do this. Better to use them in combination.

Thermal insulation of the wall. Cover it with breathable insulation material. Today many choose external insulation, but experts advise first of all to carry out work inside.
Check and, if necessary, upgrade the heating system. Perhaps it is cluttered or not powerful enough to warm and protect certain corners of the house from dampness.

Advice. Often, large-sized furniture becomes the cause of the formation of harmful plaque if it interferes with the normal ventilation of the wall adjacent to the street. Engage in rearrangement.

Folk ways to get rid of dampness due to poor ventilation:

Place bags of sugar or salt.
Place small containers with potassium chloride in the corners.
Heat up and lean the bricks against the wall. Repeat until the surface is free of moisture. Use 1 brick no more than 3-4 times, then it should dry out.
Treat the wall in 2-3 layers with decoction laundry soap(Bring 100 g/l to a boil and refrigerate). After drying, apply with a brush the following solution: 100 g of alum in 6 liters of water.

Attention! Do not use sprays or other antifungal agents, and air conditioner to dry at home.

You can get rid of dampness only by accurately determining its cause. When you eliminate the fungus and moisture, do not forget about further prevention.

How to deal with dampness in a room: video

For a comfortable stay in a residential area, it is required not only to make quality repair and tastefully place interior items. It is also necessary to maintain the necessary state of the internal environment, that is, the microclimate. Excessive humidity in the apartment, turning into dampness, can harm not only the people living in it, but also the decor and finishing materials.

Reasons for high humidity

Permissible humidity indicators in residential premises should be in the range of 30 ... 60% (in accordance with GOST 30494 * 2011).

GOST in the current edition. Buildings residential and public. The parameters of the microclimate in the premises. PDF file.

Before taking measures to eliminate dampness in the apartment, it is necessary to determine the causes of its occurrence. Otherwise, the measures taken may not have the desired effect.

In the vast majority of examples, an increased level of humidity in a dwelling is caused by the following reasons:

The ventilation system must ensure the supply of fresh air to the apartment, which is necessary to create a good microclimate, and the removal of polluted air. Periodic ventilation will not be able to fully cope with this task. ventilation ducts can be blocked by the owners themselves, or the owners of other apartments are the culprits of the problem.

Often it is not possible to quickly determine leaks in communications due to the installation of boxes that mask them. Upstairs neighbors can also flood.

You can also determine the source of the problem by the location of the mold that has appeared. A biological lesion that has spread throughout the wall in contact with the street indicates poor thermal insulation. Mold in the upper part of the wall indicates the need to check the tightness of the interpanel seam.

If mold has appeared at the bottom of the walls in an apartment located on the lower floor, there is a possibility of poor waterproofing from moisture coming from the basement or an error in the construction of the foundation. Of course, the problem with this load-bearing structure unlikely to be resolved. But it is possible to significantly reduce the dampness that appeared due to shortcomings in the insulation of the room from moisture penetration. To do this, it is recommended to take up the device of floor waterproofing. Required materials mass produced today.

It will not be possible to solve the issue of moisture penetration from the roof by carrying out measures for waterproofing the ceiling. The roof needs to be repaired.

If the cause of dampness in the apartment is a leaking roof, basement flooding, poor thermal insulation or leaky seams between the panels, you should contact management company.

The level of humidity in the apartment can be affected by linen hung out to dry, and an installed volumetric aquarium, and a large number of indoor plants, and the contents of the containers boiling on the stove. However, these factors have either a short-term or insignificant effect.

The source of the smell of dampness in the apartment can be washing machine. The reason is clogging of some parts of the unit, long-term storage of dirty laundry in the tank, dirt remaining at the bottom of the drum, etc.

Any of these problems can lead to dampness in a certain place in the apartment. Having found out the cause and taking timely measures to get rid of the misfortune, you can quickly eliminate the consequences to which this phenomenon leads and restore the optimal microclimate in the room.

Interesting! Of course, a hygrometer helps to determine the value of humidity in the room. However, you can conduct an experiment by connecting children to the event. To do this, you need a glass of water, which is placed in the refrigerator for a couple of hours (it is necessary that the water temperature drops to 3 ... 5 degrees). After that, the vessel must be installed in a place where there are no devices nearby that regulate the microclimate. If, after ten minutes, dripping drops of condensate appear on the walls of the glass, the humidity in the room exceeds the optimal values.

Factors indicating a problem

It is possible to determine a significant excess of the humidity level in an apartment not only with the help of a special device, but also visually.

Mold and fungus appear on the ceiling or walls. Microorganisms multiply at lightning speed in a closed space with a moisture content in the air exceeding 70% and a temperature environment greater than 18 degrees.

Symptoms of dampness are also problems with the condition of the finish: plaster may collapse, rot wooden materials or fall behind the walls of the wallpaper.

Condensation appears on plastic windows. The reason can be both a factory defect in the structures, and problems with the microclimate in the apartment.

In addition to the listed problems from dampness in the room, for those in the apartment, an unpleasant smell will also provide discomfort, which cannot be eliminated with the help of any air fresheners.

What is dampness in a room?

As already noted, high humidity leads to damage to finishing materials and interior items. Particularly affected are products made from paper, wood or leather. Can even deform door blocks, fall into disrepair paintings and books. All this leads to the need for repair work.

But most importantly, dampness can cause irreparable harm to the health of households. The main dangers are young children and elderly residents. Spores of harmful microorganisms lead to exacerbation chronic diseases. Once in the respiratory system, they cause allergic reactions.

Much more often, apartment residents suffer from colds, and they occur in a more acute form. Damp textiles in contact with the body contribute to the development of rheumatism.

Staying at the apartment becomes uncomfortable. People experience reduced concentration, fatigue, and performance problems. An unpleasant smell emanating from clothes also does not add positive emotions. Finally, food has a reduced shelf life.

How to deal with moisture

Having diagnosed the problem that has appeared, it is necessary to immediately begin to eliminate the cause of the dampness that has appeared. If you can eliminate the source of danger on your own, you should do repair work. Otherwise, you need to contact the management company to solve problems with waterproofing, insulation and ventilation of housing.

It is also necessary to comply simple rules to maintain an optimal microclimate. It is important to periodically ventilate the room, as dampness does not tolerate fresh air.

An excessive number of indoor flowers should not be installed in the room, watering which also leads to a violation of the microclimate.

The room most prone to dampness is the bathroom. To prevent this from happening, you need:

Important! Before processing the joints with sealant, a disinfectant should be applied.

Humidity reduction technology

Dehumidifiers help remove excess moisture from the surrounding air. Devices have different principle action, power and performance. They are placed on the floor, on a table or hung on a wall. For domestic use suitable models that can extract from the air from 10 to 20 liters of moisture per day. It is more convenient if the device is equipped with a built-in sensor that allows you to adjust the humidity in the room in automatic mode.

Prices for the range of air dryers

In the kitchen, where intensive steam generation takes place, you can not do without forced ventilation, for which they are installed there. The most demanded equipment has a capacity of 400 ... 600 m 3 / h.

Problems with high humidity sometimes it turns out to be solved by installing . Poor heating during the cold season often leads to dampness.

After the cause of dampness is found and eliminated, it is necessary to take measures to eliminate mold and fungi. Masking the problem area with the help of finishing cannot be limited. Dangerous microorganisms must be completely eliminated.

Elimination of mold on walls, floors and ceilings

Getting rid of mold is not easy.

Work technology.

Step 1. Foci of biodamage in the apartment are determined. It is important to provide access to all problem areas: move interior items, remove carpets or curtains, etc.

Step 2 During the event, it is necessary to use protective equipment, since many compounds are quite toxic: gloves, respirators and goggles.

Step 3 A rough brush eliminates a colony of microorganisms. To get to the base, you often have to shoot finishing material: wallpaper, plaster, drywall, etc. Moreover, it is necessary to clear a larger area so that it is possible to kill spores that have not had time to manifest themselves.

Step 4 The infected area and the area around it are being treated with the help of fungicides or antiseptics, which are presented today in a large assortment. The compositions are applied with a roller, brush or spray gun. Reapplication may be required depending on the manufacturer's recommendations. After that, the surface should dry.

Not every one of us pays attention to the level of humidity in the home, but it is this indicator, along with air temperature and illumination, that is involved in creating a microclimate and directly affects well-being. Both low and high humidity are harmful.

Optimal values. If you focus on sanitary norms, then normal level relative humidity for living quarters varies from 40 to 60%. In winter, when hot radiators dry up the air, the humidity “drops” to 15-20%, air humidifiers come to the rescue. But in warm time years, indicators often “go off scale” in reverse side, which leads to unpleasant consequences.

Effects. The negative impact of high humidity on the human body is not exaggerated. First, heavy wet air contraindicated in people with cardiovascular diseases, hypertensive patients and asthmatics. Secondly, in combination with elevated air temperature (more than 25 ° C), high humidity provokes overheating of the body, and if the temperature is lowered, hypothermia.

In such conditions, harmful microorganisms and bacteria multiply with amazing speed. Even in healthy adults, breathing is disturbed, efficiency decreases, allergic reactions occur, to say nothing of the “risk zone” - the elderly and young children.

High humidity leads to mold

In addition, high humidity in the apartment contributes to the appearance of mold and fungus on any surface, it can ruin furniture, books, bedding and mattresses, food (cereals, flour, vegetables). A persistent "swampy" smell appears in the house.

How to measure humidity level

At home, a hygrometer is useful. This device, more like a digital alarm clock, controls the increase or decrease in humidity.

Hygrometer - the simplest device for measuring humidity

However, you can find out whether the humidity is increased or not using plain water. Fill a transparent glass halfway and place it in the refrigerator for several hours (“outlet” water temperature should be no more than 5 ° C). Place the vessel in the “tested” room, away from household appliances and radiators, watch for 5-10 minutes. Large drops of condensate appearing on the walls of the container indicate that the humidity in the room is high.

Large drops are a sign of high humidity

How to deal with high humidity

First of all, you need to find and fix the problem. The following options are possible:

1. Non-working ventilation. Hoods tend to break, and ventilation shafts become clogged. And if in the warm season you can open the window to ventilate a room or kitchen, then in winter it is problematic to do so. Be sure to check the ventilation of the apartment or house. If necessary, install a hood in the kitchen, more powerful fan Or a baffle in the bathroom.

2. Insufficient insulation or waterproofing. Poorly insulated and not waterproofed walls and floors, like a sponge, absorb moisture from the outside, becoming covered with condensate and "giving out" all this into the room. Constantly wet wallpaper or “chunking” linoleum is a reason to do repairs.

3. Lack of heating. The rooms that are heated to a minimum dampen most quickly. Installation additional radiator or buying an oil heater solves this problem.

4. The presence of sources of moisture. Perhaps the most common reason for high humidity in an apartment: poor quality installed double-glazed windows collecting condensate, errors when connecting a washing or dishwasher, leaking pipes or plumbing. "Walk" through all nodes and connections, if necessary, replace or repair problem areas.

Not right installed windows- the most common reason

If in an apartment, process the glass special composition: 5 parts clear dishwashing gel or liquid soap, 3 parts glycerin, 1 part turpentine, and then rub them to a shine with a clean rag.

Prevention of high humidity

Elementary, but effective preventive measures will not be superfluous even when everything is in order in the house with humidity.

Be sure to ventilate the apartment (even in winter) at least half an hour a day.
Heat the rooms evenly, preventing the already heated air from entering the "cold" room, creating a sharp temperature drop.
Do not dry clothes in the living quarters and bathroom, it is best to do it on the balcony or loggia.
Use simple but effective absorbents. Arrange in cabinets, on shelves in the toilet, bathroom, kitchen bags with table salt, rice, coffee beans.
Run the dehumidifier periodically. This unit passes excessively humid air through filters, which helps in maintaining a natural and healthy microclimate.

An example of an electric dehumidifier

Dampness and high humidity in the house, especially in some of its places - many people face this problem. The reason for this may be poor ventilation, the constant presence of water, Construction Materials that were used in the construction of the house.

Dampness and high humidity in the house, especially in some of its places - many people face this problem.The reason for this may be poor ventilation, the constant presence of water, building materials that were used in the construction of the house.

As a result, we notice black spots on the walls and in the corners, the paint that paints the walls or some objects often deteriorates.

5 effective remedies for dampness

And, of course, dampness in the house is also harmful to the health of the people living in it. She creates favorable environment for fungus and bacteria, for ticks. Because of this, a person often develops allergies and diseases of the respiratory system.

Fortunately, there are different facilities natural origin , which help to neutralize the increased humidity in the house.

1. Soda

Baking soda is known as a good natural deodorant, as an antibacterial and bleaching agent. She is also one of the best means to combat high humidity in the house.

The absorbents included in its composition help get rid of mold, neutralize bad odors and clean walls from dark spots.

Mode of application:

Put those bags of salt in closed spaces which you want to protect from moisture, for example, in cupboards.
After 2-3 weeks, replace them with new bags of salt and lavender oil.

3. Borax

Borax (sodium tetraborate) has become very popular in last years. It is not as aggressive as bleach and, thanks to its anti-fungal action, helps to remove mold from walls and tiles.

Ingredients

1 tablespoon borax (10 g)
5 cups water (1250 ml)

Cooking

Put on rubber gloves and dissolve borax in water.

Mode of application

Spray the areas you want to remove mold with this solution. Let it act for 30-40 minutes, then remove its remnants with a napkin.
Repeat this procedure at least once a week.

4. White Vinegar

White vinegar, an environmentally friendly product with antibacterial properties, is used in household to solve different problems.

Thanks to the natural acids it contains, it inhibits the growth of mold on walls, neutralizes bad odors and reduces humidity.

Vinegar also helps clean tubs, toilets, tiles, and other wet surfaces.

Ingredients

½ cup white vinegar (125 ml)
¼ cup water (62 ml)

Cooking

dissolve white vinegar in water and pour this solution into a spray bottle.

Mode of application

Shake the solution before use. Spray them dark spots and mold spots.

Do this 2-3 times a week.

Do you notice signs of high humidity in your house, mold and feel bad smell? Then prepare one of the remedies that we have listed, and get rid of mold and moisture before they become the cause. serious problems with the health of you and your loved ones.

Dampness in rooms is fraught with bad smell, black spots and mold on the walls and in the corners. Wet warm air is an incubator for bacteria and microscopic fungi that cause various life-threatening diseases: tuberculosis, colds, bronchitis, pneumonia, bronchial asthma, skin inflammation and suppuration. Dampness from the room must be removed using various methods.

Isolating source of moisture

If dampness comes along the wall from the soil in the form ground water, the room is difficult and sometimes impossible to drain. A similar situation arises with poor-quality waterproofing of the foundation. The way out will be drainage system installed in the area adjacent to the building. If this is not possible, the damp wall is insulated by covering it with a layer of waterproof material:

rolled bitumen;
mastics;
penetrating mixtures based on polyurethane resins.

The latter method is preferable. Under a layer of bitumen, the wall continues to dampen and collapse. Penetrating mixtures penetrate into the pores, making concrete and brick waterproof.

Damp basements

On the first floors elevated humidity appears due to basement flooding premises . The housing office should deal with the elimination of pipe breaks, but the owners of apartments on the lower floors can also participate in improving the microclimate by additionally waterproofing the floors:

floor slabs are cleaned of dirt and outgoing layers of concrete;
close up cracks;
equalize and prime the surface with bituminous or any other water-repellent mastic.

The insulation should cover the floor and partially the walls, rising vertically on them by 10-20 cm.

Easy to use neutral sealants:

Penetron - mortar from cement and quartz sand, which is suitable for waterproofing reinforced concrete and concrete surfaces.
Waterplug is a product made of aluminate cement, sand and active chemical additives. It is applied for fast elimination leaks in concrete, brick and stone surfaces.

The premises on the first floors need additional heat sources. They can become:

Sun rays;
split systems;
floor heating systems;
domestic electric heaters.

Additional sources are used in spring and autumn, since the humidity in basements intensifies sharply at this time of the year. Heat quickly drives dampness out of the room.

Drying methods

The fight against dampness is successful when the root cause is eliminated. Dehumidification will last a long time if you get rid of the source of the problem.

For example, if a wall becomes damp due to defects in pipes adjacent to it or as a result of inaccurate use of water (flooding), then to eliminate humidity in the room, it is enough to restore the integrity and tightness of the water distribution system.

How to maintain normal humidity in the apartment?

Alpine vents

Apartments on the upper floors are most often damp external reasons. Humidity appears as a result of insufficient wall insulation, poor-quality processing of interpanel seams, poor roof waterproofing, low battery efficiency central heating.

Ventilation of apartments located on the fifth floors of Khrushchev buildings provides for the supply of fresh air through slots in window frames, and then its removal through the ventilation shafts. Most tenants eventually change their old wooden frames on plastic double-glazed windows that prevent the inflow outdoor air. Also the ventilation upper floors the five-story building is not working efficiently enough, since the lower levels "pull" the main air current in the mines. As a result, mold in the corners and water on the window sills have become commonplace for apartments located under the roof.

Alpine vents help solve the problem of insufficient ventilation of Khrushchev and other panel houses. Holes for these structures are punched in the outer walls. The dampers supply fresh air, which passes through the room and is removed through ventilation shaft by taking in moisture.

Alpine window device

Alpine window - view from the room

Electric dehumidifiers

In rooms with poor ventilation, dampness appears even for ordinary household reasons. Daily drying of clothes, a large number of aquariums or plants, frequent cooking or showering can increase the amount of water vapor in the air to a concentration that is unacceptable for a living space.

For this reason, it is necessary to reconsider life. Linen should not be dried in rooms, but on balconies, verandas, loggias, attics. A range hood mounted over the stove will eliminate the fumes rising from boiling pots and kettles. An electric towel warmer for the bathroom will help fight moisture in this room.

It is most reliable to eliminate the high humidity of the air in the apartment not with your own hands, but to purchase a special dehumidifier with automatic mode work. This kind climate technology successfully copes with the elimination of humidity in apartments, quickly adjusting the state of the air. Household dehumidifiers are economical and compact, operate silently, and are safe to use.

Household electric dehumidifier

The principle of operation of the device is as follows:

fan sucks room air inside the device;
it passes through the evaporator and cools below the dew point, while the water vapor condenses and flows into the tank;
air is passed through the condenser, heated and returned to the room.

It has a higher temperature than the original, so it is undesirable to use the device in hot weather. AT warm season use another method of dehumidification - ventilation.

Airing

Airing in sunny, dry weather helps to get rid of slight dampness and is a good prevention of its occurrence. There are sanitary standards for this procedure for various institutions, including preschool and educational institutions.

Residential rooms ventilate before going to bed and after waking up, opening window or window leaves for 10-30 minutes. In the bathroom (if it has a window), the doors are pre-closed so that dampness does not spread to other rooms. The apartment is aired after long cooking, showering, washing. If the room is to dry clothes, the door to it must be tightly closed, and the window must be thrown open.

Additional heating

Heaters raise the temperature and dry the air at the same time. This function is performed by central heating batteries. If the power of the radiators is not enough, install additional sources heat. They will reduce the relative humidity of the air. At the same time, water vapor will not leave the room without ventilation, but dampness will become less noticeable.

For heating with dehumidification, the following heaters are used:

infrared;
oil;
convector;
fan heaters.

Exist heating appliances, which can really remove moisture from the air, dividing it into oxygen and hydrogen atoms. Under normal living conditions, it is impossible to achieve such an effect, since a temperature above +2000 degrees Celsius is required. It is typical for special hard-alloy heating elements. In apartments, cottages and dachas such high temperatures flammable, so they can only be used in industrial environments.

Folk ways

In summer, wallpaper is removed from moldy walls and treated as follows:

Dissolve 500 g of laundry soap in 5 liters of water.
Boil, let cool.
The solution is evenly covered with a wall using a brush.
Let dry.
Repeat until the solution is no longer absorbed.
Another composition is prepared - 100 g of alum is diluted in 6 liters of water.
Cover the wall once.

There is a way to eliminate dampness in a private house with furnace heating. To do this, new bricks are heated, laid on fire-resistant stands near a damp wall. The operation is repeated until the dampness disappears. Bricks stop absorbing moisture after 10-15 incandescences, then they are replaced with new ones. The old ones are used as fireproof coasters. Red-hot bricks should not be left overnight to avoid a fire. There should be no combustible objects near them. The method is not used in houses with wooden walls: from timber, logs or boards.

Table salt absorbs moisture from the air well. To drain the room in a damp corner put any open vessel with substance. From time to time, damp salt is dried in the oven, crushed and used again as a moisture trap. Instead, you can use other folk remedies: calcium chloride (they sprinkle roads on ice), quicklime, charcoal.

Mold on the wall of a damp room is removed as follows:

the surface is well dried;
one part of salicylic acid is dissolved in 200 parts of alcohol and diluted with a small amount of water;
lubricate mold spots with a mixture.

Salicylic acid and alcohol will keep the fungus from multiplying in the old place, but it can appear on another wall if measures are not taken to drain the entire living space.
