Humidity in the house is a common phenomenon; it is formed during washing, cleaning the room, when washing and during cooking. But in some houses it is within the normal range, and in others it is increased, in which case the question arises: “why does high humidity appear in the house and how to prevent it?”
When there is an excessive amount of it, windows, glass and mirror surfaces fog up, stains appear on the walls, often with a touch of mold, all this is accompanied by a musty, unpleasant odor. What should the humidity level at home be without causing problems? 30-60% is considered the norm; it is measured with a special device - a hygrometer. In addition, you need to remember that even normal indicators can various reasons change and keep normal level Humidity is quite difficult, especially in the summer, since in winter the air is dried by heating devices.
Of course, every owner who is faced with this problem wants to know how to get rid of humidity at home, because it causes a lot of inconvenience and, in addition, spoils aesthetic appearance dwellings. Due to constant dampness, fungus can form on walls, ceilings and corners, which is dangerous to human health; it causes chronic colds, allergies and bronchial asthma. Children are most susceptible to changes in humidity, their immune system suffers from this, and it also has a detrimental effect on the home.
How to get rid of humidity at home?
Dampness in a house can be influenced by many factors: weather conditions, the proximity of large bodies of water, building a house on a site with high flows. groundwater, poor ventilation and not regular airing of rooms.
To protect the house from high humidity, a mass was invented good ways, but in order to achieve maximum effect and eliminate this problem forever, you need to use these methods in combination. Naturally, such measures will require certain financial costs, but they will soon pay off, since they will help to avoid repair work and drug costs.
Humidity level in the house
Before you start fighting dampness, you need to determine the humidity level. As mentioned above, the humidity level in the house should be from 30-60%, a level of 45% is considered the most optimal. Once you are convinced of its excess, you can begin work to eliminate it.
The most effective way would be to carry out repair work in a damp room and carry out waterproofing. For example, for waterproofing basements, dry mortar based on cement. The bathroom floors are waterproofed using liquid glass. In addition, the external walls of the home are treated with plaster with cement base, and you need to make several such layers. You can “dress” the walls in a special protective water-repellent coating. These measures will prevent moisture from entering the house.
To reduce air humidity, modern dehumidifiers are used, which are divided into household and industrial. Household ones are used in residential premises; they are very compact and lightweight, so they can be moved from room to room and installed in any suitable place. Such devices are silent and easy to use.
A good option for eliminating the problem would be heating devices, especially in autumn and summer, when dampness outside increases the humidity in the room more than ever. Their frequent use during this period of time will dry out the damp air and prevent the formation of mold. But on the other hand, if the home is already heated, such devices can be harmful to health. Today on store shelves you can see a large number of chemicals that eliminate high humidity. They effectively combat this problem, but only last for a certain amount of time.
The reason why high humidity appears in the house is greatly influenced by modern double-glazed windows, or rather by their poor-quality installation. In order for air to circulate properly in the room, windows must be installed above heating devices, batteries, this prevents the glass from freezing and moisture appearing on it. Extra objects on the radiator or a very large window sill sometimes interfere with heating the window glass. In the first case, you should get rid of the interfering object, and in the second, you need to make holes in a large window sill. Sometimes the reason lies in the glass unit itself, which may be defective and have a defect. The company that installed the window incorrectly is required to solve this problem.
Often, increased humidity is caused by frequent drying of laundry indoors or faulty pipes in the bathroom, poor ventilation or its complete absence. To eliminate dampness, you need to check the pipes and, if necessary, replace them with new ones, check the ventilation system. Whenever possible, laundry should be dried outside. It happens that things that are not dried enough after washing end up in the closet, this also leads to dampness and the appearance of unpleasant odor. Therefore, it is worth drying your laundry as best as possible, preferably in the fresh air.
Oddly enough, too wet soil in houseplants can also contribute to dampness. You cannot water plants frequently and abundantly without allowing the soil to dry out properly.
How to reduce humidity in the house?
To the question “how to remove humidity in the house?” there are a lot of answers, the most important thing is to identify its cause, and then choose the most the right ways to eliminate it.
High humidity is typical for older residential buildings, in need of major repairs. All of the above measures to eliminate it in in this case won't help. There is only one way out - to do complete renovation dwellings using wood and plasterboard, which are natural materials. Drywall is famous for its ability to absorb excess moisture, and if necessary, on the contrary, highlight it. Therefore, it will serve perfectly for regulating the humidity in the room.
But still, how to reduce humidity in the house if its level has exceeded all permissible standards? The simplest and effective way There will be frequent ventilation of the room, especially after cooking, washing and water procedures. In summer it is better not to cover the windows with curtains, then Sun rays dry the rooms faster. An excellent device that dries the air is a fan, traditionally used to cool it. It is impossible not to mention the modern household appliances to reduce humidity. These include expensive air conditioners, special hoods, and simple appliances. affordable price. Such devices absorb excess moisture in the air to an optimal level, protect the house from mold and mildew, provide the premises with dryness and warmth, as well as a pleasant smell, which is also important.
How to reduce humidity in the house?
There are other methods to reduce humidity in your home. These are effective chemicals, produced on the basis of absorbents, moisture absorbers. During their use excess moisture falls into the tank. These medications can be used as needed.
If there is no ventilation in the house, its installation will be required immediately. This work can be done by the owner of the apartment himself or by inviting a specialist. A through hole is made in the wall of the problem room, which is closed with a grill both inside and outside. A recuperator is pre-installed between the grilles; it will draw raw air from the room, leaving heat in the room.
Sometimes desiccant tablets can help solve the problem; they can be found in hardware stores.
Before reducing the humidity in the house to the desired level, you should find the cause of its occurrence, eliminate it and use tips to prevent its recurrence.
In the process of dealing with dampness, many people forget that excessive dry air is no less harmful to human health, therefore the main task– do not overdo it and “adjust” the humidity to the optimal level.
Everyone dreams of a cozy and comfortable home. But even the most modern apartments are not immune from the appearance mold fungus due to too high indoor humidity levels. You can cope with the problem with the help of effective traditional methods and industrial products.
Causes of dampness
The normal level of humidity in an apartment is no more than 60%. During the hot summer, this figure can be reduced to 45%. It is under such conditions that a person will feel as comfortable as possible. But if it is high, optimal conditions for the development of dampness, and therefore fungus.
High levels of indoor humidity can cause fungus
The reason for the increased level of air humidity in residential premises may be:
- poor ventilation;
- damage water pipes and improperly installed home plumbing;
- regular drying of laundry in residential areas;
- frequent bathing;
- the presence of aquariums and a large number of indoor plants in the apartment;
- not insulated inter-wall seams and cracks.
High humidity is also generated during the cooking process. To eliminate this problem, it is often enough to ventilate the room well. But if the ceiling is leaking, getting rid of the dampness will not be so easy.
The appearance of condensation indoors in summer and winter is also facilitated by the installation of plastic windows.
Where does mold appear?
Most often, mold can be found on walls and windows, on the ceiling and floor. Sometimes the fungus is hidden under carpeting, in the pile, behind wallpaper, furniture and decorative objects on the walls, as well as in cabinets and bookshelves. If mold is discovered, immediate action must be taken to prevent the fungus from reproducing and to completely remove it.

Instructions for reducing humidity in an apartment or private house
- One of the most simple ways One of the ways to effectively combat dampness in rooms is regular ventilation.
Good room ventilation helps remove excess moisture
- It is also necessary to take care to isolate sources of dampness. If a wall in a room becomes damp due to a problem with the plumbing or sewer pipes, it is necessary to take measures to eliminate damage, which will allow the wall to dry out over time. But if dampness in a private house occurs due to the proximity of groundwater, the only way to solve the problem is to insulate the walls and foundation with waterproof materials, which can be purchased in specialized construction stores. In some cases, it is advisable to organize additional heating of the room, which will dry damp corners and prevent further development fungus.
Additional heating of the room will reduce humidity and dry damp areas of walls and floors
- To find out the reason why the walls of your home are covered with moisture, you can use this method: attach to inner surface tape a plastic sheet 50 cm long to the wall; after a few days, remove it and check the condition of the surface underneath it. If it is dry, the cause of mold is high level humidity in the room. If it is wet, then the reason lies in water seeping through the wall. You can get rid of this problem using special water-repellent paints or plaster, which contains silicone or synthetic latex. To prevent dampness inside, these products are also applied to external walls. In some cases, it is advisable to carry out complex repair work.
Water-repellent paints and plasters will protect walls from fungus
- Owners of private houses should remember that earthen floors are excellent conductors of moisture. For this reason, it is advisable to cover them with polymer materials or concrete them.
Concrete floor does not allow excess moisture to pass through
- Cracks must be removed using solutions that harden upon contact with a moist environment. A plaster solution is used for the walls. When sealing defects located at the junctions of walls and floors, epoxy materials are usually used.
High-quality sealing of cracks will prevent the appearance of fungus in an apartment and private house
- Causes of excessive humidity inside wooden buildings- poorly caulked seams between logs and insufficient ventilation. You can cope with the problem by using special antiseptic preparations and bleaches that effectively remove fungus, for example, Bioshield, Neomid, Remmers or Prosept.
Sealing the seams between the logs and treating the wood with special compounds will prevent the appearance of dampness inside the house
- In apartments located in houses made of bricks, foam blocks and aerated concrete, with high levels of humidity, it is advisable to use dehumidifiers. Such devices are ideal for eliminating excess moisture in bathrooms, toilets and kitchens.
Air dehumidifiers will cope with excess moisture in any living space

Often unwanted moisture accumulates under linoleum. It is there that all the conditions are created for the development of mold, which is almost impossible to get rid of completely and the coating has to be changed. In this case, it is advisable to follow important recommendations:
- Under no circumstances should old materials be laid on floors affected by mold;
- the fungus often spreads to the walls, so you should cut off the lower part of the wallpaper adjacent to the baseboards;
- When installing new linoleum, it is advisable to treat it with antifungal drugs.
To remove fungus under linoleum, you need to change the floor covering
Fungus under the wallpaper
If mold has formed under the wallpaper, you need to clean the surface of black spots using one of the solutions:
- from washing powder and chlorine (1–2 tablespoons of chlorine and 30–50 g of powder) - dilute the dry mixture with 3 liters of cool water, not forgetting to use protective equipment in the form of gloves and a respirator.
- from ½ bar of laundry soap, 100 g of soda and 5 liters of water.
Armed with a few clean rags and a sponge, you should clean the walls and dry them using a household heater or infrared device. Then you need to apply antifungal drug, for example, Furacilin or Nystatin.
- Dissolve 4-6 tablets well in 0.5 liters of hot water.
- Add another 3–5 liters of water.
- Treat the walls of the room with the solution. Instead of these drugs, you can also use copper sulfate.
- Dry the surfaces thoroughly.
- Apply primer for wallpapering. When choosing a suitable composition, you should pay attention to products containing antifungal substances.
Mold on plastic windows
If mold has formed on plastic windows and slopes, action should be taken immediately.
- Remove visible fungal stains using an aqueous bleach solution in a 5:1 ratio.
- Treat windows with ready-made antifungal compounds (Vincents, TEKS, Polyline, Dufa) or those made independently.
You can make remedies at home using the following recipes:
- 0.2 liters of boric and 70% acetic acid per 1 liter of water;
- 100 g of sodium fluoride and copper sulfate for 1 liter of water;
- 100 ml of copper sulfate and household bleach per 1 liter of water.
The selected composition must be applied to the surface plastic frames and slopes with a brush. To avoid the recurrence of mold, it is recommended to use rubber-based waterproofing mastics. Using such means, you can provide surfaces with a waterproof coating.
Don't forget about protective equipment - gloves and a mask. After completing the treatment, ventilate the room for 40 minutes.

Mold in the bathroom
If mold appears in the bathroom, you also cannot do without treating surfaces with antifungal compounds. If fungus has formed on the ceiling, it should be removed along with the plaster, removing sealant and paint from the affected areas. After completing the work, it is necessary to make sure that the pipes and faucets are not leaking, and to eliminate any damage. The joints of plastic parts can be treated with sealant.

Home remedies to combat fungus and dampness indoors
In addition to industrial compounds, you can use effective and inexpensive home-made products to combat fungus.
- Take 0.5 kg of laundry soap, grate and dissolve in 5 liters of water.
- Boil the resulting mixture and cool it.
- In warm summer weather, brush several coats of soapy water onto moldy walls without wallpaper.
- Then cover them with a composition prepared from 100 g of alum and 6 liters of water.
You can deal with dampness using calcium chloride, placing it in the corners. To reuse it, it must be dried under the influence of high temperatures, and then ceiling. Charcoal and quicklime are suitable substitutes. However, when using this method, care should be taken to ensure that these substances are not accessible to children or pets.
Mold prevention
- To prevent mold growth, monitor indoor humidity levels using a hydrometer.
- Ensure good ventilation and sufficient sunlight.
- Use fans in the bathroom and kitchen, regularly check the draft in ventilation shafts, and monitor the condition of plumbing fixtures, especially at their connections.
- Seal cracks in walls and floors.
- When conducting overhaul use mineral-based materials that allow you to more effectively regulate the level of humidity in the premises.
- Take care of high-quality waterproofing.
- Inspect regularly plastic seals on PVC windows, check their suitability and replace them in a timely manner.
- At the first appearance of condensation, promptly eliminate the cause of its formation.
Simple and available methods will help eliminate excess moisture levels in the premises, thereby preventing the development of harmful fungus. When using a variety of products and formulations, do not forget about safety measures that can protect your health. Regular preventive measures will minimize the risk of mold reoccurring in your home.
Quite often, owners of apartments and private houses have to deal with the appearance of mold. In this regard, they want to find the most effective ways remove fungus at home. In this article we will tell our readers about what types of fungi can grow in a living space, the reasons for their formation, how to get rid of dampness in the house and what products are best suited for such purposes.
So how to deal with mold in the house? If you notice white formations in the corners or on the walls that look like cotton wool or fluff, you should immediately find the cause of the development of microorganisms. If you ignore this sign, after a while you will be able to see gray, yellowish, purple or pink shades appear on the surface. It will be very difficult to get rid of such mold in the future.
There can be several types of mold in the home.
The white house fungus actively destroys the structure of wood. It is capable of changing color, creating cracks, drying out the base.
Blue fungi. This variety is also often found on wood. Microorganisms can even destroy the structure of dense coatings that are applied to the surface wooden products– varnish, paint. After this, moisture will penetrate into the product itself. The colony of these fungi has a bluish gray tint.
Rotting fungus. This variety can be dry or wet.
The wet type will actively attack wood, which is usually located near the ground, sewer or drainage pipes. Such areas quickly become loose and rotten, on which dark elements appear. 
Dry fungus grows on walls and corners due to high humidity. A reddish-colored pollen will appear on the surface. The tree will be destroyed by gray stripes.
There is also black and white mold. It appears not only on wood, but on almost any surface - stone, tile, plastic, tile, glass.
Actinomycetes are spores that soften wood and cellulose fibers. Within a few years, this type of fungus can destroy a structure.
In addition to the fact that these pathogenic microorganisms are capable of destroying many various materials, they also negatively affect human or animal health. This is the reason why you need to know how to get rid of mold in your home. However, before you remove the fungus, you need to find out the reason for its appearance. This will help prevent further growth of mold after removing it.
Video “Fighting dampness”
From the video you will learn how to deal with such an unpleasant phenomenon as mold.
Reasons for appearance
First of all, owners should know how fungus appears in the house. Knowing the real causes of this problem, you can speed up the process of cleaning any surface, as well as prevent the appearance of pathogenic microorganisms in advance. 
The main reason for signs of mold to appear is dampness in the house. It is very difficult to fight the fungus, since its spores are found almost everywhere and spread very quickly. As soon as the development of microorganisms appears favorable conditions– mold will begin to grow on any surface: on the foundation, wood, plastic, tiles, wallpaper. Fungus on walls and ceilings is a common occurrence if the microclimate in residential premises is disturbed.
In rooms where moisture constantly accumulates and does not have time to dry, fungus will almost always appear. In wooden houses this can become very big problem, since the roof and base are made of wooden beam. If mold has grown there, then over time it can disrupt its structure, which will lead to deformation of the main parts of the building. Therefore, you need to quickly get rid of the colony of microorganisms.
The floor covering becomes damp very quickly, as do the walls. In general, dampness is often found in the lower levels of a home. If it is a multi-story building, then on the first two floors.
Such places are a very favorable environment for the development of colonies of fungi and toxic spores.
There is another reason why dampness appears - lack or poor ventilation of the room. IN small rooms often bred houseplants that require constant care and watering. If there is no access to sunlight or the room is not regularly ventilated, then mold will not be long in coming. Homeowners may also use humidifiers incorrectly. This is why mold appears on the walls of the house. 
Dealing with mold in your home can be a huge challenge as the spores will remain indoors all the time. For effective destruction Such microflora should be known how to get rid of dampness in the house.
How to get rid of under the floor in a wooden house?
For any surfaces or products that are made of wood, the appearance of fungus can be disastrous. How to get rid of dampness in a house if there are a lot of wooden elements in it?
Before looking for ways to destroy mold, you should determine the cause of its formation. In the new wooden house mold does not appear immediately, since the material itself for construction is used exclusively dry, and is also treated with special solutions and impregnation. This reliably protects the structure from mechanical damage and exposure to microorganisms. However, if you see damp material (for example, in an old attic or cellar). 
How to remove mold from wooden surface? Only by eliminating the real cause of its appearance will it be possible to completely remove mold from walls, ceilings or any other surface. Otherwise, the owners will encounter it again and again (possibly in new places).
Wet cleaning in this case will not be a sufficient measure. Removing visible and contaminated areas does not guarantee 100% results.
The first step is to remove the plaque that is on the surface. Brute force may be required in some places. For example, if the wood is completely rotten, it must be removed with a plane or an ax. Items that cannot be cleaned should be thrown away and then removed from the house. It is strongly recommended to remove the soil under floor covering. If fungus was found on the walls or floor, this may indicate that the ground under the house is contaminated with spores. How to remove mold in this case? To clean the area you will need to treat it special solution. You can use dry clay, limestone, cement and crushed stone (it can be replaced with expanded clay).
It is very important to ensure good ventilation in this area.
Wood treatment solutions
How to get rid of fungus in the house using special means? Wood can be cleaned and treated using an antiseptic primer. She is considered the most effective drug among all means. The primer actively destroys spores and microorganisms and prevents the appearance of new affected areas. This drug has an affordable price.
The cleaned area should be provided with regular ventilation for several days.
You can clean mold in your home using bleach, as it helps get rid of organic matter and spores. Bleach can be replaced with vinegar. 
Areas with fungus can be cleaned using baking soda, ammonia, sodium fluoride. First, you should thoroughly rinse the surface, dry it, and then treat it with the selected product.
If you know that dampness in your home periodically appears during a certain season, then you should find out in advance how to get rid of it and its possible consequences.
How to get rid of the floor in a private house
How to get rid of dampness in a private home if mold appears on the floor?
Removing mold from a private home requires more time than this procedure I would borrow it in the apartment. Typically, in such a situation, there is much more area to inspect and look for signs of mold.
If you find signs of mold or mildew on the floor, you can use one of the special preparations or potent active agents.
Not every one of us pays attention to the level of humidity in our home, but it is this indicator, along with air temperature and lighting, that is involved in creating a microclimate and directly affects our well-being. Both low and high humidity are harmful.
Optimal values. If we focus on sanitary standards, then the normal level of relative humidity for a living space varies from 40 to 60%. In winter, when the air is dried out by hot heating radiators, the humidity “drops” to 15-20%, air humidifiers come to the rescue. But in the warm season, indicators often go off scale in the opposite direction, which leads to unpleasant consequences.
Consequences. Negative influence High humidity on the human body is not exaggerated. Firstly, heavy humid air is contraindicated for people with cardiovascular diseases, hypertension and asthmatics. Secondly, in combination with elevated air temperatures (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 adults healthy people breathing is impaired, performance decreases, allergic reactions occur, to say nothing of the “risk zone” - the elderly and young children.
High humidity leads to mold growth In addition, high humidity in an apartment contributes to the appearance of mold and mildew on any surfaces and can ruin furniture, books, bed linen and mattresses, and food (cereals, flour, vegetables). A persistent “swampy” smell appears in the house.
How to measure humidity levels
A hygrometer is useful at home. More like a digital alarm clock, this device monitors rising or falling humidity.
Hygrometer - the simplest device for measuring humidity However, you can find out whether the humidity is high or not by using ordinary water. Fill a transparent glass halfway and place it in the refrigerator for several hours (“at the outlet” the water temperature should be no more than 5°C). Place the vessel in the “test” room, away from household appliances and radiators, observe for 5-10 minutes. Large drops of condensation that appear 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. Inoperative ventilation. Hoods tend to break, and ventilation shafts tend to become clogged. And if in the warm season you can open the window to ventilate the room or kitchen, then in winter this is problematic. Be sure to check the operation of the ventilation in your apartment or house. If necessary, install a hood in the kitchen, a more powerful fan or deflector 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 condensation and “releasing” it all into the room. Constantly damp wallpaper or “squeaking” linoleum is a reason to start repairing.
3. No heating. Rooms that are heated to a minimum dampen most quickly. Installing an additional radiator or purchasing an oil heater solves this problem.
4. Availability of sources of moisture. Perhaps the most common reason for high humidity in an apartment: poor quality installed double glazed windows collecting condensation, errors when connecting a washing machine or dishwasher, leaking pipes or plumbing. “Walk” through all components and connections, if necessary, replace or repair problem areas.
Wrong installed windows- the most common reason If in an apartment, treat the glass with a special composition: 5 parts of transparent dishwashing gel or liquid soap, 3 parts glycerin, 1 part turpentine, and then rub them until shiny with a clean rag.
Prevention of high humidity
Basic but effective preventive actions will not be superfluous even if everything is in order with humidity in the house.
- Be sure to ventilate your apartment (even in winter) at least half an hour a day.
- Heat the rooms evenly, preventing already heated air from entering the “cold” room, creating a sharp temperature difference.
- Do not dry clothes in living areas and bathrooms; it is best to do this on a balcony or loggia.
- Use simple but effective absorbents. Place bags of table salt, rice, and coffee beans in cabinets, on shelves in the toilet, bathroom, and kitchen.
- Run the dehumidifier periodically. This unit passes excessively humid air through filters, which helps maintain a natural and healthy microclimate.
Example of an electric dehumidifier
Excessive dampness often becomes a diagnosis of private houses, city high-rises and dachas. 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 sharply negative effect on the health of the residents. In this case, the root cause - increased humidity - is ignored, so the mold soon returns. Only an analysis of the situation and an integrated approach will help you get rid of dampness.
Causes of high humidity
There are several hundred types of household mold in nature. The main factor in their appearance in residential premises is excessive dampness. The fungus forms in places with poor ventilation on surfaces prone to sudden temperature changes. In other words, if there is a cold wall in your house, 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 your cravings ventilation ducts using a regular match. Its weakening or cessation occurs for the following reasons:
- mistakes made by builders even at the stage of building a house;
- illegal interference in the integrity of the channels of your vertical neighbors;
- failure of parts of the system due to the old age of the house.
Fungal plaque appears due to dampness
It is difficult to eliminate ventilation in a high-rise building. Building management companies, as a rule, do this only if a global restructuring or reconstruction of the building is planned. You'll have to hope for folk remedies eliminating 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 apartment buildings or in private houses, dampness may appear due to flooding of the basement due to 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. Fight against fungal plaque
To get rid of dampness, first of all you need to identify and eliminate all fungal plaque on the walls. Delay can cause the development of diseases. Fungal spores enter the lungs with the air and disrupt function. respiratory system. Dampness and mold can cause acute respiratory infections, bronchitis, asthma and other respiratory diseases, including tuberculosis. In addition, it suppresses the immune system. For residents of the house, especially children and the elderly, this manifests itself in a deterioration in health, allergic reactions and exacerbation of all kinds of ailments.
Attention! The dark coating that appears due to dampness may not be immediately visible. But a strong musty smell will immediately give away the problem.
During the cleaning process, it is important not only to clean, but also to disinfect all surfaces where there is fungus. Use any suitable means:
- chlorine bleach and other chemicals;
- vinegar;
- hydrogen peroxide;
- soda;
- ammonia;
- tea tree oil, etc.
Attention! Wear gloves and a mask when working with any type of cleaning agent against dampness and fungus.
It is important that close contact does not introduce large quantities of spores into your respiratory tract. When using special store-bought products, 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 combat mold and dampness.
If mold has extensively covered the surface of the wallpaper, get ready to rip it off the wall. The mycelium of the fungus is located under the paper layer. There are no means to kill it without damaging the wallpaper itself. In this case, the plaster will probably also have to be removed. First, thoroughly clean the surface of fungus, and then treat it with an antiseptic. For example, an aqueous solution of office glue (1:4) or urea. Before any further work To get rid of dampness, the wall section must dry completely.
Advice. For the disinfectant to work effectively, 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 this position. After 2-3 hours, remove and check the surface:
- dry - source of indoor humidity;
- damp - dampness penetrates from outside.
In the second case it 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. It's better to use them in combination.
- Thermal insulation of the wall. Cover it with breathable insulating material. Today many people 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 up 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. Do some rearranging.
Traditional methods to get rid of dampness due to poor ventilation:
- Place bags of sugar or salt.
- Place small containers of potassium chloride in the corners.
- Heat the bricks and lean them against the wall. Repeat until the surface is free of dampness. Use 1 brick no more than 3-4 times, then it should dry.
- Treat the wall in 2-3 layers with a decoction of laundry soap (100 g/l, bring to a boil and cool). After drying, apply the following solution with a brush: 100 g of alum per 6 liters of water.
Attention! Do not use sprays or other antifungal agents, and to dry the house - air conditioning.
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.
