How dangerous is black mold in the house for the human body and how to get rid of it?

How dangerous is black mold in the house for the human body and how to get rid of it is a complex question that worries many people. After all, some residents have to periodically deal with the appearance of black mold fungi in their own apartment or private house. It is extremely unpleasant to see colonies of fungi on products that have been lying on the shelf for a long time, or on the walls in the bathroom and other rooms.

This problem should be dealt with immediately, because mold provokes various diseases in family members. However, it is not possible to do this quickly in all cases, but you also cannot leave the problem without a solution. In order to find the best way to get rid of the scourge, we will look at the dangerous consequences of fungi, what types most often appear in apartments and how to deal with them yourself.

How dangerous is black mold in the house for the human body and how to get rid of it?

Where does it get into the house from?

Such mold can enter a house or apartment through open windows, balconies, blown in by the wind, or perhaps through ventilation openings. Frozen mold cells seem to be just waiting for an optimal habitat for them to appear in the bathroom or kitchen, or somewhere else - high humidity and a temperature of at least 10-12 degrees Celsius. She really loves musty rooms where there is no frequent airing or good ventilation.

Therefore, it is extremely important to regularly ventilate your home or repair the ventilation shafts. Where condensation accumulates, mold often forms as well.

Therefore, the pipes of all communications in an apartment or house need to be properly insulated. Or insulate the walls themselves outside the house.

How to get rid of black mold

The first step is to thoroughly dry the apartment and ensure good ventilation. Since high humidity, especially above 80%, is the most favorable environment for the development of mold.

To get rid of fungus on the walls, it is not enough just to remove it and make superficial cosmetic repairs. Usually the parasite eats quite deeply into the structure of plaster, wood and other material on which it forms, so after simple cleaning and painting, mold can still appear in the same place over time and continue to grow. To avoid this, very careful repairs must be made.

If the room is in unfavorable conditions and has a predisposition to the formation of fungus, it is worth abandoning the decoration with wallpaper and tiles, in which mold can grow. In this case, it is best to use paint with the addition of special anti-fungal agents.

The most important thing is to treat the affected surface and everything adjacent to it with antifungal agents. In hardware stores you can find a wide variety of different solutions and preparations that will not only quickly get rid of mold, but also prevent its further appearance. For the effect to be reliable and last a long time, the product should be applied in two or three layers.

It is important to remember that any measures to remove mold and treat with antifungal agents are best carried out with gloves and a respirator, as well as in clothes that you don’t mind getting rid of later

These precautions are necessary to prevent the subsequent spread of the fungus.

Among folk remedies for black mold, a 9% vinegar solution is quite popular, which needs to be used to wipe off contaminated surfaces in the apartment. Also, some people use various bleaches against fungus, but they may not always be quite effective. In addition, they are not entirely beneficial for the body and, like mold, can be dangerous for the body, so it is best to use specialized preparations.

Modern anti-fungal remedies cope very well with this problem and allow you to get rid of it for a long time, unlike a solution of vinegar and bleach. However, it is still worth periodically checking areas where mold may appear in order to notice the problem in time and prevent it from spreading.

If the area affected by the fungus is too large, you should not try to get rid of the mold yourself. In this case, it is better to contact specialists. They will thoroughly treat all surfaces and guarantee that mold will not appear in this area again. They will also be able to advise you on the measures that need to be taken to prevent the formation of fungus.

What promotes the growth of fungi?

We only looked at the risk of mold spreading. However, in order to get rid of this problem, it is necessary to become familiar with the reasons why microorganisms multiply. It is necessary to find out which ways the spores get inside in order to carry out control measures in a timely manner.

Heat and moisture are factors that promote the proliferation of microorganisms. Active growth of colonies often occurs at air humidity above 75% and temperatures from 20 to 30 degrees. If the room is not yet properly ventilated, colonies will spread much faster.

It can be much easier to prevent mold from appearing than to deal with the consequences of this scourge.

Moreover, in order to eliminate dangerous causes, no financial investments will be required, because even basic ventilation of the room can save the situation.

There are other factors influencing this process that are usually ignored. So, it is obvious that the problem has increased with the advent of new technologies for construction work.

Plastic windows and doors

Now almost all owners of apartments and private houses are switching to plastic windows, because such structures provide sound insulation compared to their wooden counterparts.

In addition, plastic windows retain heat in the room in the best way and do not require complex maintenance. As a rule, plastic structures are characterized by long-term operation. However, improper installation and continued use of plastic windows leads to the spread of mold.

Often fumes accumulate on window glass if they are installed by an unqualified technician.

The peculiarity is that such structures are closed hermetically, this in turn disrupts the air circulation that exists in the presence of wooden structures. In addition, condensation on the surface accumulates even if the number of glasses is incorrectly selected, poor-quality materials, or violations during the installation process.

This means that the presence of plastic windows or doors increases indoor humidity. However, window manufacturers anticipated this problem and created a special ventilation valve. Therefore, regardless of the time of year, it is recommended to ventilate the room, otherwise it will not be possible to avoid the accumulation of fungal colonies.

In a special article we will tell you why plastic windows fog up inside and can this be avoided?

Consequences of excessive dampness - mold spots on slopes and walls

Plasterboard panels

This building material is preferred by many craftsmen, because its use allows you to finish even an uneven wall. In addition, such panels are used to make shaped partitions and various structures with horizontal and vertical elements.

Therefore, in order not to turn the room into a real “breeding ground” for mold, it is necessary to adhere to the installation rules. So, when finishing the panels, you should wait time for the plaster to dry.

Expert opinion: Masalsky A.V.

Editor of the “construction” category on the Stroyday.ru portal. Specialist in engineering systems and drainage.

If you are going to use plasterboard to finish a room with a high level of humidity, then you need to choose panels that are suitable for such conditions. In addition, during the finishing process, primer and plaster with the addition of antiseptics should be used.

When making plasterboard structures, it should be taken into account that this material absorbs moisture, which lingers inside for a long time

Poor ventilation

It is quite rare that windows are installed indoors in a plumbing unit, but in addition, there is often no normal ventilation there. Because of this, there is an excessive level of moisture inside, because a bath, shower, washing machine, clothes dryer and towels are installed there - natural ventilation is clearly not enough here.

All that remains is to install a high-quality exhaust system. This will solve the existing mold problem and also prevent it from recurring.

Constant contact of floors with water causes rapid growth of fungal colonies

Floor humidity

There are often situations when, when creating a project for an apartment or private building, the point of formation of evaporation on the floors is not taken into account. This leads to the fact that during heavy rains or cold weather the walls freeze and become damp. Over time, mold colonies will spread on surfaces.

The danger is that at first the fungi appear from the outside, but after a while they rush into the depths of the ceiling and grow inside. The process occurs much faster when there is damage and microcracks on the walls.

Often the source of fungi is the basement, where there is high humidity at any time of the year. From there, the spores spread to other rooms through ventilation.

If we are talking about your own home, then you need to take care of creating reliable ventilation yourself. When the source of mold is the basement of a multi-story building, you should contact the housing office employees.

The presence of multiple colonies of black mold contributes to the weakening of load-bearing walls, therefore there is a risk of destruction

Prevention of black mold

If the bathroom, toilet or other rooms are infected with black mold, then measures should be taken immediately

But it is equally important to eliminate the causes that lead to the harmful effects of pathogenic microorganisms. To prevent black mold spores from forming for the first time or from forming after they have been eliminated, you need to remember the following nuances:

• Ventilate the room regularly. Forced ventilation must be provided if required. You also need to regularly clean the ventilation from dirt and check how the hood works. Ventilation of the room as a whole is mandatory in the winter season. In summer, you need to ensure that sunlight enters the room. You also need to make sure that there is no garbage stored in the house, no rotten vegetables and fruits, and the like.
• Control the humidity in the apartment as a whole. If there are suspicions that the humidity level is elevated and this can lead to negative consequences, then it makes sense to buy a device that will measure humidity. The optimal figure is about 70 percent. If the humidity in the room is higher, then you need to remove its cause.
• Check the operation of the plumbing. Black mold often forms on toilets, faucets, or taps. Any existing leaks must be repaired. If the house has old pipes, then it makes sense to replace them with new ones.
• Rearrange the apartment. Furniture should not fit tightly against the walls. In this case, there will be no air space and then there is a high risk of the formation of pathogenic microflora.

Black mold is a dangerous type of microorganism that harms the human body.

Therefore, it is very important not only to take control measures, but also to ensure high-quality prevention

Types of mold

Mold that can be found in an apartment can have several types:

• white mold (mukor)
  usually “settles” in flower pots, covering the walls of the pot, the soil and the plants themselves with a white coating. The appearance of such mold indicates excessive moisture in the soil. You can also find white mold on baked goods and cheeses;
• green mold
  “loves” to appear on food products as a result of processes: fermentation, mustiness, rotting. Eating contaminated food can result in poisoning. Green mold also sometimes affects some types of building materials, such as brick;
• pink mold
  affects food that has not been stored properly. Having appeared on food, this mold easily spreads to hard surfaces: floors, walls, ceilings. This type of fungus does not penetrate deep into the structure of materials, thereby not destroying them, and if it enters the body with food, it can cause poisoning;
• black mold
  is the main enemy of home interiors and comfort. This is the most common type of fungus and can affect all surfaces: wallpaper, paint, plaster, wood, concrete, etc. Black mold spores are dangerous to health even in the short term.
• blue mold
  usually appears on wooden surfaces in the house: parquet floors, wooden frames, furniture. The wood begins to acquire an unpleasant dull blue tint, and the paintwork is destroyed;
• Rotting mold
  also affects wood materials. This type of lesion is characterized by gray-brown spots. Penetrating into the tree, the fungus corrodes it: the tree becomes thinner and cracks appear.
• gray mold
  is a serious “disease” of food and plants. It spreads easily, is toxic and is contagious to many fruits, vegetables and plant seeds.

The types of mold listed above have one thing in common: they are attracted to high humidity.

Types of black mold

Black mold, in turn, is also divided into subspecies. Let's look at the most common and dangerous ones that we may encounter in our homes.

Black Aspergillus (Aspergillus niger)

is a type of higher mold fungi from the genus Aspergillus (Aspergillus), which causes diseases in humans and animals, primarily affecting the lungs. The spores of these fungi scatter throughout the apartment, settling on furniture, clothing, food, animal hair, human skin and easily enter the body.

Aspergillus fumigates

comes out in places of mechanical damage to fruits and vegetables. If baked goods are baked from seeds susceptible to this dangerous fungus, black fluffy spots or mold will soon form on the baked goods. Fuming Aspergillus spores are highly allergenic and can destroy red blood cells, suppressing the production of immunity.

Alternaria alternata

lives on dead parts of plants, on autumn leaves, on overripe fruits and tubers. Often found on textiles, products, including meat. Externally, the colonies of this fungus look like spots from black to green-olive. Spread of spores occurs even at low humidity levels on sunny, windy days.

How to get rid of it: effective methods

Mold has appeared on the wall in the apartment: what to do? Before you start using various drugs and remedies, eliminate favorable conditions for the active functioning of the fungus. Having destroyed the uninvited guests for a short time without performing the necessary manipulations, the mold will again settle in the house.

Destruction of favorable conditions

Recommendations:

improve heating. Make sure that radiators and other heating devices heat the entire room, and not a separate object (move them away from the sofa, wall, place them so that warm air blows into the space)

It is important to ensure that the room is heated evenly; do not keep the bath closed; if this room is not heated, the likelihood of mold growing increases;

provide high-quality thermal insulation. Main problem areas: joints between walls and floors, ceilings, doorways, window perimeter

Cracks are formed as a result of non-compliance with construction technology and cosmetic work;

improve ventilation in the house. Walk around the apartment with a candle, if the fire does not move in the direction of the ventilation holes, then clean them and correct the problem immediately. Also check the neighboring apartments; it is likely that the problem lies in their ventilation;

Eliminate sources of water leakage. Seal the pipes and change the finishing material around this area. If this is not possible, then dry the surfaces with an industrial hair dryer and treat with an antiseptic;

fight capillary moisture. It oozes from neighbors or through finishing material from the street. Waterproofing walls and ceilings will help fix the problem; pay special attention to water pipes;

get rid of hydrophilic materials in rooms with high humidity. Such items can be products made from fabrics or wood; remove them from the bathroom, if possible from the kitchen, replace them with hydrophilic products made from modern materials.

Having followed all the necessary recommendations, you will immediately feel an improvement in the microclimate in your home, and your health will also return to normal.

Fighting fungal colonies

Now start fighting the fungus directly in the apartment mechanically using a variety of means

Recipes:

antiseptic primer. It is easy to find in any hardware store, use Stop-mold, Alpa, Dali and others. Their use will help not only destroy existing fungal colonies, but also prevent the reappearance of uninvited “guests”

It is important to thoroughly clean the wall before processing; if necessary, remove all finishing material down to the brick;

There are bleaches in every home, they do an excellent job not only with stains, they quickly kill mold, and are an excellent alternative to professional products. Do not use the preparations on all surfaces; some of them will be impossible to restore later.

Bleach is allowed to be used on bathroom tiles, the bathtub itself, and glass surfaces. Disadvantage of this method: bleaches are not effective on drywall and wood. Wear gloves during the procedure, dilute bleach with water in a ratio of 1:10;

vinegar, hydrogen peroxide, ammonia. These remedies for mold on the walls in the apartment have destructive power; they are used together with water in equal proportions. Treat the desired surface with the resulting raster, do not wash off. To obtain the desired result, repeat the manipulations several times.

tea tree oil. It is the safest remedy for humans, but destructive for mold. Take a teaspoon of ether per glass of water, place the solution in a spray bottle, and treat the desired surface. Pleasant aroma, absence of fungus - guaranteed.

Folk methods of struggle

The most commonly used means for eliminating mold are:

• Table vinegar (undiluted). The substance should be applied to the affected surface from a spray bottle or washed with a cloth soaked in vinegar. If necessary, repeat the treatment 2-3 times.
• Baking soda. Can be used as a solution of 1 liter of water and 2 tbsp. l. soda or rub the surface with soda paste. A good effect is achieved by using vinegar and soda at the same time: first you need to pour dry soda, and spray vinegar on top - during the reaction of the two components, fungal spores will be destroyed. These safe products will help get rid of mold in the bathroom, in the living room, and even in the refrigerator if the unit has suddenly become a breeding ground for fungus.
• Hydrogen peroxide (3%). The pharmaceutical preparation should be applied to the surface affected by mold and left to act for 10-15 minutes. Peroxide will perfectly eliminate fungal colonies in tile joints, under old wallpaper, on the lid of an aquarium and in other places.
• Ammonia or medical alcohol. It is recommended to spray the walls or ceiling with a spray bottle or with a sponge soaked in the selected preparation. Leave for about an hour so that the active substance has time to destroy visible traces and invisible mold spores.
• An aqueous solution of copper sulfate. For the desired effect, you need to dilute 100 g of the drug in 10 liters of water. The resulting solution can be used to treat any surface, but it should be taken into account that they will turn blue.
• Bleach and other household chemicals with chlorine (Belizna, Domestos, Santry). Can be used concentrated or diluted with water. Products of this type are suitable for treating walls before finishing work, as well as for soaking clothes and textiles with signs of mold.
• Tea tree or grapefruit seed essential oil. Suitable for surfaces with a slight degree of fungal damage. 20 drops of an aromatic substance should be mixed in 0.5 liters of water, poured into a spray bottle and generously moisten the affected surface with this solution. After drying, the solution does not need to be washed off - it will create a protective barrier that prevents the development of mold in the future.

After cleaning with improvised means, treated walls or ceilings must be rinsed with clean water to remove any remaining fungus and active ingredients.

When working to eliminate black mold, you must wear safety glasses, gloves, and a respirator. This measure will minimize the harm from inhaling spores. The remaining rooms must be insulated by sealing the entrance to them with any sealed material.

This is what protective equipment should look like during antifungal treatment of a room

General information

Mold appears on various surfaces and can grow very actively, destroying the room and rendering it unusable. Microorganisms pose a particular danger to the human body. Regardless of what you plan to do to remove mold, it is important to know the reasons for its appearance so that it does not reappear in the room.

Harm to humans

Black mold is a fungus that is extremely dangerous for adults and children. Toxic substances released by colonies of these microorganisms can cause:

• dermatitis, eczema, psoriasis;
• asthma, pneumonia, other diseases of the respiratory system;
• joint diseases;
• conjunctivitis;
• disorders of the kidneys and liver;
• dental problems (stomatitis, thrush);
• candidiasis on the genitals.

Scientists suggest that the more dangerous mold there is, the higher the likelihood of cancer. Spores penetrate the body, settle on internal organs and mucous membranes, and activate the process of decomposition of cells and tissues.

When the body is infected with mold, diagnosis is very difficult, since this type of mold is not always distinguishable. As a result, therapy is prescribed too late, and at best the disease develops into a chronic form, and at worst, irreversible consequences arise.

Viable mushrooms are very difficult to breed; they can survive in the cold and at high air temperatures. The death of microorganisms is observed only during boiling.

Black mold in the house is dangerous for humans and the longer its presence in the home, the higher the likelihood of the following symptoms occurring:

• active hair loss;
• memory impairment;
• numbness of the limbs;
• pain and other discomfort in the abdominal cavity;
• eye sensitivity to light;
• causeless increase in body weight;
• muscle cramps.

Reasons for appearance

The appearance and spread of black plaque is promoted by heat and moisture. In this case, the most optimal conditions are humidity up to 68% and air temperature up to 25 °C). If the room is rarely ventilated, fungus will definitely appear.

Other factors:

• Doors and windows with plastic profiles. If used incorrectly, they are a provoking factor. Plastic profiles prevent constant air movement due to their tightness. If the installation was carried out incorrectly, and the products themselves are of poor quality, condensation occurs. This creates suitable conditions for active growth and development of the fungus. The solution to the problem is a supply valve on the windows and regular ventilation of the premises.
• Drywall. The material is able to absorb moisture and retain it for a long time. In order to prevent black mold from developing, you need to follow all the rules for installing structures and leave enough time for them to dry completely. There are special types of drywall designed for high humidity conditions if installation is carried out in such a room. Antifungal compounds must be added to the solutions used.

• Insufficient ventilation. Most often, this problem occurs in the bathroom and toilet. The absence of windows, regular water procedures, and drying clothes contribute to a significant increase in air humidity, which an ordinary hood cannot cope with. Forced ventilation comes to the rescue.
• Damp walls and ceiling, damp environment in the basement. Sometimes errors at the design and construction stage lead to the fact that when precipitation falls, the corners of buildings get wet and then freeze in the winter season. The same thing happens if drainpipes are clogged or missing. In a damp basement, mold fungi can actively multiply and then penetrate through the ventilation system into living rooms and other rooms.
• Food. If store-bought bread was baked from moldy grain, it will very quickly become covered with a fungal coating. This product is dangerous to life. The piece should be packed in a plastic bag and thrown into a trash bin outside the home.

First signs

If black mold fungi have settled in the house, you can understand this by the following signs:

• dark spots, stains, persistent deposits on walls and other surfaces;
• darkening of the seams between tile panels in the bathroom, bathroom or kitchen;
• specific smell from air conditioning or heating devices;
• wallpaper coming away from the walls;
• persistent colds in residents, the appearance of symptoms of bronchial asthma, allergies, itching;
• musty indoor air;
• an unreasonable feeling of fatigue and loss of strength;
• cases of flooding in the bathroom or toilet.

Types of black mold

A black mold coating, which is visible to the naked eye, is an external manifestation of fungal colonies. Such microorganisms can be of different types, but the most common types found in residential areas are:

• Aspergillus black. It actively reproduces and exists in a humid environment, which is present in the bathroom, toilet, swimming pool, kitchen. This type of mold can often be seen in washing machines, air conditioners, and home humidifiers. Even with the slightest fluctuation in the wind, spores are spread throughout the room, penetrate the respiratory tract of humans and animals, and settle on clothing and food. Mold causes serious pathological processes in the human body, including death.
• Aspergillus fume. This type of fungus is resistant to high temperatures (up to 55°C). The spores easily enter the human body due to their very small size. People with weakened immune systems are most susceptible to infection. Most often, such mold is found on vegetables and fruits with mechanical damage. Toxins released by fungi cause allergies and destroy red blood cells (erythrocytes) in biological material, preventing the strengthening of the immune system.
• Alternaria alternata. Most often, such a fungus can be found on dying autumn leaves, spoiled vegetables and fruits. Microorganisms easily take root on food, clothing and other textiles. The fungus loves moisture, but the spores spread in dry, windy weather under the sun's rays. Wooden houses are susceptible to the penetration of such mold to a greater extent than concrete buildings.

Mold Dangers to Pets and Houseplants

It turns out that mold is harmful not only to people, but also to other living inhabitants of a private house or apartment. We are talking about indoor plants and pets.

Thus, an insidious fungus more often than usual affects flowers that do not require intensive watering, and therefore are not able to absorb a lot of moisture at once (for example, cacti, aloe, violets, “money tree”, etc.) At the same time, mold can attack both soil and and the plant itself (in this case, the leaves begin to rot, turn black, and curl).

Mold can affect both the indoor plant itself and the soil in which it grows.

Of course, mold affects the plant negatively:

1. Deteriorates soil quality. It disrupts water and mineral metabolism, acid-base balance.
2. Death of the plant. The top layer of soil can turn into a crust that retains moisture and does not allow air to pass through. The roots begin to rot, then the branches and leaves die.
3. Mold can “move” onto the windowsill, window frames, walls, and ceiling.

As for pets, if they inhale spores or tactile contact with mold, they may experience breathing problems (including pulmonary edema) and disruptions in the functioning of the nervous system. In case of severe poisoning, death cannot be ruled out.

How to determine the presence of mold in an apartment

The presence of fungus cannot always be determined visually. Mold on the walls of an apartment can be hidden under wallpaper and in other hard-to-reach places. Let's figure out what signs can tell us that mold “lives” in the apartment.

1. Stains on the walls.
   Most often they can be found in the area of ​​​​joints, in places where the wall has frozen and where leaks and flooding have been noticed more than once.
2. Unusual smell and taste.
   Almost all types of mold emit a pungent “aroma.” It vaguely resembles the smell of dampness: a basement, a storage room in an old private house, the smell of stagnant water, mud. Pay attention to how your home smells, whether there are any unnecessary odors. If you notice a musty odor or unpleasant taste when brushing your teeth, your toothbrush may be carrying fungus. In this case, you need to inspect the bathroom for mold and replace the cleaning accessories. In the same way (by smell) you need to check washcloths, towels, rugs and curtains.
3. Condensate.
   High humidity levels and ventilation problems can cause windows to fog up (condensation). The same goes for mirrors and household appliances in the bathroom.
4. Rust on the pipes in the apartment.
   If possible, pay attention to the pipes laid in the bathroom. The presence of rust indicates high humidity, which means that somewhere nearby there may be a source of fungal mold.
5. Itching of the mucous membranes and sore throat
   can be a manifestation of an allergy to dust or toxic mold. If the symptoms do not subside after airing and wet cleaning, then it is worth checking the rooms for the presence of mold.
6. Postnasal drip
   is one of the clear signs of a mold allergy, characterized by the production of excessive mucus in the nasopharynx. In addition, sneezing, dry cough, rhinitis and other symptoms may appear.
7. Damp basement.
   If you live in a private house, pay attention to the condition of the basement and cellar. During the period of snow melting, water can accumulate in the basement area until it floods. The basement in a private home is a favorite place for mold due to poor ventilation and condensation.
8. Faulty ventilation.
   In an apartment where it is constantly stuffy and condensation accumulates, mold most often forms. Due to difficult air exchange in the room, the microclimate is depressed: the concentration of carbon dioxide, humidity and air temperature increase. Plastic windows are sealed and do not allow air to pass through. Under such conditions, dampness in the apartment becomes constant, which leads to the formation of mold.
9. Trouble breathing and a feeling of chest tightness
   are common signs that mold is rampant in your home. Therefore, if there are no viral diseases, but the symptoms persist, this is a reason to think about cleaning the apartment from mold.
10. Air analysis.
    You can check for mold in the air using a smart mold probe. Fungus control specialists have such devices. Be sure to ask for a license to conduct the survey.

Danger to humans

Why is mold on walls dangerous for humans? If its pores enter the human body, it can cause a number of serious diseases, among which are the following:

• skin diseases that are difficult to treat - acute dermatoses or mycoses;
• damage to the respiratory tract, which can result in chronic runny nose and cough;
• diseases of the musculoskeletal system;
• development of articular-rheumatic diseases;
• Lethargy, exhaustion, frequent migraines are the most characteristic first signs for a person “infected” with fungal spores in an apartment.

The mold itself, which occurs due to dampness, is not dangerous.

The spores that form in it are directly harmful. They can enter the human body with the air flow through the respiratory tract. Their impact is quite strong; they are powerful allergens that cause serious ailments in humans from conjunctivitis to respiratory allergosis.

Mold in the house can also lead to the development of bronchial asthma, and all this is due to the neglect by apartment owners of the basic rules regarding maintaining the proper level of humidity in the room.

Methods of combating and how to treat walls against black mold

Having found out all the reasons for the appearance of mold, we began to try to eliminate them on our own. If you encounter such a problem, I recommend you the following:

Clean the walls from wallpaper, whitewash, plaster, in a word, tear off everything you can.

Buy an acetone solution

Ventilate the room well

When you return home, try to thoroughly dry the walls and all surfaces that you treated.

Install ventilation systems

Buy anti-mold impregnation and treat the room with it.

I would also like to talk about furniture

7. Separately, I would like to talk about furniture. It is also exposed to mold. We treated the furniture with an acetone solution, and this was our main mistake. Perhaps the fungus began to spread again from the cabinets and sofas. So don’t spare money and mercilessly get rid of old things, no matter how dear they are to you. The whole tragedy of our family is that we took all this furniture with us to our new house. All requirements for preventing the appearance of mold were met there (high-quality materials, ventilation and air conditioning), but after 1.5 years of residence, the fungus again attacked the walls. We had to get rid of it again, and we still threw out the old sofas and armchairs. Don't repeat our mistakes!

Fungicidal preparations

In advanced cases, when mold has affected a large surface or its spores have penetrated deep into materials, you will have to seek help from special fungicidal preparations produced by the chemical industry. These are various antifungal agents designed to destroy the fungus or prevent its occurrence. Their range is wide, and you can purchase products of this kind at any hardware or hardware store.

Before purchasing fungicidal compounds, you must carefully read the instructions so as not to make a mistake in your choice, since they differ in purpose, method of application and type of surfaces to be treated. For example, the QUELYD Anti-Mold product is available in two versions: for removing mold in living rooms and bedrooms or in bathrooms and toilets. Both drugs are suitable for sanitation and repair.

Biodom, SANATEX, PROSEPT FUNGI STOP will help as an emergency aid. They successfully fight various types of mold, moss and lichen and can be used on almost all building materials: concrete, brick, wood, slate, plaster, granite, tiles and even wallpaper.

How to get rid of black mold?

Thorough mold removal can relieve symptoms. This may require thoroughly removing mold from all surfaces in a person's home or workplace and taking steps to prevent it. There are many cleaning products that can kill mold and prevent it from coming back. You can also make a cleaning solution at home by adding 1 cup of household bleach to 3.5 liters of water.

When working with bleach or harsh cleaning products, it is essential to wear protective gloves and goggles. The entire room must be thoroughly cleaned and all signs of mold have been removed.

You should also dry the surfaces to avoid future contamination. It is recommended to clean all filters and vents whenever possible to prevent mold growth in air conditioning systems and humidifiers.

Porous items with mold, such as mattresses, carpets or drywall, can be difficult to clean. They need to be replaced or a professional cleaner hired

During cleaning, it is important to ventilate the room as much as possible by opening doors and windows or turning on fans.

Required Security Measures

Considering that spores, particles of mold itself and the toxins it releases can spread with air currents, gathering to fight fungal colonies, it is necessary to protect your respiratory tract and skin from unwanted contacts.

Safety precautions:

1. Do not neglect personal protective equipment such as a respirator, waterproof gloves and safety glasses.
2. To prevent spores that have been removed from one surface from taking root on another, the surfaces of the furniture and floor must be covered with oilcloth, which you don’t mind throwing away later, or with plastic film.
3. Anything that can be taken out of the room during cleaning is best removed. In the bathroom this could include, for example, washcloths, brushes, towels and curtains.
4. If the situation is serious and mold has managed to take over large areas of the room, all objects that can get fungal spores should be wrapped in film. Choose a thicker film to ensure reliable protection. It is not advisable to save on your health: then you will spend more on medicines.
5. Never turn on the fan while cleaning. Mold spores can easily spread throughout the room, and then there is simply no escape from them: they can appear unexpectedly and in the most inappropriate places.
6. Do not use a household vacuum cleaner to remove fungal colonies. The spores or toxins themselves may end up on the inside of this household appliance. The spores in the vacuum cleaner do not die, but simply wait in the wings and suitable conditions for the revival of the colonies.
7. But the dehumidifier, if there is such a device in the house, should be turned on. Dried air will deprive microorganisms of the chance to continue existing.
8. After cleaning the contaminated area, you must throw away all rags, brushes, gloves and films along with the respirator.

Fighting mold is an inevitable event in case mold has already started . But it is much better to prevent its occurrence by not creating conditions for the development of fungal colonies.

What is black mold?

Some types of mold can produce mycotoxins
. Black mold is a type of fungus that is dark green or black in color and often has a distinct musty or damp, musty odor.

Black mold can be one of several types of fungi, including Stachybotrys chartum.

It likes to appear on surfaces that contain a lot of cellulose, such as fiberboard, wood, drywall or paper. Mold prefers moist, warm environments, growing in the right conditions.

Black mold often thrives in damp areas, including bathrooms, laundry rooms and shower stalls. It can also appear after a pipe burst or flooding, especially in areas of the building that a person cannot easily see - for example, between layers of walls, under floors or carpets.

These fungi are not dangerous in themselves, but they can release harmful toxins into the environment. Inhaling these toxins can affect your health and cause certain symptoms. People with lung disease or weakened immune systems tend to have a higher risk of negative health effects from mold.

Groups of microorganisms in mold

Mold can be classified in different ways. The easiest option is to combine varieties by color. Fungus that grows on walls, soil or food can be black, white, pink, blue, green, or yellow.

If we approach the issue from a scientific point of view, mold can be divided into 2 main categories:

• zygomycetes;
• ascomycetes.

Mold

Zygomycetes are unicellular organisms with highly overgrown mycelium. On the surface of the cell there is a large number of so-called “chupa chups” - closed balls on legs, similar to the famous candies. There are spores inside these balls.

Ascomycetes are fungi with multicellular mycelium. Organisms are spherical in shape, on the surface of which there are chains of spores.

Fungus damage

There are about one hundred thousand types of mold in total. Only a few are considered beneficial to the environment, while the rest cause great damage to humanity. Let's find out why the mushroom is dangerous. It chooses warm places with high levels of humidity as its habitat, which is why mold often appears in houses and apartments. It mainly occurs in corner, unventilated or unheated rooms.

The harm of mold to a person is difficult to overestimate, even if he does not have direct contact with it. The fungus releases toxic substances directly into the air. So they settle on the skin, causing rashes and itching, and also enter the human body through the respiratory tract, affecting vital organs. Dampness has a negative impact on health, and when interacting with fungal bacteria, it can cause the appearance of neoplasms, including malignant ones.

Mold in the home poses a particular danger to children; their bodies are in the developmental stage and are not resistant to the effects of toxins. Exposure to fungus in children can cause pathological processes that will accompany them into adulthood.

If a child is in constant contact with mold, he can become ill for life

Where does mold live in an apartment?

We wrote earlier that mold prefers to grow in places with high humidity. The first step is to carefully examine:

• places under sinks (in the bathroom and kitchen);
• basements;
• bathroom (shower curtain, protective rubber band of the washing machine and the outer part of the drum);
• places where wallpaper comes off or “bubbles”;
• window sills and window structures;
• ventilation holes;
• under baseboards;
• under flower pots;
• wherever a leak occurs.

Dangerous black mold lives mainly in kitchens, bathrooms (tile joints in rooms with high humidity levels), toilets, swimming pools, humidifiers, air conditioners and washing machines. Colonies of black fungi can form on damp walls, ceilings, etc.

How to get rid of black mold on the walls in an apartment

To effectively combat black mold, you should follow these steps:

• First you need to remove the wallpaper if the area damaged by mold is located under or on it, but it will not be possible to remove the fungus without damaging the surface.
• It is necessary to remove not only the layer of putty, but also the plaster, especially that part of it that has become soft from the action of the fungus.
• After this, you need to clean the area that is affected by mold.
• You can remove traces of mold from the surface of walls or other elements of your home using the following remedies for black mold.

Vinegar

• Vinegar must be poured into a spray bottle and then applied to the affected surface;
• leave the composition for 40–60 minutes;
• refresh the surface with clean water;
• Allow the substance to dry completely.

Ammonia

• mix ammonia with water in equal proportions;
• Using a sprayer, apply to a wall that is affected by mold;
• After a few hours, wash off traces of ammonia from the surface.

Hydrogen peroxide

Peroxide can be purchased at a pharmacy. It fights mold well and disinfects surfaces.

Don't forget that every space in the house that has been treated with mold-fighting substances should be coated with antifungal agents, which can be purchased at a hardware store. This approach will protect yourself from the recurrence of the fungus.

It is best to remove the entire layer of plaster from the wall that is damaged by fungus. If fungal spores remain in the microcracks of the wall, sooner or later the mold will grow again.

Why is fungus dangerous?

The term “black mold” is a general term for several types of fungus. A microorganism, appearing in a comfortable living environment in the form of small pinpoint inclusions, grows quite quickly and, capturing new spaces, turns into spots of different sizes.

Fungal colonies poison the air with toxic secretions and infect with spores, thanks to which they multiply. Toxins and spores, entering the body with air, cause harm to it, from general malaise to severe diseases of organs and systems.

A person in good health may not feel the effects of mold for a certain period of time, but a tenant with a weakened immune system will immediately be attacked and feel its effects on himself. Symptoms will appear in the form of breathing problems, swelling of the mucous membranes, skin irritations, coughing attacks and runny nose. This will serve as a signal to take urgent measures to eliminate mold.

The effect of black mold on the human body

In open space, in nature, fungal spores are not capable of causing significant harm to human health. The situation is different if mold appears in the house. Spores, countless numbers of which are released into the air, enter the respiratory system, causing a toxic effect on the body as a whole. Black mold is especially dangerous for a person in the bathroom, since the steam opens and cleans the pores, which makes it easier for the spores to enter the body.

Against the background of reduced immunity, especially in children, frequent colds and pneumonia are observed. Stomatitis, conjunctivitis, thrush, and nosebleeds are not uncommon. If a person has an allergy, its symptoms will be felt constantly:

• cough;
• runny nose;
• bronchial asthma;
• hay fever;
• itching, rashes on the skin and mucous membranes;
• eczema.

The most dangerous carcinogenic effect leading to cancer:

• liver cancer;
• lungs;
• serious damage to the musculoskeletal system and skeletal system.

In view of such dangerous consequences of the appearance of black mold both on walls and on other surfaces, you should get rid of it promptly and permanently.

Knowing the causes of black mold and how to eliminate it, you can easily cleanse your home of this “uninvited guest.” In addition, do not neglect preventive measures - an important tool in the fight against black and other types of mold.

Why is mold in an apartment dangerous for humans?

Mold spores spread quickly: up to a million spores are formed daily in an affected area of ​​one square meter.

Within three years, the fungus can destroy a concrete partition.

Due to the toxic fumes produced by many types of fungus and their spores, health problems begin. Spores settle on surfaces, on the skin and food, and enter the body through the nose, skin and mouth (with food and by inhalation).

The most common reaction to mold is an allergy. The severity of the effects depends on the time of exposure and individual susceptibility. People with weak immune systems, pregnant women, children and the elderly are most susceptible to allergies to mold in the apartment.

The fungus is equally dangerous to humans through direct and airborne contact. With short-term exposure, the following symptoms appear:

• skin itching and redness;
• tearfulness, dry eyes;
• nosebleeds;
• nervousness;
• swelling of the mucous membrane;
• dry cough;
• headache;
• dizziness;
• disruptions in the gastrointestinal tract;
• insomnia.

Prolonged exposure to mold on the body is fraught with:

• lung diseases (asthma, pneumonia, emphysema);
• liver and kidney damage;
• decreased immunity;
• poisoning;
• exacerbation of symptoms of existing chronic diseases;
• development of cancer.

Careful Mold Removal Provides Long-Term Symptom Relief
For long-term relief of allergy symptoms or black mold poisoning, it is important to avoid or reduce exposure to mold. This may require thoroughly removing mold from all surfaces in a person's home or workplace and taking steps to prevent its return.

There are many commercial cleaning products that can kill mold and prevent it from coming back. Alternatively, people can make a cleaning solution at home by adding 1 cup of household bleach to 4 liters of water

When working with bleach or harsh cleaning agents, it is essential to use protective gloves and goggles

People will need to completely clean the entire room or affected area and make sure they have eliminated all signs of mold. They should also dry surfaces to prevent future regrowth.

It is recommended that all filters, vents and ducts be cleaned whenever possible to prevent mold growth in air conditioning systems and humidifiers.

Porous items with mold contamination, such as mattresses, carpets or drywall, can be difficult to clean. You may need to replace them where possible or hire a professional cleaner.

When cleaning up mold, it is important to ventilate the area as much as possible by opening doors and windows or turning on fans.

Mold Prevention

People can prevent or minimize the possibility of future mold growth by following these guidelines:

• Regularly clean any areas where mold is likely to grow (bathrooms, showers and wet rooms).
• Use a dehumidifier to reduce the amount of moisture in the air, especially in areas where humidity is a problem. Mold prefers to grow in damp and wet places.
• Keep all walls and surfaces dry.
• In cold or damp weather, rooms should be warm and well ventilated.
• Install and use exhaust fans in wet areas such as bathrooms and kitchens, and do not place carpets or rugs in them.
• Check pipes, gutters and air conditioners regularly to avoid possible leaks and water seepage.

Mold in the apartment: reasons for its appearance

Molds are microscopic spore-forming organisms that contain enzymes (responsible for breaking down organic materials) and spores (responsible for the spread of mold). Mold belongs to the kingdom of fungi, which also includes yeast. In terms of flora and fauna, molds are not parasitic organisms. They serve to decompose organic matter, thereby nourishing the soil. In medicine, mold is used to produce some medicines; in cooking - for making cheese.

Mold becomes problematic when it appears in an apartment and lives its life among human comfort, affecting the appearance, smell and integrity of building materials.

Mold in an apartment is familiar even to those who live in new buildings, so the fungus is not an age-related defect. Black plaque on walls and other surfaces in the house not only spoils the aesthetic appearance of the interior, but also poses a danger to human health.

Many people believe that it is enough to remove the visible part of the mold on surfaces to get rid of it. However, in this situation, mold stains usually return within a very short time and continue to spread.

This phenomenon, unpleasant for the eyes, can also be accompanied by an unusual odor, irritate the mucous membranes and cause an allergic reaction.

The main reason for the appearance of mold in an apartment is high humidity (dampness), which can arise due to:

• violations in the ventilation system;
• freezing of walls in cold months (problems with tightness in joints);
• ground dampness (most often in private houses);
• violations in the heating system;
• leaks: in pipes, on the roof, frequent flooding by neighbors;
• low-quality or hygroscopic finishing materials.

A comfortable breeding ground for the development of mold fungi occurs with prolonged exposure to high humidity (more than 60%) coupled with temperature (from +20 °C).

Removing the fungus

How to get rid of black mold with 100% results? A set of measures and desire are required. First, take care of protecting your respiratory system and skin. Then, following the recommendations, do the following:

1. Inspect the premises for any damage. Correct all identified deficiencies.
2. Get rid of all fungus-affected surfaces completely. Removing part of the wallpaper, tiles and other finishing materials is not permissible.
3. Treat the freed walls with antiseptic preparations with antifungal effects. These could be store-bought chemicals or home remedies.
4. Select new finishing materials based on moisture resistance. Use waterproofing products.
5. Equip the premises with additional ventilation devices.
6. Keep the air in your home clean and fresh.
7. Innovate in prevention.
