If unsightly black spots appear on the wallpaper, the wallpaper begins to peel off and it begins to smell like a cellar, it means that mold has settled in your apartment. You won’t be able to just wash it off, and it’s useless.

To stop its spread, you need to start fighting immediately, because it is very quickly conquering new territories.

What needs to be done to prevent mold from appearing?

Bleach: Mix 1 cup of bleach with enough water to make 1 gallon. Borax: Mix 1 cup of borax with enough water to make 1 gallon. Apply the solution to the surface and scrub with a brush; do not wash off. Wipe the surface dry. Vinegar: Use vinegar at full strength in a spray bottle. Spray the affected area and wipe it off. Ammonia: This is suitable for killing mold on smooth, non-porous surfaces. Spray the area with a solution of equal parts ammonia and water, leave for 10 minutes and rinse with water. Hydrogen Peroxide: Spray full strength hydrogen peroxide on the mold surface and let it sit for 10 minutes to loosen the mold. Wipe the surface and do not rinse. Baking Soda: Mix ½ teaspoon baking soda in 1 gallon water and wash moldy surface, then rinse with water. This is especially useful for killing mold on upholstery. Tea Tree Oil: Use 1 teaspoon of tea tree oil per cup of water and spray onto surface. Leave it on for a few minutes and then wipe it off.

  • Place the solution in a spray bottle or apply it with a sponge or cloth.
  • No need to rinse.
The agency also warns against using bleach or biocides because they can cause serious reactions in some people.

You need to understand what reasons are needed for its appearance and spread, what is best to use to remove it, etc.

Causes of mold on wallpaper

The most common reasons:

  1. Moisture is when water vapor condenses on various surfaces in the home, creating favorable environment for rapid mold formation.
  2. The result is a greenhouse effect - a combination of high humidity and heat. It develops already at 95% humidity, and for comfortable living the optimal air humidity should be from 60-80%. Wear or poor sealing of waterproofing joints. Perhaps, if technologies are violated during construction, the use of low-quality building materials
  3. etc. But balconies and loggias also suffer from this, especially at the junction of the slabs Mass installation plastic windows leads to a lack of natural ventilation in the house.
  4. And if we add to this the non-functioning ventilation in the bathroom, toilet, kitchen, then it is not difficult to understand why mold has settled. In winter, the walls freeze and water vapor begins to condense on the inside.
  5. . This, of course, only happens due to gross violations during construction. Insufficient thermal insulation or its complete absence of walls and all structures of the house.
  6. If, when installing new windows or during their operation, cracks form on them, it means that penetrating moisture will definitely get inside the room.
  7. This also applies to window sills.
  8. If even minor microcracks have formed on the walls of the house, not to mention cracks, moisture will easily penetrate the interior surface of the apartment and create a favorable environment for mold to grow. Miscalculations and errors in the repair and construction of a house.
  9. When insulating apartments improperly, owners or careless workers shift the “dew point”

i.e., the meeting place of cold and warm air.

Insufficient roof sealing.

How to stop the spread of mold?

For basic mold cleaning, Reid says his company uses the herbal manganese thyme, which is commonly used in hospitals. Black mold, which can permanently damage your health, often has a slimy, shiny outer layer that may have a green sheen, according to life science consultants and technicians.

Do this to create unbearable conditions for mold to thrive, first of all:

  1. Use an air ionizer or UV lamp if you have one.
  2. In warm weather, open all the windows in the apartment. Draft and ultraviolet light are especially harmful to mold. In cold weather, organize forced ventilation in the kitchen and bathroom. Install a good fan in the exhaust hole so that it draws out moist air faster, and ventilate the apartment more often.
  3. Mold lives and reproduces well at 20–23ºС. At a higher level, its development stops. This means that you need to make the air dry, and for this you need to additionally warm up your home. Any heating electrical appliances are suitable: air heater, household heaters, hair dryer, oil battery, etc.
  4. It is necessary to remove all possible sources of dampness from the apartment: when cooking, close the kitchen doors and, if not, install a hood, replace broken plumbing fixtures.

Do not dry clothes in the apartment, clean the bathroom more often using antibacterial agents, etc.

How is mold harmful to humans?

Mold is a type of dangerous microorganism, popularly called simply fungus. These microscopic fungi are very toxic and allergenic. Their spores are practically invisible and therefore doubly dangerous.

Experts treat black mold by exploiting the space, using high-powered fans, and wearing respirators and biosafety suits, usually when occupants leave the home. Controlling the humidity inside your home is key to preventing mold from forming. Check for leaks under sinks and in crawl spaces.

Mold produces toxic toxins (aflatoxins) that enter the body through the respiratory system and skin.

Accumulating in the body, they will inevitably lead to many diseases:

  • allergic;
  • bronchial asthma;
  • tracheitis, pneumonia;
  • constant headaches;
  • loss of strength;
  • nosebleeds;
  • sinusitis;
  • aspergillosis;
  • weakened immunity;
  • skin rashes, etc.

    Cavity film can sometimes occur due to water condensation when outside air contacts the cavity side of a cooled interior surface. This is a particular problem when rooms have impenetrable walls such as vinyl wallpaper. These impermeable wall coverings trap moisture between the trim and the drywall. Moisture from outside air naturally passes through the building's outer shell and can condense on the cool adhesive peck. For this reason, vapor barriers should be on the warm side of the wall and should not trap moisture in the wall.

With prolonged exposure, irreversible processes in the body may well begin:

  • oncological diseases;
  • internal bleeding;
  • kidney and liver damage;
  • emphysema, etc.

How to remove mold from wallpaper?

Remove mold using a respirator; if not, use a gauze bandage. And protect your hands with gloves; clothes should also be soaked immediately after use and washed well.

Another cause of cavity mold is maintenance leaks. System leaks, such as dripping pipes, may not always become obvious. Slow leaks are especially dangerous because they significantly increase moisture in the wall cavity without immediately causing visible damage to the outside.

Molds are generally not installed on wood surfaces after brief exposure to water. All woods contain natural chemical defenses against fungal attack. If, however, damp conditions persist for longer periods of time, then mold contamination is inevitable.

Before starting work, you need to ask yourself a few questions and answer them honestly:

  1. Can I cope on my own, or is it better to immediately seek help from professionals?
  2. How badly the wallpaper was damaged.
  3. What products should be used and how many times.
  4. If the type of wallpaper is different, how should you remove mold in different ways?
  5. What needs to be done to prevent mold from appearing again.

    Measures to prevent mold in the home

    Once mold has established itself in a wall cavity, it will not continue to grow if the cavity is dry. Drying the wall cavity thoroughly will prevent mold from spreading. The degree of pollution will not decrease, but it will not increase. Forms are reproduced through production large quantity dispute. Mushroom spores are designed to withstand long periods of time in stagnation and are also resistant to drying. If the cavity mold is of the toxic type, the toxins are contained in the fungal hyphae and the spores will remain stable for very long periods of time.

If you are determined to deal with the problem yourself, and the wallpaper is not badly damaged, the affected area is small. This means that you will find answers to the remaining questions in the test below.

Folk remedies

If you decide to do without chemicals, be patient because it may require repeated treatment to obtain a positive result:

Effect of thermal insulation on cavity mold



Commonly used insulation in wall cavities increases the internal surface temperatures of the wall, which reduces the likelihood of internal surface mold, mildew and condensation. Side effect The use of thermal insulation is that it also reduces heat loss from interior spaces in wall cavities. This causes the temperature in the wall cavities to decrease, increasing the likelihood of latent condensation.

  1. Sodium bicarbonate or simply baking soda - it is completely safe and does its job well.
  2. Prepare the solution: dissolve 1–2 tsp in 200 ml of slightly warm water. soda Using a soft sponge, carefully remove the plaque; it is not necessary to rinse off. Soda will be able to protect the wallpaper from fungus for some time. 9% vinegar neutralizes the fungus - just pour undiluted vinegar into a spray bottle and spray on the infected areas. After a few hours, wipe the surface
  3. clean water and ventilate your home.
  4. Hydrogen peroxide - has a strong whitening effect, so test it in an inconspicuous place. Like many antifungal agents, they contain chlorine, but are not as toxic. Although it will be difficult to get rid of the suffocating smell later. They can only be used to treat wallpaper that is washed. Dilute with water 1:10, moisten the sponge and wipe off all moldy areas. And then rinse with regular laundry soap and rinse again with clean water.
  5. Some other effective remedies are a weak solution of potassium permanganate, alcohol-containing compounds, essential oils also have antibacterial effects: lavender, rosemary, tea tree, etc.

Chemicals

Nowadays you can find many high-quality fungicides in a hardware or hardware store. Just remember to read and follow the instructions before use. The main thing is not to forget about safety precautions. If there are children or animals in the house, be sure to remove them from the apartment during treatment. Because it will take several days. Work well:

Water vapor first condenses on the "back side" of the plywood or fiberglass panels. As the value of insulation increases in wall cavities, there is also the potential for latent condensation. Latent condensation can be controlled by one or two of the following strategies.

Wall Cavity Inspection for Mold



  • Reducing the flow of moisture into wall cavities.
  • Increasing the temperature of the first condensation surface.
If wall cavities need to be inspected for mold, this must be done with caution. A gradual approach to opening walls is highly recommended. A small portion of the wall needs to be exposed and mold is observed, which can easily be put aside and covered.

Features of removing mold from different types of wallpaper

It is necessary to understand that wallpaper may also react differently to different treatments. Some wallpaper will change color, others will withstand removal without being harmed at all. Thick and non-colored wallpaper can be subjected to strength tests, but thin colored wallpaper is better to be removed immediately and replaced with new ones.

An indoor air quality specialist evaluates the presence of mold in wall cavities by taking a sample of air from the wall cavity. Samples can either be assessed for the presence of fungal spores or for the presence of volatile chemicals produced in the mold. Boroscope inspections of wall cavities through a small opening are also very common.

Once contamination of the wall cavity has been confirmed and extensive several approaches are available. The preferred option is always to remove the water damaged sheathing, curing the shape and thoroughly cleaning the wall cavity area. For creating controlled conditions An airtight housing design is required to clean the mold. During the removal operation, the mold is removed from the wall cavity, which is then sterilized, mycotoxins are neutralized, and the cavity is dried.

If the mold was easily washed off at first, but returned after a while, it means that the walls under the wallpaper are also affected.

And the fungal colonies are not completely destroyed. This means that you need to start removing the wallpaper, disinfecting the walls and gluing new wallpaper. Before treatment, it is recommended to test the effect of the solution you have chosen on an inconspicuous, small area. If the test was successful, you can safely begin removing the mold; if not, refrain.

Try a different method or buy new wallpaper and start renovating.

If opening the cavity is not practical for any reason, fumigation, gas ozone sterilization, and mold sealing can be used. This approach does not actually remove the mold from the cavity, and the potential for contamination of the interior remains.

White vinegar works wonders for removing mold. White vinegar helps remove mold and avoid chemical safety issues. Mold, especially the nasty black mold, causes problems ranging from just plain bad to allergic reactions and sometimes an asthmatic response, which can be fatal for some.

  1. Insufficient access to fresh air. This is possible when installing plastic windows, the design of which does not provide for a forced ventilation system.
  2. Arrangement of a basement, during the construction of which a full-fledged ventilation system was not created.
  3. Poor quality and ineffective waterproofing of external walls.
  4. Lack of waterproofing of joints between slabs.
  5. The location of the apartment is on the top floor of a building where the roof is leaking and moisture penetrates into the room, saturating the seams and joints between the panels.
  6. Current repairs or recently completed finishing work, which caused high humidity in the room.
