Variety of types of home mold

Cladosporium - at first, a dull, undemanding mold fungus grows rapidly into a colony and changes its color to a very dark one. It is often found in dirty refrigerators, settles on flowers, likes to sit on the wallpaper.
Aspergillus - often affects different foods. This mold fungus can live in very harsh environments, such as brickwork.

Spotting and killing white mold

Mildew with white color on plaster in your home is more difficult to see. More often, it is better to judge the infection of an apartment with white mold by a white bloom on the ground in flowerpots with plants. Why white mold appears in the walls of the house, no one knows. The owners of such dwellings should be wary at the sight of suspicious white dots on the walls of an apartment or some other surface.

In a cellar or basement

Unlike other places in a country house, the appearance of fungus or mold in the basement can occur for the following reasons:

Water formation around the foundation;
Lack of ventilation in the room;
Improper planning of the area around the house;
Lack of insulation in the attic and walls, which leads to the formation of condensation and freezing of the enclosing structures.

Mold in the basement
To fight the fungus in the basement, they begin with the insulation of the walls and floors.In old buildings, waterproofing must be restored. To prevent the appearance of fungus, you can periodically ventilate the room, which will help remove accumulated moisture. The second option for combating microscopic parasites is the injection of warm air into the cellar. The floor in this room is made of expanded clay or slag.

The surface of wooden products is covered with antiseptics in two or three layers, after which the material is thoroughly dried. It is better to replace the affected wood with a new one, but if there is no such possibility, then at the first signs of exposure to the fungus, the affected areas of the material are scraped off with a sharp knife. The lesions are treated with antiseptics or other chemicals.

Important! If you use chemicals to kill fungus or mold, use protective equipment (mask, respirator, gloves, goggles). Provide a constant supply of fresh air in the room.

Affected wood

Other ways to combat mold and mildew in your basement or cellar:

Table salt is poured into a container placed on the floor, and then sulfuric acid is poured. This mixture will constantly evaporate. The released gases have a detrimental effect on the fungus;
Using white moss powder, which acts as an adsorbent;
Impregnation of affected walls with hydrochloric acid solution. In such a case, you need to take out all the vegetables and preservation from the cellar, and only after that you can begin to disinfect the room. Work must be carried out with thick rubber gloves;
Installation of quicklime containers in the corner of the basement. This substance will pick up excess moisture from the air, depriving the mold of a favorable habitat;
Mold is afraid of diesel fuel, acetic, citric and boric acid.

At home, there is mold on the walls - why?

If mold spores are everywhere, then why does this infection not attack every house or other room? Why does ugly mold appear on the walls in the house? The reasons are different. The point is the living conditions in a single place - for their own comfort, mankind has long been paying a certain price - proximity to fungi. Why do walls in a house get moldy? Because they are also satisfied with the average annual temperature and humidity in the room (18-23 degrees and 50-60% humidity). This is a very comfortable environment for mold to flourish in your home. That is why there are causes of mold on the walls in the house. The more humidity in the apartment, the more real is the possibility that mold will quickly appear on the walls of the house.

However, there are many houses in which there is regularly a fairly high humidity and at the same time mold does not grow on the walls of the house. Why do the walls in a house get moldy in some houses all the time and never in others?

Mold on the walls in the house - the reasons mainly lie in the violation of technologies in the field of construction, for example, improperly laid roofing cake, laying ineffective vapor barrier, and most importantly, poorly arranged ventilation.

Mold on the walls in the house grows due to the lack of a constant saturated inflow of fresh air masses of air, which increases the humidity of the air in the building.

If you eliminate this factor, then the question: "how to remove mold from the walls in the house?" will not torment anymore.

Important! If you run a problem, then the fungus will corrode building materials almost throughout their depth. ... Blue fungus

Blue fungus

It grows on a woody surface in the form of a gray or blue bloom. The danger of blue is that it significantly increases the moisture content of the tree, which soon leads to its destruction. Also, high humidity becomes a favorable environment for the formation of whole colonies of the blue stain fungus.

Important! Pine most often suffers from it.

Rotting fungus

This type of colonies is white and brown, also appears only on wood. When it appears, the walls turn gray, the material decomposes from the inside and loses its strength. There are several types of this rot:

White rot - when it appears, the color of the tree practically does not change.
When brown rot forms, stripes of yellow, brown and black appear.

As a result of the occurrence of such phenomena, the tree begins to bulge and split.

Important! The white mushroom house is the worst enemy of any wooden floor. In a month, he can completely ruin a wooden parquet with 40 mm thick boards. Previously, in case of infection with this mold, houses were simply burned so as not to infect the neighboring ones.

Efflorescence

Efflorescences can also be called very harmful. They spread to bricks and concrete. This fungus appears as a white salt deposit. Over time, it also penetrates deep into the materials and destroys them.

Now take a close look at the mold that has formed on your wall. Considering the above facts, determine which fungus has burst into your house. It is on its type that it depends on what kind of treatment the walls in the apartment will be from fungus and mold.

But this approach not only does not help, but exacerbates the situation, since the fungus feels great in the heat-insulating material.
Or, spotlights are powerful and bright lamps that try to "dry the mold". Fungal spores quickly adapt to new conditions and easily tolerate "drying".Waterproofing over the mold, unfortunately, won't help either. Water will find an opportunity to bypass all the tricks and the mold will "bloom" again.
