Fungus on the slopes. How to eliminate

Blackening of slopes is a common problem of prefabricated houses and buildings, which require repair as a result of long-term operation. There is a solution.

To begin with, a humid environment is necessary for the development of a fungus.

Causes of fungal infection:

  • insufficient ventilation of the room;
  • freezing of joints between the window frame and the wall.


The first is eliminated by changing the ventilation mode. In this case, it is better to put the windows in the mode of “slit airing” – turn the handle 45 degrees. This mode is provided by a special window fittings and gives air exchange, which allows you to eliminate excess moisture, while not too cooling the air inside the room. If this is not enough, then instead of a ventilation grate, you should put a small fan to accelerate the air flow.

If you have already strongly developed a fungus, then a set of measures should be taken to clean it from the wall, since the mold spores deeply saturate the porous structures of building materials. Detailed information on how to do this can be easily found on the Internet.

In the second case, the excessive overcooling of the inner surface of the slopes occurs due to insufficient heat resistance of the joint between the frame window and the wall, as a result of which the surface of the internal slope is supercooled and condensation occurs on it. Excessive humidity is the cause of fungus formation. In this case, it is necessary to warm the slopes from the outside with polyfoam or extruded polystyrene foam with a thickness of 2 cm or more. This will avoid unnecessary overcooling of the surface of the internal slopes. But do not forget that blackening itself will not evaporate and should be removed.

It should be noted that the fight against fungus on the slopes is a complex of measures: from changing the ventilation mode and surface treatment with special means to sealing and insulating external slopes.

What means to solve the issue of mold on the slopes – the choice of each particular homeowner, and ours – just a hint. And let your home be warm and cozy.
