How to solve the moldy wall in winter? Whenever the walls of my house are in winter, especially the heating.

If the wall is moldy in winter, the solution is to scrape off the moldy wall skin with a scraper, which is larger than the moldy area, and then ventilate and air dry to ensure that it is not wet, which is conducive to the later repair work. ?

Clean up the wall with the wall skin scraped off, apply the putty powder, and then apply lime after the putty is dry. Lime can absorb water and keep dry, then apply waterproof paint and latex paint, and finally polish the wall again.

In addition, in winter, it is necessary to take thermal insulation measures for the wall to avoid further occurrence. One is to do the internal insulation of the external wall, and the other is the most insulation coating.

Extended data:

There are many reasons why the bedroom wall is moldy, mainly the outer wall. The so-called external wall reason is that the external wall insulation is not done well, there is water seepage or cold ventilation, and there is rain and snow on the external wall in winter;

As time went on, it slowly penetrated into the wall. When heating in winter, the indoor temperature rises and the water vapor saturation is high. But the wall is not well insulated, so the wall is cold, and water vapor will crystallize into water droplets on the wall. When the wall is wet, it will look moldy.

The moldy wall at the background wall of the bed belongs to the phenomenon of external wall ventilation, so it will only appear in winter and will not show in other seasons.
