1. After the wall surface is cleaned, first attach a layer of Dacron cloth, kraft paper or newspaper on the wall surface, and use the tension of the fiber to ensure the integrity of the latex paint film.

At present, on the wall surface treatment, there is a kind of “elastic putty†that can make up for the wall crack problem to some extent. Nippon Paint's "three in one" can also play a role in covering the small cracks on the wall. However, these materials have less "elasticity" and do not work on cracked walls. 4, some consumers simply remove the wall insulation. Although this method can be used once and for all, it will reduce the insulation and thermal insulation properties of the wall, so it is not recommended.
