In many new home renovations, a new type of insulation wall is commonly used. However, this type of wall is prone to cracking of latex paint. According to analysis, this cracking is caused by cracks in the walls of the cement or cracks in the joints of the wall insulation panels, not the quality of the decoration. Relevant experts proposed the following governance programs:
First, after the wall surface has been cleaned up, first attach a layer of Dacron cloth, kraft paper or newspaper on the wall, and use the tension of the fiber to ensure the integrity of the latex paint film. This method is relatively simple and easy, but the effect is general.
Second, remove the insulation board on the surface of the wall, or remove the cement wall. Install a layer of gypsum board or five PCT board on the outside of the insulation layer, and then paint on it. This method can remove all irregular cracks, but the cost is high and construction is difficult.
Third, use a flexible decorative material. At present, there is a kind of elastic putty on the wall surface treatment that can make up for the wall crack problem to some extent. Nippon Paint's "three in one" can play a role in covering the small cracks on the wall.
