If the adhesion of gypsum mortar to the wall surface is insufficient, the wall surface is easy to empty and peel. At this time, the interface agent must be repainted to make it have strong adhesion on the wall. Not only can it improve the adhesion of the wall, but also it has waterproof effect because of its high water resistance. In the specific operation process, we must pay special attention to using the correct operation method, otherwise, incorrect operation will also cause damage to the wall.

The paint on the wall is divided into two parts, one is to brush the bottom and the other is to brush the surface. But many people have a misunderstanding, that is to say, it doesn't matter if you don't apply primer. This is wrong, because the primer can resist alkali sealing and protect the top coat. The primer should be brushed not only, but also carefully. Primer should usually be applied three times. The method of brushing the surface layer with a brush is roughly the same as that of brushing the primer. The biggest difference is that the finishing layer only needs to be brushed twice.
