Putty is a kind of substrate used for wall repair and leveling, which lays a good foundation for the next decoration (brushing and painting wallpaper). The putty is divided into two types: the inner wall and the outer wall. The outer wall putty should resist the wind and the sun, so the glue is large, the strength is high, and the environmental protection index is slightly lower. The internal wall putty comprehensive index is good, healthy and environmentally friendly, so the interior wall is not used externally, and the external wall is not used internally. Usually the putty is gypsum or cement based, so that the surface roughness is easier to bond firmly. However, during the construction, it is necessary to apply a layer of interfacial agent on the base layer to seal the base layer and improve the adhesion of the wall surface, so that the putty can be better bonded to the base surface.
