Putty is a kind of base material used for wall repairing and leveling, which lays a good foundation for the next decoration (painting and pasting wallpaper). Putty can be divided into interior wall and exterior wall. The exterior wall putty should be resistant to wind and sun, so it has high adhesive property, high strength and low environmental protection index. The comprehensive index of putty for interior wall is good, healthy and environmental protection, so the interior wall is not used externally, and the exterior wall is not used internally.
