Polyvinyl alcohol powder (PVA) is used in various dry powder putties in powder chemical building materials, additives in dry powder mortars, tile adhesives, plaster adhesives, etc., which can effectively increase the adhesion and flow of cement and mortar It can slow down the drying time of cement surface, increase coating adaptability, and prevent cement coating from cracking. It is suitable for the pasting of walls, ceilings and tiles. The method of use is simple and the effect is good.
