Leveling gypsum is a wall leveling material made of phosphorus building gypsum as the main cementing material, mixed with fine aggregates and additives. The material has the characteristics of high bonding strength, no cracking, no hollowing, no sagging during construction, easy leveling, easy forming by lifting angle, saving time and labor, less secondary repair, etc. It is non-toxic and harmless, and belongs to green environmental protection materials.
Leveling plaster is mainly used in the decoration and decoration process. The wall and ceiling are roughly leveled with leveling plaster. Plaster leveling is generally applied after the wall is painted with interface agent and before the putty is scraped. Especially for caulking, filling holes, straightening of yin and yang angles, etc., it is very effective for leveling phosphogypsum - generally used for leveling walls below 5mm.
