01Overview
Calcium Sulfate Hemihydrate，Plaster of Paris
Calcium sulfate hemihydrate (plaster of Paris) serves as the core binding material for finishing and leveling plasters. Upon hydration, it forms a slightly expansive structure that effectively prevents coating cracks caused by drying shrinkage, offering excellent bonding strength, smooth workability, and superior breathability. The standard dosage is 55%-70%; a retarder must be added to extend the working time, and the material requires careful moisture-proof storage to maintain consistent performance.
