Plaster of Paris and Cement Fiber Plaster or simply plaster, is a type of building material based on calcium sulfate hemihydrate, nominally (CaSO4)2.H2O. It is created by heating gypsum to about 150°C. When the dry plaster powder is mixed with water, it re-forms into gypsum, initially as a paste but eventually hardening into a solid. The structure consists of sheets of Ca2+ and SO42- ions held together by hydrogen bonds in the water molecules. The grip between these sheets is easily broken, so plaster is fairly soft. Plaster is used as a building material similar to mortar or cement. Like those materials plaster starts as a dry powder that is mixed with water to form a paste, which then hardens. Unlike those materials, plaster remains quite soft after drying, and can be easily manipulated with metal tools or even sandpaper.Features of Balajee Plaster of Paris :
