Gypsum hand plaster-Siva

Gypsum based hand plasters are used for smaller areas as well as during renovation. They are stirred either by hand or with a machine and applied manually, usually with a trowel. Gypsum based hand or bonding plasters are less delayed than gypsum based machine plasters. They are usually made up of gypsum hemihydrate, special additives, perlit and calcite.
