Gypsum plaster is obtained as a dry powder from partial or complete dehydration of gypsum. Heating forces the water in gypsum to evaporate and produces a fine powder. When this powder is then mixed with water and applied over bricks, walls or cement, it hardens and re-forms to form a smooth surface called gypsum plaster.
Gypsum plastering has received widespread acceptance and adoption as a construction material in the last decade and has been revolutionizing the Indian construction industry. The miraculous properties of gypsum plaster have enabled, in reality, the construction of greener, cheaper and faster buildings.
