Gypsum Plasters can be applied directly to brick walls, concrete blocks, or RCC surfaces.
Gypsum Plasters usually come in ready mix bags. Extract the powder in a dry vessel and mix it with water. The mixture has to be stirred for 2-3 minutes. Check the thickness of plaster that needs to be applied on the wall. It should not be more than 13 mm. Apply Gypsum plaster to solid surface with firm pressure.
As the plaster stiffens, carry out further flattening. When the plaster is sufficiently firm, scour the surface with sponge float & water as required. Trowel the surface progressively to get smooth matt finish. Finish surface should be protected from continuous exposure to moisture. Prolonged or repeated exposure to moisture may cause a loss of strength and/or adhesion.
Painting work should be only be started once surface has becomes complete dry.
