Sand controls the shrinkage, porosity, strength and adhesive properties of plaster. time is the time when the paste starts losing its plasticity. joints properly raked. following procedure is adopted: The procedure It affects the adhesion of paint with wall surface. 3. Plastering is the method of covering rough surfaces and uneven surfaces with plastic materials known as plaster or mortar to achieve a uniform, smooth, regular, clear and durable surface.
