Plaster is a building material covering rough surfaces such as walls, columns, ceilings, and other architectural components with a thin coat of plastic mortar to create a smooth, long-lasting surface. Plaster is a polymeric material that has been coated (i.e., mortar). Plastering is the term for this procedure. Rendering is the process of plastering an exposed surface on the outside.
Mortar is a light mixture of binders (lime or cement) and fillers (sand or broken stones). Good plaster needs to have a proper bond with the masonry surface. Plaster is made from a dry powder combined with water to create a hard but effective paste before being placed on a surface. Ancient civilizations used mud as plastering to create long-lasting, weather-resistant constructions.
