What materials do plasterers use?

A plasterer works with a variety of materials to plaster interior and exterior walls, including clay, gypsum, lime, sand, horse hair, and cement. Each plastering material creates a slightly different appearance but works similarly. A plasterer mixes the contents with water before applying the paste to the surface of the walls, which usually requires several coats during the lath and plaster process. Although drywall is now more popular than plaster finishing, plaster is still commonly used for its durability and decorative benefits.
