Depending on the type of job, different materials and tools may be used for plastering. Plasterers use a combination of sand and cement to create a strong base with gypsum and other minerals added for a smoother finish. They also use trowels, hawk boards, and wet stone masonry to apply plaster to walls and ceilings or to fix any imperfections. Plasterers also utilize various adhesives and sealants to ensure the highest quality results.
