Plasterers apply coats of plaster to interior walls, ceilings, and partitions of buildings to produce fire-resistant and relatively soundproof surfaces. They also work on exterior building surfaces and do ornamental forming and casting work. Their work is similar to that of drywall workers, who use drywall rather than plaster to build interior walls and ceilings. Plasterers who specialize in exterior plastering are known as stucco masons. There are approximately 49,000 plasterers and stucco masons employed in the United States.
