Increasingly, plasterers apply insulation to the exteriors of new and old buildings. They may apply an additional coat of this material with a decorative finish. Plasterers sometimes do complex decorative and ornamental work that requires special skill and creativity. For example, they may mold intricate wall and ceiling designs. Following an architect's blueprint, plasterers pour or spray a special plaster into a mold and allow it to set.
Workers then remove the molded plaster and put it in place, according to the plan.
Sometimes plasterers work on scaffolds high above the ground. Plastering is physically demanding, requiring considerable standing, bending, lifting, and reaching overhead. The work can be dusty and dirty, soiling shoes and clothing, and can irritate the skin and eyes. Most plasterers and stucco masons work on new construction sites, particularly where special architectural and lighting effects are part of the work. Some repair and renovate older buildings.
