Which plastering method uses gypsum board backing with veneer plaster?

• A. Lath and plaster
• B. Plaster over gypsum board
• C. Traditional stucco
• D. Gypsum board alone

Answer: (B)

Veneer plaster is a thin plaster finish applied over a gypsum board backing to create a smooth, durable interior surface. This method uses gypsum board as the substrate and then applies a veneer plaster coating in thin coats to achieve the final finish. It’s different from lath and plaster, which relies on lath behind a thicker plaster layer; traditional stucco, which is exterior cementitious plaster; and gypsum board alone, which is drywall without a plaster finish.
