What is the difference between interior plaster and veneer plaster?

• A. Interior plaster uses cement/lime or gypsum binder; veneer plaster is a thin gypsum-based finish applied to blueboard or gypsum board
• B. Veneer plaster uses wood fiber
• C. Interior plaster is for exteriors only
• D. Veneer plaster is thicker than interior plaster

Answer: (A)

The difference hinges on thickness, backing, and binder: interior plaster is the traditional built-up plaster that uses cement-lime or gypsum binder in multiple coats to form a thick, durable surface. Veneer plaster, on the other hand, is a thin gypsum-based finish coat applied over a rigid backing like blueboard or gypsum board, providing a smooth surface with much less thickness. That’s why this description fits best: interior plaster uses cement-lime or gypsum binder, while veneer plaster is a thin gypsum-based finish applied to blueboard or gypsum board. The other statements don’t fit because veneer plaster isn’t made with wood fiber, interior plaster isn’t only for exteriors, and veneer plaster isn’t thicker than interior plaster.
