What substrate is blueboard used for veneer plaster?

• A. Cement board
• B. Blueboard or gypsum board
• C. Wood lath
• D. Metal lath

Answer: (B)

Blueboard is a plaster base specifically made to receive veneer plaster. Its surface is engineered to bond well with plaster while controlling absorption, which helps the plaster cure evenly and resist cracking. Veneer plaster is applied in thin coats over this backing, usually with a bonding agent, forming a smooth, durable finish. While cement board, wood lath, or metal lath are used in other plaster or tiling systems, the standard backing for veneer plaster is blueboard or gypsum board because they provide the proper surface texture and bonding for the plaster to adhere effectively.
