What type of gypsum board is recommended for use as a base for an interior veneer plaster finish?

• A. Purple board
• B. Green board
• C. Blue board
• D. Regular gypsum board

Answer: (C)

The recommended type of gypsum board for use as a base for an interior veneer plaster finish is blue board. This specific board is designed with a special moisture-resistant paper that enhances adhesion for plaster applications. Its surface provides an excellent foundation for veneer plaster, which is a thin layer of plaster that can be applied to achieve a smooth and durable finish. Blue board is specifically formulated to be more compatible with plaster than other types of gypsum board, allowing for optimal bonding and minimizing the risks of cracking or peeling over time. This makes it the preferred choice for projects where a high-quality finish is desired. Other options, while different, either do not offer the same level of compatibility with plaster (such as regular gypsum board) or are designed for different purposes (like green board, which is moisture-resistant but not specifically for plaster). Purple board, often used in moisture-prone areas, is also not specifically intended for veneer plaster applications. Thus, blue board stands out as the most appropriate option for this specific use case.
