Which factor is a legitimate consideration when choosing gypsum board for high-traffic interior spaces?

• A. Finish compatibility, board thickness for rigidity, moisture-resistance variants, and applicable code requirements.
• B. Color of the board.
• C. Brand popularity.
• D. Price alone.

Answer: (A)

Choosing gypsum board for high-traffic interior spaces focuses on matching durability and performance with the environment. Finish compatibility matters because the finish system you plan to apply (paint, wallpaper, textures) must adhere properly to the board and its joints without cracking or telegraphing through. The board thickness for rigidity is key: thicker boards resist bending, denting, and impact better, which is important in busy corridors or public areas. Moisture-resistance variants are worth considering in spaces where humidity or occasional moisture exists, since MR boards resist swelling and mold more than standard boards. And you must meet applicable code requirements, since fire ratings, sound control, and other code-driven specs determine which board types are permissible in a given space.

Color is cosmetic and does not affect performance, brand popularity is marketing rather than a guaranteed performance factor, and price alone ignores the necessary performance and code considerations.
