What are the two main benefits of applying a textured finish to gypsum board surfaces?

• A. It increases moisture resistance and decreases brightness
• B. It provides decorative beauty and effectively obscures minor surface imperfections
• C. It reduces cost and adds weight
• D. It increases rigidity and reduces finish quality

Answer: (B)

The main idea is that a textured finish on gypsum board surfaces serves two practical purposes: decorative appeal and hiding minor surface imperfections. Texturing adds visual interest and style to walls, giving them character and helping light interact with the surface in appealing ways. At the same time, the pattern and variation in texture mask small flaws such as joint lines, trowel marks, or slight irregularities in the board surface, so the wall looks even and smooth from a distance.

Moisture resistance and brightness aren’t the primary benefits here. Texture doesn’t inherently make gypsum more moisture-resistant, and brightness is driven more by paint choice and lighting than by texture. So, the two main benefits—decorative beauty and concealing minor flaws—best explain why textured finishes are used.
