Which of the following is a purpose of using finishes on timber?

• A. Protection and aesthetics.
• B. To make wood heavier.
• C. To increase moisture content.
• D. To change wood species.

Answer: (A)

Finishes on timber are applied to protect the wood’s surface and to improve how it looks. The protective role comes from a coating that seals the surface, reducing moisture uptake and guarding against scratches, stains, and weathering, which helps the timber last longer in use or outdoors. Finishes also enhance aesthetics by bringing out the grain, adjusting color, and providing different levels of shine or texture. They sit on the surface and don’t change the wood’s species, nor are they intended to increase moisture content or add meaningful weight. So the purpose is both protection and aesthetics.
