What is a common cause of finish failure in wood structures?

A common cause of finish failure in wood structures is ultraviolet exposure and abrasion. Wood is inherently sensitive to environmental factors, and prolonged exposure to ultraviolet (UV) light can lead to degradation of finishes, causing them to break down, fade, or peel. UV rays can penetrate the finish and damage the underlying wood, resulting in a compromised protective layer.

Abrasion, on the other hand, refers to physical wear and tear that can occur due to friction or contact with other surfaces. This can result in scratches, scuff marks, or removal of the finish, allowing moisture and other harmful elements to reach the wood itself and lead to further deterioration.

Choosing this option highlights the importance of protecting wood structures from both UV radiation and physical damage to maintain their finish and overall integrity over time.
