What effect does clear varnish have on timber?

Clear varnish enhances the appearance of timber by providing a glossy finish that highlights its natural grain and color. It also offers protection against moisture, UV rays, and general wear, helping to prevent damage such as fading, cracking, or warping. Additionally, varnish creates a barrier that makes the wood easier to clean and maintain over time. However, it may slightly darken the wood and can require periodic reapplication to maintain its protective qualities.
