Can Clear Sealers Prevent Graying?
No, a clear sealer without any pigment will not prevent UV oxidation and will gray in a matter of months If you want to prevent graying of your wood it is best to use a Semi-Transparent Deck Stain on your deck. Semi-transparent deck stains are designed to penetrate into your wood grain while enhancing the natural grain based on the color you choose.
Note: Stains that are “Natural” in color typically have a tint (not clear) and will enhance the grain like a wet look. Natural tinted stains will provide UV Protection.
