Question: Will Clear Sealers Prevent Graying?
My Pro Advice On Clear Sealers
No, a clear sealer without any pigment will not prevent UV oxidation and will gray your wood in a matter of months. If you want to prevent graying of your wood, it is best to use a Semi-Transparent Deck Stain. Semi-transparent deck stains are designed to penetrate your wood grain while enhancing the natural grain based on your chosen color.
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.
Best for Preventing UV Graying on a Deck
We prefer penetrating semi-transparent products with all of these different types of products as they allow the wood grain to show. They offer better-than-average UV protection and can be easier to reapply in the future.

I use Readyseal semi-transparent stain.. would a clear uv resistant sealer on top of it make the horizontal areas last longer? Right now I have to refinish every two years.. with the stain looking its best the first year. it’d be nice to make it last at least 4-5yrs, snd have it looking the same as the first year for a few years. Thanks!
No, and you cannot add a sealer over a deck stain. It will peel if you do this. Nothing will last 4-5 years on a deck but there are many better brands than Ready Seal. Ready Seal has known issue with fading fast:
