Ok I got a deck built with treated yellowwood pine last July. I know I should of stained sealed it before now but haven't. It dosent look too bad just has a grayish look and looks like it NEEDS some uv stain/sealer. I have a pressure washer and have used Jomax cleaning homes etc. so what do you guys reccommend doing? Cleaning the wood etc. then what kinda sealer stain would you use? Any recommendations would be greatly appreciated. My deck gets full morning and early afternoon sun.
