My deck is looking aged. Do I have to treat it, or can I let it go natural?
A natural deck will ultimately turn gray as it absorbs ultraviolet (UV) rays from the sun. You’ll probably be happier if you treat it. First, test to see if there is any residue from previous treatments in the wood by dripping some water on it on a dry day. If the water beads up, the previous treatment product is still in the wood. You must strip off any old finish, then treat the wood with a product that will keep out moisture.
