I have a large deck having 2X10"'s as flooring. The deck is about 27 years old and the boards, which are pressure treated pine, are in bad shape. I have decided to replace them with identical sized boards and had a crazy thought. What if I bought a planer and resurfaced the boards to reuse? Would the chemicals left in the boards be a hazard in planing? Would the boards retain their rot resistance? I welcome all comments and suggestions. Norm or Tommy, do you have any thoughts? Thanks.
