flooring

Post by sivils11 »

We have found an old, VERY old, porch floor under interior tile that we've removed and plan to cover with a plywood floor. As expected in an old porch floor there are gaps between the boards. Our question is, in addition to laying a moisture barrier should we back paint/polyurethane the plywood?
