Hybrid RVP Floor in Wet Areas
You had helped me with a Hybrid floor sometime ago in New Zealand which turned out great. Now my daughter wants me to put a hybrid RVP floor into her bathroom. My concern is she lives in a that is about 40 years old the bathroom subfloor is a patchwork of plywood and I am concerned about using a hybrid floor in a wet area. I was thinking about putting down a layer of polyethylene to protect the subfloor from moisture or am I better off putting down a coat of polyurethane just to seal the plywood? Any advice you have would be appreciated.
