I honestly would find the best floor finisher in your area and ask what they recommend for protection. My floor finisher said to not put any rubber back rugs on the floor and also plastic floor protectors. Now, I live where it is humid during the summer and that may be the reason as they might trap moisture close to floor. He used several coats of urathane floor finish and his recommendation was to have hime come back every 7 years and do a lite buffing and reapply the finish layers.
