No need to bother low quality, construction grade films, which are bothersome and hard to use before the floor is installed. Recommended for use with pad-attached floating floors over concrete or any substrate where moisture is a concern.

Roll the film out and tape all seams for easy installation

Great underpayment for vinyl plank flooring

Our floor turned out great using this vinyl underpayment. It was heavy duty, easy to use with the adhesive strip, and very reasonably priced. We are very happy with how it helped us lay a beautiful floor.
