Features

6-mil Vapor Barrier

Blocks moisture to protect overlying flooring.

MoistureBlock™ is a low-density polyethylene film that can be used during the installation process where additional moisture protection is needed. No need to bother with large fold out, 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

Wrinkle/Crease Free - No added noise due to wrinkles in film
Easy to Handle Size - Just 30 inches in width, easily rolls out smoothly in small to large rooms
No Wasted Plastic - With its economical size, this underlayment won't be wasted

Thank you for reaching out. This product is not designed to accept adhesive. You will have to check with adhesive manufacturer’s and see if they have any product that will bond to a polyethylene film.

Thank you for reaching out. That is not an approved application and we have no way of knowing if it would work in that setting.

Thank you for reaching out. You will need to use any product that has a vapor barrier to stop the moisture.

Thank you for reaching out. This will be the last product to go down before the flooring.

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.
