Easy to use and good for all LVP and wood.

Would Recommend

This came in a large well sealed box. It is lightweight and easy to transport. We are building a home and using LVP and also some engineered wood. It is easy to use and rolls out easily. It is a good weight for what we need. It comes in a large roll so won't have to get different rolls as we go along to put down the flooring. We have just started but impressed with this backing.

Doesn’t work as advertised!

Would Not Recommend

Great Product as expected

Would Recommend

This product is what is stated to be. Make sure it is securely placed on the floor with no imperfections on the floor itself. This will all carry through to and uneven install of the flooring.

Good Moisture Barrier

Would Recommend

Product is effective in providing a cushion and vapor barrier for my vinal plank flooring. Performed as designed. This made laying down the flooring super easy. I used a razor knife to cut it and it was very easy to size out the room. This moisture barrier is actually thicker than it appears, providing more cushion and sound dampening than I had anticipated. It is easy to lay and cut, however, it does take two people to join pieces using the adhesive strip on the product.

Good for noise reduction and moisture barrier

Would Recommend

Good underlayment for imperfections and a moisture barrier. The product is 2 mills. Over 3.25 wide and 135ft in a roll. Great fit laminate and wood floors with a foam to help reduce noise. Product is easy to use and can be fastened down with a stapler or a tacker.
