What Customers Are Saying

This underlayment product is generally effective at providing a moisture barrier and facilitating a smooth installation process. Most users found it easy to work with and compatible with various flooring types. However, some customers reported quality issues, such as wrinkled material at the end of the roll, and concerns about the adhesive system not performing as expected. While a solid choice for basic underlayment needs, the product's value may not align with the features and performance for all customers.

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.

Budget Friendly, Easy Install AND Waterproof seal!

Would Recommend

The Project Source 450 sq ft, 2-in-1 Underlayment is actually a good product and is budget friendly! This underlayment can be used under Laminate or Wood floors. We installed it under Wood floors in our master bedroom. Project Source stepped it up by adding a seal strip (you just peel off the paper and apply the overflap from the adjoining piece which allows for a waterproof seal! It was Sooo easy to use! And it noticeably improved the sound when you walk on the floors. We definitely recommend ...

2 in 1 Underlayment

Would Recommend

This standard foam underlayment was easy to install and provides 2 important features, it provides a vapor barrier and a cushion for the floor I am installing. The plastic that extends out from under the foam in combination with the tape on the opposite side provides a nice vapor barrier. I also added a layer of vapor tape down each seem not because it is instructed but because it adds another layer of protection. I recommend this underlayment.

Easy, peasy, done in no time

Would Recommend

This underlayment came at the perfect time for us. We needed to replace the floor in our bathroom which was 15 years old. So when we saw it was good for moisture which there's always a lot of that in any bathroom, we knew this was just the ticket. After ripping out all the old and cleaning it up. We used the existing plywood floor and put in the underlayment. The sticky strip was a great addition towards what we used with the older floor.ing We had to tape it ourselves. We laid it down and had i...
