## Description

Prime Unicorn Flooring Underlayment 300 SF: desertcart.com: Tools & Home Improvement

Review: Good quality - Worked great floor came out amazing
Review: Nice heavy roll of soft underlayment. - This product is 300 ft² of soft, black, underlayment to be placed down on the floor before any flooring choice. It provides a good seal to protect the wood or concrete underneath, and it also adds a little softness to the people stepping above, even if hard tile is to be placed on top. We ended up using this to completely gut and redo a bathroom in our house. It was easy to use, in fact all underlayment is a very simple job to do. But it maintained a tight seal over the bare wood that was left under our floor. It installed properly without any lumps or any adjustments needed once it was set down. It was a great start to ultimately having the tile placed above it, and definitely helped with making the floor a little more secure, as well as sound and heat proof. Instead of getting a huge draft in there, especially when in the shower, for some reason it helps trap the heat in just a little better. Overall, this roll of flooring was successful and continues to hold strong, even when put in by a complete amateur like me!

### ⭐⭐⭐⭐ Worked Out Fine for Me
*by B***9 on March 13, 2024*

The quantity of this roll is awesome. It is easy to work with. Requires a sharp pair of scissors or box cutter. I was told by the person showing me how to do the install, that this is the most thin underlay material they have seen or used. I had one rip and it was my own fault. I would purchase this again.
