I needed a cheap but quality underlayment to lay under my new tiles for a 300Sq ft room. I checked big box stores and it was expensive for the amount I needed ($300) so I found this on Amazon, read the reviews and decided to go for it! It was way cheaper too! Works perfectly and did the job! Highly recommend!!!

This underlayment worked well for what we needed to do. Our subfloors are leveled and no moisture came out for our moisture test. If it wasn't leveled and had moisture issues, this may not work well. It is easy to install, just place it and tape. But try not to step on it or hit it with the laminate floor planks, it will rip easily. Put tape on it or replace it should fix the problem.

Reviewed in the United States on January 24, 2024

Not the thickest material in the world, but it gets the job done. Just enough for a 10 x 10 room. I wish they would sell these at 110 or 120 ft.², because for a 10 x 10 room you often have a closet or you just need a little extra material to work with. You might end up having to order two rolls. 100 ft.² makes sense as a sales unit, but if you do a lot of DIY, you know you always need a tiny bit extra and it would be more practical if they sold it like that. I needed to put in a floor for a small room on a budget and this stuff did the job.

I felt it was a little expensive at $18 but it really worked for my indoor outdoor carpets that are on sand/dirt to help keep them from getting muddy and it's easy to blow the sand off when you separate them. Won't be buying it again unless the price goes down
