Quality, Performance!
Perfect for the job! I'll be ordering another roll for the backsplash! This roll is for a new pony wall that will give the stove area a backsplash as well! If you're getting ready to do a remodel tiling project in an area exposed to moisture/water and demoing the sheetrock to add Green Board is not feasible then here's the solution! I Highly RECOMMEND to all DIY'ers as an inexpensive option with the same quality as the $300.00+ price from other MFG's!

Doesn’t have all the lines and namebrand on it.
For the price and how thick it is . Well worth it the 1/4 of price . I was fine waiting two days to get it.

I recommend
This works very good and I'm sure it will keep my bathroom waterproofed. However, I can confirm that the fiberglass/material does or can delaminate which can be frustrating. Schluter brand is probably the best, but they are also overly proud of their products and have priced them accordingly. This brand will do the same as Schluter.

Texture.
Didn't use it yet, but it's almost the same quality like the brand name ones. The texture feels ok, I am happy with it.

Good moisture prevention under flooring
Great use beneath my LVP flooring in our bathroom remodel. Guaranteed to prevent moisture on our second floor, which is our kitchen ceiling below. Easy to install, and somewhat sound deadening are extras I hadn't thought about. Love it.
