YZprism Waterproof Membrane Uncoupling Membrane for Under Tile Underlayment Membrane, Tile Flooring PE Fabric, Waterproof Membrane Shower Membrane for Bathroom Sauna (5inch x 100Ft-42 Sq Ft)

This membrane was easy to install for waterproofing around the shower window sill in my older house. The thickness was adequate for my needs and makes it seems quite durable.

Same quality as top competitors without all the worthless line markings you pay more for. Well worth the money saving. Definitely recommend

Works as advertised.

Price was good, did it's job well, easy to use

Worth the money

Works great a lot better than the shooter. Stuff Materials fairly thick and seems to hold up nicely.

First time DIY shower tiling job. Went with mostly Kerdi products, but the shower is much larger than standard and both due to delivery time and cost, I threw this into my cart. First I did a water test on it and it held up great (cut a piece and bent it into a plastic container and added water, waited a couple days and the membrane barely absorbed any water and none dripped through). Second I decided to only apply this in areas that would not get direct/constant shower spray--that is near the ceiling. It seems to do okay, but after having had experience with Kerdi band, I had an installation technique (firmly running my 4" putty knife along the tape perpendicular to the tape to remove excess thinset and adhere the tape to the wall then parallel with the tape to smooth it out) that just fuzzed up the felt fur. In some cases, the quantity of fuzz made it a little more challenging to notice any bulges or bubbled that needed to be smoothed out. All in all, I am reasonably confident that this will contribute to the water-proofness of my shower because it isn't in critical areas, and I don't regret buying because, due to my inexperience with prepping a shower for tile, I would have used a king's ransom worth of Kerdi band.

I really like this for the value. It is a tad thinner than the Name Brand, for this reason I will use it everywhere except on the floor of a shower. I'll use it for niches, inside wall corners and covering the screws. This is a great way to save $$$. Also, yes you can push air through it, but you can with the name brand too. Its a water barrier yet lets vapor pass through...just like the name brand. It works, have at it boys!
