    • More flexible than other brands.
Style: 6 Inches x 75 Feet Color: White
More flexible than other brands, so it's easier to do corners. You can put it on with the roll-on liquid waterproofing instead of using thinset. Works as advertised. Happy with this product.

    • excellent product
Style: 8 Inches x 75 Feet Color: White
I build custom showers using liquid waterproofing membrane. I've been looking for a high quality membrane fabric for years. They have been either too stiff or too easy to tear. Not this product. This is by far the best membrane fabric I have ever used. The width is perfect for covering the curb and getting a good flash on change of plane joints. Its a perfect thickness, not too thin as to become fragile and not too thick to add a hump in your corners. This is now my go to for all joints and changes of plane. ... show more

    • Seems to be great alternative to proprietary Custom Bldg. Products' & Laticrete's
Style: 6 Inches x 75 Feet Color: White
I wanted to get the Custom Building Products' 6" fiberglass mesh for a RedGard shower and shower pan I'm building, but the you-know-who orange Big Box store doesn't stock it, so I'd have to find a local Custom Building Products distributor and wait. It's Sunday and I wanted to figure out a supported alternative to RegGard's proprietary fabric. and I want to to get rolling now.. I bought the Laticrete waterproof membrane reinforcement fabric on Amazon, but I wasn't sure if it's compatible with RedGard (i.e. Custom Building Products' product line). I didn't want to run out of reinforcement tape, so I went to buy a 2nd roll of the Laticrete stuff, but noticed xFasten cost half as much! So I bought a roll, decided to compare them and will share what I found with you. Custom Building Products' anti-fracture tape claims explicitly that it is alkali resistant fiberglass. Alkali resistant fiberglass is specifically what Custom Building Products endorse for using RedGard waterproofing membrane over changes of plane. Unfortunately The Laticrete product is not fiberglass or at least makes no mention of it. However xFasten is alkali resistant fiberglass. I compared xFasten directly to the Laticrete fabric, I find them comparable. Both have strong sheer resistance but xFasten *seems* to be stronger. xFasten is softer and more pliable. The Laticrete fabric is a bit more structured/rigid but still basically soft/fiberous and pretty easy to work with. The Laticrete fabric holds creases and folds better, the xFasten fabric is easier to "re-calibrate" on the fly. I personally think all three manf's 6" waterproof membrane reinforcement tape they will do the trick for the task (i.e. reinforcing liquid-applied waterproof membrane at changes of plane), but since I have to get my shower pan inspected by the city, I wanted to be sure I could claim to the inspector if asked that I met the criteria specified by RedGard (fiberglass, alkalai reistant), so went with xFasten instead of the Laticrete fabric. If it was Monday I'd just have called Custom Building Product's support line and asked them if the Laticrete fabric (or xFasten) are acceptable for RedGard. ... show more

    • Great for using on shower project.
Style: 6 Inches x 75 Feet Color: White
Review Image by Southbound
Decided to DIY my shower project since prices were way too high for something I could do myself. Had to redo the shower because the home builder (well, the tile folks who installed the shower), did it incorrectly and we had leaks. I researched how to do the project and YouTube has a lot of good information. I found one video using a product like this with a waterproofing compound so I bought this brand. I used it with AquaDefense and it worked great. I first installed the concrete panels and then used a mesh tape and thinset to bond everything. After it was dry, I applied a layer of AquaDefense and while it was wet, put this material over it. I precut the pieces and had all the cuts for folding and bending already set so the installation was faster. Once this product was installed, I recoated the top to allow it to suck up the waterproofing. After letting it day, I applied a second coat and it worked very well. For those 1 star reviews claiming this isn't waterproof, duh... it doesn't claim to be. This is meant to be used with a waterproofing compound like RedGuard, AquaDefense or others. I didn't find it too thin or too thick. It was perfect for it's intended purpose. ... show more
