## Questions & Answers

**Q: how well does this work on inside/outside shower corner joints?  Will it easily bed into a 90 /180 degree angle?**
A: Yes. I just used this when waterproofing a shower using Redguard. I first used mesh tape and mortar on all joints and corners ( inside and out). Then used Redguard on all surfaces, with the membrane fabric embedded in all joints and corners. The fabric folds easily around outside and inside corners.

**Q: Can I use this on a previously cracked concrete floor (over which I will pour leveler) before laying down tile to prevent cracking from movement?**
A: Hello EthericOne,

Thank you for sending an inquiry. Yes, indeed! You can use the XFasten Fiberglass Waterproofing Membrane Fabric sheet to prevent the concrete crack from affecting the tile after installation. This Waterproofing Membrane Sheet not only prevents moisture and mold from seeping through, but its optimal thickness can also provide some form of shock absorption to your floor.

Although your is a new and improvised use-case, we are sure that the Fiberglass Waterproofing sheet will be great for your application. However, please note that this is a non-adhesive tape. To make it adhere completely to a surface, you would need to apply a waterproofing liquid membrane to it. However, if you just want a fiberglass sheet that can take care of the crack on the concrete floor and has a pre-applied adhesive, then we would recommend our Drywall Repair Tape. They are made of fiberglass mesh and will also work perfectly in preventing the cracked concrete floor from affecting the newly installed tile.

We hope that we have answered your question, EthericOne. Please don't hesitate to contact us should you have any further inquiries. Have a nice day ahead!

**Q: Do you put this on with thin set or can you use redgaurd to adhere it??**
A: Hello Brandon,

Thank you for that inquiry. We recommend using Redguard or any other waterproofing membrane solution brands to adhere the XFasten Waterproofing to the surface. Our tape is compatible with all leading and known waterproofing membranes. We also offer a larger and wider waterproofing membrane sheet variant that covers a larger surface area, thus making it easier to apply, not to mention much more economical.

You can check out our large Waterproofing membrane sheet variant on the link below:

We hope that we have answered your question, Brandon. Please don't hesitate to contact us should you have any further inquiries. Have a nice day ahead!

**Q: Is this product Adhesive backed??**
A: Hello Ebubba,

As is with all other membrane fabric tapes, the XFasten Fiberglass Waterproofing Membrane has no adhesive in it. It is meant to be used with a substrate for waterproofing.

We hope that we were able to answer your question. If you have any other inquiries, then please don't hesitate to reach out to us through our Amazon storefront. Thank you and have a beautiful day ahead!

Worked on plenty of showers, this is a quality product. Use them in my shower and the 6 inch is wide enough to handle all showers. Will purchase again if and when I run out

### ⭐⭐⭐⭐⭐ Works great with Redgard.
*by E***D on December 6, 2025*

I use this in conjuction with Redgard to make watertight showers prior to tiling. Been ordering it for years and will continue to do so.

### ⭐⭐⭐⭐⭐ Seems to be great alternative to proprietary Custom Bldg. Products' & Laticrete's
*by F***R on February 7, 2021*

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.
