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. Review: More flexible than other brands. - 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. ## Features - MULTI-USE.

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. You can check out the Fiberglass Drywall Repair Tape here: https://www.amazon.com/dp/B07V3LMCDV 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: https://www.amazon.com/dp/B07J1SCSBR 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! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great for using on shower project. *by S***D on July 13, 2020* Decided to DIY my shower project since prices were way too high for something I could do myself.

Happy with this product. ### ⭐⭐⭐⭐⭐ X Fasten Fiberglass Waterproofing Anti-Fracture Membrane Fabric Tape, 6-Inch x 75-Foot *by R***N on July 7, 2021* X Fasten Fiberglass Waterproofing Anti-Fracture Membrane Fabric Tape, 6-Inch x 75-Foot Very excellant for reinforcing seams on the roof, and you saturate with roof (rubbery or latex) compound. The roof product is generally a bit thicker as paint and you paint it on the roof or object to be sealed and then saturate the cloth covering the seam. for clear understanding, there is NO STICKY on this cloth, it is just a cloth, that you use roofing material to attach to the roof. You can kin this to using paper tape when drywalling the seams in your house. The paper tape also has no stickyness to it, you use the wall mud to stick it. This is used to help the roofing material stretch without tearing, thus maintaining the seal on your roof. This is important on an RV because they are moving, seams open and close as you are driving down the road. This works great with products like Kool Seal but any product that you can roll or brush on should work. I also used in on an RV air con COVER thatwas cracking and used this and clear Truck Bed Liner to make it strong again. The Air Con covers are made of plastic, and they are greatly affected by UV light. The covers cost $200 to replace. Putting the Truck bed liner on also protects form Ice hail attacks by the weather. I highly recommend this cloth I do not know the seller and did not receive any money or product for my random review. 210706 1813 ## Frequently Bought Together - XFasten Waterproofing Membrane Sheet, 6” x 75 Ft Shower Waterproofing Membrane Tape for Underlayment Tile, EPDM Underlayment, Cement Board Tape - USG DUROCK Brand Liquid Waterproofing Membrane 1 Gallon --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/63995375-waterproofing-membrane-sheet-6-x-75-ft-shower-waterproofing-membrane](https://www.desertcart.is/products/63995375-waterproofing-membrane-sheet-6-x-75-ft-shower-waterproofing-membrane) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-08-09*
