XFasten Waterproofing Membrane Sheet, 6” x 75 Ft Shower Waterproofing Membrane Tape for Underlayment Tile, EPDM Underlayment, Cement Board Tape

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.

Works great with Redgard

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.

I had good experience using this tape,Waterproofing a large shower with a tall niche' I had been using a cheap paper tape that ripped far too easy, Especially in the corners where you need it the most ! This tape is more like cloth and will not tear easily. I found it worked best if you coated the surface underneath, Using that as a stickem, Apply the pre cut length over that and brush/roll on more till the waterproofing is soaked thru. The only thing I didn't like was you cannot fold it in 1/2 and form a crease to put in the corners, But its really not that kind of tape. Highly Recommended !

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

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.

What can I say, it's what I needed. It worked and it didn't break the bank. If I might suggest something, if you have never used this I have some advice. I had never used it paint on membrane, because I couldn't find it in the stores I frequent. But I decided to start. My suggestion is to not over lap tape regardless of how much of a pain it is to get the exact measurement of the seem tape. For example; you do your corners, and then you have a horizontal but joint, start your tape at the edge of the corner tape and then make your run. Reason being is you paint membrane on the joint, then apply tape, then paint membrane on over the tape. So, if your tape overlaps, you have a pretty good bulge preventing a professional looking tile job. Learn from my mistake. I was lucky and the tile that the customer chose to use was so dang odd ball and was so many different thicknesses and they wanted that look that you can't tell that the tile going over those bulges are sticking out a little.

Good

It does the job and much cheaper than competitors. Easy to install. You can cover the corners of an entire house and probably you'll still have some left.

Used it to waterproof a window casing prior to laying tile. First rolled a thick coat of liquid membrane, then layed the fabric over the gaps. Then rolled on another coat of membrane and soaked the fabric thoroughly until I couldn't see any white fabric through the membrane. Finished with another coat of membrane and let cure for the night. Neat result.

holds water proof memebranes very well; cheap and effective; if you do it properly you will not have a drop of leakage. The job of this membrane is only to hold your waterproof membrane (Red gard, etc).

Used this with red guard. Did the corners and any joints, super easy to use. Very happy.

I used it on a plywood deck under the EVA foam decking as a water barrier and deck protection with resin.
