Can this tape be used with the Redguard water proofing membrane ?

Asked by: degenerate
Yes. Tape the Durock joints and fill the joints with Thinset mortar just like you would fill drywall joints with drywall compound. Do not use drywall compound or mastic with cement board. After this dries for 24 hours, place a minimum of 2 coats of Redgard onto the joints and all exposed face of the Durock (cement board).

Do I use a thinset to put tape on? Do I use a thinset to cover tape after it is applied? Want to use it in a new planned shower.

Asked by: Marilyn
I would use Custom Building Products VersaBond 50 lb. Fortified Thin-Set Mortar either gray or white depending on color grout. Using ALL custom products they back their product no matter what as long as all the custom products are used. Ask a sales associate to explain that to you. Put the product on first to embed the tape and then once or twice over to cover the tape. I always put !00% silicone caulk in the joints before the thin-set to ensure water penetration in case it gets through the grout and then the seam behind it. Have not had a problem yet. Best of luck to you.

Customer Reviews

Alkali-Resistant 2 in. x 150 ft. Self-Adhesive Mesh Cement Board Tape FDW8691-U is rated 4.6 out of 5 by 62.
Rated 1 out of 5 by from Low Adhesion I did some research on using the “alkali resistant” mesh tape. Reccomendations were to use the tape as it may last longer than regular fiberglass tape on tiling projects. One person mentioned that the tape wouldn’t stick to the vertical surface it was applied to. I decided to try it anyway and had the same issues with not sticking to the surface for any time longer than about 5 minutes. If you have your mastic or mortar ready, apply the tape and immediately apply them, otherwise, the tape will fall off any vertical surface rather quickly. I cannot reccomend this product; however, it is the only option I have at my HD store.

Rated 5 out of 5 by from Amazingly easy to work with - does inside and outside corners with ease. Two thumbs up. Just remodeled our bathroom and made a shower niche with backer board. I used this self adhesive cement board tape to reinforce the inside and outside corners of the niche along with the seams of the backer board. Amazed at how easy it is to work with, sticks and stays put and even stayed put on inside and outside corners. We cut it with scissors and applied the thinset as soon as we'd finished taping the joints. There was no sign of the tape losing adhesion although the instructions recommend that you don't leave an unsealed taped joint too long before applying the thinset otherwise the adhesive bond can break down. Once the thinset was set, we applied a waterproof membrane to the shower niche and the whole job was very easy.

Rated 5 out of 5 by from Easy to use and self adhesive feature works well! Tape was used for a DIY pool bathroom remodel, which was converted into a wet room, with shower, toilet and sink. All the walls floor and ceiling are Durock with Redgard liquid membrane sealer, and then tiled. After the cement board installation, I wiped down all cement board seams with fresh water to remove all the dust and debris prior to taping. I also sharpened a 4" putty knife to facilitate tape cutting. Application of the tape was made easy and fast by unrolling the tape directly onto the seam, then striking the tape down by running the putty knife over the tape to flatten and press it down, assuring good contact of the adhesive with the cement board. At the end of the seam just tip the knife up and use the sharpened edge to cut the tape by pulling the roll against the sharpened edge. I found the adhesive to be more than adequate after taking these two simple measures. No measuring, and no loose tape fibers, tangles or stuck together tape. My only complaint is that it should be available in 300' rolls. My 5'X8' room used one complete 150' roll plus about 15 ' from another roll, hence the lower value rating
