I bought this for shower walls. Short version: Backer Board + 3.5 packs of Adhesive Tile Mat / Membrane (this stuff) + “Sticky-Back” VINYL tile + Vinyl Tile Grout and Caulk + Trewax in Satin Finish = perfection The first time I used this stuff I bought it trying to avoid using backer board. I thought it would save me some time. I just leveled out the green board until I thought it looked level, which took more time than if I had just used backer board, which would have also looked better. I made it work but wish I had just used the backer board. Second bathroom I bought backer board and vinyl tile glue. Glue didn’t stick and lost half the tiles overnight. Went back to Lowe’s for more of this stuff. Worth it. I complained before about this stuff being difficult to work with, but it seems to be very forgiving, and sticks really well even after my many misplaced tiles that had to be corrected. I used this under (not-so-sticky) “stickyback” vinyl tile and it still held, which I was concerned about. I had to pull up the stickyback tile after it didn’t adhere correctly the first time without this stuff and even after pulling the tiles off and reusing them on this, it held great. It took 3.5 of these to do one tub shower surround, so it isn’t cheap, but worth the time and effort if you ask me. You can also patchwork it if you’re running low and have a long skinny strip left. I’m keeping the scraps around as double sided tape for any other household projects I have! Yes, I’m using vinyl tile on a shower wall. Yes, I know it’s not recommended, but I wanted to prove it could be done, so here goes nothing. I’m using linoleum wax on it for an extra line of defense. So far so good! In the pics I haven’t finished with trim yet, but you can see how nice the walls look. I will be using vinyl trim. I’ve been using one of the showers for a month now with no problems. Hope this helps someone.
