I have a shower with 1"x1" tiles in the floor. Whoever put it down did a lousy job and apparently didn't seal the grout. It's breaking up...tiles pop off easily. Not a big deal to replace that except for one thing....they used the Schluter-Keri shower system. The system is great if you're starting from scratch. but since I have 16x16 tiles on the walls that I'm not going to remove, I can't go up the walls with the Kerdi membrane. Here's what I'm thinking. Please poke holes in my logic.
I'll pull up the tile and cut out the old Kerdi..leaving about 2 inches around the perimeter of the floor. I'll pull off the old thinset from that two inch border (it pulls off with the thin layer of felt on the Keri...but not easily). Then I'll cut a new piece of Kerdi to fit the floor, apply thinset, and lay down the new Kerdi.. tucking the edges underneath the 2" border. I'll seal the edges that overlap with Kerdi Fix or some other high quality silicone sealant. Then I'll lay down my thinset and tile, grout.
Will it work? Thanks!
