I'm tiling a shower with glass tiles. I'm using a Schleuter kit and due to a mismeasure I'd like to tile the end wall directly on the 2x4 because if I put concrete board on it the tiles will overlap the angle cut I made in the Schleuter curb. I would cover 2x4 with the Kerdi membrane first then tile it. My question is will the friggin tiles stick? As always thanks for your help.
