Soo... I am tiling around my new acrylic tub. It has a flange at the top. The manufacturer's instructions show the tub being held by the head of nails, but the nails don't actually go through the tub. The 1/2" densshield butts up to the stem of the nails and stops short of the head so there is about 1/4" between the board and the tub lip. I plan on filling this gap with caulking (I think that is correct).
The real problem...the densshield sticks farther out from the wall than the nail heads. I understand that I lay tile on the densshield into the tub so it is caulked to the first ledge on the tub (filling a small vertical gap). This means that the tiles will have a void behind them (about 3/16" deep). I am using 8x10 tiles.
How do I fill the gap behind the tiles so they are solid? (I will try to post a pic as well) ...or have I screwed something up here?
