Question: I am doing a new shower tile install in my bathroom. I have the durock slightly above the flange of the tub, but what do you use to cover the gap between the tub flange and durock? It's not a big gap, but in all videos ive seen there is something there, whether it is tape etc. I ask because where the tub flange ends there is still a little bit of tub left over that starts curving down the wall and there is a small hole (about the size of a quarter) where the 2 pieces of durock meet. Is there a special tape I should use, then mud to cover these small gaps and small hole? I know my tile will eventually cover but I want to make sure I do this right.
