I have pulled up 99% of the cement board and tile from my bathroom, and am fighting with the edge that is up against the tub. Some of the board broke off a half inch under the tub, some broke off a half inch out from where the side of the tub meets the floor.
How much do I have to clear out under the tub to slide in new cement board, or am I just wasting time and should run a new straight line with the board and back fill with grout or mortar and some water proofing on top?
Thanks for any advice.
