I am putting in a new bathroom floor and have started chipping out the old ceramic tiles. They were laid on a 2" cement bed. I am using my air chisel to knock out the tiles. I am hoping to lay new tile on top of the old cement bed, but have some concerns regarding the integrity of the bed after all of the old tile demo.
The bed seems sturdy, but I wonder if anyone out there has gone through this.
Use the old bed, or tear it all out and use cement board?
