Removing tile from a dated bathroom. Behind the tile it looks like 2 "layers" of concrete. Any suggestions on what to use and how to fill the void. I obviously need to get it all flush for the new tile. Thanks so much for all your help!
That old cement scratch coat is to far gone to save.
You need to remove the mesh and cement back to the studs and furr the wall out so you can install modern Durrock or other cement board.---Consider waterproofing the surface of the new board with a paint on membrane like Redguard or Hydroban.
