Evening all, so I am going to fix these tiles to cement board (going to go with hardibacker) which is capable of supporting the weight. My question is, must the Cement board be fixed to the actual blockwork (thermalite) or will we get away with grip filling the board to the plaster, which is skimmed over the blocks and then fixing with masonry screws, followed by taping and jointing. Don't quite fancy hacking off plaster if it's unnecessary....thanks!
