Hi, I have to tile an area abovr the bath which will be a shower enclosure.
Some of the plaster I've had to knock off and replace as it was blown.
I was just going to tank over this before tiling, however approx half the area of the wall is still old plaster, and whilst it's not hollow it is pretty old, so am concerned it may fail.
I therefore thought mechanically fixing backer board would be a better option, howbert the fixings would have to go through the plaster and into the brickwork behind.
Is this ok to do? If so, can you just use normal screws a d Rawl plugs? I see on the Hardie backer instructions it suggests using cement board fixings but can't figure out what these are. Cheers
