fixing 1/2 inch hardibacker board to celcon block walls.
i need to fix hardibacker boards directly to celcon building blocks.i cant stud it out as space is limited in the shower.i was planning to rawplug it to the wall and use stainlesss steel screws.however the wall is slightly out about 1/4 inch overall.i could pack it out ,but are there any methods.

Is there any reason not to use dot and dab plasterboard then tank if it's in the shower..
The celcon blocks are quite soft if memory serves me right.

also forgot to ask how many coats do i require?.
Re: fixing 1/2 inch hardibacker board to celcon block walls.
Should only need 1 but thin it so it soaks in about 3-1...those blocks are quite absorbant..when it's dry splash a little bit of water on the wall if it soaks in do another coat, if the water lays on the wall that should fine.
