Hi, im in the process of doing out or bathroom, we have 2 stud walls and 2 masonry walls, i will be using moisture resistant plasterboard and hardybacker in the shower area.
I have read up about the hardiebacker and they say not to dot and dab it, but to use mechanical fixings and gap filling adhesive. Now i need to pack out the wall by about 20mm to clear pipes and a gap filling adhesive wouldnt get this so i was thinking of batoning part of the wall where the hardiebacker will be then screwing to that (but will only get 20mm of solid fixing), or dot and dab with mechanical fixings to baton or wall (even though they recommend not dot and dabbing)
What would my best options be do you think, also if mechanical fixing, how do you go about doing that and what fixings are best (they say stainless steel) i think id need around 70mm fixings to reach through and into the plugs.
Do i dot and dab wall then let it go off then fix through when set (if so then how do you get wall plugs in) or do i fix plugs first and drive in whilst dot and dab is wet?
Sorry if this sounds confusing i just want to do it right the first time and not have to worry.
Thanks, brad
