I'm installing hardiebacker 12mm boards onto masonry wall and timber studwork around a bath.
Just have a few basic questions.
1) For the masonry walls I plan to fix the hardiebacker with Hardie foam adhesive and a few screws into rawl plugs set into the masonry.
Question - What is best way to fix the screws into the masonry wall?
Do you fix the hardiebacker with adhesive first?
then drill holes into the hardiebacker big enough to fit the rawl plugs and screws?
This would make the holes in the hardiebacker too big?
2) When I apply the jointing tape, do I use any tile adhesive to skim a thin layer between the board joints and over the jointing tape?
What product do you use for this? Mortar based or what?
3) for the rest of the walls and ceiling in the bathroom I was going to use british gypsum moisture board. Is this OK - or should I use hardibacker throughout?
