Am applying 2 coats of tanking slurry on to a 9" solid wall, followed by dot and dab insulated plasterboard.

Cant use foam as the walll is not level/flat in many places

I also want to make my wall vertically level hence dot dab.

Do I need to apply a primer onto the dried tanking slurry before dot and dab adhesive? I need to wait a mo th before boarding as I need new doors and windows.

Thanks

Think you need a tight scratch coat or you’ll get dabs showing through on the boards, as the tanking slurry will condensate

You will need a primer or PVA because The drywall adhesive will not adhere to the tanking properly. The dots can pop of the tanking when dried if the board is hit.
