right, i have a problem - i have paramount walls, and i need to fix up them up ready for tiling.
do i a: remove the offending boards, and put new ones up
OR b: dab+dot new ones on top of the old ones?
If its a: will a skim of drywall adhesive on the back of the board be enough to grab the paramount card ?? Or will it be a job for MR unibond pva ?
if its B - whats the minimum depth i can put the new board at. By that i mean : after i put the board onto the wall with drywall adhesive, how far can i push it to the old board ?? 5mm ?? 10mm ???? Needs to be fairly flat for tiling of course.
