lost marbles! · 08-03-2008

Hi guys just needing a little reasurrance about fixing backerboard to floor

After securing existing floor i have screeded over with multiflex addy using 6mm notched trowel then layed backerboards and left to dry for a while then screwed them down at 200 centres ( is this correct ) as someone has said they should have been screwed down whilst still wet ? but surely doing this would just squeeze the adhesive out any advice welcome ...

p.s been on hardi website but it doesnt specify
pps anybody found some marbles

Its just stuck down with the adhesive. No More Ply is Poly adhesive and screws.
