hi chaps just picked up a large job from a builder who has put down 6mm 'STS no more ply' boards over omnie UFH which is upstairs so on ply floor , he seems to think 3mm self level would be ok on the boards to then fit Amtico spacia. has anyone had any experience is this before? do you think the self level will be sufficient? slight concern as its all open plan lounge/kitchen with lots natural light. TIA
thanks guys for your help, im going try spaceys way (you should have a degree in flooring) as they have put the staircase in with 8mm tolerance so only got 5mm to play with.
