I am fitting a new kitchen, and intend laying ceramic floor tiles.
When I ripped up the carpet, I found floorboards in poor condition which had been 'levelled' by covering with levelling compound which had since cracked. The boards had been laid directly onto the concrete base, but the seal (bitumen I think) had come away with the wood. The concrete base appears dry and sound.
I resealed the concrete with Bitumen paint and poured self-levelling compound onto this. I then laid tongue and groove water resistant 18mm chipboard which appears to be flat and stable. I left plenty of room for expansion - job done....except for a couple of mm movement around one doorway and one edge; enough to be noticable.
So should I try to eliminate this movement? I would prefer to leave the boards in situ as they are a *** to lift, in which case I suppose my 50mm screws and rawlpugs are now out of the question? I have BAL Flexible Floor Adhesive ready and waiting for my tiles, so perhaps this will be enough.
Any advice would be appreciated.
