Hi, i got in a pickle with an ensuite (recently posted) & am now on the remedials.
Jason the tiler was a fab help thanks - but i can't keep pestering him as a go fwd...
Nearly all told me that my orig ply was too thin on the floor so it all came up again.
I was told to use 6mm Hardi backer to the floor instead.
I have taken up the old ply and am back to the green chipboard. I will now bang in as many screws as possible to the joists to really get it firm (150 centres).
My Q are:
do i just screw the Hardie backer to these & through to the joists, or does it need any prep first ? (hopefully not more ply as i'm trying to keep the height down.)
What screws / centres?
Does it need adhesive?
What if there are any small gaps do i "pack" it?
The when it's down, do i need a two part adhesive or will a flexible do? (tiles are 330 sq. ceramics)
I had a Unibond but have skipped that, so am keen to get it right.
I still have the Mapei flexi coloured grout (it cracked before but due to the thin ply & floor flex i guess) so will that still do?
It hasn't arrived yet and i may get a set of instructions (but i strongly doubt it).
Cheers.
