Plywood or Hardiebacker or NoMorePly - TilersForums.com

[Colo]

Hello,
I would be very grateful for some help.

I have been left to finish a job my fittter started. He was going to overboard my existing OSB floor with 12mm ply and lay my 10mm porcelain tiles over . However, I have been left with the job and after doing some research on your forum I see that ply is not the best substrate.

I have looked at Hardiebacker and NoMorePly but I am unfamiliar with these products. I rang the manufacturer who states that 6mm boards are as strong as 18mm ply and to lay them instead of the ply. Is this product really better than ply.

Do any of you lads use this type of board and is it successful. Also which is best Hardiebacker or MoMorePLy.

I have tested the floor with a lazer level and there is no deflection.

I would be extremely grateful for any help as we are desperate without a bathroom.

If your fitter was going to use ply and tile straight onto it sounds like your better of doing it yourself anyway... 6mm Hardbacker fixed with tile adhesive and 25mm screws, stagger and tape the joints and your good to go

Thank you for your help and much needed advice. Like you said it could be a blessing in disguise.

What make of tiles are going down? If British ceramic then run away!

Yes I know its your house but still..run away!

Tape and fill the edges of the boards with strong grey Fibretape and leave a 3mm gap, don't use plasterboard tape.

I personally double tape aswell.

What's the 3mm gaps for bob?

I think Hardie recommend a 3mm perimeter gap

Ah perimeter gap, thought he meant between the boards..

Cheers for advice lads.

The tiles are not BCT (thankfully after what I read on here). They are good quality vitrified polished porcelain from an independent supplier.

What would you consider the best Hardi or NoMorePly. and are these boards really as strong as 18mm ply I find it amazing that somthing only 6mm thick can be as strong as 18mm ply.

I am grateful for all advice

Both companies make some outlandish statements about their products. But for me Hardiebacker edges it, if only for being softer and less liable to cracking at the edges when screwing into the floorboards.
