Hardiebacker or no more ply? - TilersForums.com

[john56897452]

Hi,

Looking at tiling the floor of my bathroom. No UFH just plain tiling. Whats the preferred base?

Fixing onto solid floorboards (no squeak or bounce). Screwed down NMP or hardiebacker, or any other product suggestions?

Thank you for reading

John.

Either of those or a 6mm insulation board such as marmox, wedi, delta

I normally go for no more ply as you can use mega strength glue and screws

Got told the other day than 6mm xps style board isn't suitable for timber overlay, 10mm minimum. Apparently

Interesting. Who told you that? Pretty certain from memory that they all state it's a recommended method with 6mm. I have certainly never had any issues.

Manufacturers say that 6mm insulated board isn't suitable for floorboards and suggest to use thicker board but not for ply or chipboard etc.

I can honestly say that I have never seen that written anywhere. I'm not saying it's not true, just not seen it!

They usually drop that info into technical support or information or some sections where they explain how to use products.

But you're right its not easy to find.

Well I found it at last, hidden in the depths of a Marmox PDF document!

Great info lads, this kind of thing is exactly what this forum is all about
