Hi guys just after a bit of info if anyone would be so kind.

What i have done is used "Tilemaster Levelflex" to level the concrete floor.

As im going to use UFH i was going to line the floor using 6mm Marmox boards then tile ontop of the Marmox.

What im unsure about is do i need to use flexi adhesive on both the Marmox to the floor AND tiles to the Marmox or can i use non flexible adhesive.

Sorry a bit long winded but had to get it all across.

Many thanks

Hi and

Yes, you'll need to use flexi adhesive for both the insulation boards AND the tiles themselves

Cheers fella thats what i thought as i origionally bought none flex.

Looks like ill be back to the shop then.

Thanks again.

Dont suppose you could recommend a decent one to use.

Mapei Keraflex Maxi would be my choice - available from Tile Giant stores. Its a long pot life, slow setting one though so you'll not be able to walk on the floor for about 24 hours.

Make sure you use a flexi grout too - Mapei Ultracolour plus or something similar.
