If it makes any difference I have wet UFH under the floor deck.  My favourite at the moment is 18mm OSB then 6mm ply, but am concerned at how to glue so it's solid.

But the tanking membrane you linked to ear;ier, this one http://www.impeyshowers.com/waterguard says:

 

Only 1mm thick with superior De-coupling properties of 10mm
Economical and safe - no need to buy a additional decoupler

 

If I have to fit something over the chipboard, then the aquapanel sounds a lot better, nice and solid. I just can't get it out of my head that 6mm ply is flimsy, and would only "work" in my mind if you clued it down with a 100% bed of adhesive like spreading tile adhesive over the floor to stick it 100% with no voids?

 

Have I just been lucky with my old house, 17 years of tiles glued direct to chipboard with no issues?

 

18mm OSB and 6mm ply sounds the easiest but I can't get over my mind saying it has to be 100% glued or it will flex?

Sorry, the problem with me grafting whilst posting ?  

The membrane can be used to decouple, I forgot about that. I don't routinely use it as most bathrooms I do are way over the 5m2 standard kit. 

If your at 5m2 or less you can go straight onto the membrane. Sorry for the confusion ?

About 6 square metres per room, less if you exclude what's under the bath and under  a boxed in cupboard.

 

So are we now saying that tanking kit direct on V5?

 

My head is hurting keeping up with the conflicting ideas.

Ok.  As Chris Tarrant would say...."final answer" ?......

22mm deck, sponged clean with a damp sponge. 

Primer as per Impey's instructions. 

Impey water guard membrane and strip / corners / butyl sealant as required.  

A good quality flexible tile adhesive. 

Tiles. 

Pub.

Ive used that kit a good few times tbh, with great results. Only thing is after a quick scan it doesn't say that the membrane decouples. 

@ProDave, maybe ring their tech support as the price drop is significant ;)

They also do a 7.5sqm kit of that aquaseal, which works out cheaper per sqm

Mapei stuff is good gear ;). Used loads, especially their grouts and sealants :)

Yes, I used that size kit with a Roman tray and it had good coverage tbh.
