Tiling onto Ply, can it be a success?

[Wayne Brown]

6mm for me with those mats for full coverage.

Am I reading this right, you have put ply over an anhydrite screed with ufh?

I thought that bud why fit ply over the screed ? It is such a poor conductor of heat and is a laminated product any moisture in there will result in failure of the floor there are far better options. Kop

The Screed is between the joists and not load bearing. It is supported by the insulation underneath. The 18mm ply is the structural load bearing floor and although it does insulate, it doesn't make the system ineffective and requires the flow rate to be slightly higher than a screed floor.

After living with it for a year I can say I'm impressed with the efficiency and performance and I must say I was sceptical before installing it.

Somewhere along the line it sound like you are going to have an edge of your 18mm plywood that won't be mechanical fixed down to the joists(in between the joists) Ditra will only accommodate lateral movement, not vertical movement.

Magix might be nicer than Setaflex?

I've gone with Mapei Keraflex Maxi S1.

Thanks for the advice.

Would Ultimate s2 be any good for setting ceramic wall tiles?

Just thinking I could use it up elsewhere.

Don't mind me while I bump up some older but good threads. If you can contribute to the thread, go ahead. But if it's nothing for you then don't reply and it'll soon drop off the What's New page etc.
