Wet Ufh - Tiling Onto Screed - Tile Advice

[bassmonster]

Hi all,

I'd appreciate any help.

I'll be installing wet underfloor heating in a new extension. I would like to know if i can tile straight onto the screed with flexible adhesive?

Thank you.

What tiles are you fixing, what type of screed is it & how big is the area?

It'll be porcelain tiles.
I'm not too sure what type of screed as it's not been laid yet. The floor area is approximately 17sqm.

is there a certain type of screen that needs to go onto wet UFH?

the floor will be concrete with joists on top, then celotex boards and pipes clipped onto them.

I think the screed has to be 70mm.
