Wet Room with Anydryte Screed

[Thehulk]

I have been building a house and my floor has wet UFH with Anydryte screed. With recomendations off the forum i will be laying Ditra matting with Anyfix and then marble tiles with a weber cement based adhesive.

So the problem is the wetroom downstairs, the screed is anydryte but i shuttered off the section where tray was going when the screed was being poured, and then used cement to finish the tray off.

I now want to tile the room with a mixture of marble mosaics in the shower area with the rest of the room in a larger marble tile. I understand the Ditra is not suitable for wet rooms? What would be the best way to tackle the tiling in this room? your help would be appreciated.

ditch the ditra and use a thinner decoupling membrane as it will let the ufh work more efficiently

Like - not! Pressed the wrong button.
What other decoupling is thinner than Ditra?
There are other membranes but they don't decouple and for Marble with UFH I'd recommend Ditra!

I have seen this product used as well and have nothing against it but I would think ditra is more suitable for this particular application as I believe the sandimat to be vapour permeable. As there is likely to be a lot of water about this would be counterproductive and could lead yo a de lamination of the tiles. The critical point in this application is that water from the shower area is divorced from the rest of the screed.

Okay thanks for the responses. So follow the same format as with the rest of the house and use the ditra matting. What about tanking with the matting, obviously tank all the walls, lay the matting, any other advice? Tape after the matting is down?

I suppose i need to be a little carefull as the floor is Anydryte but the aqua grade tray i put in has been filled with cement.
