Hi The screed is from Lafarge, and its GYVLON gypsum based screed. We want to lay marble tiles ontop, with wet UFH. I think we are now going with the ditra membrane, can you advise best adhesives to use for membrane and anythingelse we should be aware of please. Thank you so much for your help.

Yes we are worried!! We are now looking for other quotes, anyone want to quote we are in Hodnet Shropshire. Please contact me on here and I will get in touch Its 64m2 of Botticino Marble Opus pattern.

Its from Lafarge and called GYVLON if that helps.

as stated I would recommend NICOBOND GYPFIX adhesive to lay the ditra, this is a gypsum based adhesive and avoids the possibility of any reaction with the gypsum based screed.

Follow my previous post and job will be right.

any tiler worth employing to do this job for you would know all this anyhow and if they don't then tell them to jog on.

Spanish seems to have pretty much nailed it. If there were joints in the screed i would say you might get away without the ditra if using gypsum addy but as it has cracked it is unsound and therefore needs something to help stabilise the tile face.
