Tiling on underfloor heating - TilersForums.com

[Neilly]

hi, I'm looking for advice on laying porcelain floor tiles onto a sand/cement screed with underfloor heating throughout. I've been told to use some kind of matt or mesh? Is this necessary or can the tiles not just be stuck with rapid set and the sand/cement screed have a primer applied like sbr? The screed is totally dry, been down for months.
Thanks.
