    Hi,
    Just finished screeding the floor over wet underfloor heating and want to lay ceramic tiles on top,is there a suitable tile adhesive/grout that is used in preference to normal adhesive/grout for underfloor heating as the temp change and expansion rate is much greater.

    you need to ask on the 'other trades' forum, that's where all the tilers hang out!

    I'm looking at the same job myself. Although I haven't source the adhesive, I'm advised that it needs to be a flexible type, that can as you say cope with thermal expansion and contraction.
     
  4. Barnsley is spot on, your products need container polymers that take up the thermal expansion of the heating.

    So flexible adhesive and flexible grout.
