Quartz tiles problem

[Shazzapat]

Hi - new house with underfloor heating layed on top of anhydrite screed. Quartz tiles bought from online retailer. Floor primed with p51 - ardex x77w adhesive used and ardex fl stormy mist grout used. After a few weeks tiles started to lift at ends now 4 months since laying most have lifted. We checked with retailer who are insisting they are suitable with Ufh and saying it must be something we have done. Identical house next door with Ufh but normal porcelain floor tiles and no problems. Does anyone have any ideas. Thanks

did you slowly introduce the heat on ufh or did you wack it straight up?

Look at some recent threads on quartz tile problems there is some great info that has been given recently on Quartz and its suitability for UFH.

Was the floor properly sanded and vacuumed before being primed? Quartz usually specifies a two part adhesive as well.

How thick are the tiles?

the chemical make up of quartz is predominantly resin...not great with UFH of any kind IMO....

I don't put the two together, quartz or UFH but not on the same job. Too much of a risk I reckon.

Was the online retailer from the north east by any chance.

Quartz tiles are often not suitable for use with underfloor heating
