Vinyl flooring over quarry tiles

Hello, The 2 surfaces can sweat, the best thing to do is put a thin screed( self levelling compound) on the tiles then put the vinyl down. This will smooth out your floor surface and prevent the quarry tiles embossing the vinyl.

yes but you have to prime and latex the floor

Yes it can cause problems. All depends on your water table of your kitchen compared to outside areas. Screeding won't make any different to moisture making vinyl bubble without a liquid DPM. I repair floors like this all the time when people gamble. There are vinyls which let your floor breathe like Altro expresslay but as you have already got your vinyl then one way of doing it to be safe from raising moisture is - Apply a coat of surface liquid DPM to the tiles like Ardex DPM 1c or stopgap F77 then prime and screed. That will stop any raising damp to your vinyl.

just do a dpm sandwich, apply dpm to tiles screed and re-apply dpm with roller again, fit flooring.
