Hi, Does anybody know what subfloor this? Have just taken up old quarry tiles to allow to fit new porcelain tiles. We know that there may be a problem with dpm and damp sitting under new floor covering but rooms well ventilated so going to seal the floor, self level and then fit new porcelain tiles.
Any help on what material this subfloor is would be great and any advice on the job were doing!
Cheers
