We have wet underfloor heating and a screed down on our new kitchen floor. We bought crack matting after reading up to put down under or limestone tiles. Research said we needed to use full screed of flexible adhesive and then the crack matting, then adhesive and the tile. The tiler has then started doing it like this but then stopped for some reason. Meaning few rows of tiles have no adhesive under the matting at all and some has patchy screed, only discovered as few tiles were loose with just dabs of ahesive. The kitchen isabout 45 square meters andwe don’t know if we need toask him to take it up and relay at own cost? Or justtake up few rows that it’s missing from, and if that would weaken the soundones? Not all tiles loose but can see from few that arethat nothing under matting.We given him £1000 for materials and if need tocome up then wasted. Help!
