I don't know until tomorrow, got to look at a floor that has failed twice and laid by the same tiler, the first time after about a year the next time after 3 months.
The guy doesn't want him back, surprise surprise, will post more tomorrow.
Been busy today. Stripped out a room of its old slate tiles, adhesive, Marley thermoplastic tiles, bitumen adhesive, old levelling compound and spray glue with underlay still attached. I then slurry coated it ready for levelling tomorrow. Oh and I grouted my shop doorway from the weekend tonight too.
