i tiled a bathroom floor last october which was a new build, floor was 3m with a border in the middle ,so 1.5m was tiled at a tme onto 18mm ply onto joists with plenty of nogins , primed plywood and left to dry for the day , tiled floor using 600mm by 300mm porcalain tile fixed with ultra single part flexible white,grouted in with mapie ultra , to my amazement the tiles have now all lifted ,the adhesive has stuck to the ply with only an impression of the adhesive on the back of the tile, the grout does not seem to have adherered to the tile well, 1. has the adhesive not stuck to tile 2.or the tile to the ahesive 3. has the floor moved and tacken the adhesive away from the tile , has anyone had a problem like this before
