hi guys i've recently just tiled a bathroom floor.I have screwed all floorboards down so there is no movement then i 18 mm ply'd the floor screwing at 200 centres so the floor was totally solid no movement whatsoever.I layed 330mm x 330mm ceramic tiles onto the ply with a norcross rapid set flexi adhesive and have grouted with a charcoal grout (flexible)by stoneset.On looking at the grout very closely i can see hairline cracks on some of the grout lines(not all).How can this of happened or is it nothing to worry about? Could it of been that on the packet it says leave for 24 hours and maybe they have walked on it too soon?:incazzato:you cant notice them unless you actually get on the knees and look very closely but just thought id double check if its ok or it needs bringing up,not that i want to that is.All advice appreciated thanks.
