I have tiled 600 m porcelin tiles to a bathroom floor on 12mm plyboard which is sound then 100msq screwed.
I have primed floor with mapei prima g
layed the tiles with keriquick flexi layed dry first so the gear didnt go off on me .
left it a day grouted it with jamsine ultra colour
came back over the weekend and there is hairline cracks in the grout between the tiles :yikes: i have never had this before!
i put a verygood thickness of adhesive down i looked at one of the last tiles at the door jam and i noticed a hairline crack between the adhesive and tile itself :yikes:.
and when pressing on it i seen slight movement so i lifted it off to my surprise the wasnt much adhesive on the tile but the adhesive on the wood has even got the code of the back of the tile imprinted on to it .
So theres more than enough adhesive on the ply which is solid and has adhered well to the ply .
Dont get me wrong this was the only tile with a bit movement even at that it was very slight.
But im hopeing the hairline in the grout is down to shrinkage.
I have check all tiles to hear if they are any hollows but there all solid .
surely the tiles are porous enough to stick to adhesive in which btw wasnt to runny or to dry.
All advise will be appreciated
cheers!

if the tiles have any dust on the back that might have stoped them sticking with the adhesive
