Tiles cracking, is it the adhesive or something else?

[White Room]

What was the substrate ???

Think the answer is in the matting,,,,,

What makes you say that , what your thoughts Ali?

had a job a few yrs ago washed the grout off using warm water and the grout started to craze.
the job was beginning of the year and the tiles were stored in our lock up onsite think the out side temp was minus 10 the job was a car auction build at black bush were that plane came down last month
the crazing was caused by not acclimatizing the tiles befor fixing and grouting

So this would go hand in hand with the heat from rapid set as it chemically hydrates .. The thicker the bed the more heat is potential..

could be a poor quality batch of tiles and the manufacturer passing the buck
ITS THE TILERS FAULT

So could just be really thin glaze and rubbish biscuit and perhaps temperature shock if it's only the shower area.

good point dave
chemical hydration and poor quality glaze equals crazing
the tiles wernt made by j********* were they
seen there glaze craze when cutting

To be fair I'm not 100%. But let's call it a gut feeling and 99/100 times its right.

No way it's the use of rapid adhesive. Not months after the install, and not to the extent that's in those images.

The corners are poor. Metros unscribed in the corners leaves those diamonds. If these are filled with grout rather than Silicon we effectively, through tile type have Wells or pockets.

I think there's water ingress in the corner and it's making a poorly fitted tanking membrane swell. Collection of water or a swelling in the substrate behind.

Along those lines anyway, but for cracks to run through the grout joints like That it's substrate for sure.

Porous biscuit like a lot of white biscuit tiles are , will suck the moisture from rapid set thus creating a faster set time ... One of the reasons tiles used to be soaked when fixing in sand/cement and slurry bond, stops the biscuit drawing excess moisture from bedding mortar.

A problem not associated with a slow setting adhesive.

Pictures 3,4 & 5 look at the grout in the corner. Clear movement cracks.
It isn't crazing of the glaze. The tiles have broken right through.
It's movement for sure, and I think its certainly starting through ingress in the corner.
