British ceramic tile , had to ring and ask supplier ! I've used Bct before and not had problems (apart from being bent and out of shape!)

I use a lot of BCT tiles , which one is it ?

 

[Gez2312]

It's 'white granite' 400x250 ish , they agreed to replace them within 3 days of complaint going in which makes me think they have a had a problem . I kept some of the removed tiles as I thought someone would want to see them but got told just to bin them !

20mm adhesive? Would've been cheaper and quicker to re-skim with plaster! What's the name of the tile manufacturer?

Primer/SBR to seal stick areas. I was told that Mapei (for instance) will not guarantee their adhesive if it is stuck over PVA.

They were British ceramic tile .

20mm adhesive was not everywhere ! A lot of it was tight back to the wall , but it bellied in the middle. Can't see how this would make the tiles craze though ? And co incidentally the tiles are crazed more away from the deeper adhesive , also when I said pva'd I did mean primed ! Just force of habit saying pva !
