Ceramic tiles crazing ? Baffled ? Advise please !!!

[Gez2312]

No , not dabs fully covered the back of the tile and adhesive not deeper than 20mm . Can't see any reason for the crazing , even if they were dabbed ? I'm fuming that the tile suppliers have admit fault first time with no real queries , but now will not even go and look ! Surely if it was faulty tiles first time it can happen again ? And to blame me to the customer is wrong especially when they can't explain why it's happened!

Manufacturer?

The adhesive shouldn't be any thicker than 6mm on walls.....because the adhesive is rapid set it can dry to quick cracking the glaze...try using a slow set adhesive.....or ring the adhesive company tech depot tell them your fixing method and see if they can shed some light. .

They are a BCT granite white , I have got pics but don't know how to load them .

 

[Gez2312]

According to manufacturers , adhesive can be up to 20mm thick , I've used loads to this adhesive before and never had a prob with it. I've put it on deeper before and not had problems. It's just strange how this has done it twice now ? I'm happy to go and re do it again but don't want to waste my time if it is a problem with the tiles ! Anyone know of anywhere I can send the tiles to have them tested ?

So are they Johnsons???????

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 !
