dissolving backing - glass metro tiles - Tile Advice

[cazzapop]

Hi,
Looking for some ideas about what could have caused our lovely glass tiles to look like they are either wet behind them or the backing coating is dissolving away.
At first we thought they were still drying out but as the weeks have progressed there are more and more 'patches' where it looks as if they are not adhered properly.
Could this be due to an apllication/ adhesive problem? Should we strip them and start again? There were no special instructions with the tiles. Standard glass metro tiles from topps tiles. I am assured glass adhesive was used by our tiler.
I will try attach some pics to show our problem and would be grateful for any ideas as to the cause or if we should wait (been 3 months since done) and see if dries out.
Thanking you all.

Looks like the backing has been affected by the cement.

Did your tiler use "slow set"?

Not a lot can be done, other than remove and replace.

Have they looked like this from day one ?.....

I've saw glass tiles & they have a vinyl backing on them. You can pick at it & peel it off but its part of the tile, it isn't meant to come off.
As CJ says there isn't a lot you can do with them other than replace them.
Do you know the exact adhesive that was used?

Have they been like that since day 1??
and exactly what adhesive was used??

Had some problem with some Benetton branded tiles quite a few years ago, soon after the backing was changed but the supplier did pay for me to replace....

I've fixed glass tiles in the past (not these) where it said on the box NOT to use a cement based adhesive as it reacts with the coating on the back of the tile. In these situations I use White Star.

Rookery is right, I had this happen on a contract some years ago. Saying that though whoever sold them to you should have made you more than aware of the correct adhesive.
