Anybody fitted glass tiles from Topps?

[Tilerbhoy]

Got a job thru Topps to rip off glass metros which had been tiled but water marks were coming thru,the tiles were from British ceramic tiles.the firm have accepted the backing was not the best so have now changed it and accepted the bill.
i ripped off old tiles and adhesive,primed plaster(bal) retiled using mosaic fix(recommended by manufacturers)all back skimmed and grouted following day.
iv went back to do another job for them and noticed marks coming thru tiles again,which were not there when I grouted it.
anyone had the same problem,personally I think the backing on them is not up to scratch.

Some glass mosaics must not be fixed with a water mixed adhesive , are they painted backs or colour bonded.. ?

If in doubt contact tile manufacturer ..

Colour bonded but looks like a thin layer of paint.
topps supplied the material as advised from manufacturers
