hi dexter not sure if this is the cause but i steer clear of standard flexis with water for this type of tile as whitebeam has said some are not too keen on water either
Thanks for all your advice I have Tech guy coming out from the Adhesive co, and he says it could be caused by heat. Apparently they had the same problem at Heathrow Airport. I am hoping this is the case. Thanks again Dexter
If that is the case who is liable when I the tiler has fitted them using all the right products and the product does what it has done and the customer is looking at me to replace every thing and the tile supplier seems to be washing there hands of it.
