I have a customer that would like to use 1"x1" sheeted square mosaic glass tile (1'x1' sheets) for the whole interior of the pool. It seems like a real PIA since we normally only tile the waterline and spillways. It looks to have an existing diamond brite surface thats in good condition. Any advice on setting materials would be appreciated. If anyone has an idea on the going rate for labor it would also be appreciated. I told them $10/SF for install (approx 2000SF) and they thought I was crazy. I would rather not touch this, but I don't want them to bring in someone else.
