Before you do anything, I have a question. Have you called Florida Tile?
How much is installed? Don't install anymore until you contact FT. There is a disclaimer on the box (almost all manufacturers have it) that says once installed its yours. I suggest you call FT customer service first thing tomorrow morning and get started on a resolution. They have reps all over the county and I'm sure they will be interested in seeing what is going on.
No worries about this products being discontinued, at least not until Ceramictec has the state of Florida covered.
