I have a 15x60 infinity edge pool with a pool cover for about 7 years now. I live in central coastal california where the winters go into 30s. On the other side of the infinity edge where the water falls over [the trough side] is tiled with small glass tile. We have a problem with many many small tiles coming off of the back where the water comes off of the back of the infinity edge every year and seems to get worse. Because the tiles are small, there is less grout on each tile, and more irregular surface which also causes more scale build up [we have very hard water]. My question is this, I would like to get rid of the tile on the back. I know we could do a large format tile, but is it possible to do some kind of epoxy plaster or some other option other than tile that can be used off of the back of the infinity edge that can be exposed?
