I'm doing a tile fix for my friend's pool in the NE. The y are 6" tall mosaic sheets. I have done a good amount of tiling, though not on pools. As you can see in the pic's, only the top piece has popped off in several places. There are more still attached that are bulging out from the top. There is little to no thinset on the backs of the ones that popped off (they came off "clean") , leading me to believe that moisture got behind them. I see no cracking of the beam either.
My hope is to just replace the top pieces that fell off. I'm having a hard time finding the same tile anywhere. Does anyone have any ideas? A slightly different shade of blue would be ok..pool#1a.jpgpool1b.jpgpool1c.jpg
