The other day, 3 pool tiles (technically, parts of tiles) all came off the wall in different points. Two in one area, one in the other. There has been a crack in areas of the grout, and some weird calcium build up that I'm thinking is now a problem. Behind the "paper" sheet of the tile there appears to be a surface crack, which I'm guessing caused the tile to pop off.
I guess my question is: is this a crisis about to hit that I need to deal with? I've assumed that this is someone natural settling (pool is 8 years old), but I'm concerned that it is a more major concern.
If not, is there an easy way to just backbutter the tiles and repair them? I'm not in a financial position to retile the pool. I think the rule of thumb is every 10 years or so, so I'd like to stall a bit.
Thanks in advanced.
