The tile and plaster on my pool and hot tub was redone 2008-2009.
As obvious from the pics you can see tile is falling off where the cement was not built out. Can the tile that has fallen off and tile that you see just hanging, be reused by an installer? If not, I was thinking of squeezing caulk or something else recommended from here behind the tile to keep the rest of the tile from falling. The damage is not visible from house side so its not on the do now list.
