Tiles coming away from wall?

[flobadob]

A couple of the tiles in our shower are coming away from the wall. They are both still connected at the sides to the surrounding tiles but have come away at the top and bottom. Is there anything I could put in behind them to stick the tiles back onto the wall?

This might be useful though it assumes you will be replscing a damaged tile....

I just assumed there would be something like silicone or something that I could squeeze into the gap behind so that they would stick back onto the wall.

Unfortunately there isn't a lot you can do into a 2mm? grout gap,you could possibly clear any grout remaining on the top and bottom only,then inject with a very fine nozzle some water proof silicon seal put as much as you can into the top,until it come out the side of the nozzle then when dry trim surplus off and leave as grout,try to leave the bottom so that the plaster that has been acting like a sponge ,will dry out hopefully, then do the bottom as the top, a hair drier may aid this process.HTH Tez

I would want to know why it had loosened.....is there water getting in behind the tiles?

tiles often come away from walls because the wall has shrunk imperceptibly or the grout has expanded owing to recrysallisation caused by frequent wetting over many years. This results in insufficient room for the tiles so they have no option but to find room away from the wall. You will have to remove the loose tiles and refix them.

Not sure why. To be honest its probably been like this for a year and hasn't really gotten any worse, so I just thought I'd quick fix it if possible. Someone has told me something called gripfill or something like that will do the job.

Flob, it's not a major job to do it properly and it's a case of a stitch in time saves nine, so take them off, stick them back on with tile adhesive and then grout.

I'd use a combined grout and adhesive just forced into any gaps with a filling knife. Any damp behind the tile will be able to eventually dry out through the grout. Silicon might seal in any damp behind the tiles.
