Help: What to use to seal one tile back onto wall?
My bathroom wall is tile from floor to halfway up, and then old wallpaper. I decided to take down one portion of the wallpaper to investigate what was under it. One of the small tiles at the top of the half-tile portion was loose, and the wallpaper must have been holding it up because when I started lifting up the wallpaper I had to catch the tile before it fell to the floor. :-)
There's some brown dried up crackly looking adhesive left in the place where the tile was. It looks as if the tile came out previously and reattached by the previous owner (for one thing, the tile itself has a few cracks and it looks like it broke at one point in its life and he glued the tile together and then adhered it to the wall).
How should I best reattach this tile into its place? Thinset? Krazy Glue? ;-)
It only has to last about a year or two until we really redo this bathroom.
Thanks in advance!
