This guide will walk you through how to reattach bullnose tiles that have fallen off, letting you complete this home repair for little to no monetary spending instead of paying someone else potentially hundreds to do this for you. This guide requires the prerequisite knowledge of how to use attach a silicon sealant tube (a grout tube) to a caulk gun and how to operate a caulk gun as a caulk gun will be used in steps 20 and 21. To learn more about operating a caulk gun, visit this page.
To check you have all the tiles in the correct alignment, place the bullnose tiles along the edge that they broke off of to make sure they fit.
Remember, the standard size tiles (typically the longer ones) should be placed towards the center with the remaining tiles (typically the shorter ones) on the edge.
Prepare about three strips of painter's tape per complete tile or one per broken tile piece.
These tape strips will be used to hold the tiles in place while the glue dries, so make each one long enough to secure tightly over both sides of the tile.
While drying, the glue may foam and eventually become firm when dried. This is normal. This is how industrial grade glue gets to as much surface as possible for the best attachment.
The tape directly touching the glue will be harder to remove, so do not focus on removing those pieces right now. They will be removed later alongside dried excess glue.
Use your standard scraper to remove as much dried glue that found its way between your tiles. This space should be made as clear as possible for grout.
