How to Repair a Shower Tile With a Small Crack
Sometimes it is better to repair a shower tile rather than replace it. It is always recommended that you buy and store some extra tiles when remodeling your bathroom or shower for when you need to replace any damaged tiles. If you happen to be caught without any extra supplies and needing to repair a cracked tile, here are some guidelines to help you to do so.
TIP: This method is especially recommended for shower tiles which are not patterned, or for those which have just one shade which can be easily matched. Otherwise, you may have to totally replace the tile.
Step 1 - Clean the Damaged Area
First clean the damaged area with a mixture of oxygen bleach powder diluted in water. Apply this mixture to the grout as well. Doing so will remove any tile and dust particles and guarantee a better background for a neater final result.
Step 2 - Scrub the Grout
After leaving the application to work for a few minutes, scrub the grout lightly.
Step 3 - Apply Glue
Now at this point apply some glue on the area. Some clear 2-part epoxy glue is usually recommended. Keep applying glue until you level the corresponding tiles.
Step 4 - Paint
Once the glue has dried, use a fine paintbrush to paint over the crack. Use a cotton swab to dab the paint into the crack.
Step 5 - Coat
Once the paint dries, apply clear urethane to coat the area as this will greatly help to leave the paint in a good condition and prolong its durability. It will also avoid dirt from sticking to the paint. When everything has dried, wipe the surface with a damp cloth.
Step 6 - Use Paintable Caulk
You can also opt to fill the crack with paintable caulk and touch it up with acrylic paint.
Step 7 - Alternative Method
Alternatively, you can also use polyester resin. Use a putty knife to apply it to the crack in the tile. Fill the hole or crack as best you can. Once the material has hardened, trim the excess with a sharp object such as a razor blade. Once you removed it, make use of a fine grit sandpaper to brush against it and make it smoother. It is recommended that you wet the sandpaper slightly with water first.
You then need to mix colors, ideally from a range available in a porcelain touch up kit, in order to attain a color which best matches with the tiles’ color. This may take up some time until you manage to mix the right colors in the right amounts. Once you attain the best possible shade, simply paint over the patch where the crack was previously. Once it dries, scrub it lightly with the fine grit sandpaper to make it smoother.
