How to Fix a Chipped Sink. So, you dropped a glass bottle in your bathroom sink and not only did it break and make a giant mess-it took an ugly chip out of the enamel in your sink.
Sorry to hear about the mess-but the good news is now that you've cleaned it all up, you don't have to live with that ugly chip mark in your sink-or even worse-need to replace your whole sink. Fixing a chipped enamel sink is pretty straightforward. Here's how to do it.
- Sink Chip Repair Kit (available at most home or hardware stores in a range of colors)
- Wet/dry sandpaper (600 grit)
- Small (tiny) brush or a wooden match.
Scrub and clean the chipped area thoroughly using detergent and a sponge. You want to be sure you get any soap residue off the sink surface.
Dry the sink, then let it air-dry completely.
Rub the damaged area with the 600-grit wet/dry sandpaper to remove any rust or stubborn dirt. You want to be sure to rough up the metal and the edges of the chip so the liquid patch will have a good "tooth" to grip onto.
Apply the repair epoxy in a thin layer using the tiny brush or wooden match. (Some repair kits include a tiny brush or you can usually find suitable little brushes in the paint department of home stores.)
Use a number of thin coats of patching material rather than one single thick layer. Allow the first layer to dry thoroughly (read the instructions on the package for timing) before lightly sanding the area and applying the next layer.
Once the repair is complete, allow it to dry for at least 24 hours before you use the sink, and don't scrub the repaired area for at least a week.
