How to Fix a Ceramic Sink

Quck answer

To repair a ceramic sink, follow these steps:

1. Clean the damaged area: Use a mild detergent and water to clean the sink thoroughly. Remove any dirt or debris.

2. Assess the damage: Determine the extent of the damage. If it’s a small chip or crack, it can be repaired. If it’s a larger or deeper damage, it may require professional help.

3. Fill the chip or crack: Use epoxy or ceramic filler to fill the damaged area. Follow the manufacturer’s instructions for the specific product you’re using.

4. Smooth the surface: Once the filler has dried, use sandpaper to smooth the repaired area. Start with a coarse grit sandpaper and gradually move to finer grits.

5. Paint or glaze: If needed, apply a matching paint or glaze to the repaired area to blend it with the rest of the sink.

6. Allow it to cure: Let the repaired area cure for the recommended time mentioned on the product packaging before using the sink again.

By following these steps, you can repair a ceramic sink and restore its functionality and appearance.


Just dropping a dish into your ceramic kitchen sink can create an unpleasant dent. Luckily, most hardware stores sell sink repair kits that allow you to fix the damage instead of replacing the entire sink. The repair process is fairly simple, but it requires delicate work, patience, and a steady hand. Additionally, the repair needs at least 24 hours to set, so plan your project accordingly.

If you have a small scratch or dent, you may be able to fix it by purchasing porcelain touch-up paint. This paint comes in various colors, allowing you to match the finish of your sink. Some paint manufacturers even collaborate with sink manufacturers to precisely match their colors, so try to find out the brand and official color of your sink if possible.

If the chip in your sink is deep, you will need to repair it before applying the touch-up paint. Look for a two-part epoxy ceramic or porcelain repair kit. Epoxy is applied to the sink while it is soft, making it easy to work with. It then hardens, ensuring a long-lasting repair.

Prepare the Surface

Before fixing the sink, thoroughly clean the chip and the surrounding area. The epoxy will adhere better to a clean surface. Any general-purpose household cleaner will suffice for this task. Once cleaned, dry the sink.

After cleaning the chip, use 400- or 600-grit sandpaper to roughen up the surface. Creating texture on the surface allows the epoxy to grip it more effectively. However, be cautious when sanding to avoid scratching the ceramic next to the chip.

Repairing the Cracked Sink

Now that the prep work is done, you can proceed to repair the sink. Follow the manufacturer’s instructions to mix the epoxy in your repair kit. Once mixed, carefully apply it to the chip in your sink. Ensure that the epoxy goes into the chip without spreading onto the surrounding area. You may need to use a toothpick or a tiny brush to apply it accurately.

If the chip is deep, you might need to apply the epoxy in thin layers rather than all at once. In that case, allow each coat of epoxy to dry for 24 hours before applying the next one.

After completing the repair, run a credit card or a straight edge across the chip to ensure that the epoxy is level with the top of the chip. Take a moment to assess your work. If you are not satisfied, simply wipe away the wet epoxy and start over. Keep in mind that epoxy does not expand or contract as it dries, so the final result will look exactly as it does now.

Painting the Repair

Allow the epoxy on your sink to dry for 24 hours. If the dried epoxy matches the color of your sink, your repair is complete. If not, use porcelain touch-up paint to cover the spot and blend it in with the rest of the sink’s finish.

After completing the repair and applying paint, True Value suggests allowing the sink to dry and fully set for a period of 24 hours. Once this time has passed, you may use the sink; however, it is advised to refrain from scrubbing the repaired area for a minimum of seven days.
