If you have a porcelain sink in your bathroom, you may see the porcelain surface wear over time. It will be very expensive to replace the entire sink unit. If you encounter mere cracks, chips, or dullness on the surface, there a lot of ways to fix the problem and repair your sink. The process is simple and easy to complete.

Repair Preparation

Clean the surface of the entire sink so that no dirt or debris gets in the way of the repairing process. Sand the surface of your sink until it is smooth. Sanding allows the repair solution to stick onto the surface for a longer period of time.

Tools and Materials

You can purchase a repair kit and the necessary tools at your local home improvement store for around $30. You will need a filler, which is a paste-like substance that will fill and cover the areas of your sink that may have patches, cracks, or other damage. You will need some gloss or a clear glaze. If you choose a gloss or glaze with color, make sure that it matches the color of your porcelain sink. It will be the finishing touch.

Repairing the Sink Damage

Use a spatula or any flat blade to apply the filler paste to the damaged porcelain. Consult the manufacturer’s instructions for the proper drying time. Once the paste has dried completely, sand the spot the paste until the surface is smooth.

Only sand the area of the sink with paste on it, and not the others. Then use a thin paintbrush to coat the areas with the gloss until the whole surface is equal in color and looks like new.

Final Instructions

Once the repairs have been made, allow the finished product to rest so that all of the product will dry and set properly. Make sure that none of the repaired spots gets wet. Review your manufacturer’s manual or user's guide for proper instructions on how long the finishing coats need to dry.
