If your ceramic sink is looking a little worse for wear, reglaze or refinish it to give it a new look. Also known as resurfacing, reglazing a sink follows the same process and uses the same tools as reglazing or refinishing a bathtub. Although the reglazing on your sink will typically not keep its shine as long as a new sink would, it can extend a sink's life at less than half the cost of a new model.
Scrape away any caulk around the sink using a putty knife or scrape. If the sink is attached to a base or cabinet, remove it from the piece. Remove the faucet and sink plug. Set the sink on plastic or newspapers.
Apply an acid-based commercial cleaner to the surface of the sink. Follow the manufacturer's instructions for the use of the cleaner. Let the cleaner sit for 5 minutes. Scrub the sink with an abrasive cleaner. Rinse the cleaner off. Dry the sink with a soft cloth, or let it air dry.
Use a scrub brush to apply an acid-etching paste to roughen the surface of the sink. If you don't have acid paste. sand the surface of the sink with sandpaper. This gives the paint something to hold.
Rinse off the surface of the sink after 15 minutes, if you applied etching paste. No wait is needed between sanding and rinsing.
Spray the surface of the sink with an epoxy acrylic primer. Apply the primer in thin coats to keep it from building up. Let the primer dry overnight, so it has a chance to harden.
Spray the surface of the sink with an acrylic paint and polyurethane topcoat. Apply the topcoat in thin, even coat to keep the paint from becoming too built up. Leave the paint to dry overnight, so it can harden.
You can purchase a paint and polyurethane topcoat mixture for bathtubs and sinks at most home improvement stores. Read the manufacturer's directions regarding primers and topcoats before applying to your sink. Some epoxy primers and topcoats have longer required drying times than others.
Do not use abrasive cleaners, such as sink scrubs, after reglazing your sink. The abrasive elements in the cleaners can cause the surface to deteriorate or become pitted.
