How to Repair a Porcelain-Covered Sink
A porcelain sink usually has a cast iron base with the porcelain baked over it in a thick layer that provides its trademark glossy finish. Cracked or chipped porcelain looks bad and, if the damage is deep enough, it can even cause the underlying cast iron to start rusting. Minor porcelain damage is something you can repair with a little epoxy glue, which dries as hard as rock and can be painted. Does this Spark an idea?

1
Prepare the epoxy glue as instructed on the container, mixing the two parts to activate the adhesive. Make only as much as you need to repair the surface of the sink.
-
2
Spread the epoxy glue over the damaged porcelain. Work it into the cracks or chips with a toothpick.

3
Run a rag lightly over the glue to smooth it out and remove it from the undamaged parts of the porcelain. Let the glue dry overnight.
-
4
Sand the surface of the glue with fine sandpaper, using quick, light strokes to get it smooth and flat. Run your hand over the porcelain after sanding; you should feel no variation in the surface.
-
5
Cover the glued areas with a thin coat of paint, using an art paintbrush. Get the paint very flat and keep it on the surface of the glue, not on the porcelain around it.
-
6
Let the paint dry for four to six hours. Cover it with a thin layer of polyurethane, brushing it on over the glue surface. Let the polyurethane set for a full day before using the sink.
