Restore Antique Cast Iron Sinks

Cast iron sinks develop oxidation rapidly when exposed to moisture and air. An antique cast iron sink that has developed rust requires immediate action to prevent further damage. Preserve the sink and restore it to its original state by removing old paint and rust and applying a fresh coat of paint to seal the sink and protect it from future damage. Does this Spark an idea?


1. Use a palm sander to sand the entire sink with medium-grit sandpaper to remove old paint and rust. Move the sander in a circular motion to effectively sand all surfaces. Remove sanding dust with a slightly damp cloth. Do not rinse the sink with water, as it will cause rust to form on the cast iron. Allow the sink to dry for ten to fifteen minutes.

2. Apply an epoxy primer with a paintbrush as soon as the sink is dry. If primer is not applied in a timely manner, new rust may form. If new rust has developed, remove it with a wire brush prior to applying primer. Use an adequate amount of paint on the brush, and paint smooth, even strokes to prevent brush marks. Wait for the primer to dry completely.

3. Add a topcoat of acrylic paint in a similar manner. Do not leave visible brush strokes. Allow the paint to cure for five days. After five days, the sink is ready for normal use. Do not use abrasive cleaners to clean the restored sink. Wipe with a soft cloth and non-abrasive cleaner as needed.
