Can You Paint the Exterior of a Cast Iron Sink
For cast iron sinks, choose a paint that can withstand constant exposure to water and wear. Epoxy-based paints are a great choice as they provide a durable, waterproof finish. You can use an epoxy-based or oil-based enamel paint, and oil-based metal primer paint for cast iron sinks. Use these types of paints for a consistent finish that will stick to the base, and will withstand contact with water over time.
