Paint Rusty Iron Railings

Seal rust with an iron oxide primer.

Unless they are galvanized, metallic surfaces will ultimately rust when exposed to oxygen and moisture. If left untreated, the rust will consume the railings, resulting in complete decomposition. You can preserve your railings and enhance their appearance by coating them with the appropriate type of paint. First, you must apply a particular type of primer, capable of covering the rust and preventing future outbreaks. Improper surface preparation will not only lead to a lackluster finish, but it will result in certain rust recurrence.


1. Wash the iron railing with a pressure washer. Wait one to three hours for the railing to dry.

2. Put on protective gloves.

3. Remove loose rust, using a wire brush. Remove smaller particles with 80-grit sandpaper.

4. Cover the surface beneath the iron railing with fabric drop cloths. Apply painters tape to portions of the railing you do not plan to paint.

5. Coat the rusty iron railing with an iron oxide primer, using a mini roller. Coat areas inaccessible to the roller, using a 2- to 3-inch paintbrush, manufactured for applying oil-based coatings. Wait two hours for the primed railings to dry.

6. Wash your painting tools with mineral spirits.

7. Coat the primed iron railing with an oil-based enamel, using the clean mini roller. Wait two hours for the finished railings to dry. Use the paintbrush to touch up the railing where you have inadequate coverage.
