Wrought iron gates, railings, and fences are part of nearly every Spanish and Mediterranean-style home in south Orange County. Salt air and moisture cause rust. UV exposure fades the finish. Proper painting stops the corrosion and restores the appearance for 5 to 8 years.

Why Wrought Iron Rusts in Orange County

Wrought iron is steel. Steel oxidizes when exposed to moisture and oxygen. Coastal Orange County homes within five miles of the ocean face accelerated corrosion from salt air. Inland homes rust slower but still develop surface oxidation within a few years of the last paint job.

Rust does not stop on its own. Once it starts, it spreads under the paint film and causes flaking and pitting. The only fix is removing the rust mechanically and recoating with a rust-inhibiting system.

How to Paint Wrought Iron Correctly

Wire brush or sand all visible rust down to bare metal. Apply a rust-inhibiting primer like Sherwin Williams Pro Industrial DTM or Rust-Oleum Clean Metal Primer. Let the primer cure fully. Topcoat with two coats of semi-gloss or gloss acrylic enamel for maximum durability and UV resistance.

Spray application produces the smoothest finish on wrought iron. Brush application works for small areas and touch-ups. The key is thin, even coats. Heavy coats drip and pool in the decorative curves and joints.

What Wrought Iron Painting Costs

Wrought iron painting starts at $300 to $800 for gates and railings in Orange County. Stair railings and small sections cost less. Full perimeter fencing runs higher based on linear footage and the amount of rust removal needed. Heavily corroded iron with pitting requires more prep and costs 30 to 50 percent more than surface-level rust.

How Long the Finish Lasts

A properly prepped and painted wrought iron surface lasts 5 to 8 years in Orange County. Coastal homes may need touch-ups at the 3 to 4 year mark on high-exposure areas. The primer is the most important layer. Without rust-inhibiting primer, even premium topcoat will fail within two years.
