It’s important to refinish rusty decorative ironwork or steel on your house as soon as possible to prevent the metal from corroding more.

To refinish rusty wrought iron or steel:

  1. Remove Rust: Use a wire brush or rotating wire drill attachment to remove all the rust from the surface of the metal.
  2. Clean Surface: Wipe down the metal with mineral spirits to remove any rust dust.
  3. Prime Metal: Spray the cleaned metal surface with rust inhibiting primer.
  4. Paint Iron: When dry, apply several light coats of finish paint to the metal.

The first step to repainting rusty ironwork is removing the rust. A wire brush, or wire brush attachment for your drill, will get the job done. Remove the remaining dust by wiping it down with mineral spirits. Now, spray the affected ironwork with a rust inhibiting primer, and allow it to dry well before applying two or three coats of the finish paint. Remember several light coats are better than one thick coat.

  1. Im stumped, have painted my iron gallery twice and rust is still popping its ugly head out . I have grinded right down to bare metal primed and painted, both two coats . can you suggest something I could try, never had this problem before feeling like a amature.

  2. I HAVE A 40′ BY 50′ ALL STEEL GARAGE . WE HAD ONE OF MY TRUCKS GROUND CABLE WAS TOUCHING THE FRAME , IT CAUGHT FIRE AND BURNT UP ALL FIVE OF MY TRUCKS. 01/31/2018
    EVERYTHING IS METAL BEAMS NO WOOD . CAN I USE A POWER WASHER TO BLAST OFF THE RUST AND PAINT THE BEAMS WITH
    BRIDGE PAINT ? THEN RESKIN THE HOLE BUILDING INSTEAD OF TEARING THE WHOLE THING DOWN.

    • Hi, Michael,
      Depending on the heat of the fire and thickness of the steel framing, there’s a possibility of metal fatigue, but you should contact an engineer to visit the site in person and make that determination.
      Good luck!
