How to paint metal surfaces

When you’re renovating, the devil is in the detail. Taking the time to restore and protect your metalwork can add the perfect finishing touch to your home.

  1. Before you get started, you’ll need to prep your surface. Remove any rust, loose, flaking or peeling paint with a wire brush or coarse sandpaper.

  2. Next, clean the surface with Dulux Metalshield Brush Thinner to remove any grease, oils and dirt. Once clean, be sure to wipe the brush thinner off the surface with a cloth.

  3. With a clean metal surface ready to go, it’s time to prime. Different metal surfaces require different primers, so be sure to choose the right one.

    New or Painted Galvanised Iron or Zincalume: Dulux Metalshield RFU Etch Primer

    All other New or Painted metal surfaces: Dulux Metalshield All Surface Primer

    Steel, wrough iron and damaged galvanized iron under severe corrosive conditions: Dulux Metalshield Gold Galv Primer

  4. Once you’ve found the appropriate primer, stir it thoroughly with a broad, flat stirrer using a lifting action. Then load up your brush and apply a single, even coat.

  5. Once your primer is dry, it’s time to paint and protect your metal. To ensure your handy work is protected against rust, corrosion and the elements we recommend using Metalshield Premium Topcoat.

  6. Apply one clean, even coat and leave it to cure for 24 hours before applying a second coat. Wrap your brush or roller in cling wrap to prevent them drying out while you wait. Leave the final coat to dry for 3 hours before handling.

    for hard to reach or detailed projects, use our range of Metalshield spraypaks. For details on how to spray paint see our step-by-step guide.

  7. New, bare steel, wrought iron and pre-painted surfaces don’t need to be primed. Simply give them a clean as above, and then paint with your chosen tint of Dulux Metalshield Epoxy Enamel.
