Ensure all parts are accounted for and stored safely to facilitate easy reassembly after refinishing.

Cleaning the Metal Surface

Before you start refinishing your outdoor metal furniture, preparing the metal surface properly is crucial. This includes thoroughly removing any rust and cleaning the surface to ensure the new finish adheres well.

Eliminating Rust

  • Use a wire brush: Scrub the rusted areas vigorously with a wire brush to remove as much rust as possible.
  • Apply a rust converter: If the rust is widespread, apply a rust converter with a paintbrush, which will chemically convert the rust into a primer.
  • Use sandpaper: For tougher spots, use medium-grit sandpaper. Sand the areas until you reach the bare metal.

Washing and Degreasing

  • Create a soapy solution: Mix a few drops of mild dish soap into a bucket of warm water.
  • Wash the surface: Dip a sponge in the soapy water and clean the entire metal surface to remove dirt and any remaining rust particles.
  • Rinse with water: Use a hose to rinse off the soap. Avoid using a pressure washer as it can damage the metal.
  • Dry thoroughly: Wipe the furniture with a clean cloth and allow it to dry completely to prevent rust from reforming.
  • Apply a degreaser: For any remaining oily spots, apply a commercial degreaser and follow the manufacturer's instructions, then rinse and dry again.

Preparing the Surface for Refinishing

Proper preparation of the surface is crucial for achieving a long-lasting, quality finish on outdoor metal furniture. The process involves thorough sanding to remove rust and old paint, followed by the application of a suitable metal primer to ensure good adhesion of the new paint.

Sanding for Smoothness

Start by removing any loose paint or rust from your metal furniture using a wire brush or a sanding block with medium-grit sandpaper (60-80 grit). For areas with more substantial rust or old paint, you may need to use a power sander. Always wear safety goggles and a dust mask for protection. Sand the surface uniformly until the metal appears dull and is free of rust and flaking paint.

  • Materials Needed:
    • Wire brush
    • Sanding block or power sander
    • Medium-grit sandpaper (60-80 grit)
  • Safety Equipment:
    • Safety goggles
    • Dust mask

Applying Metal Primer

After sanding, clean the surface with a damp cloth to remove all dust and debris. Once dry, apply a rust-inhibiting metal primer to all surfaces of the furniture. Use a primer that is specifically designed for exterior metal surfaces and apply it using a brush or a spray applicator for even coverage. Let the primer dry as per the manufacturer's instructions before proceeding with painting.

  • Steps:
    1. Clean the surface with a damp cloth.
    2. Apply rust-inhibiting metal primer.
    3. Let it dry completely.

Painting the Metal Furniture

Before choosing paint or beginning the application process, it is essential to know that the success of your project depends heavily on the type of paint you use and the application technique.

Choosing the Right Paint

  • Type of Paint: Opt for paints specifically formulated for metal surfaces. These typically come as spray paints or liquid paints for brush applications. Examples include acrylic, epoxy, and oil-based paints. They should be rust-inhibitive and suitable for outdoor exposure.
  • Finish: Choose between gloss, semi-gloss, satin, or matte finishes depending on the desired look and the ability of the paint to protect against the elements.
  • Color: Select a color that can resist fading from UV exposure and is consistent with outdoor aesthetics.

Technique for Even Coating

  1. Surface Preparation: Start with a clean, dry, and sanded surface for better paint adhesion.

  2. Priming: If using liquid paint, apply a metal primer with a brush or roller to enhance paint durability and corrosion resistance. Allow it to dry completely.

  3. Application:

    • For spray paint: Hold the can approx. 10-12 inches away from the furniture. Use steady, even strokes, and apply multiple thin coats rather than one thick coat to avoid drips.
    • For brush-on paint: Use a high-quality brush or roller. Apply paint in thin, even layers. Work systematically across the furniture to prevent missed spots and overlap the paint edges for full coverage.

  4. Drying Time: Observe recommended drying times between coats. This can vary depending on the paint type and environmental conditions.

  5. Sealer (Optional): For extra protection, apply a clear sealer once the final paint coat has dried.

Reassembling the Furniture

Before reassembling, ensure all pieces are dry and free from dust. Lay out your furniture parts on a clean, soft surface to avoid scratching the newly finished metal.

Tools Required:
