Spray painting outdoor metal furniture is an easy and cost-effective way to give your furniture a new lease of life, to match your house’s exteriors or just to get a new look. Metal furniture can be vulnerable to rust and corrosion, but the right preparation and paint choice can keep it looking great for years.

Here are some tips for spray painting your outdoor metal furniture:


1. Clean the surface: Before you start painting, make sure that the surface is free from dirt, grease, rust or any other debris. Use soap and water to clean the furniture, and a wire brush to remove any loose paint or rust.

2. Sand the surface: Sanding the metal furniture is important because it helps to create a rough surface that the paint can adhere to. Use a sandpaper with a grit of 220-320 to sand the surface.

3. Protect the surroundings: Cover the surrounding area with drop cloths or plastic sheets to prevent paint from getting on them. This is especially important if you are painting outside, where the wind could carry paint droplets further than you intended.


1. Choose the right paint: Select a paint that is formulated for outdoor use, such as a rust-inhibiting enamel. There are spray paints specifically designed for metal furniture with rust inhibitors that will keep the paint from cracking or peeling.

2. Apply a primer: Applied to the surface before painting, the primer helps to improve adhesion, prevent rust, and protect the underlying metal. Follow the manufacturer's instructions to apply a suitable primer.

3. Apply the paint: Hold the spray paint can about 8-12 inches away from the surface and apply the paint in even strokes. Apply in thin layers and allow each coat to dry before applying the next. It’s better to apply multiple thin coats of paint than one thick one.

4. Don’t touch up: It can be tempting to touch up missed spots or uneven sections mid-process, but it’s essential to wait until the previous coat is completely dry before applying another to avoid ruining the finish.


1. Give it time to dry: Allow the painted surface to dry for at least 24 hours before using the furniture.

2. Regular cleaning: Clean the surface regularly to keep it looking new. Use mild soap and water to clean the surface, and avoid using abrasive cleaners or scrubbing too harshly.

With proper preparation, painting, and aftercare, you can give your outdoor metal furniture a beautiful, long-lasting finish.
