Rust spots on a metal outdoor sofa frame can be unsightly and weaken the structure over time. Fortunately, repairing them is a straightforward DIY project. Follow these steps to restore your furniture:

1. Assess the Damage: Identify the rusted areas and check for deep corrosion. Minor surface rust is easier to fix.

2. Gather Supplies: You’ll need sandpaper (80-120 grit for heavy rust, 220 grit for smoothing), a wire brush, rust converter or primer, matching paint, and a clear sealant.

3. Remove Loose Rust: Use the wire brush or sandpaper to scrub away loose rust and flaking paint. Wipe the area clean with a damp cloth.

4. Apply Rust Converter (if needed): For stubborn rust, apply a rust converter to stop further corrosion. Let it dry as per the product instructions.

5. Sand Smoothly: Lightly sand the area to create a smooth surface for painting. Wipe away dust afterward.

6. Prime and Paint: Apply a metal primer to prevent future rust. Once dry, paint with a color-matched outdoor-grade paint.

7. Seal the Repair: Finish with a clear sealant to protect the paint from weather damage.

Regular maintenance, like cleaning and occasional touch-ups, will keep your metal sofa rust-free for years.
