Things You'll Need
Coarse and fine-grit sandpaper
Oil-based rust inhibiting primer
Patio furniture is exposed to outdoor conditions on a daily basis. Exposed to too much moisture, the reddish-brown corrosion called rust develops on the furniture. Left unabated, the rust will continue to eat at the furniture, sometimes causing holes in the metal. Repair rusted patio furniture yearly or when you notice it to prevent further corrosion.
Scour rusted areas with a wire brush. Continue scrubbing the areas until all rust and loose paint chips away.
Sand the patio furniture with coarse-grit sandpaper, and then sand the furniture with a fine 120- to 180-grit sandpaper. Sand all matching furniture pieces if the item is part of a set.
Wipe the sand and paint residue off the furniture using a clean cloth soaked in warm water. Repeat if necessary. Dry the furniture completely.
Apply an oil-based rust-inhibiting primer to the patio furniture. Use a brush-on primer to ensure complete coverage. Allow to dry completely.
Paint the furniture. Check the paint's labeling to ensure that it is approved for outdoor use and compatible with the oil-based primer. Apply more coats as necessary, allowing each to dry completely before applying another.
