Over time, aluminum siding can start to look faded, chalky, or outdated. Instead of replacing it, painting your aluminum siding is a cost-effective way to refresh your home’s appearance and boost curb appeal. With the right preparation and materials, you can achieve a long-lasting, professional-looking finish. Here’s a complete guide to help you through the process.
Step-by-Step Guide To Painting Aluminum Siding

- Prepare a cleaning solution with water, bleach, and TSP (trisodium phosphate).
- Scrub the siding thoroughly from bottom to top with a soft brush or sponge.
- Rinse thoroughly with a hose or pressure washer.

- Sand the Siding
- Use fine-grit sandpaper to lightly sand the surface.
- Remove any remaining chalky residue or rough patches.
- Avoid heavy sanding to protect the integrity of the aluminum.
- Protect Surrounding Areas
