Can I Paint Over the Old Metal Awnings on My House?

Consistent upkeep helps maintain your metal awning and boosts curb appeal.

Your metal awning provides shade on hot days and adds an interesting architectural detail to your home’s exterior. Unfortunately, years of exposure to sunlight, rain and wind causes the metal awning to rust and fall into disrepair. Instead of pulling down the awning and replacing it, slap on a fresh coat of paint to bring it back to life. With the correct tools and preparation it is possible to paint your existing metal awning without the need for professional assistance.

Things You'll Need

• Pressure washer
• 220-grit sandpaper
• Tack cloth
• Rust-inhibiting primer
• Paint rollers

Instructions

1. Remove any remaining paint, dirt, grime and chalk from the metal awning with a pressure washer. Holding the washer’s nozzle with both hands, remove this build-up and any loose rust from the awning to ensure the paint adheres more effectively.

2. Allow the awning to dry completely and sand the metal with 220-grit sandpaper. Work the sandpaper over the metal to remove any remaining paint chips and rust from the surface.

3. Wipe down the awning with a tack cloth to remove any dust or debris created by the sanding.

4. Cover the metal awning with a thin layer of rust-inhibiting primer. Apply a light coating of the primer with a paint roller and allow it to dry completely or at least 24 hours, before continuing.

5. Apply a thin coating of acrylic latex or acrylic enamel paint. Once again, roll on a thin layer of the paint and allow it to dry for at least eight hours, or overnight, before applying a second, and if necessary, third coat.

Tips & Warnings

• Choose a day that is overcast and has no precipitation in the forecast to paint your metal awning.

• Clean the awning with a mildew-inhibiting product if there is mold formation before priming and painting.
