Contenu
All aluminum surfaces are susceptible to corrosion, especially on aluminum objects such as cars and patio furniture. As soon as you notice the aluminum has corroded, you should do what you can to get rid of it. Gather all of the supplies you need and then get to work.
Step 1
Put on all of your safety gear and do not remove any articles of protection until the project is complete. Plug the sander into the closest outlet.
Step 2
Remove some of the corrosion on the aluminum by using the sander. Move it in circular motions until you see the corroded pieces begin to slough off. This will also help smooth out the surface for repair.
Step 3
Use the wire brush to scrape off any excess corrosion.
Step 4
Apply a small amount of phosphoric acid gel to a soft cloth and gently rub it onto the corroded area in a circular motion. Allow the gel to sit on the area for about 10 minutes. Wipe it off with a dry cloth, but do not continue to rub it in.
Dip the sponge paintbrush into the anti-corrosive primer and slowly swipe it over the damaged area. Allow the primer to dry for 24 hours.
Tip
- Phosphoric acid gel turns rust and corrosion into a water-soluble phosphate compound, which makes it easier to clean off of any metal surface.
