- Aluminum oxide sandpaper (120-grit for removing heavy corrosion, 220-grit for prepping the surface, and 400-grit for smoothing)
- Aluminum etch solution
- Aluminum primer (specifically for aluminum)
- Spray paint (any color; Rustoleum offers several spray paint specifically for aluminum)
Tools:
- Orbital sander
- Safety glasses, gloves, and a face mask
Instructions:
1. Prepare the Surface:
- Use the orbital sander with 120-grit aluminum oxide sandpaper to remove heavy corrosion.
- Sand the entire surface of the window frame to create a uniform texture.
- Move on to the 220-grit sandpaper to prep the surface for painting.
2. Apply Aluminum Etch Solution:
- Apply the aluminum etch solution following the instructions on the product label.
- This solution will further clean the surface and enhance paint adhesion.
3. Rinse Thoroughly:
- Rinse the window frame thoroughly with water.
- Allow it to dry completely.
4. Apply Aluminum Primer:
- Use a brush or spray to apply the aluminum primer to the window frame.
- Make sure to cover all surfaces.
- Let it dry according to the manufacturer's instructions.
5. Sand the Primer:
- Once dry, use the 400-grit sandpaper to lightly sand the primer.
- This creates a smooth surface for painting.
6. Apply Spray Paint:
- Choose a spray paint specifically designed for aluminum. Rustoleum offers several options.
- Spray the paint in thin, even coats. Allow each coat to dry completely before applying the next.
- Apply multiple coats to ensure complete coverage and durability.
7. Let It Dry:
- Allow the final paint coats to dry thoroughly before reinstalling the window frame.
8. Reinstall the Window Frame:
- Once the paint is completely dry, reinstall the window frame into its original location.
By following these steps, you can effectively repair aluminum corrosion in window frames, restoring their appearance and protecting them from further damage.
