The aluminum tool box has a corrosion-resistant aluminum oxide coating to prevent rust. This oily substance is effective against corrosion, but it will hinder the adhesion of the bonding primer and paint. Inadequate preparation will cause the paint surface to crack, peel and peel under extreme conditions. You don't want to paint your toolbox every month; spend some time in the preparation phase to ensure the quality of the finish.
Step 1
Clean and degrease the entire surface of the toolbox. Alumina will quickly transform on the surface, so prepare the surface and paint in the same day.
Step 2
Use 80 grit sandpaper to polish the surface of the tool box to make it scratched. If you want a showroom surface, sand the surface with finer sandpaper-the etching primer uses these scratches to penetrate the aluminum surface and drill holes in it.
Step 3
After sanding, clean the toolbox with a degreasing cleaner. Dry the surface with a tack cloth to remove small particles. Dust or metal particles can cause paint to peel off and rust. If the surface feels smooth or greasy, repeat these steps until you break the aluminum oxide coating.
Step 4
Dip the cloth in rubbing alcohol and wipe the tool box clean. Before applying the etching primer, let the alcohol evaporate from the surface.
Step 5
Shake the spray of the etching primer vigorously for two minutes. Apply two even coats of etching primer. Apply every five minutes. This can make the etching primer "flash off" or start a chemical synthesis process-the etching primer should be cured for 20 minutes before painting.
Step 6
Paint the toolbox at high temperature or all-weather. Follow the instructions on the sprayer to lightly apply an even coating. Let each layer of paint cure before proceeding to the next layer. Your toolbox will be exposed to inclement weather and temperature throughout the year. Using coatings that can withstand these conditions can prevent peeling and scaling.
Spray on the seal of high-quality paint. Lacquer seals or clear lacquers with different gloss levels can be purchased. In order to achieve a truly flat surface effect, you can paint on the surface, and use a steel wool pad to polish off the gloss.
