How to Refinish Powder Coated Aluminum Patio Furniture

Powder coating is a durable and long-lasting finish that is often applied to aluminum patio furniture. However, over time, the powder coating can become scratched, faded, or chipped, diminishing the furniture's aesthetic appeal. Refinish your powder coated aluminum patio furniture to restore its beauty and extend its lifespan. This guide provides a comprehensive overview of the process, from preparation to application.

Preparing the Furniture for Refinishing

Proper preparation is crucial for a successful refinishing project. Begin by thoroughly cleaning the furniture to remove dirt, grime, and any loose powder coating. A mild soap solution and a soft brush or sponge are usually sufficient. For stubborn stains or residue, consider using a degreaser or a specialized cleaning solution designed for powder-coated surfaces.

Once the furniture is clean, inspect it for any loose or flaking powder coating. Use a scraper or a wire brush to remove these areas. Sanding may also be necessary to smooth out rough edges and create a suitable surface for the new finish. Start with coarse-grit sandpaper (80-120 grit) and progressively move to finer grits (220-400 grit) to achieve a smooth finish. Remember to wear appropriate safety gear, including gloves, a mask, and eye protection during sanding.

Applying the New Finish

After preparation, you can apply the new finish. There are several options available, each with its own advantages and disadvantages.

Powder Coating

The most durable option is to re-powder coat the furniture. This process involves applying a new layer of powder coating to the cleaned and prepared surface. It typically requires professional equipment and expertise, making it best suited for large-scale projects or when seeking a factory-like finish. The powder coating is then cured in an oven at high temperatures, resulting in a hard, chip-resistant finish. This method is ideal for restoring the furniture to its original appearance and extending its lifespan.

Spray Paint

A more DIY-friendly alternative is using spray paint. Choose a high-quality spray paint specifically designed for aluminum surfaces. Follow the manufacturer's instructions for preparation, application, and drying time. Apply thin, even coats, avoiding drips and runs. Multiple thin coats are generally preferred over a single thick coat to ensure a smooth, consistent finish.

Rust-Oleum High Heat Spray Paint

A popular option for refinishing aluminum patio furniture is Rust-Oleum High Heat Spray Paint. This paint formula is specifically designed to withstand high temperatures and offers excellent durability and protection. Its high-heat tolerance makes it suitable for both indoor and outdoor applications. It is available in various colors to match your aesthetic preferences.

Final Touches

After the new finish has fully cured, consider applying a sealant to further protect it from the elements. A clear polyurethane sealant will provide additional durability, enhance the finish's shine, and make it easier to clean. Follow the sealant's instructions for application and drying time.

Finally, clean and polish the furniture to remove any dust or residue. Enjoy your newly refinished patio furniture for many years to come. Regular maintenance, such as cleaning and applying a protective sealant periodically, will help to prolong the finish's lifespan.
