Whether you have products made from aluminum, steel or another metal, priming will help extend the life of your product and coating. Aluminum provides natural resistance to rust and corrosion. Still, if it comes into contact with another metal part or product with conflicting properties, your products can suffer rapid deterioration due to corrosion. Steel and other metals are cost-effective and easy to work with, but when exposed to the elements, they will start to rust fast, destroying your product and the coating.
At Keystone Koating, we use an in-line priming system to apply high-quality primers with minimal additional lead time. Our experts know which primers to match with your metals to ensure you gain the maximum advantage, and we only use products from leading manufacturers. For steel products, we use a zinc-rich primer that acts as a galvanizing agent, preventing corrosion from taking hold and strengthening the bond with your powder. For aluminum, our non-zinc primer helps block metal-on-metal contact to stop galvanic corrosion.

Powder coating can last for decades with the right surface preparation, application and powder. Before you coat any metal part, you will want to speak to an expert to ensure you apply a powder capable of withstanding the conditions you are going to put your products through. If your products are intended for use outdoors or under prolonged exposure to sunlight, consider using a primer coat to extend the lifespan of your coating. Ask about our Super Durable Powder made for extra tough climates. And for architectural metal applications, we offer KEYCOAT20, a 20-year limited warranty on AAMA 2605 projects.
From start to finish, we use trusted products and processes to ensure quality work you can depend on for years. With over 30 years of experience in the industry, we know which types of powders perform best under any conditions. We use our expertise to make sure your coating exceeds all your expectations. Schedule regular cleaning and maintenance using our suggested methods to help extend the life of your powder coating.
How do I properly clean and maintain powder coating?
Some basic tips:
- Avoid excessive contact. Approach with an attitude of “less is better!”
- Avoid harsh, abrasive cleaners such as steel wool and scourers. Treat powder coating as you would your car paint.
- Avoid solvents where possible, When a solvent is absolutely necessary to remove materials from the surface, such as adhesives, the weakest possible solvent should be used (e.g. methylated spirits, white spirits or isopropyl alcohol). A small and unobtrusive area should be tested prior to attempting to use solvents on significant surfaces. After removal of the surface contaminant, the solvent should be dried from the film, and the area that has been wiped with solvent should be washed with a solution of mild liquid detergent and then rinsed with clean water to ensure complete removal of any solvent residues. Under no circumstances should strong solvents be used. Examples of inappropriate chemicals for cleaning or for any contact with powder coating are gasoline, kerosene, MEK, xylene, caustic cleaners like kitchen and bathroom detergents, and paint thinners. Always flush metal that has been exposed to cleaners with copious amounts of fresh, clean water.
- When a scratch is discovered, it should be addressed immediately. If bare metal is exposed, it should be lightly sanded with a 180 grit or finer sandpaper to remove any corrosion that may be present. Then the sanded area should have all sanding debris removed with either a clean brush or compressed air. The surface can then be touched up with a liquid paint; we recommend a high quality architectural or automotive grade paint, enamels or two part urethane.. Two or three coats of paint are usually required to achieve adequate coverage. For larger areas a liquid primer is recommended.
