A Comprehensive Guide to Applying Powder Coat: Steps and Best Practices

Updated: Jan 8, 2023

Powder coating is a popular finishing process that involves applying a-dry, powdery paint to a metal surface and then curing it under heat. The result is a smooth, durable finish, resistant to chipping, fading, and scratching. Powder coating is often used on automotive parts, furniture, and home appliances, as well as on a variety of other metal products.

If you are interested in learning how to apply powder coat, the following steps will walk you through the process:



  1. Clean the surface: The first step in the powder coating process is; thoroughly clean the item you will be powder coating. This is important because any dirt, grime, or contaminants on the surface can affect the adhesion and overall appearance of the finished product. Use a degreaser or metal cleaner to remove any dirt or oils.

  2. Media Blast or Sand the surface: If there are imperfections, such as scratches or dents, you will need to sand them down before media blasting (or if you are only sanding) before applying the powder coat. Use medium-grit sandpaper or blasting media, like 70/30 Green Diamond nickel slag. Then use compressed air to blow off any dust and debris.

  3. Apply the powder coat: Use an electrostatic powder coating system that gives the powder a positive charge when applying. Connect an earth-ground to the metal surface you are powder coating, giving it a negative charge. This will cause the powder to be attracted to the metal surface and adhere to it.

  4. Cure the powder coat: Once the powder-coat has been applied, it needs to be cured to fully harden and bond to the surface. This is typically done in an oven or with an infrared curing lamp. The curing temperature and time will depend on the specific type of powder coat that you are using, so be sure to follow the manufacturer's recommendations.

  5. Inspect: After the powder coat has been cured, inspect the surface for imperfections or missed spots. If there are missed or light spots, the item will need to be stripped and start the process.


There are a few things to keep in mind when applying powder coat.

  1. It is important to use the correct type of powder coat for the specific application. Powders are formulated for an array of surfaces and environments. Be sure to choose one that's suitable for your needs.

  2. Follow the manufacturer's instructions and use the proper safety equipment, such as gloves, masks, and eye protection. Finally, properly prepare the surface and apply the powder coat evenly to ensure the best possible results.

Powder coating is a versatile and durable finishing process that can be used on a range of metal products. With a little practice and the right tools, you can achieve professional-quality results from the comfort of your own workshop.
