DIY Powder Coating Systems
- 1). Select your metal-only parts for powder coating. The most important aspect of powder coating is that the metal be clean and solvent-free to allow the powder to bond with the surface. Use a degreaser to throughly clean the part, then clean with soap and water. Avoid using strong solvents such as a brake cleaner, carb cleaner, or paint thinner.
- 2). Fill the gun from your powder coating kit with powder and, using an even back and forth motion, coat the metal part. The powder will even out during baking so just make sure you cover all parts of the metal surface.
- 3). Place the parts into an electric oven for baking. The powder you use will instruct you how long, but generally expect to bake the parts at 375 F for 8 to 10 minutes. Remove from the oven and while the metal is still hot, re-coat with a second layer of powder and re-bake.
- 4). Remove from the oven and if you want to shoot a clear coat over the part, shoot while the metal is still hot. Bake for a final cycle, then allow the metal to sit and cool for an hour.
