How to Powder Coat a Frame
Powder coating is the process in which dried paint particles are electrostatically charged and sprayed on to your frame. The final product is the same as having two coats of cured wet paint on the surface. This method is fairly new to the painting world, first applied in Australia in 1967. With good preparation, powder coating will give you a solid painted surface that will stand up to the elements.

Sand away any oxidation or previous paint coatings from your frame. Start with the heavy grit sandpaper if you need to remove layers of paint. Sand the frame again with the medium grit sandpaper to remove any scratches. Wet sand the frame with the fine grit sandpaper to prepare the surface for a smooth paint job.
2Wipe the frame down with tack cloth to remove all dust and particles.
3Attach the ground wire from your powder coating gun to the hanging rack. This ground loop will attract the charged paint particles to your frames surface.
4Plug the power cord for your powder coating gun into a nearby electrical outlet. This will allow the gun to charge the paint particles as they are blown onto the frames surface.
5Connect your powder coat gun to the air supply hose from the air compressor.
6Turn on the air compressor and let it charge for three minutes to build up pressure.
7Fill your paint sprayer with powder coating.
8Spray the frame evenly until all surfaces are coated.
9Place the frame in the oven at 400 degrees and allow it to bake for 15 minutes.
10Remove the frame from the oven carefully using the gloves. Allow it to cool down before handling.
