One of the most important steps to take before painting or powder coating any piece is to make sure its properly cleaned and anything remaining is removed. Sand blasting is a great way to completely remove any and all impurities that may be resting on the metal.

Sandblasting is the most common form of media blasting, you are essentially using compressed air and sand to strip the metals clean and give it the profile the powder needs to stick.  If you have ever used sandpaper, it is essentially the same idea.  Although sand is the most common, everything from glass, to steel and walnut shells are used for all kinds of different substrates.

Sandblasting is one of the most important steps in the paint and powder coating process, assuming your substrate can withstand blasting. It not only cleans the piece, it creates a profile in the metal which promotes adhesion. In addition to the finished product looking better, it will last much longer and function properly.
