What type of media for sandblasting aluminum prior to powdercoating


Q. Hello,

I have some aluminum motorcycle parts that will be powdercoated. I am planning of sandblasting the parts. What is the best type and grit of media that should be used.

A. Well you should start off with a rough media such as sand or "Black Beauty"[linked by editor to product info at Amazon] , then move to a more fine media such as glass. This ensures your paint will stick to the aluminum's surface with ease instead of peeling.

A. Aluminum Oxide is my favorite for doing aluminum parts, but black beauty will work just fine if you use the 30-60 product(extra fine) and keep the pressure low to prevent distortion (read-warpage). I do not use glass beads as this product is not angular, and will only peen the surface, not etch. A uniform etch will provide superior surface area for the powder to adhere.
