Surface preparation is the process of prepping a metal for the application of a variety of different coatings ranging from powder sprays to thermal sprays to paints. Surface preparation is an essential part in preparing a metal for finishing because the performance of the final coating very much depends on how well the surface was prepared. Surface preparation commonly uses an abrasive such as aluminum oxide that is blasted through a wet or dry pressure blasting system. This process removes the containments and unwanted substances from the metal's surface in order to produce a clean surface that will promote adhesion to the final coating.

A closely sized, tough, medium density, virgin fused brown aluminum oxide abrasive. One of the hardest and toughest abrasives you can buy, Blastite is designed for the pressure blasting of materials of almost every type, including: glass, granite, marble, and ceramic and it is also used for the preparation of surfaces prior to painting or bonding; as well as for light de-burring, scale removal, and the generation of matte finishes.
A group graded, virgin brown aluminum oxide for use in blasting operations where size control is less critical.
A more closely graded, high purity fused white aluminum oxide that is composed of sharp, friable grains - specially treated for removal of iron. It is a more costly, premium material - for use where surface contamination is unacceptable.
An extremely hard, sharp grain that is more friable than aluminum oxide. Used for blasting extremely hard materials.
