Before powder coating anything, it needs to be sandblasted. Sandblasting is one of the effective ways to reshape, strip or smoothen the surface of any foreign material. This is similar to sanding something down, but provides a more even surface, including corners and
Sandblasting is like high-octane sandpaper. A blasting setup typically consists of three distinct parts: the abrasive itself, the Air Compressor, and the blast nozzle. It uses compressed air to blow grit and sand toward objects to help remove oil, rust, and old paint. Blast grits range from walnut to factory steel drill bits. The shape and pattern of the blasting particles will vary depending on the size and material of the object being blasted.

After sandblasting, the resulting object should remain smooth and clean of any human or factory residue.
Sandblasting is the first step in the powder coating process because it ensures that the paint will adhere to a flat surface. Powder coating is usually applied immediately after sandblasting to prevent rust or other residue from reattaching to the object.
