Abrasive Blasting Media

Remove paint, coatings, and rust or add texture to surfaces. This media is suitable for use on a wide variety of surface materials.

Our abrasive blasting materials are sorted from least to most aggressive. The more aggressive the media, the more material it removes from your surface.

Both particle mesh size and grit measure the size of the abrasive particles. The higher the number, the finer the particles are.

Glass Bead

Image of Product. Front orientation. Abrasive Blasting Media.

Round beads remove carbon and surface residue for a smooth, bright finish. It is inert and leaves no residue. Peens aluminum and plastic.

Low Reusability—Effective for a handful of cycles under normal blasting conditions.

Steel Shot

Generates a high-impact force to clean and peen heavy forgings and remove heat-treated scale on steel and other cast metals.

High Reusability—Effective for hundreds of cycles under normal blasting conditions.

Stainless Steel Shot

Outlasts glass bead and Black Beauty grit by a ratio of 1,000 to 1. It descales nonferrous metals and peens aluminum and plastic. Not recommended for removing paint from aluminum and plastic.

Very High Reusability—Effective for thousands of cycles under normal blasting conditions.
