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/Aluminum Oxide Grit

Image of Product. Front orientation. Abrasive Blasting Media.

A mixture of glass bead and aluminum oxide removes tough corrosion in applications where 100% aluminum oxide is too aggressive.

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