Abrasive Blasting Media for Delicate Materials

Remove paint, coatings, and rust from delicate materials. Softer than other abrasive blasting media, this media cleans away contaminants without scratching or marring the underlying surface. It is a good choice for finishing soft metals, plastics, wood, or sensitive equipment.

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.

Walnut Shell

Soft-grit shells clean, polish, and debur soft metals, fiberglass, plastic, wood, and stone.

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