Walnut Shell Grit
Walnut Shell Grit is a versatile, organic media. It is an angular media that is soft and sensitive to many surfaces. Walnut Shell Grit is an economical, biodegradable alternative for sensitive operations that require a moderately aggressive media.
Walnut Shell Grit
Walnut shell grit is the hard fibrous product made from ground or crushed walnut shells. When used as a blasting media, walnut shell grit is extremely durable, angular and multi-faceted, yet is considered a ‘soft abrasive’. Walnut shell blasting grit is an excellent replacement for sand (free silica) to avoid inhalation health concerns.
Cleaning by walnut shell blasting is particularly effective where the surface of the substrate under its coat of paint, dirt, grease, scale, carbon, etc. should remain unchanged or otherwise unimpaired. Walnut shell grit can be used as a soft aggregate in removing foreign matter or coatings from surfaces without etching, scratching, or marring cleaned areas.
When used with the proper walnut shell blasting equipment, common blast cleaning applications include stripping auto and truck panels, cleaning delicate molds, jewelry polishing, armatures and electric motors prior to rewinding, deflashing plastics and watch polishing. When used as a blast cleaning media, walnut shell grit removes paint, flash, burrs, and other flaws in plastic and rubber molding, aluminum and zinc die-casting. Walnut shell can replace sand in paint removal, graffiti removal, and general cleaning in restoration of buildings, bridges, and outdoor statuaries. Walnut shell is also used to clean auto and aircraft engines and steam turbines.

Walnut Shell Grit media offers several benefits. It is environmentally friendly, non-toxic, and does not pose any health or environmental hazards. It preserves gel coats, base, and primer while removing the topcoats of paint. Walnut Shell Grit can remove the contaminants from surfaces without scratching or pitting underlying material.
The Walnut shell media is also durable, reusable, and biodegradable and reduces the cycle time of finishing operations. It preserves micro finishes and prevents the issue of silicosis as it is silica-free.
Walnut Grit is softer than sand and maintains the integrity of the underlying structure when used properly. Great for removing graffiti, transmissions, and cleaning engines, soft metals, prepping metal for paint, or restoring historical items. Lesser damage to the substrate means the job gets completed quicker — a great non-toxic solution to your Blasting needs.
