Walnut Shell Granulate

Gentle organic blasting media for delicate surfaces

Walnut shell granulate is an extremely soft, organic reusable blasting media made from crushed, cleaned and screened walnut shells. Due to its low hardness, it is primarily used for surface applications where the base material must be protected and material loss should be avoided.

This natural abrasive is made from 100% renewable raw materials and is a particularly environmentally friendly choice for gentle dry blasting, cleaning and surface treatment.

Typical applications

Gentle cleaning of sensitive surfaces
Dry blasting without significant removal of the base material
Removing deposits, coatings or residues from delicate components
Surface preparation where metallic contamination must be avoided
Reusable blasting processes with organic abrasive media
