Interactivia Finishing Media Walnut Shell Media – 16 lb / 7.2 kg, 18-40 Grit for Tumbling, Blasting

Overview

Interactivia Finishing Media walnut shell media delivers a finely ground blend of walnut shells sized at 18-40 grit. Supplied as 16 lb (7.2 kg), this media is designed to pair with blasting equipment or vibratory tumblers, offering a versatile option for light surface refinement without harsh abrasion.

Compared with harder media, crushed walnut shells provide a controlled, gentler action that helps lift surface contaminants while helping preserve the underlying substrate. The result can be clean surfaces with a natural softness that works well as a prelude to finishing steps.

Key benefits

• Effective for removing paint, grease, and dirt while aiming to protect the substrate.
• Suitable for blasting or vibratory finishing, expanding your equipment options.
• Environmentally friendlier than many alternatives and 100% silica free.
• Compatible with a range of materials including glass, fiberglass, wood, plastic, stone, and soft metals.
• Crushed walnut shell offers a fine 18-40 grit texture for gentle abrasion.

Ideal applications

• Surface prep for glass or glass-like materials prior to coating or polishing.
• Light cleanup and polishing of wooden parts or plastic components.
• Soft metal finishing where deep gouges are undesirable.
• Grease and paint removal from stone or fiberglass substrates.

Usage tips and safety

For best results, test on a hidden area or sample piece before full-scale use. Follow appropriate blasting pressures and tumbling speeds, and observe safety guidelines for your equipment. After use, inspect components and separate debris if needed.
