INTERACTIVIA Walnut Shell Media 8 lb (18-40 Grit) for Blasting, Tumbling & Polishing

Refined Walnut Shell Media for Versatile Cleaning and Finishing

Meet INTERACTIVIA 8 lb of finely crushed walnut shell media, sized 18-40 grit, designed for abrasive blasting and vibratory tumbling. This media blends a granular texture with a durable profile, offering a balanced approach to cleaning and light finishing without compromising the substrate beneath. It’s a great fit for operators who want a gentle yet effective option for surface conditioning.

In blasting applications, walnut shell media excels at removing paint, grease, and embedded soils while preserving underlying materials. The same material also shines in vibratory tumblers, delivering a smooth, refined edge on varied surfaces. The 18-40 grit range is versatile enough for deburring, soft polishing, and preparing surfaces for subsequent finishes, making it a practical choice for workshop setups that handle multiple part families.

Key benefits you may notice

• Surface-friendly cleaning resumes a clean look without aggressive abrasion on glass, fiberglass, wood, plastic, stone, or soft metals.
• Efficient paint and grime removal while keeping substrate integrity intact—helping you achieve cleaner parts with fewer passes.
• Compatible with blasting and tumbling, enabling flexible workflows in mixed-processing environments.
• Eco-conscious choice as an environmentally friendly, silica-free option that aligns with responsible manufacturing practices.

Allergy awareness is important: this media contains walnuts. Use appropriate safety measures, work in a well-ventilated area, and follow standard handling guidelines to minimize exposure or contact with skin and eyes.

Real-life use scenarios

• Glassware restoration cleans residues and returns a clearer sheen without etched marks.
• Wood components benefit from gentle deburring and a more uniform surface ready for finishing.
• Plastic parts receive effective grease removal without degrading the resin structure.
• Stone and soft metals surfaces regain a cleaner, more even look without harsh scraping.

To maximize results, pair this media with appropriate blasting parameters or tumbling settings, and always follow your equipment manufacturer’s guidelines. Rinse and inspect parts after processing, then proceed with any planned coatings or sealants for best overall appearance.
