Product Details
16 mesh garnet sand sits between ultra-coarse 12 mesh and medium grades, formulated to deliver balanced cutting force and controlled anchor profile for heavy industrial surface preparation. This natural almandine garnet is refined through rigorous gravity separation, magnetic purification and tiered screening to narrow particle distribution, avoiding oversized fragments that cause uneven surface texture.
Unlike the more aggressive 12 mesh garnet, this 16 mesh variant removes heavy corrosion, thick coal-tar epoxy and aged heavy-duty coatings while generating a predictable, uniform deep anchor profile ideal for high-performance protective coatings, thermal spray and zinc-rich primer systems. It consistently meets ISO 8501-1 Sa 3 near-white blast cleaning standard, making it a trusted option for projects with strict coating adhesion requirements. The garnet carries low soluble silica and moderate dust output, suitable for both open-air blasting sites and semi-enclosed blast yards with ventilation systems.
Key Features:
Balanced cutting power: removes heavy contaminants without creating overly deep, irregular pitting
Tight particle grading for stable, repeatable surface anchor profile
Mohs hardness 7.5-8.0, robust grain toughness with good recyclability
Low free silica content to reduce respiratory hazards for blasting crews
Matches specification requirements for high-build protective coating systems
Consistent batch quality across bulk shipments for large-site blasting contracts
