  • Glass and Ceramics: Medium to fine beads (70-140 mesh) work well for cleaning and finishing without causing surface damage.

  • Matte Finish: Coarser beads (40-70 mesh) are better for achieving a matte or satin finish.

  • Peening: For surface strengthening and stress relief, finer beads (100-200 mesh) are typically used.

  • Mesh size refers to the number of openings per inch in a screen. A higher mesh number indicates finer beads.

  • Grit size is another way to measure bead size, often used interchangeably with mesh size.

  • Higher blasting pressures can handle coarser beads, while lower pressures are better suited for finer beads.

  • Ensure your equipment can accommodate the bead size you choose.

  • Use medium-sized beads (60-100 mesh) for effective rust and paint removal without damaging the underlying material.

  • For preparing surfaces for painting or coating, medium to fine beads (70-140 mesh) provide a clean, smooth surface.

  • Finer beads (100-200 mesh) are ideal for polishing and finishing applications, providing a smooth, reflective surface.

  • Use finer beads (100-200 mesh) for peening applications to relieve surface stress and improve fatigue resistance.

  • Conduct trial runs with different bead sizes to determine the best fit for your specific project.

  • Based on the trial results, adjust the bead size, blasting pressure, and nozzle size to optimize performance.
