Masking for Sandblasting & Shot Peening

Sandblasting and shot peening are aggressive surface preparation processes that require highly resilient masking materials. The primary challenge is not heat, but extreme abrasion. Masking must absorb the impact of abrasive media (sand, grit, glass beads, or steel shot) without degrading, tearing, or lifting from the part surface.

At Masking Supply, we supply heavy-duty masking tapes, thick silicone plugs, caps, and custom die-cut shapes engineered specifically to withstand abrasive blasting. Our products protect critical surfaces, threads, and delicate features while maintaining sharp, precise boundaries.

Masking Products for Sandblasting

  • Green polyester masking tape for powder coating and anodizing, temperature-resistant up to 200°C

    Heavy-Duty Masking Tape

    Thick, abrasion-resistant backing designed to absorb the impact of abrasive media without tearing or lifting.

    Browse Masking Tapes 
  • Polyimide masking tape for powder coating, PCB manufacturing, and electronics, temperature-resistant up to 260°C

    Glass Cloth Masking Tape

    Woven glass fibre backing provides excellent resistance to particle impact. Often used in high-pressure blasting applications.

    Browse Glass Cloth Tapes 
  • Dual-flanged silicone pull plug for masking weld nuts and through holes, temperature-resistant up to 250°C

    Silicone Masking Plugs

    Protect threaded holes, blind bores, and recesses. The thick silicone material absorbs abrasive impact without degrading.
