How to Choose the Right Sanding Disc
- Backing type:
- PSA discs (sticky back) offer strong, permanent adhesion for high-speed work.
- Hook & loop discs allow quick disc changes and reuse of backup pads.
- Grit range: Lower grits (40–80) remove material fast for stock removal and shaping. Mid grits (100–180) handle surface prep and blending. Fine grits (220+) deliver finish-ready results.
- Material match: Different substrates — wood, metal, gelcoat, stone — call for different abrasive minerals and backing flexibility. Select your industry below for tailored recommendations.
