Norton Silicon Carbide Q425 80 Grit Screen

- 100% Silicon Carbide Grain – Sharp & Aggressive Cut – Sharp P-graded 100% silicon carbide grain delivers an aggressive cutting action that easily cuts into even the hardest floor surfaces — far more cut efficiency than aluminum oxide, ideal for hardwoods, concrete prep, and finish removal.

- 80 Grit – Medium for Balanced Cut & Finish – 80 grit delivers a medium cut that balances aggression with surface refinement — the workhorse grit for general concrete surface profiling before coating application, between-coat abrading on hardwood, and intermediate finish removal.

- Open-Weave Polyester Screen – Resists Loading – Open-weave polyester screen backing offers extreme resistance to loading and clogging during heavy work — debris falls through the screen rather than packing into the grit, extending usable life dramatically compared to paper or cloth-backed discs.

- Waterproof, Reversible & Reusable – Both sides of the screen can be used and the disc is fully waterproof — rinse, dry, and reuse until completely worn out. Dramatically reduces consumable costs versus single-use abrasive discs.

- Versatile for Concrete & Wood Floors – Pairs with floor buffers, swing machines, and grinders for use on concrete (substrate prep, profiling, coating prep) and medium-to-hard wood floors (finish removal, between-coat abrasion). Always use with a screen driver pad to prevent slippage and maximize performance.
