Why 80 Grit is Essential

Its coarse abrasive particles cut fast, making it the ideal starting point for surfaces that need heavy stock removal. Whether refinishing old furniture or prepping rusty metal, 80 grit handles the toughest jobs.

Best Uses for 80 Grit

• Stripping Old Finishes: Removes thick paint, varnish, or lacquer quickly.
• Rust Removal: Cleans corroded metal before treatment.

• Rough Shaping: Ideal for initial contouring of wood or filler.

Step-by-Step: Using 80 Grit

1. Secure the Workpiece: Make sure it’s stable to avoid shifting.
2. Attach the Disc: Align the 8-hole pattern to maximize dust extraction.
3. Sand with Steady Motion: Avoid lingering in one spot to prevent gouging.
4. Check Progress Often: Stop once the material is removed.
5. Transition to 120 Grit: Smooth the surface after heavy removal.

Pro Tips

Common Mistakes

• Using for Finish Sanding: Too coarse for pre-finish prep.

FAQs

• Can I use 80 grit on softwoods? Yes, but avoid over-sanding to prevent tear-out.
