Professional Applications

Why Choose Grade 320?

Grade 320 grit sits in the ultra-fine category, making it the optimal choice for final surface preparation before painting, coating, or polishing. This grit removes fine scratches left by coarser grades (such as 240 or 180) while creating a smooth, uniform surface that accepts finishes evenly.

In automotive refinishing, 320 grit is the industry standard for feathering paint edges, sanding primer, and preparing surfaces for base coat application. For woodworkers, it provides the final smoothing step before staining or clear coating, ensuring a professional, glass-smooth finish.

What's Included

• 10 × 50mm (2") Grade 320 sandpaper discs with hook & loop backing
• Compatible with standard 50mm backing pads (backing pad sold separately)

Usage Tips for Best Results

1. Progressive Grits: Always work through progressive grit stages (e.g., 120 → 240 → 320) for optimal surface finish
2. Light Pressure: Let the abrasive do the work – excessive pressure reduces disc life and can create uneven surfaces
3. Keep Moving: Maintain constant motion to avoid creating low spots or burn marks on the workpiece
4. Clean Surface: Remove dust between grit changes to prevent coarser particles from scratching the surface
5. Replace When Worn: Change discs when cutting performance diminishes to maintain consistent finish quality
