Finishing Like a Pro with 320 Grit Sanding Discs for Ultra-Fine Smoothing

320 grit sanding discs are the final word in smoothness before applying your last coat of finish or between coats for a flawless result. They remove the tiniest imperfections without altering the shape of your workpiece. The 5-Inch 8-Hole Sanding Discs, Hook & Loop, Assorted Grit (50-Pack) include top-quality 320 grit discs ideal for woodworking, cabinetry, and fine finish work.

Why 320 Grit is the Final Touch

This grit creates an ultra-smooth surface, perfect for final pre-finish prep or for sanding between coats. It’s fine enough to remove tiny nibs, dust particles, or raised grain without dulling the finish.

Best Uses for 320 Grit

• Between Coats of Finish: Smooths the surface for the next coat to bond perfectly.
• Final Pre-Finish Pass: Leaves the surface silky-smooth before topcoat application.
• Polishing Bare Wood: For extremely fine woodworking projects.
• Detail Work: Ideal for trim, furniture edges, and delicate areas.

Tools & Setup

Step-by-Step: Using 320 Grit

1. Prep the Surface: Make sure it’s already been sanded with 220 grit or similar.
2. Attach the Disc: Align the 8 holes for proper dust collection.
3. Sand Gently: Apply minimal pressure to avoid burnishing the surface.
4. Short, Controlled Passes: Focus on consistency rather than speed.
5. Inspect Under Light: Look for uniform sheen and smoothness before finishing.

Pro Tips

• Use a clean disc to avoid introducing scratches at this stage.
• Vacuum the surface after sanding to prevent dust contamination in the finish.
• For between-coat sanding, wipe with a tack cloth before reapplying finish.

Common Mistakes

• Starting with 320 Grit: Inefficient for material removal—use finer stages only for finishing.
• Pressing Too Hard: Can close wood grain and reduce stain absorption.
• Skipping This Step Between Coats: Can lead to rough or uneven final finish.
