Professional Sanding with 60, 400, and 1000 Grit Sandpaper

For projects that require strong material removal, precise smoothing, and refined polishing, the sanding sequence of 60, 400, and 1000 grit sandpaper is highly effective. This trio works across woodworking, resin, and automotive surfaces to achieve professional results.

Why This Sequence Works

60 grit aggressively removes material, paint, or heavy imperfections. 400 grit bridges the gap, refining surfaces and preparing them for finishes. Finally, 1000 grit provides silky smoothness and a polished look ready for sealing or buffing.

Tools You’ll Need

• Orbital or drum sander for 60 grit heavy sanding
• Sanding block or sponge for 400 grit refinement
• Foam pad with water spray bottle for 1000 grit wet sanding
• Vacuum and tack cloth

Step-by-Step Process

1. Coarse sanding. Begin with 60 grit (25-pack) to strip paint, flatten surfaces, or remove deep scratches.
2. Refinement. Switch to 400 grit (50-pack) to erase coarse marks and prepare for coatings.
3. Final polish. Wet sand with 1000 grit (100-pack) for a smooth, professional-grade surface.
4. Clean carefully. Always vacuum and tack cloth after each sanding stage to avoid residue.

Special Cases

In woodworking, 60 grit is used only for shaping or stripping, while 400 grit prepares for stain and 1000 grit refines the finish. In auto refinishing, 60 grit shapes filler, 400 grit smooths primer, and 1000 grit polishes clear coats. Resin projects also benefit from the clarity that 1000 grit provides.

Pro Tips

• Use 60 grit cautiously—it’s very aggressive and should always be followed with finer sanding.
• Always wet sand at 1000 grit for maximum smoothness and reduced clogging.
• Work gradually—each grit sets the foundation for the next stage.

Aftercare

• Seal or finish surfaces immediately after sanding to preserve smoothness.
• Buff 1000 grit finishes with compounds for added shine.
• Keep sandpapers flat and dry to ensure effectiveness.

FAQs

• Is 60 grit safe for furniture? Only for stripping or heavy leveling—always refine with finer grits.
• Why use 400 grit? It’s a versatile grit for smoothing and between-coat sanding.
• What’s 1000 grit best for? It produces smooth, polished surfaces ready for coatings or buffing.
