Step-by-Step Sanding with 100, 240, and 2000 Grit Sandpaper

For projects that require a balance of shaping, smoothing, and high-end polishing, the grit sequence of 100, 240, and 2000 grit sandpaper is an excellent choice. This progression allows you to move from coarse prep to ultra-fine finishing with confidence.

Why This Sequence Works

100 grit removes rough surfaces, tool marks, or old coatings. 240 grit smooths and refines, creating a finish-ready surface. Finally, 2000 grit delivers an ultra-smooth polish that’s ideal for clear coats, resin, or fine woodworking.

Tools You’ll Need

• Orbital sander or sanding block for 100 grit prep
• Sanding sponge or pad for 240 grit refinement
• Foam pad with water spray bottle for 2000 grit wet sanding
• Vacuum and tack cloth

Step-by-Step Process

1. Initial sanding. Begin with 100 grit (25-pack) to strip coatings and smooth rough areas.
2. Intermediate smoothing. Switch to 240 grit (50-pack) to refine surfaces and prepare for finishing.
3. Final polish. Wet sand with 2000 grit (100-pack) for a polished, professional-grade surface.
4. Clean carefully. Vacuum and tack cloth after each grit stage to avoid dust buildup.

Special Cases

For woodworking, 240 grit is often enough before staining, but going to 2000 grit provides luxury smoothness. In automotive work, 100 grit shapes fillers, 240 smooths primers, and 2000 polishes clear coats. Resin projects also benefit from 2000 grit clarity before buffing.

Pro Tips

• Do not skip directly from 100 to 2000—240 grit is essential to remove coarse scratches.
• Always wet sand at 2000 grit for optimal clarity and reduced clogging.
• Use light, even strokes when sanding with finer grits.

Aftercare

• Apply finishes promptly after sanding to protect the surface.
• Buff 2000 grit finishes with compounds for a mirror-like appearance.
• Store sandpapers flat and dry to extend their lifespan.

FAQs

• Is 100 grit good for finishing? No, it’s for prep only—always refine with finer grits.
• Why use 240 grit? It’s the perfect balance grit for smoothing and prepping before stain or paint.
• What’s 2000 grit best for? It delivers ultra-fine polishing and high-gloss finishes.

Watch & Learn
