Smooth Results with 150, 360, and 1000 Grit Sandpaper

When your project calls for reliable surface prep, smooth refinement, and a fine finish, the sanding sequence of 150, 360, and 1000 grit sandpaper is an excellent option. This combination is versatile for woodworking, automotive detailing, and resin polishing.

Why This Sequence Works

150 grit provides the foundation by removing light imperfections and shaping surfaces. 360 grit bridges the gap, smoothing scratches and leaving surfaces ready for coating. Finally, 1000 grit produces a refined, satin-smooth polish that’s perfect for clear coats and resin finishes.

Tools You’ll Need

• Orbital sander or sanding block for 150 grit prep
• Sanding sponge or flexible pad for 360 grit refinement
• Foam pad with water spray bottle for 1000 grit wet sanding
• Vacuum and tack cloth

Step-by-Step Process

1. Surface prep. Start with 150 grit (25-pack) to remove scratches and smooth the base material.
2. Refinement. Move to 360 grit (50-pack) to erase sanding marks and create an even surface.
3. Final polish. Wet sand with 1000 grit (100-pack) for silky smooth, finish-ready results.
4. Clean carefully. Always vacuum and tack cloth between grit stages to avoid dust contamination.

Special Cases

In woodworking, 150 grit preps raw surfaces, 360 grit gets them finish-ready, and 1000 grit adds premium smoothness. In automotive refinishing, 150 grit helps shape fillers, 360 smooths primers, and 1000 polishes clear coats. Resin projects also benefit from 1000 grit for clarity and gloss.

Pro Tips

• Don’t jump from 150 straight to 1000—360 grit ensures smooth transitions.
• Wet sanding at 1000 grit provides the best finish and prevents clogging.
• Apply light pressure with finer grits to avoid streaks or uneven polishing.

Aftercare

• Apply protective finishes after sanding to maintain the surface quality.
• Buff 1000 grit finishes with compounds for added gloss.
• Store sandpapers flat and dry to extend their effectiveness.

FAQs

• Is 150 grit fine enough for finishing? It’s a prep grit—always follow with finer stages.
• Why use 360 grit? It’s ideal for smoothing and preparing surfaces for coatings.
• What’s 1000 grit best for? It creates refined, satin-smooth surfaces ready for polishing or sealing.

Watch & Learn

By sanding with 150, 360, and 1000 grit in sequence, you’ll achieve professional-quality results that move seamlessly from prep to polished finishing.
