Precision Finish Sequence: 150, 800, 2000, and 3000 Grit Sanding

For surfaces that demand both heavy correction and ultra-fine finishing, the 150 → 800 → 2000 → 3000 grit progression offers complete control. This method is excellent for restoring worn finishes, leveling imperfections, and achieving a mirror-like polish.

Why This Sequence Works

150 grit removes stubborn defects and levels the base. 800 grit smooths and evens the surface, 2000 grit removes fine haze, and 3000 grit perfects the surface for polishing.

Tools & Materials

• Orbital sander or hand sanding block
• Wet/dry sandpaper in 150, 800, 2000, and 3000 grit
• Spray bottle with water + drop of dish soap
• Microfiber cloths
• Fine polishing compound

Step-by-Step Sanding Process

1. Initial sanding. Begin with 150 grit to level imperfections and strip old finishes.
2. Intermediate smoothing. Move to 800 grit for a smoother, uniform surface.
3. Fine sanding. Use 2000 grit to remove fine haze and prepare for ultra-fine sanding.
4. Final sanding. Finish with 3000 grit for a satin finish ready for polishing.
5. Polish. Apply fine compound and buff to a high-gloss finish.

Special Cases

On delicate surfaces like instrument finishes, reduce pressure and always keep the surface wet to prevent damage.

Pro Tips

• Inspect thoroughly between grit changes to avoid trapping scratches.
• Replace clogged paper promptly for best cutting performance.
