Ultimate Sanding Sequence: 600, 1200, 2000, and 3000 Grit for a Showroom Shine

When aiming for a deep, high-gloss finish, the key is moving through the right progression of grits. Starting at 600 grit and ending with 3000 grit ensures you remove imperfections at each stage while preparing the surface for a perfect polish.

Why This Sequence Works

Each grit in the 600 → 1200 → 2000 → 3000 progression serves a purpose: coarse enough to level flaws early on, fine enough to leave the surface flawless for final polishing. Skipping a step risks leaving scratches that will show through the finish.

Tools & Materials

• Orbital sander or sanding block with soft interface pad
• Wet/dry sandpaper sheets in 600, 1200, 2000, and 3000 grit

Step-by-Step Sanding Process

1. Prep the surface. Clean and dry before starting.
2. Initial sanding. Use 600 grit to level out defects.
3. Intermediate sanding. Move to 1200 grit to refine scratches.
4. Fine sanding. Use 2000 grit for a silky smooth surface.
5. Ultra-fine finish. Lightly go over with 3000 grit to prep for polishing.
6. Polish. Apply a fine compound and buff to a mirror shine.

Special Cases

For delicate finishes, reduce pressure and keep the surface wet to avoid overheating.
