Repair Scratched Acrylic Panels with 220, 800, and 3000 Grit Wet Sanding

Acrylic panels on furniture, displays, or protective barriers can develop scratches that dull their appearance. Using a progressive sanding approach—220, 800, and 3000 grit—you can restore clarity without expensive replacement.

Why This Method Works

220 grit removes deep scratches and surface defects, 800 grit smooths the surface and removes coarse marks, and 3000 grit polishes the acrylic to a near-clear finish.

Tools & Materials

• Wet/dry sandpaper: 220 grit (50-pack), 800 grit (25-pack), 3000 grit (25-pack)
• Soft foam sanding pad
• Spray bottle with water + mild soap
• Microfiber cloths
• Masking tape

Recommended Grit Sequence

• 220 grit: Remove deep scratches and level the surface. (50-pack)
• 800 grit: Refine texture and erase coarse sanding marks. (25-pack)
• 3000 grit: Achieve high clarity before optional polish. (25-pack)

Step-by-Step Process

1. Prep the area. Clean the acrylic with mild soap and water, then dry. Mask surrounding areas if working in place.
2. Initial sanding. Wet sand with 220 grit sandpaper to remove deep marks. Keep surface wet to avoid heat buildup.
3. Intermediate smoothing. Switch to 800 grit sandpaper to refine the surface and remove visible lines.
4. Final finish. Lightly sand with 3000 grit sandpaper in circular motions for a smooth, clear surface.
5. Inspect & clean. Wipe down with a microfiber cloth. Optionally, apply acrylic polish for extra shine.

Special Considerations

Acrylic is softer than glass—always use light pressure to avoid creating deep gouges.

Pro Tips

• Sand in alternating directions with each grit for even results.
• Replace paper as soon as it loses cutting efficiency.
• Work slowly—rushing can leave visible imperfections.

Aftercare

• Clean with non-abrasive cloths and mild soap.
• Avoid ammonia-based cleaners to prevent clouding.

FAQs

• Can I skip 800 grit? No—skipping can leave coarse scratches visible.
• Does 3000 grit make it look like new? In most cases, yes—especially when followed by a polish.
• Will this work on polycarbonate? Yes—but polycarbonate is softer, so use lighter pressure.
