Smoothing Plastic Surfaces with eQualle Sandpaper Sheets (220, 400, 800, 1200 Grits)

Sanding plastic requires a careful approach to avoid scratches, melting, or uneven finishes. Whether you’re repairing a plastic part, prepping for paint, or restoring clarity, eQualle Sandpaper Sheets (9 x 11 inches) provide consistent performance for smooth, professional results.

Why Sanding Plastic is Different

Unlike wood or metal, plastic can overheat and deform if sanded too aggressively. Choosing the right grits and sanding technique ensures you remove imperfections while maintaining the material’s integrity.

Essential Tools

• eQualle Sandpaper Sheets (9x11 in)
• Sanding block or soft foam pad
• Spray bottle with water (for wet sanding)
• Microfiber cloths
• Plastic polish or primer

Recommended Grit Sequence

• 220 Grit (25-pack) — For initial smoothing and scratch removal.
• 400 Grit (100-pack) — For refining surface and prepping for primer.
• 800 Grit (25-pack) — For fine sanding and restoring clarity.
• 1200 Grit (25-pack) — For ultra-smooth finishing before polish.

Step-by-Step Process

1. Clean the plastic. Wipe down the surface to remove dirt and oils.
2. Start with 220 grit. Sand lightly to remove scratches or uneven spots. Keep pressure minimal.
3. Refine with 400 grit. Smooth out the surface, preparing it for primer or paint.
4. Polish with 800 grit. Wet sand to reduce haze and bring back clarity.
5. Final finish with 1200 grit. Wet sand gently to create a smooth, polished base ready for polishing compound.
6. Buff and protect. Apply plastic polish or clear coat for a durable finish.

Special Cases

For clear plastics like acrylic or polycarbonate, always use wet sanding for grits above 400 to prevent scratches and maintain transparency.

Pro Tips

• Keep the surface wet while sanding to avoid heat buildup.
• Use circular motions for small areas and straight strokes for larger surfaces.
• Work gradually—rushing can cause irreversible scratches.
• Switch to a fresh sheet when sanding efficiency decreases.

Aftercare

• Wipe with microfiber cloths to prevent micro-scratches.
• Avoid abrasive cleaners—use mild soap and water.
• Apply protective coating or polish every few months for long-lasting clarity.

FAQs

• Can I sand all types of plastic? Yes, but softer plastics require extra care and finer grits.
• Is dry sanding okay for plastic? Only for coarse grits like 220. Use wet sanding for finer grits to prevent heat damage.
• Can sanding remove deep cracks? No, sanding only smooths the surface—cracks may require repair or replacement.
