Polishing Resin Projects with eQualle Sandpaper Sheets (180, 400, 800, 1500 Grits)

Resin projects like coasters, jewelry, and tabletops often cure with uneven surfaces, bubbles, or dull finishes. Sanding with the right grit sequence transforms these imperfections into smooth, glossy results. With eQualle Sandpaper Sheets (9 x 11 inches), you can achieve a professional polish on resin crafts at home.

Why Sanding Matters for Resin

Resin hardens into a durable material but often needs refinement. Sanding levels surfaces, removes casting marks, and preps for buffing or polishing compounds to achieve a crystal-clear shine.

Essential Tools

• eQualle Sandpaper Sheets (9x11 in)
• Sanding block or orbital sander
• Spray bottle with water (for wet sanding)
• Microfiber cloths
• Polishing compound
• Buffing wheel or pad (optional)

Recommended Grit Sequence

• 180 Grit (25-pack) — For leveling uneven surfaces and removing casting marks.
• 400 Grit (100-pack) — For refining and smoothing after coarse sanding.
• 800 Grit (25-pack) — For fine wet sanding to restore clarity.
• 1500 Grit (50-pack) — For ultra-fine sanding before polishing compounds.

Step-by-Step Process

1. Clean the resin. Wash the surface to remove dust or oils before sanding.
2. Level with 180 grit. Sand down uneven spots or sharp edges.
3. Smooth with 400 grit. Transition the surface to a refined matte look.
4. Polish with 800 grit. Wet sand to restore partial clarity and reduce scratches.
5. Finish with 1500 grit. Wet sand for a smooth, ready-to-polish surface.
6. Buff and shine. Apply polishing compound with a cloth or buffing wheel for a crystal-clear finish.

Special Cases

For deep bubbles or inclusions, sanding may require extra time at 180 grit. For small jewelry, cut eQualle sheets into narrow strips to fit detailed areas.

Pro Tips

• Always wet sand resin to avoid overheating and clogging sandpaper.
• Work in circular motions for even results.
• Check progress frequently under good lighting.
• Use fresh sheets often—resin can quickly wear down sandpaper.

Aftercare

• Clean resin projects with mild soap and water.
• Avoid harsh abrasives that dull the finish.
• Rebuff with polishing compound if the surface becomes hazy over time.

FAQs

• Can I stop sanding at 800 grit? Yes, but for a glass-like shine, continue to 1500 grit and polish.
• Do I need polishing compound after sanding? Yes, sanding preps the surface, but polishing compound achieves full clarity.
• Can I use power sanders on resin? Yes, but use light pressure and keep surfaces wet to prevent melting.
