eQualle Sandpaper Sheets for Resin Projects (320–3000 Grit Guide)

Resin projects—from jewelry to tabletops—look their best when polished to a crystal-clear shine. Achieving that smooth, glossy surface requires sanding with the right grit progression. eQualle 9x11 inch Wet/Dry Sandpaper Sheets make it easy to refine resin surfaces from rough shaping to mirror-like clarity.

Why Sanding Resin is Important

Resin hardens with an uneven surface, bubbles, or rough edges. Sanding removes imperfections layer by layer. Using progressively finer grits prepares the resin for polishing compounds and ensures a flawless finish.

Tools You’ll Need

• Sanding block or foam pad
• Spray bottle with water
• Microfiber cloths
• Polishing compound
• eQualle 9x11 in Wet/Dry Sandpaper Sheets

Best Sandpaper Grits for Resin

• 320 Grit (100-pack) — Levels uneven surfaces and removes drips.
• 600 Grit (25-pack) — Smooths resin after initial shaping.
• 1500 Grit (50-pack) — Refines the surface for a near-polished look.
• 3000 Grit (50-pack) — Final sanding for high-gloss clarity before polishing.

Step-by-Step: Sanding Resin Projects

1. Clean the piece. Wash resin thoroughly to remove dust or mold release agents.
2. Start with 320 grit. Wet sand to remove uneven surfaces, drips, or casting marks.
3. Move to 600 grit. Smooth the surface while keeping it wet to prevent clogging.
4. Switch to 1500 grit. Refine the finish for a silky, smooth texture.
5. Finish with 3000 grit. Ultra-fine sanding prepares the resin for polishing compounds.
6. Polish. Apply resin polishing compound with a microfiber cloth for a glass-like shine.

Special Cases

For small resin jewelry pieces, hand sanding works best. For large epoxy tables, use an orbital sander with wet sanding pads to save time.

Pro Tips

• Always sand resin wet to reduce heat and clogging.
• Sand in alternating directions with each grit for even coverage.
• Polish immediately after 3000 grit for best results.

Aftercare

• Clean resin items with mild soap and water.
• Avoid abrasive cleaners that dull the finish.
• Re-polish as needed to maintain clarity.

FAQs

• Do I need to sand all resin projects? Yes, unless you used a high-gloss mold. Most castings require sanding and polishing.
• Can I skip directly to 1500 grit? Not recommended. Skipping grits leaves visible scratches.
• Is 3000 grit enough for final polishing? Yes, but using a polishing compound after 3000 grit gives the best clarity.
