How to Polish Epoxy Resin for a Glossy Finish – Simple Step-by-Step Guide

Want your epoxy projects to shine like glass? Polishing is the final (and most satisfying) step to bring out the full beauty of your resin creations. Whether you're working on a lamp, tabletop, or keycap, this guide will help you achieve a crystal-clear, glossy finish with ease.

🧼 Step 1: Clean the Surface

Start by wiping the resin surface clean. Use a microfiber cloth to remove dust, fingerprints, or oils before polishing.

🧼 Step 2: Sand If Needed

If the surface has scratches or feels uneven, gently sand it using fine-grit sandpaper (starting from 800 to 2000 grit). Always sand wet to avoid heat or dust buildup.

✨ Step 3: Apply Polishing Compound

Use a small amount of plastic or resin polishing compound. Apply it in circular motions using a soft cloth or foam pad. A slow, steady buff is all you need to bring out the shine.

🔁 Step 4: Buff and Repeat

Wipe off excess polish and repeat the buffing process until you achieve the desired gloss. The more you polish, the deeper the shine.

💡 Bonus Tip: DIY Polish Hack

In a pinch, toothpaste (non-gel type) can act as a mild polishing compound—perfect for small resin items like keycaps or pendants.

Final Thoughts

Polishing epoxy doesn’t need fancy tools—just patience and the right technique. Whether you're creating resin lamps or custom décor, a smooth, glossy surface makes your work truly stand out.
