Step-by-Step Guide: How to Polish Epoxy Resin for a Glass-Like Finish
Polishing epoxy resin isn’t hard, but you need to follow a few steps for the best results. Here’s how to get that perfect shine:
What You’ll Need
- Polishing compound (made for epoxy resin)
- Microfiber cloths or soft pads
- Sandpaper (grits 600 to 3000)
- Water spray bottle
- Buffing machine (optional)
Prepping Your Resin Surface
- Clean your resin piece with warm soapy water and let it dry.
- If you see bumps or uneven spots, wet-sand them with 600-grit sandpaper, working up to 2000 or 3000 grit for a smooth finish.
-
-
Always sand in a circular motion.
-
Keep the surface wet to avoid scratches.
-
Sanding vs. Polishing
- Sanding removes deep marks and levels the surface.
- Polishing comes after, using a compound to smooth and shine the resin.
- Don’t skip sanding if your resin feels rough or looks cloudy. If your surface is already smooth, you can go straight to polishing.
How to Polish
- Apply a small amount of polishing compound to your cloth or pad.
- Rub the polish onto the resin in a circular motion, covering the whole area.
- Use gentle pressure and keep working until you see the shine come through.
- For bigger projects, use a buffing machine on low speed.
- Wipe off any extra polish with a clean microfiber cloth.
Pro Tips for Getting a Mirror Finish on Epoxy Resin
Want that “wow” factor? Here’s how to take your shine up a notch:
- ✅ Always sand up to 2000 or 3000 grit before polishing for the smoothest results.

- ✅ Don’t rush! Let your resin cure fully before sanding or polishing.
- ✅ If your resin looks cloudy after polishing, wipe it with a damp cloth and polish again.
