Epoxy resin jewelry is popular for its versatility, durability, and unique aesthetics. Sometimes we are faced with minor imperfections, but with a little elbow grease we can remove them and return the epoxy resin back to its beautiful high-gloss shine. However, to achieve that perfect high-gloss finish, it is essential to follow a proper polishing process. In this article, we will guide you through the steps of sanding and polishing epoxy resin jewelry to help you achieve a stunning, professional-looking finish.
Materials and Tools for Polishing Epoxy Resin
Before you begin, make sure you have the following materials and tools on hand:
- Epoxy resin jewelry
- Wet/dry sandpaper in various grits (ranging from 400 to 3000)
- A bowl or container of water
- Polishing compound
- Buffing wheel or soft cloth
- Safety goggles and a dust mask
Step 1: Sanding the Epoxy Resin to a Smooth Surface
Begin by donning your safety goggles and dust mask to protect your eyes and lungs from any resin dust particles.
Start with the lowest grit sandpaper (around 400) and gently sand the surface of your epoxy resin jewelry. Apply even pressure and use circular motions to remove any imperfections, uneven surfaces, or bubbles.
Frequently dip your sandpaper in the water to clean it and keep the sanding process smooth. This wet-sanding technique also helps prevent excessive resin dust.
Once the surface feels smooth and even, move on to the next grit sandpaper (600 to 800 grit) and repeat the process. Make sure to sand the entire surface of the piece, paying close attention to corners and edges.
Step 2: Removing Swirl Marks with High Grit Sandpaper
As you progress through the sanding process, you will notice fine swirl marks left by the previous grits. To remove these, continue working your way up to higher grit sandpapers (1000 to 3000). Be sure that you remove the previous grits swirl marks the best that you can or you may have to return to that grit.
Remember to use circular motions and apply even pressure when sanding. Always keep the sandpaper wet to ensure a smoother finish.
Check the surface periodically to ensure the swirl marks are disappearing. As you use higher grit sandpapers, the surface should begin to develop a semi-gloss sheen.
Step 3: Applying Polishing Compound to the Epoxy Resin
Once you have sanded your epoxy resin jewelry with the highest grit sandpaper, thoroughly rinse and dry the piece to remove any remaining grit or dust.
Apply a small amount of polishing compound to a clean buffing wheel or soft cloth. Make sure to read the manufacturer's instructions for the recommended application method and quantity.
Gently rub the polishing compound onto the surface of the epoxy resin jewelry using circular motions. Ensure that you cover the entire piece, including any hard-to-reach areas.
Step 4: Buffing Epoxy to a High-Gloss Finish
Using the buffing wheel or soft cloth, buff the epoxy resin jewelry in a circular motion while applying light pressure.
Continue buffing until the surface reaches the desired high-gloss finish. If necessary, apply more polishing compound and repeat the buffing process.
When you have achieved the desired shine, use a clean, soft cloth to remove any excess polishing compound from the jewelry.

Polishing epoxy resin jewelry requires patience, attention to detail, and the right tools. By following these steps and starting with a smooth, well-sanded surface, you can achieve a stunning high-gloss finish that will make your epoxy resin jewelry truly stand out. Happy polishing!
