Why Is My Polished Resin Jewellery Still Cloudy?

← Back to How do you polish resin jewellery?

If your resin jewellery looks cloudy after polishing, you’re not alone. This common issue usually points to a missed step in the sanding or polishing process, but the good news is it can usually be resolved with a little extra care.

Common Causes of Cloudy Resin Jewellery

Cloudy or dull finishes on resin pieces almost always stem from incomplete sanding. Tiny scratches left by coarse grit papers scatter the light, making the resin appear hazy even after you’ve polished it. Alternatively, remaining residue from previous polishing stages or using the wrong tools can also contribute to a lacklustre result.

Effective Steps to Achieve a Clear Gloss

To fix cloudiness, work back through the sanding process. Start with a fine grit, gradually moving up to 2000–4000 grit pads—like the “Ebonite Abralon” Sanding Pads—to remove leftover scratches. Rinse the piece well between sanding stages to avoid contaminating finer grits. For polishing, specialised systems such as “Epoxy Polish” – Epoxy Resin Polishing System are designed to bring out maximum clarity and gloss. Ensure you use a rotary polisher or a manual pad holder for consistent results rather than relying on a basic cloth.

When This Matters Most

If your jewellery is meant to be a centrepiece, gift, or product for sale, a cloudy finish will undermine its appeal. Taking the time to properly sand and polish is worth it when high clarity is the goal, especially for transparent or light-coloured designs where imperfections show easily.
