Noticing a lacklustre finish or dull spots on your resin creation? This typically means the surface has developed countless micro-scratches—tiny abrasions that disperse light and reduce gloss. Understanding how these form and how to remove them ensures your work gets the shine it deserves.
Why Micro-Scratches Cause Dullness
Resin surfaces, though hard, are vulnerable to fine abrasions from cleaning, sanding, or general use. These minuscule scratches scatter light unevenly, resulting in a surface that looks cloudy or faded instead of glossy. Even with careful handling, micro-scratches accumulate over time, taking the shine off your finished project.
How to Restore Gloss: The Stepwise Polishing Approach
The most effective way to remove dullness is to smooth out the surface so that it can reflect light evenly again. Begin with a high-grit sanding pad such as the “Ebonite Abralon” Sanding Pads, gradually working your way from coarser to finer grits. This levels any imperfections and prepares the resin for final polishing. After sanding, apply a specialist polishing cream like “Epoxy Polish” – Epoxy Resin Polishing System using a suitable pad or sponge. Circular motions—either by hand or with a polishing machine—help achieve a mirror-like finish. Finishing touches are best achieved with a soft, purpose-made polishing sponge, which brings back clarity and gloss.
When This Matters Most
Restoring shine is especially critical for display-quality items, jewellery, and table tops, where the visual impact of perfect gloss is essential. If your resin piece is for functional or aesthetic display, addressing micro-scratches will keep it looking its best.
