How to Restore Dull or Scratched Resin Surfaces

Q: Step-by-Step Restoration: Sanding and Re-coating

Light Sanding: Begin by gently sanding the affected area using fine-grit sandpaper (often 600-grit or higher). Sand in a circular motion to even out scratches and dullness. Clean Thoroughly: Remove all dust with a soft, damp cloth and let the surface dry completely. Re-apply Resin: Prepare a thin layer of clear resin, such as Art Pro Clear Epoxy Resin , and apply it evenly across the sanded surface. This self-levelling layer will restore the high-gloss, transparent finish. Allow to Cure: Let the new coat set undisturbed according to the product instructions, usually 12–24 hours.

What should I do if the new resin surface looks dull or scratched?

Discovering your newly finished resin surface has lost its shine or shows scratches can be frustrating. Fortunately, restoring gloss and smoothness to resin sinks and worktops is a straightforward process with the right approach.

Why Resin Surfaces Become Dull or Scratched

Even carefully finished resin surfaces can lose their sheen over time or become marked with scratches, especially in high-use areas like sinks and countertops. Common causes include abrasive cleaning tools, grit, or everyday wear and tear. While this is normal, it can be easily remedied with some basic refinishing steps.
