How do I fix bubbles or dust in cured resin?

Finding small bubbles or dust in cured resin on your worktop can be disappointing, but these imperfections are usually easy to repair. Restoring a smooth, clear finish involves a few simple steps and the right materials.

Assessing and Preparing the Area

Before you start, examine the area closely in good lighting. Minor bubbles or patches of dust are most common on the final surface layer. Make sure the worktop is clean and dry. Lightly sand the affected patch with fine-grit sandpaper (try 400–800 grit), using care to feather the edges for a seamless result. Wipe away sanding residue completely before moving to the next stage.

Recoating for a Flawless Finish

After sanding, apply a fresh, thin layer of resin to the repaired spot. Products like Art Pro Clear Epoxy Resin are ideal for achieving a glossy, transparent result. Mix the resin as directed, then pour or brush on gently, allowing it to self-level. For larger repairs or decorative worktops, consider using a self-levelling resin kit for consistent coverage.

When This Matters

Addressing bubbles or dust is especially important on kitchen worktops or feature surfaces where clarity and hygiene are priorities. Prompt, careful repair ensures the worktop remains both attractive and easy to clean, preventing larger imperfections from developing over time.
