How can I remove air bubbles from cured resin?

It’s not uncommon to find pesky air bubbles trapped in resin after it’s cured. Whether you’re creating jewellery, art, or crafts, this guide covers how to tackle surface and internal bubbles for a flawless finish.

Surface Bubbles: Use Isopropyl Alcohol and Polishing

For small surface bubbles, gently mist the resin with isopropyl alcohol and allow it to evaporate completely. This can help reduce the appearance of bubbles freshly after curing. For bubbles that remain after this, use fine-grit sandpaper to carefully sand down the affected area. Start with a higher grit for gentle removal, then move to finer grades for smoothing. Complete the process by polishing to return clarity and gloss.

Dealing with Deeper Bubbles

When bubbles are located deeper within the resin, especially in thicker castings or detailed moulds, sanding alone may not be enough. For creative projects where clarity is crucial, products like Liquidissima epoxy resin can help minimise bubbles during casting due to its low viscosity and self-levelling formula. However, if bubbles do appear after curing, sometimes recasting a thin new layer over the problematic area offers a practical solution.
