How to Prevent Bubbles in Resin with Flowers

If you’re looking to preserve the beauty of flowers in resin, achieving a flawless, bubble-free finish makes all the difference. Here are some proven methods to help you avoid unwanted bubbles when embedding botanical elements in your resin creations.

Prepare and Mix Resin Carefully

Bubbles can often occur from hurried mixing or from air trapped in the flower petals themselves. Always combine your resin and hardener slowly and gently, stirring in one direction to minimise air introduction. Choosing a resin with enhanced degassing properties—like the Trasparente multipurpose epoxy—further helps unwanted bubbles rise and dissipate before the resin cures.

Layering and Surface Techniques

For best results, pour your resin in several thin layers rather than one thick coat. Place your dried flower in a light first layer, then add more resin gently in stages. After each pour, pause to inspect for any visible bubbles at the surface—these can be popped easily with a toothpick, a cocktail stick, or a quick pass of gentle heat, such as from a heat gun or lighter held at a distance.

When This Matters Most

Preventing bubbles is especially important for pieces where transparency is key, such as jewellery, coasters, or display blocks. The clarity allows your embedded natural elements—like the prepped dried flowers—to stand out beautifully, free from distracting imperfections.
