How can I remove bubbles from resin on wood?

Bubbles can be a common issue when working with resin on wood, but using the right techniques will ensure a smooth, professional result. Here’s how to achieve a flawless resin finish on your wooden creations.

Why Do Bubbles Appear in Resin?

When combining resin and hardener or pouring resin onto wood, air can become trapped either during mixing or as the resin seeps into the wooden surface’s pores. Temperature changes or mixing too vigorously can also introduce additional bubbles.

Effective Methods for Bubble Removal

After pouring your resin, allow it to settle for a few minutes to let initial bubbles rise. Then, gently pass a heat gun or small craft torch quickly over the surface—this encourages trapped air to escape without overheating or scorching the resin. Avoid direct contact and keep the heat source moving to prevent damage.

If using a domed mould or deep wood grain, repeat the process as needed during the initial curing phase.
Consider using low-viscosity resins like Icrystal Clear Epoxy for easier bubble release and optimal clarity on wooden surfaces.

Practical Tips for Best Results

Mix resin and hardener slowly to limit air entrapment.
Warm your resin slightly before use (as directed) for easier bubble release.
Seal very porous wood with a thin resin coat first before your main pour.
Work in a dust-free, controlled environment to minimise imperfections.

When Bubble Removal Matters Most

Bubbles are particularly noticeable in clear coats and artistic finishes on tables, resin art, or decorative wood projects—careful removal is essential for a pristine, glass-like appearance.
