Why Does My Resin Have Bubbles? Resin Mixing & Pouring Tips

Q: How to Minimise and Remove Bubbles

Mix Slowly: Stir your resin and hardener gently for the time recommended on your product instructions, rather than whisking or shaking. Slow mixing reduces trapped air. Gentle Pouring: Allow the resin mixture to flow slowly into your mould from a low height. Pouring too fast can introduce extra bubbles. Surface Treatment: After pouring, use a toothpick or pin to burst any surface bubbles. Briefly applying heat from a small torch or heat gun can help remaining bubbles rise and pop without disturbing your work. Choose the Right Kit: Starter kits such as the Evershine Collection provide clear, well-formulated resin that's easier to degas and work with.

Resin bubbles are a common frustration for both beginners and experienced crafters. They can interrupt the clarity of your pieces, so understanding why they form and how to handle them is key for clean, professional results.

What Causes Bubbles in Resin?

Bubbles naturally appear during the mixing process or when resin is poured into a mould. Agitating the mixture too quickly or pouring rapidly introduces air, leading to visible droplets within your finished resin work. Cold environments or overly thick pours can also trap air, making it harder for bubbles to reach the surface before the resin begins to set.

When This Matters Most

Bubbles are especially noticeable in high-clarity pieces and small moulds, such as when crafting jewellery or combining resin with olive wood for rings. For detailed projects, taking care to avoid trapped air is crucial in achieving a flawless, glass-like finish.
