One of the most common challenges in resin encapsulation is bubbles, which can spoil the clarity of your work. By understanding how to prevent them, you can achieve smooth, glass-like results whether you’re casting small trinkets or artistic tabletops.
Choose the Right Resin for Clear Results
Low-viscosity resins help bubbles rise and escape more easily before the surface sets. For thinner layers and detailed projects, a clear epoxy like “Trasparente” ensures a liquid, bubble-free finish for encapsulations up to 2cm. For larger castings or thicker pours, “EpoxyTable 5-Five” is specially formulated for deep castings, reducing the risk of trapped air even in layers up to 5cm. Selecting the correct resin for your project thickness is key to minimising bubbles and achieving a professional-grade finish.
Pouring and Layering Techniques
Bubbles are most often trapped during mixing or as the resin flows around objects. To avoid this, pour resin slowly and steadily in a thin stream, allowing any air to escape as you go. When working with multi-dimensional or thick items, pour in layers—let each layer partially cure before adding the next. This approach helps encapsulate objects effectively and reduces the chance for bubbles to form deep inside.
Dealing With Surface Bubbles
Even with careful pouring, some bubbles may appear at the surface. Use a heat gun or a small flame (with caution) to gently pass over the resin’s surface just after pouring. The heat helps break any bubbles, leaving a smooth top. Avoid overheating, especially with larger projects or with resins designed for thinner layers.
When Bubble Control Matters Most
Bubble avoidance is especially important in jewellery, clear art pieces, or memorial keepsakes—where clarity is central to the appeal. Choosing purpose-made kits, such as the Evershine Collection for detailed works, can further support flawless encapsulation of intricate elements.
