Bubbles can spoil the look of your resin piece, especially in large pours like river tables. If you don’t have a vacuum pump, there are still effective ways to deal with trapped air and achieve a clear, professional finish.
Choose the Right Tools and Resin
Selecting a resin designed for deep casting helps reduce the risk of trapped bubbles. Products like Epoxytable 10-Ten offer low viscosity and a longer working time, which allows air to escape naturally. Mixing with a gentle, purpose-made tool such as the Anti Bubble Mixer for Epoxy Resin helps prevent generating bubbles at the start.
Layering and Surface Treatments
If you’re working on a deep pour or river table, pour in several layers. Allow each layer to settle before adding the next, letting trapped air work its way out over time. For any bubbles that rise to the surface, light passes with a 1500W heat gun will gently pop them. Alternatively, a fine mist of isopropyl alcohol can be sprayed across the surface to burst fine bubbles.
When this Matters Most
This approach is particularly helpful for large-scale casts, deep pours, or river tables where access to a vacuum pump isn’t practical. Using these simple techniques helps ensure clarity and strength in your final piece, even on professional projects.
