Treating Thick vs Thin Epoxy Pours for Bubble Removal

Q: How Bubble Behaviour Differs

With thin epoxy layers , air bubbles are less of a challenge since they can readily rise to the surface and pop on their own. Conversely, thicker pours trap bubbles more easily, making it harder for them to escape. This means that thicker resin pours typically demand more active steps and patience to achieve a smooth result.

Q: Effective Bubble Removal Techniques

Thin Pours: Mix gently and wait a few minutes for bubbles to surface naturally. You can use an Anti Bubble Mixer to minimise initial bubble introduction. Thick Pours: Plan on making repeated, gentle heating passes using a heat gun such as the Gas Heat Gun or 1500W Heat Gun . Allow more time between passes for air to rise, and avoid over-mixing or using excessive heat, as this can cause other issues.

Q: When This Matters Most

This distinction is especially important for deep castings, river tables, and intricate art pieces where clarity and a flawless surface are crucial. If you apply the same approach to all pours, you may end up with trapped bubbles in thick projects or wasted effort in thin ones.
