Does Stirring Speed Affect Bubbles in Resin?

← Back to How to keep resin from bubbling?

If you’ve ever battled tiny bubbles trapped in your resin castings or coatings, you may be wondering how much your stirring technique matters. The speed at which you stir is one of the simplest – and most overlooked – ways to keep resin crystal clear.

How Stirring Speed Influences Bubbles

Mixing your resin too quickly can introduce a lot of air, resulting in unwanted bubbles that become trapped in your final piece. Smooth, gentle stirring ensures that the resin and hardener combine evenly while minimising the amount of air whipped into the mixture. Patience here pays off; a slower stir gives bubbles time to rise and escape, leaving you with a clearer result.

Tips for Bubble-Free Resin Mixing

• Use a gentle technique: Move your mixing tool slowly, scraping the sides and bottom of your container to ensure a thorough blend.
• Choose the right tool: A dedicated tool like the Anti Bubble Mixer for Epoxy Resin – Reusable Mixing Tool is designed specifically to mix resin without introducing excess air.
• Let it rest: After mixing, allow your resin to sit for a few minutes so any bubbles can naturally rise to the surface before pouring.

When Stirring Speed Matters Most

Controlling your stirring speed is especially important for deep pours or large projects, where trapped bubbles can ruin clarity. Using a methodical, gentle approach can help avoid flaws, particularly if your resin has a long working time.
