Trouble with Bubbles in Your UV Resin? Here’s How to Prevent and Fix Them (Without Stress!)

Ever made a gorgeous UV resin piece, only to find tiny bubbles messing up that perfect glassy look? Ugh, we’ve all been there. The good news? Resin bubbles are super common—especially when you’re starting out—and the better news is, they’re totally fixable.

This guide covers why bubbles show up, how to stop them before they happen, and what to do if they’ve already snuck into your piece. Whether you’re casting a charm or sealing a photo, here’s how to get that ultra-clear finish using RWAtelier UV resin, which is already formulated to help reduce bubbles.

When Do Bubbles Appear?

• Mixing too fast – like you’re whipping cream (please don’t!).
• Pouring too quickly – creates turbulence that traps air.
• Using cold resin – it gets thick and makes air harder to escape.
• Working in a cold room – same deal, thicker resin = more bubbles.
• Embedding stuff – like flowers, glitter, or charms that may have air trapped inside.

How to Prevent Bubbles Before They Begin

• Warm your resin: Put the sealed bottle in warm water for 5–10 minutes.
• Mix gently: Stir slowly with a stick—toothpick style!
• Let it sit: Give it a minute after mixing to release bubbles naturally.
• Tilt the mold: Let the resin flow in along the sides, not straight down.
• Seal porous items: Like dried flowers, seal them first with Mod Podge or resin.

Already Have Bubbles? Here’s How to Fix Them

• Surface bubbles: Pop with a toothpick.
• Stubborn bubbles: Use a lighter/mini torch, keep it moving!
• Isopropyl alcohol: Light spray breaks surface tension and clears up bubbles.
• Deep bubbles: Use layering—cure thin layers for best clarity.

Extra Pro Tips

• Clear molds help spot bubbles early.
• Thin layers let bubbles escape more easily.
• Go easy on alcohol inks—they can trap air if used too much.

Final Thoughts

Bubbles happen. Even seasoned artists deal with them. The trick is learning to work with your resin. With RWAtelier UV resin, you’re already ahead of the game. Now you’ve got the know-how to create those clean, glass-like pieces that truly shine.

Take your time, stir with care, and most importantly—have fun with it!
