How to Fix Trapped Air Bubbles in Floral Resin Art

A simple technique to make your resin crystal clear—with just a toothpick and a little patience.

If you’ve ever poured resin over a real flower and ended up with a mysterious cluster of bubbles just beneath the surface… I see you. And I promise, you’re not alone.

Sometimes, even when we do everything "right," there’s a little cloud that shows up out of nowhere. But here’s the secret: it’s not a flaw in your resin. It’s not your flower. It’s air—tucked into the folds of the petals, hiding just out of reach.

Why Do Bubbles Get Trapped in Flower Resin Pieces?

Real flowers are full of little creases, curves, and textures—especially once they’ve been dried. As resin flows in, it pushes air out… most of the time. But every now and then, a stubborn little air pocket stays behind, clinging to the underside of a petal or sitting between layers.

Once the resin cures, that air becomes part of the piece. You can’t just pop it—it's sealed in. And the result is often a soft cloud or faint shape that doesn’t go away with sanding or topcoating. It's also hard to sand down without ruining your flowers.

A Satisfying Fix You Can Try

Watch it in action below:

In this video, I show you how to release those trapped air bubbles without starting over or hiding them beneath another thick layer. Here’s what I did:

1. I poured a thin layer of fresh resin over the cured piece.

2. Then, using a toothpick, I gently pressed into the bubble cluster.

3. As I nudged the air, the new resin flowed into those pockets.

4. The bubble vanishes—not because it was buried, but because it was replaced.

It’s slow work, but it’s so worth it.

When to Use This Technique

This little trick is a game-changer when you’re working on:

• Flower preservation pieces (like wedding or memorial blooms)

• Coasters or trays with real botanicals

• Multi-layer pours where each step matters

• Any project where clarity makes the story

If your piece looks slightly off and you can’t figure out why—check for air pockets. They might be just below the surface.

Tips for Resin Artists Working with Flowers

Whether you’re new to resin or have been pouring for years, here are a few things to keep in mind:

Fully dry your flowers before use—moisture creates bubbles, too Pour in thin layers to give resin time to settle🪻 Use soft tools like toothpicks or silicone stir sticks for gentle corrections🪻 Watch the edges—bubbles love to hide in corners and curls🪻 Work with patience—resin rewards you when you slow down

Final Thoughts

Working with real flowers in resin is like learning a language: every petal, every layer has something to say. And sometimes, the air gets caught in the conversation. But when you take your time, come back with a steady hand, and invite the air to leave—you give the piece room to shine again.
