Preventing and Removing Air Bubbles in Epoxy Resin Art

Dec 13, 2023

Epoxy resin art has become incredibly popular recently, captivating artists and enthusiasts with its versatility and beautiful visual effects. Whether you're making stunning coasters inspired by geodes, vibrant abstract paintings, or resin jewellery pieces, epoxy resin lets you bring your artistic ideas to life, and if you are looking to take your ideas and skills to a new level, taking online epoxy resin art classes and workshops can be an excellent way for any resin artist.

However, many artists struggle with a common issue when working with epoxy resin: Air Bubbles. These annoying bubbles can take away from the overall beauty of your artwork, leaving behind a bumpy surface or cloudy look. But don't worry; this blog will explore how to prevent and eliminate air bubbles in epoxy resin art. You can achieve perfect finishes for your resin art using the techniques and tips we'll discuss here.

Preventing Air Bubbles: Measures for Bubble-Free Creations

While creating epoxy resin art, prevention is key regarding air bubbles. By taking proactive measures, you can minimise the chances of air bubbles forming in your resin art and ensure a flawless finish. Here are some effective techniques to prevent air bubbles in epoxy resin art:

Work in a Dust-Free Environment

External contaminants such as dust particles or fabric can easily get trapped in the resin mixture and lead to the formation of air bubbles. To minimise this risk, work in a clean and well-ventilated area. Keeping the workspace free from any potential sources of dust or debris will go a long way in preventing air bubble formation.

Choose Suitable Tools and Materials

Specific tools and materials can quickly get air within the resin mixture. When selecting your tools, opt for smooth surfaces that don't introduce unnecessary air into the mix. Additionally, consider using materials specifically designed for epoxy resin art that have been proven to minimise air bubble formation.

Implement Effective Pouring Techniques

How you pour the resin can significantly impact the formation of air bubbles. Try pouring from a height or using a thin stream to encourage bubble escape. This allows any trapped air to rise to the surface and escape before the resin begins to cure. By pouring strategically, you can significantly reduce the occurrence of unwanted air bubbles in your artwork.

These measures can significantly increase your chances of creating bubble-free epoxy resin art. Working in a clean environment, using suitable tools and materials, and implementing effective pouring techniques will help you achieve a flawless finish in your creations.

Removing Air Bubbles: Techniques for Flawless Finishes

When it comes to epoxy resin art, even with careful prevention measures, there might still be a few air bubbles that manage to make their way into your project. But don't worry, because there are effective techniques for removing them and achieving flawless finishes. Let's explore two popular methods: using a heat gun or torch and sanding & polishing.

Using a Heat Gun or Torch

  • Start by ensuring that your resin piece is fully cured and hardened.
  • Hold a heat gun or torch at a safe distance from the surface of your artwork.
  • Gently direct the heat toward the areas with visible surface bubbles.
  • As the heat is applied, you will notice that the bubbles start to rise and disappear.
  • Continue this process until all the surface bubbles have been eliminated.
  • It's essential to keep the heat source moving and avoid overheating the resin.

Sanding and Polishing

  • After using the heat gun or torch, there may still be some imperfections left behind.
  • Start by sanding the resin piece with fine-grit sandpaper to address these imperfections.
  • Use circular motions and apply light pressure to gradually smooth out any remaining bumps or uneven surfaces caused by trapped air.
  • Once you are satisfied with the smoothness of your piece, move on to polishing.
  • Apply a polishing compound onto a soft cloth and gently buff the resin surface in circular motions.
  • This will help create a high-gloss finish and eliminate any minute imperfections.

Following these techniques ensures that your epoxy resin art pieces are free from unsightly air bubbles. Remember, patience and precision are essential throughout this process.

How to Create Bubble-Free Resin Jewellery: Tips for Stunning Wearable Art

When creating resin jewellery, preventing air bubbles is crucial to achieving a flawless and professional-looking result. Here are some specific considerations and step-by-step instructions to help you create stunning bubble-free resin jewellery:

Choose the Right Moulds

Opt for silicone moulds with smooth interiors to avoid trapping air bubbles in your resin jewellery. The smooth surface reduces the chances of air getting trapped during the pouring process.

Prepare Your Workspace

Before working with epoxy resin, ensure your workspace is clean, well-ventilated, and free from dust or other contaminants that could contribute to bubble formation.

Mix Resin and Hardener Thoroughly

Follow the manufacturer's instructions to mix the resin and hardener in the correct ratio. Proper mixing is essential for minimising air bubble formation. Use a slow stirring motion to prevent excessive air from being incorporated into the mixture.

Pour Slowly and Carefully

When pouring the resin into the mould, take your time and pour slowly in a thin stream. This technique allows any trapped air bubbles to escape as you pour.

Pop Air Bubbles

After pouring the resin into the mould, use a heat gun or torch on low heat to gently pop any surface bubbles that may have formed. Hold the heat source about 6–8 inches away from the surface and move it in a circular motion to distribute the heat evenly.

Let It Cure

Allow your resin jewellery piece to cure according to the manufacturer's instructions. Avoid disturbing or moving the piece during this time to prevent new air bubbles from forming.

Sanding and Polishing

Once cured, remove your resin jewellery from the mould and inspect it for any remaining imperfections caused by trapped air bubbles. Use fine-grit sandpaper or a polishing compound to smooth out any rough areas if necessary.

Following these tips, you can create stunning bubble-free resin jewellery showcasing your artistic talent. Remember, practice makes perfect, so don't be afraid to experiment with different techniques and moulds to discover what works best for you.


Mastering the art of epoxy resin takes time and practice. Don't be discouraged if you encounter some bubbles along the way – it's all part of the learning process. By following these essential practices and continuously practising, you'll be well on your way to creating stunning bubble-free epoxy resin art.
