The best ways to reduce bubbles working with Epoxy Resin

Artistic and decorative creations made with epoxy resin are fascinating, but nothing can ruin them more quickly than annoying air bubbles trapped in the resin itself. Fortunately, there are effective methods to prevent and eliminate these bubbles, ensuring flawless results. In this article, we will explore the key strategies to avoid epoxy bubbles, ensuring that your creations are always defect-free.


One of the basic ways to avoid the formation of microbubbles is the mixing process. Too often, bubbles form due to inadequate mixing It is crucial to mix the resin carefully and carefully to minimize the risk of air bubbles.

The secret lies in mixing the resin from the bottom up, rather than adopting simple rotational movements. This helps to incorporate air evenly and prevent the accumulation of bubbles. Choosing a slow, deliberate movement while stirring can be the difference between a flawless result and one full of annoying bubbles.

Ideal temperature for bubble-free Epoxy Resin creativity

The temperature of the environment in which you work with epoxy resin is another crucial factor in avoiding the formation of bubbles. A temperature above 20 degrees centigrade can increase the viscosity of the resin, making it easier to trap air bubbles during the mixing process. Keeping the environment at a temperature slightly below 20 degrees can greatly help prevent it.

Resin`s type and tools for working with Epoxies

Choosing the right resin`s type can make all the difference in the bubble-free creation process. Opting for less viscous resins, such as “Transparent” from ResinPro, can greatly decrease the appearance of bubbles. These fluid resins mix more easily and allow air to disperse evenly, reducing the risk of bubbles.

Using of special tools, such as the anti-bubble mixer which specially designed for resin mixing can help to incorporate air evenly during the mixing process. In addition, using a tool to gently remove air bubbles trapped on the resin surface can further improve the quality of your creations.

In case you work with high viscosity resins, like our “Art-Pro Deluxe“, the best way to get bubble-free art work is applying resin by thin layers, helping by a heat-gun each time applying new level.

Working with large amounts of resin, we would suggest to try our slow epoxy resin for deep pouring – “Epoxytable-Five“. Because of long working time, all the bubbles have a chance to escape your project, before the catalysis is done. It is worth mentioning the importance of insulating the wooden surface before the main resin casting, to prevent appearing air at the late stages of the catalysis. The best way to do that – to apply our fast epoxy resin “Transparent” by thin layer and wait 6-8h before main pouring.

In summary, avoiding bubbles in epoxy resin requires attention to detail, from the correct mixing technique, to choosing the right temperature and the right tools. With a careful approach and an in-depth understanding of strategies to avoid bubbles, you will be able to create attention-grabbing resin artwork without any unwanted flaws.
