How To Get Bubbles Out Of Resin Without Torch

Resin provides an excellent solution for producing a glossy, durable finish for a wide range of surfaces. It’s used in a variety of applications, such as tabletops, jewelry, and artwork. But if you’ve worked with resin before, you know that it can be challenging. One issue that often crops up is bubbles in the final product.

Bubbles are an eyesore, and they can ruin the appearance of your project. Luckily, there are several methods you can use to get bubbles out of resin without a torch. In this article, we’ll delve into these methods and share tips for successfully eliminating bubbles in your resin projects.

What Causes Bubbles In Resin?

Before we delve into how to eliminate bubbles, it’s essential to understand the causes of bubbles. Bubbles are often formed during the mixing process when you’re combining the resin and catalyst.

The catalyst is responsible for hardening the resin, and as a result, generates heat. This heat causes the resin to release gas, which turns into bubbles. Bubbles can also be formed when the resin is mixed too vigorously, and this atmosphere eventually traps air.

How To Get Bubbles Out Of Resin Without Torch

When it comes to eliminating bubbles in resin, there are a few methods to try. The approach you choose will depend on the size and location of the bubbles, as well as the amount of time you have to work with the resin.

Method 1: Warm The Resin

One of the simplest ways to eliminate bubbles in resin is to warm the resin. Warming up the resin promotes the release of bubbles, reducing the number of bubbles in your finished product.

To do this, you can place your unopened resin and catalyst in a warm water bath or simply transfer the mixture from the container to a warm bowl. The heat will help the resin to release trapped air bubbles naturally.

Method 2: Ultrasonic Jewelry Cleaner

Another way to get bubbles out of resin without using a torch is to use an ultrasonic jewelry cleaner. This method is suitable for small to medium-sized objects.

The process involves filling the cleaner with warm water and then placing the item you want to clean into the device. Turn on the ultrasonic cleaner, and this will produce high-frequency sound waves that produce millions of tiny bubbles in the water.

The bubbles in the water will travel in and out of the resin, dislodging air bubbles in the process. This method can take several minutes to eliminate bubbles, so it’s essential to be patient.

Method 3: Vacuum Chamber

A vacuum chamber is an ideal option for removing large quantities of bubbles from resin. The vacuum chamber works by placing your mixture into a sealed container, and then creating a vacuum to remove the trapped air.

This method can be expensive, so it may not be suitable for small projects or hobbyists. However, if you plan to undertake large-scale projects, such as resin casting, investing in a vacuum chamber could save you time and money.

Method 4: Blow Torch

While this article focuses on how to get bubbles out of resin without a torch, a blow torch is an effective solution for eliminating bubbles in resin.

Using a blow torch involves running the flame over the resin surface to pop the bubbles. The heat will also prompt the resin to flow over the surface, smoothing out any wrinkles or bumps.

However, using a torch requires caution and experience to avoid under or overheating the resin. So if you’ve never used a torch before, this method is best avoided.


Q1: Why Can’t I Use A Torch?

A: You can use a torch to get bubbles out of resin, but it requires experience and caution to avoid overheating the resin or causing unintentional damage.

Q2: Can I Use A Vacuum Chamber If I’m Working With A Small Project?

A: While a vacuum chamber is an excellent solution for removing bubbles in resin, it can be costly for small projects. It’s essential to weigh the pros and cons before investing in a vacuum chamber.

Q3: Does Warming Resin Work For All Types Of Resin?

A: Warming resin is a simple solution that can work with most types of resin, although it’s always wise to check the manufacturer’s recommendations first.

Q4: Can I Use An Ultrasonic Jewelry Cleaner To Eliminate Bubbles In Large Projects?

A: Ultrasonic jewelry cleaners are ideal for small to medium-sized projects, so if you’re working on a large project, it may not be a viable solution.
