Can I Use a Torch to Remove Bubbles?

← Back to How do you remove air bubbles from epoxy resin?

Air bubbles can spoil the look of cured epoxy resin. Many resin artists consider using a torch as a quick way to remove surface bubbles, but it’s important to do so with care to protect both your project and your safety.

How Can a Torch Remove Bubbles?

Applying gentle heat using a torch can help air bubbles on the resin’s surface rise and burst, leaving a smoother finish. This method is common for shallow pours or thin resin coatings because a brief, controlled pass of the flame encourages bubbles to dissipate without disturbing the resin’s clarity.

Safety Tips for Using a Torch

• Never hold the torch flame in one spot for too long, as overheating can cause yellowing, scorching, or even damage the surface.
• Keep your work area well ventilated and free from flammable materials.
• Work with small, controlled movements — sweeping the flame just above the resin surface for a few seconds is typically enough.

If you’re unsure, consider using a heat tool such as the Gas Heat Gun for Epoxy Resin for more precise, adjustable heat.

Alternatives to Torch Removal

While torches are effective, there are alternatives for smoother results. An anti bubble mixer can help reduce the bubbles formed during mixing by stirring gently. Heat guns, such as the 1500W Heat Gun, offer a safer, targeted heat that’s great for larger resin projects or when you want to avoid open flames.

When This Matters

Choosing between a torch and other methods is most important when working on intricate projects or indoors. For small, detailed work a torch may offer fast results, but for larger pieces or safety concerns, alternative bubble removal tools can give peace of mind.
