Avoid Using Hairdryers or Heat Guns Too Close to the Resin

When working with brush-on resin, it can be tempting to speed up bubble removal by reaching for a hairdryer or heat gun. However, applying too much heat close to resin surfaces often brings more problems than solutions.

Why Direct Heat Can Be a Problem

Using hairdryers or heat guns too close to resin may cause the surface to cure unevenly or result in craters and ripples. Excessive heat can also introduce dust, distort delicate details, or create conditions where new bubbles form as the resin heats and cools rapidly. Instead of helping, direct blasts of heat often make finishing your project more difficult.

Gentler Ways to Minimise Bubbles

Achieving a clear, professional finish is easier with methods designed to minimise air bubbles from the start. Use slow, gentle mixing tools like the Anti Bubble Mixer for Epoxy Resin – Reusable Mixing Tool to stir resin without whipping in excess air. For application, a silicone brush helps apply resin smoothly and further reduces the risk of surface bubbles. To deal with minor bubbles on the surface, a light mist of pure isopropyl alcohol can help them rise and pop without the risks of direct heat exposure.

When This Matters

Careful bubble removal is especially important for thin resin coatings, clear finishes, or projects where every detail counts. Avoiding harsh heat prevents accidental flaws, saving you time and materials in the long run.
