Distance for Using a Heat Gun on Epoxy Resin

How Close Should You Hold the Heat Gun?

For best results, hold the heat gun about 10–15cm above the epoxy resin surface. This distance helps to gently warm the resin, encouraging bubbles to rise and disappear without risking local overheating or warping. Always keep the heat gun moving in a sweeping motion to prevent excessive heat build-up in one spot.

Practical Tips for Safe and Even Heating

• Begin at a distance: Start at 15cm or so and carefully lower closer if needed, never going under 10cm.
• Keep the gun moving: A constant motion avoids hotspots and ensures even heating across your resin.
• Monitor your resin: Watch for any signs of softening or discolouration as an indicator to move the heat gun further away.

When Does Precise Distance Matter Most?

Maintaining the correct distance is especially important for larger, thin pour surfaces or when seeking a flawless, professional finish. Overheating can cause imperfections, so care and the right equipment make all the difference in resin artistry.
