Achieving a flawless, glass-like finish on resin tables often requires removing tiny bubbles that appear during mixing and pouring. Using a heat gun or torch is a popular and effective method for this crucial step.
Why Remove Bubbles from Resin?
Air bubbles trapped in epoxy resin can remain as unsightly marks once the resin cures. These imperfections can detract from the clarity and strength of your finished table. Ensuring a smooth surface means taking action shortly after pouring, before the resin begins to gel.
How to Use a Heat Gun or Torch
Once your resin is freshly poured and levelled, hold a heat gun or butane torch just above the surface. Move it smoothly but steadily over the resin, avoiding prolonged exposure in one spot. The gentle heat encourages bubbles to rise and break, leaving the surface clear. For safety and to minimise the risk of overheating, keep the tool in motion and avoid letting the flame or hot air linger.
If you’re using a kit such as the “River-Table” – Complete Kit for Creating Your First Epoxy Resin Table, always follow the included instructions for best results.
When Precise Bubble Removal Matters Most
- Thicker pours—bubbles are harder to escape naturally in deep resin layers.
- Projects with clear or coloured resin where high clarity is essential.
- Wood and resin tables where smoothness is key to durability and appearance.
