How Do I Get Bubbles Out Of Epoxy Resin?

Without question, the best way to get bubbles out of epoxy resin is with an Artist’s Torch. Whether you use a handheld butane torch or a bigger propane torch for larger projects, the flame from a torch is hot enough to thin out the resin, allowing bubbles to escape.

It’s your best bet against air bubbles every time! Read our instructions and recommended techniques below.

Some More Handy Tips & Ideas To Prevent  Resin Bubbles: 

  • Seal anything that may contain air, like wood, inkjet prints or paper with a brush on or spray sealant.

  • Make sure the resin is warm ( 75-85 F or 24-30C is ideal. ) 
    You can give cold resin a warm water bath if you like by placing the unopened resin and hardener bottles in a warm water bath for 20 minutes or so, drying them off thoroughly before you measure and mix.

  • Stir your resin mixture slowly: whipping it will induce more bubbles. 

  • Pour your resin out slowly and pour close to the resin surface. 

  • Pour in thin layers: if you pour too thick, bubbles won’t have a chance to escape to the top or get torched out. 

  • Always use a torch/ to get rid of bubbles: heat gun just can’t match the heat of a flame.
