How do I avoid bubbles?

There are a few precautions you can take to avoid excess bubbles when working with Industrial Clear:

  • stir slowly, by hand, to avoid introducing excess bubbles into the resin batch.
  • after the resin has been poured and spread, use a quick pass with a flame torch to remove bubbles that have risen to the surface of the resin. Repeat this step if bubbles continue to release, taking care not to hold the flame too close to the resin surface or in one spot for too long.  Do not use the torch on resin that has passed the 45 minute working window or you may end up with surface imperfections in your cured resin.
  • When sealing over a porous material like wood, sealing first (with either a sealant designed for wood or a very thin coat of Industrial Clear applied with a brush or gloved hand) will create a barrier that prevents trapped air from releasing into the resin as bubbles. Pay particular attention to seal any cracks, knots or voids in the wood. Ensure the first sealant layer has adequate time to dry before applying the final coat of Industrial Clear.
