Two methods can be used to rid of bubbles in an epoxy coating:
1. Roll and Tip Method: Bubbles that persist in the coating can be broken with a disposable bristle brush by lightly dragging it across the surface after rolling the product out.
2. Propane Torch: Quickly and lightly fan 6-8 inches above the uncured surface with a propane torch to accomplish bubble popping with greater speed. Avoid overheating an area as this could cause the epoxy film to pull away from the surface creating craters.
NOTE: When coating a porous surface like concrete or wood, overheating to pop bubbles with a torch can cause the expansion of any air in the pores of the substrate and can make the bubble situation worse.
