How do I fix bubbles, bugs, or torch burns locked in cured epoxy?

The fix is the same for trapped air bubbles, flies or bugs that landed in the pour, and white, bumpy torch burns: sand the problem out of the cured layer, then re-coat.

1. Let the epoxy cure at least 12 hours before sanding. 2. Sand down until the bubbles or debris are gone. Start with a coarse grit, then finish the entire surface with 220-320 grit. Depth varies with every project and cannot be judged from a photo. 3. Wipe off all sanding dust with a clean, lint-free rag and acetone or denatured alcohol. Do not use paint thinner or mineral spirits. Let the surface dry completely. 4. Pour a new flood coat of UltraClear Bar & Table Top Epoxy. The sanded surface looks white and cloudy, but the new coat fills the scratches and restores the clear, glass-like finish.

Try not to sand through to the wood. If you do expose wood, apply a seal coat before the flood coat (two or three on porous wood) or bubbles will rise into the new pour. If a full layer of epoxy remains, no seal coat is needed.

Bubbles that kept rising after the 20-minute heat-gun window mean the surface was not fully sealed, not that the epoxy failed. Sanding is the only method we recommend; a Dremel is at your own risk. Never use a heat gun or torch on Bar & Table Top Epoxy poured more than 20 minutes earlier.
