Should you use heat on an epoxy seal coat?

Generally, you'll only use heat (a heat gun or propane torch) to pop bubbles on the flood coat surface area. There are two exceptions, which we'll list here:

• If you are brushing a backsplash, you can use a heat gun or propane torch to remove the brush stroke impressions from the epoxy.
• If your project has live edges, you'll be using a brush right after you pour your flood coat to fill in the crevices and grooves with epoxy as it runs down the sides. For this part you might use a heat gun to smooth out the brush strokes after your flood coat settles a bit.

In the vast majority of situations, the flood coat will remove any irregularities in the seal coat once you pour it on.
