Back-Rolling the Clear Topcoat for Smooth Finish

What happens here

Immediately after spreading the clear epoxy topcoat with a squeegee, use long-handled paint rollers to 'back-roll' the entire surface. This essential action helps to further level the epoxy, remove any squeegee lines, release trapped air bubbles, and ensure a uniform, smooth, and even finish across the entire floor, as mentioned in the video's audio cue, 'You want to smooth this out first?'

Goal: Achieve a uniform and bubble-free final epoxy finish.
