I recently did a floor with a gloss urethane top coat and when applying the top coat, I missed the recoat window. It was 18 hours in, i though it would chemically bond but didn’t. Now I’m planning to fix it this weekend. I layed it at 5-7 mils thick and here was the finish result. This was 8 days after I finished, I know it wasn’t a contamination issue because I vacuumed the **** out of the floor before applying. There was no ventilation in this enclosed room and I think that was the issue. Anyway, I’m looking for solutions. I’m thinking to sand starting at 150 and work my way down to 80 to hopefully get down to epoxy, vacuum, acetone wipe, and reapply the same high gloss urethane top coat. Looking for suggestions on anything I should do differently. Thanks in advance.

If coating outside the recoat window always degloss and thoroughly wipe down with alcohol (iso or denatured) just prior to recoating. Vacuuming alone will not address chemical contaminants. We recommend against acetone as it flashes off to quickly. You're on the right track with sanding down the floor but I doubt you'll need to get down to 80grit, 120grit sanding screens should do you fine.
BTW, good lookin floor.
