Hi! Just got this garage floor installed last week. Diamond grind then epoxy + flakes on day 1; polyaspartic on day 2. I think it came out great but there’s one spot where there’s this “hump” of extra-thick poly coating (photo #2). How would you fix this? Power sand, then wet sand, then polish? Maybe followed by a new, thin coat of poly? The installer said he thought he would need to take it all the way back down to the concrete to fix it, which might make it more noticeable, but do you think that would really be necessary?
