Where are you located? The reason I ask, the guy running the grinder looks a lot like my brother (gets grainy when I zoom in so I can’t tell for certain) who does commercial floor prep and epoxy floors.
And my advice to anyone considering epoxy, I second what
@cosgig said, don’t bother with the stuff from Lowe’s or hd, spend the money once and have a commercial company come in, grind the floor and use industrial epoxy, it’ll last WAY longer.
