So I just completed a epoxy in my mechanic garage. We accidentally sprinkled the anti skid sand by hand and in some areas, the sand is sticking out and the floor does not look like a smooth finish. Buddy of mine suggested, I use a floor buffer to lightly go over the affected areas, lightly sand in some the areas where there is excess sand to remove and recoat
Epoxy Floor Repair, Excess AntiSkid Sand

Why entire floor? It’s only in certain areasAlmost.... lightly sand ENTIRE floor and then recoat ENTIRE floor.
Mainly because clear coats do not "feather" or blend in well when you patch them you will clearly see the areas that were repaired (pun intended). If you're OK with this then carefully/precisely tape off the areas to be repaired being mindful that any area to be recoated will need to be completely deglossed before applying new clear coat.
The recoating is the same color, grey as you see in the pictures. So the color will blend in, it won’t be a clear coat. Would a floor buffer do the job of removing excess sand and deglossing?
Yes a 175 rpm floor maintainer with 120grit sanding screen/s will work. You're going to have the same issue with trying to feather/blend repair areas with non-repair areas.... The "fix" may end up worse than what you already have.
I’m not understanding. I’ve already used two topcoats of the same epoxy, same color. Why would the same color not blend in?
Oh ok, and what if I just buff and slightly grind a little give a light coat?
I’m using the Benjamin Moore v500 polyurethane shadow grey color
I’m just looking for a smooth finish
It is a mechanic garage so I don’t expect a perfect smooth layer of flooring
Was not arguing, just trying to figure out the best solution. Thanks for the input
It is a 2 part kit. Part A and Part B

Just an FYI... Coatings do not blend over repaired areas like latex paint on a wall does. This is a typical misunderstanding by those who don't work with coatings every day. This is because coatings are thicker and their properties do not allow them to wet out like traditional paint. It's usually fairly obvious where a section of new coating has been applied. The overlap roller marks can be seen, as well as a slightly different tone and gloss. The tone and gloss difference can diminish with time and traffic, but the area where it overlaps does not.
