HELP! Poor prep showing through floor finish

[betzgb]

Well, this post is to confirm that 2 low cost guys that claim to know how to use a diamond grinder to prepare a floor at a low low cost is not a good idea...

Once they were done applying the top coat it, the gloss brings out all the swirl marks in the concrete from the grinding process. I love the light gray color in a solid color but the swirl marks are going to drive me crazy. Anyone have ideas on how to keep the solid light gray color and mask all the poor prep work? High solids build up? single color flakes with top coat? I do lots of car work so needs to stand up to brake cleaners, oil, chemicals, etc. Also, some areas have a dull (flat) finish. Does that mean the topcoat pooled in those areas?

Lightly grind the coating, apply a full broadcast of flecks, scrape them well and vacuum, and two coats of topcoat and they will disappear!

That floor looks nice. The swirl marks are not bad.

Thanks for the replies. Couple more Pics showing how bad it is in the right light

Too bad as I really like the look otherwise and I really wanted a solid color to easily spot small parts dropped on the floor. There seems to be a debate on whether a full flake system in single color will look good or not. Anyone have some pics to share?

You could scuff off the gloss and add (1) healthy coat of 100% Solids Epoxy.
The telegraphing swirl marks would be lessened.

If you wanted a gloss, solid color floor, a full flake is not going to please you, IMO.

Also a partial fleck broadcast would visually break up this monolithic surface. Unfortunately with large high gloss surfaces they show EVERYTHING so prep becomes very important.
