Shot blasting concrete floor before epoxy?

Yeah, garagejournal is a good place for info. Actually that is where I first heard of shotblasting as an option a couple years back.

I called around locally to try and locate a shot blaster or diamond grinder/surfacer to use. The only thing I could find was a small 8-10" scarifier which seemed a little questionable to me. The wheel moved vertically instead of horizontally and I was afraid that would lead to visible grooves in the finished floor. Soooo, I'll do what I've done before and just acid etch it real good. This floor is new construction so there was zero oil, mud, etc on the floor fortunately.

I'm going to use the Sherwin Williams ArmorSeal 1000HS epoxy. It comes in a gray color or you can tint it. I've seen good reviews on it. It is similar to a product I used from Lowes a few years ago that was classified as an "Industrial Floor Coating" from the same company that has those Garage Kits. The industrial was not a water based epoxy though. They don't seem to sell it any longer so that is why I went looking for something else.
