cure & seal
Also, if your flatwork isn't finished yet, talk with your concrete contractor about any plans to coat the floor. When I built my shop last fall, I subbed out the concrete work; I had in mind that I wanted to coat the floor somehow, but didn't know anything about it yet. The concrete guys put a product called Cure & Seal on the slab (supposedly helps it cure stronger? it does seal the concrete somewhat, compared to the untreated slab in my parent's garage), and later when researching epoxy coatings, I was told by several representatives that in order to get a satisfactory adhesion, I would have to grind the entire floor to remove the Cure & Seal. I ultimately decided to skip out on the coating (very bummed...); at least at the time, the cost and labor to grind the floor seemed overwhelming.
The Cure & Seal, I also discovered later, becomes tacky when you spill gasoline on it, though engine oil comes up readily if you get to it quickly.
FWIW, after considerable research, I was looking at either:
- Sherwin Williams ArmorSeal 1000HS
or
- UCoatIt(.com)
