I used the Griggs two-part, water-based epoxy paint and have had excellent
results. It's been over a year and nothing seems to phase it. I put down
two coats over an acid etched new concrete floor. After etching, be sure to
thoroughly wash the floor. It took several washes with a power washer to
get the grit loose.
I followed Griggs advice and added a top coat of their urethane (about $90
gallon). They said the urethane top coat was used in buildings with a lot
of traffic (like municipal auditoriums). It adds extra protection. I also
used the urethane to paint my metal benches and it also worked great.
The overall coating is tough and seems to be impervious to gas, oil, lacquer
thinner and beer.

No interest in Griggs other than a happy customer.

Subject: Re: Not the floor paint thread again...
hi:
i have been meaning to convey my floor painting experience. now seems as
good a time as ever. on advice from listers, i avoided behr one part
epoxy and bought griggs two part , water based epoxy at $30 / gal. this
gets thinned over 100%
and so is a pretty good value. i chose white and am glad i did.
since my floor is new, the purpose of acid treatment is to
promote adesion ("tooth"). this can also be done by sandblasting or by
using a floor sander. since acid is not
pleasant , i used a floor sander- which also leveled things
out a bit.
i super thinned the first coat of paint (as per the instructions) to
allow penetration into the concrete. i suspect that this was the problem
with the behr paint which is so thick it tends to sit on the surface.
behr's instructions call for no thinning.
so far, so good.
