I used pourafloor.com a few years back. I chose a low voc epoxy and it has held up great it's been about 5 years now. If I remember right the smell was no stronger then a latex paint. You have to request the low voc.
I just paid $250 for a epoxy kit from Pour a Floor that included 5 pounds of flakes and a clear top coat told it will cover about 250 sq. ft. didn't get it yet but I'll keep you posted. hope it's not too good to be true.
epoxy coat and ucoatit are on my list i am now looking at legacy. the other company I can't find anything on but were great on the phone gave a lot of good info.
Sorry if this may be redundant on this fourm but research of epoxy floors brought me here any recommendation on who to use I am down to three companies.
