all day job, 2 coats of gray and two clear coats around 2 hours for each to dry, had a freind toss my flakes that's the only help I had with it really no major job
I actually put hellfire down first and wasent happy with, i didnt use the 18 inch roller and ended up with alot of roller marks so i decided to go with the nohr s so i had to sand the floor with a buffer, i think you would normally acid etch the floor on bare concrete
