I doubt there is any big difference -- industrial products usually have
less voc to meet OSHA and EPA regulations. The most important factor is
the prep work. The concrete has to be dry, and you need to acid etch and
rinse per the instructions. My shop floor has two coats of the Home
Depot Rustoleum epoxy, and it has held up quite well over the past two
years.

I am going to paint my shop (garage) floor with epoxy paint. Rustolium sells
two grades, "Garage floor paint epoxy " and "Industrial epoxy" paint. I
purchased the "Industrial" quality on the assumption that if it cost more and
is more difficult to apply that it must be better. Does anyone have
sugestions/precautions/advice on applying these products? How good are they?
