    Great paint as it gives a tough epoxy base while drying for recoat in hours alowing multiple coats in one day. Best of all it can be sprayed at home without worrying about dangerous and toxic fumes. I was able to spray in my basement without any significant fumes in the house.Best applied in cool temperatures and high humidity to avoid a rough surface.Also applies very well with a foam roller. I found that there was no advantage to tipping with a foam brush as the paint flowed out beatifully on its owb while the brush left streaks.

    Using water borne wood finish products for furniture on a regular basis, this was the first water borne epoxy primer I have used. It was easy to mix and apply but be aware, the pot life is greatly limited by temp/humidity. Plan on discarding the first applicators and if applying in 80 degree F weather, use a 2-3 hr max pot life. Also, the coverage was greater than expected as it refers to recommended film tickness. The gallon can provides 2 coats of rolled on coverage for the square footage cited.
