Specially formulated for cleaning and preparing bare cement surfaces for a UCoat It floor coating system, UPrep-CLC is easy to apply, easy to use, easy to remove and works effortlessly. Dilute 7:1 with water and apply to a wet surface. Agitate with a stiff-bristled brush and rinse clean. Coverage is 2 qt bottles (in dilution) for every 200-300 sq.ft. For example, for a typical 2½ car garage (576 sq.ft.), purchase 4 quart bottles.
