Black Out Floor Polish is a low-maintenance, slip-resistant polish that combines acrylic polymers, plasticizers & black pigment to beautify & protect porous asphalt plank surfaces located in places such as a U.S. post office. Polish enhances gloss for better light reflection & restores black coloration grayed by daily wear. Each coat quickly dries between 30 minutes to 1 hour. When properly maintained, the polish meets or exceeds slip-resistance standards established by CSPA & UL & is tested in accordance with ASTM D-2047.
