When placed on a cementitious surface, Kemco Pro Series Chemical Stains infuse color into the surface, becoming a permanent part of the substrate that will not crack, chip, fade, or peel. The single-component coloring solution chemically reacts with particles in the cement, causing broad drifts of color and mottled surface effects. The result is a translucent, variegated effect that showcases the character of the substrate. Kemco Industries, 877-450-5877, www.kemcooil.com
