Color Juice Silicate Concrete Colorant from American Decorative Concrete is a UV-stable pigment coloring system that can be applied to existing concrete. It uses 100 particle-size pigments (similar to those used in ink-jet printers for high-resolution photographs) for even penetration into a slab surface and includes an integral hardener that bonds pigment to concrete to protect color and enhance surface durability. Engineered for exterior or interior concrete, Color Juice is packaged as a concentrate (in 12 translucent and 16 pastel colors) and requires little cleanup. It can be used with Color Juice exterior or interior sealers.
