Integral color, in liquid or powder form, can be a low-maintenance option for creating natural-looking decorative concrete surfaces. By adding color before the concrete is poured, contractors can expect evenly dispersed pigment. Once the surface has hardened, the color will not wear off or chip. Concrete dye also provides lasting color by penetrating deep into the porous surface. Manufacturers have formulated long-lasting colors that resist the effects of UV rays, chemicals, and harsh weather conditions. The following companies offer a selection of coloring products for indoor and outdoor applications.
