Color in concrete pavers is achieved by adding pigment to the concrete mix during production. The cement in the concrete mix holds the pigments in place. Normal wear form traffic or weather gradually erodes the cement and pigment particles, causing a color change over time.
Like all pavements, concrete pavers receive dirt from foot or tire traffic which changes the surface color. Cleaning and sealing the surface of the concrete pavers can moderate the rate of color change. Besides enhancing the pavers’ color, sealers can prevent dirt from lodging in their surface.
