A multi-zone cementitious product, which includes a base zone made of a first cementitious material composition and forming a portion of the product. At least one facing zone is adjacent to and bonded to the base zone, the facing zone made of a second cementitious material composition and forming at least one exterior face of said product which is visible when the product is installed. A disrupted boundary layer is between the facing zone and the base zone, and includes material from both the facing zone and the base zone. The disrupted boundary layer bonds the facing zone to the base zone. The facing zone has a thickness sufficient to prevent the base zone from being visible when the product is installed.
