"Stamped" concrete is cast-in-place concrete in which a pattern has been made by placing a mold over it before it has cured. In this process, the concrete needs to be a wet mix with an air-entraining agent in order to ease leveling. Once placed, the wet concrete is worked over with a pierced tamper, to ensure a good cover of cement over the aggregate, and is screeded and leveled. At this stage, a coloring admixture can be added along with a chemical hardener.
