Moist Curing. Probably the best method for curing concrete, although sometimes the least practical, is to flood the surface continuously with water for the first week after placement. Do not let the concrete dry out. Contractors sometimes will recommend to a homeowner to wet a new driveway during its first week.f the surface of hardened concrete is wet for a long time, some of the water will be absorbed and will saturate the concrete. While salt itself does not harm the concrete's surface, its melting of ice and snow keeps the surface water-saturated.
