Concrete can be kept moist in a number of ways, including leaving its forms in place, sprinkling, ponding, and using moisture-retention covers or a seal coat that is applied as liquid and then hardens to form a thin membrane. Curing methods that use water, such as sprinkling, ponding, and using wet coverings, are the most effective means and should be used whenever practicable. Although not usually as effective as curing with wet coverings, moisture retention membranes are widely used because of their convenience. In any case, the most important consideration is that the surface of the concrete be kept uniformly wet or moist. Partial drying of any part of the surface of a slab can result in crazing and cracking. Curing compounds will affect the bonding properties of adhesives and should not be used on slabs that are to receive resilient flooring or other adhesive-applied finishes unless they are known to be compatible with the adhesive. Curing compounds are also not recommended for slabs that will be given a further surface treatment.
