Compounds which are applied to new concrete to seal water in for curing. This makes it possible to get onto the concrete quickly. Traditionally, slabs were kept wet for curing by traditional means such as wet straw, burlap, plastic film, etc. This kept the concrete wet for the 28 day "wet cure" but did not allow for use of the slab during the curing period. Whenever curing agents have been used, a bond test should be run to determine the compatibility of the adhesive to the curing compounds. Curing compounds must be removed in areas where calcium chloride tests are being run. When moisture testing fails, curing agents need to be removed to allow the concrete to dry.
