ABSTRACT:
A concrete cure is provided which is totally water based and completely void of solvents. A moisture impermeable film is attained when the cure is applied to fresh concrete. The cure forms a barrier over the concrete allowing it to retain over 95% of the mixing water for a minimum of 72 hours when applied at the rate of 200 ft.sup.2 /gallon (5m.sup.2 /dm.sup.3). The concrete cure of the invention is a mixture of a hydrocarbon resin, emulsifying agents, paraffinic wax, and water. The cure may be provided in a clear or pigmented formulation. A method for making the concrete cure is also disclosed.
