FRACURE is a synthetic hydrocarbon resin in solvent. When applied to newly poured concrete FRACURE quickly dries to form a tough, wear resistant film with low water vapour permeability. By reducing the rate of evaporation the water necessary for hydration of cement is maintained in the concrete. During the early curing period this allows the maximum development of compressive and tensile strength and results in more durable finished concrete with lower permeability and less shrinkage.
Under the action of weathering, sunlight and the abrasive action of traffic over the concrete surface, this film will become brittle and dust off after about four weeks exposure and will not then interfere with subsequent coatings.
Resin based curing compounds have lower permeability than P.V.A. emulsion compounds and are therefore more effective. They break down faster than wax based compounds allowing application of subsequent coatings and are less expensive than chlorinated rubber based compounds which use toxic solvent.
