Methods of Curing Repaired Concrete Works

To keep repaired surfaces wet for the initial curing, water should be applied at regular intervals by a large brush or spraying device.

Damp hessian may be used or wet burlap pads can be used.

In some cases it may be difficult to hold damp hessian or wet burlap pads in position. In such a case a membrane curing compound is best suited. Best results are obtained by initial curing with water followed by sealing compound, when concrete surface is still damp.

Deliquescent salts such as calcium chloride may be used to hasten hardening and help to keep the patch in moist condition.

Horizontal surfaces can be cured by spraying method or by placing wet gunny bags.
