How to cure concrete pad

Select the best curing method based on the mix design of your concrete. For example, concrete with a water-to-cement ratio below 0.40 is typically wet-cured. Begin curing the concrete pad immediately after finishing the pad has been completed. Wet the concrete surface with water. Use a protective covering that retains moisture or water, such as plastic or burlap. Burlap may need re-wetting. Cover the concrete pad with the protective covering. Generously overlap the protective covering at the joints. Use cement blocks or pieces of lumber to anchor the protective covering. Tape the joints so the wind cannot lift the covering.

Guard against excessive temperatures, humidity and wind. These conditions will affect the end result. Leave formwork in place, as it can help prevent moisture loss. Moisten wood formwork in hot temperatures.

Leave the protective covering in place according to specifications or general industry practices -- three to seven days for small projects; two weeks for larger projects. Different mix designs, size of concrete pad or desired strength will determine how long you should cure your concrete pad. Monitor the concrete surface and protective coverings during the entire curing time to prevent dry spots in the concrete or displacement of the protective coverings.
