Guide to Concrete Curing Time & Methods

When concrete is first placed for a slab, bleed water rises as the concrete mixture settles. During this period (initial set), if the bleed water is evaporating from the surface faster than it is rising out of the concrete then you need to do some initial curing or else you are likely to end up with plastic shrinkage cracks.

Curing Concrete Dos and Don'ts

One of the most common methods for curing concrete is to hose it down frequently with water—five to 10 times per day, or as often as you can—for the first seven days. Known as "moist curing," this allows the moisture in the concrete to evaporate slowly. Moist-cured concrete can be up to 50 percent stronger than co…
