DO spray new concrete with water. 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.
Should you cover fresh concrete with plastic?
Covering the curing concrete with plastic keeps it cleaner, but there is a more important purpose behind this practice. Water is mixed into concrete to activate the cement binding agent and as the mix dries, it hardens. The drying, or “curing,” should be gradual, otherwise cracking may occur.
