As a result, surface cracking may occur, especially if the stresses develop before the concrete attains adequate tensile strength. As a rule of thumb, ordinary concrete should generally be allowed to cure for 24 hours before allowing general foot traffic, and several days. This is known as “moist curing” and allows the moisture in the concrete to evaporate slowly.
In the winter, the newly poured concrete steps will take longer to cure due to the damp, cold weather. Rain will not damage concrete if it’s four to eight hours after being poured. On average, you might have to wait anywhere from one to six hours for the compound to cure.
