How long should new concrete be kept dry?

New concrete should typically be kept dry for at least the first 24 to 48 hours after pouring to allow for proper curing. However, it's essential to maintain moisture for a longer period—ideally, up to 7 days—for optimal strength development. During this time, you can cover the concrete with wet burlap, plastic sheeting, or use curing compounds to prevent premature drying. Proper curing is crucial for achieving the desired durability and performance of the concrete.
