Portland Cement Drying Time

Cement dries in stages that take about 30 days to complete. It takes one to two days for cement to dry enough for people to walk on and five to seven days before people can drive on it. The weather has a large effect on how quickly cement completes the curing process. Factors such as rainfall, sunlight, wind and humidity are all contributors.
