In a few hours, the wall will be finished.

It takes about 24 hours for the first time and about two days for the second time.

According to the Qi family. It takes about 24 hours for the first wall to dry. If the temperature is low and the humidity is high, the drying time will be doubled. When the first wall is completely dry, you can brush the soil for the second time. However, the drying time of the second wall will still be affected by the thickness and climate. If the weather conditions are good, it will dry in about two days.
