Install the concrete overlay. A stampable concrete overlay should be at least half an inch deep in order to dry without cracking.
Determine whether the weather conditions warrant special treatment for the overlay. Butterfield overlays dry by themselves given enough time. However, if the weather is very hot, the overlay may require misting so that it does not crack as it dries. If the weather is hot, test a small patch of overlay first and mist it with a fine mist from a sprinkler as it dries.
Use a concrete saw to cut joints in the concrete overlay 14 hours after you install the overlay. Install the joints in the same place as the joints that lie underneath the concrete overlay.
Dry the concrete for three days at 70 degrees or higher. After at least 72 hours have passed, cure the dried concrete with a concrete cure and seal product.
Avoid walking on the surface for four hours after you have installed it. Test the surface with a finger and then a foot before walking on it. Wait at least 96 hours before exposing the surface to car traffic, otherwise cracks and changes in shape may occur.
