Why is Mapelastic AquaDefense membrane taking so long to dry?

When applying MAPEI's Mapelastic AquaDefense, it is important to allow it to dry in between coats. It is also important to avoid applying Mapelastic AquaDefense too thick. When applying Mapelastic AquaDefense over a mud bed, the mud bed must be dry before application. After using MAPEI's 4 to 1 Mud Bed Mix, the area should be allowed to cure for at least 24 hours per inch (centimeter) plus one day before application of Mapelastic AquaDefense. For example, if the mud bed is at 2" (5 cm) depth at its highest level, then you must wait three days before the application of Mapelastic AquaDefense. Curing time is based on 73°F (23°C). Cooler temperatures will require longer curing times. If your project is on a fast track, consider Planislope RS mortar, which can receive waterproofing in a matter of hours.
