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.
