Planislope RS is a rapid-setting, pre-blended, cement-based, polymer-modified mortar that includes a blend of selected aggregates for use in sloping and thick- bed mortar installations. It only needs mixing with water to produce a mortar of exceptional strength. Used for preparing a substrate before the installation of tile and stone, Planislope RS is designed for pre-sloping under waterproofing membranes and mortar beds in showers when quick turnarounds are desired.
After creating a slope with a fresh mud bed 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 MAPEI's 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 a temperature of 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.
