After treating corners and seams of cement board with mesh tape and a
polymer-modified, cement-based tile mortar, the area should be allowed
to cure for at least 24 hours before the application of MAPEI’s Mapelastic AquaDefense.
Note: If time is an issue, use a MAPEI rapid-set, polymer-modified
mortar with the mesh tape and allow the area to dry for at least four
hours before the application of Mapelastic AquaDefense.
