Mapelastic AquaDefense is a roll-on liquid membrane that can be applied as a thin, continuous barrier to protect adjacent rooms and floors below from water damage. Always apply to difficult to reach areas or problem areas with a brush like coves, corners, cracks and drain. Mapelastic AquaDefense will dry in ideal conditions after about 30 to 50 minutes and, once dried, is ready to receive Mapei polymer or epoxy mortar. AquaDefense can be flood-tested after 12 hours of drying time.
