(Also see Waterproofing)
A liquid waterproofing membrane such as MAPEI’s Mapelastic AquaDefense can often be used as a replacement for a PVC liner. When using a liquid waterproofing membrane such as MAPEI’s Mapelastic AquaDefense, it is important to follow all instructions on the label and Technical Data Sheet as well as local building codes.
Note: Premixed adhesives like MAPEI’s Type 1 mastic and premixed mortars like MAPEI’s Premium Mortar for tile and stone should never be used over liquid waterproofing membranes.
