(Also see Waterproofing)
A liquid waterproofing membrane such as MAPEI Mapelastic AquaDefense can often be used as a replacement for a PVC liner. When using a liquid waterproofing membrane such as 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 Type 1 mastic and premixed mortars like MAPEI Premium Mortar for tile and stone should never be used over liquid waterproofing membranes.
