It can be combined with Mapeis optional Reinforcing Fabric or Mapeband accessories (cove roll and drain flash) to provide additional protection.

Mapelastic AquaDefense can be flood-tested after 12 hours of drying time, is IAPMO-listed for use as a shower-pan liner, and exceeds ANSI A118.10 and ANSI A118.12 standards.
