Mapelastic AquaDefense Waterproofing Membrane - 1 Gallon

Mapei's Mapelastic Aquadefense is a pre-mixed liquid-rubber waterproofing and crack-isolation membrane that can be easily applied before installing tile or stone in residential and commercial applications. This quick-drying membrane provides a thin, continuous barrier that protects adjacent areas from water damage.

  • Time-saving: Flood-test as shower-pan liner after 12 hours of drying time
  • Apply with roller or brush – easy to install over flat, curved or irregular surfaces
  • Approximate coverage - 60 sq. ft. (5.57 m²)
  • Bonds to a wide range of surfaces; convenient, user-friendly and versatile
  • No odor; great for confined spaces
  • Prevents in-plane floor cracks from transmitting through tile or stone
