Mapelastic WaterStop

Waterproofing and Crack-Isolation Membrane

Mapelastic WaterStop is a flexible, thin, fast-drying, one-component, liquid-rubber waterproofing and crack-isolation membrane for installation under ceramic tile or stone in residential, commercial and industrial environments. It provides a continuous barrier to protect adjacent floors and rooms below from water damage. Mapelastic WaterStop also prevents in-plane floor cracks (up to 1/8" [3 mm]) from transmitting through tile or stone. In problem areas such as coves, corners, cracks and drains, it can be combined with MAPEI’s optional Reinforcing Fabric or Mapeband™ accessories (cove roll and drain flashing) to provide additional protection.

  • Fast-drying: Install tile after 60 to 90 minutes of drying time.
  • Flood-test as a shower-pan liner after 12 hours of drying time.
  • Easy to apply with roller or brush; water cleanup
  • 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
