Professional, Cement-Based Waterproofing Membrane Mapelastic 315 is a trowel-applied, flexible, fiber-mesh-reinforced waterproofing and crack-isolation membrane for installation under ceramic tile or stone on indoor/outdoor residential, commercial and industrial intermittent wet or submerged applications. Mapelastic 315 provides an excellent barrier to prevent water from migrating into other areas. Mapelastic 315 is compatible with any polymer-modified cement-based mortar (ANSI A118.4 or better) or epoxy mortar (ANSI A118.3). Mapelastic 315 exceeds ANSI A118.10 requirements for waterproofing and is IAPMO-listed for use as a shower-pan liner.

  • Dual protection: provides waterproofing and crack isolation
  • Prevents in-plane floor cracks up to 1/16" (1,5 mm) wide from transmitting through tile or stone
  • Compatible with MAPEI’s Fiberglass Mesh and Mapeband ™ accessories
  • Compatible with MAPEI mortars and grouts for complete system protection
  • Eliminates most surface preparation; excellent for smoothing over porous, uneven substrates
  • Durable and flexible; bonds to a wide range of surfaces
  • Install tile or stone after 8- to 12-hour cure.
  • Flood-test after 72-hour cure.
