The membrane is suitable for use with all ADEX exterior insulation and finish system (EIFS) installations and ADEX STANDARD MESH is embedded into the membrane to help dictate proper thickness.

  • Trowel-applied.
  • Mixed with Portland cement.
  • Optional layer of embedded mesh to gauge proper application thickness.
  • Vapour Resisting Barrier (low permeability).
  • Air and Moisture Barrier Component.
  • Can be installed underneath a variety of wall claddings.
  • Suitable above-grade substrates:
    • Exterior grade gypsum board,
    • Glass-mat faced gypsum board,
    • Concrete or masonry walls.
