IZOTEX MASTER Waterproofing Membrane Download Document


Durable three layers waterproofing and vapour retardant membrane consisting of PP/PE/PP layers. It protects floor and wall substrates from water penetration and moisture passage in wet areas.


  • MASTER protects the substrate from the water leakage that comes from the joint gap, crack or fracture of the covering material.
  • The special fleece lining on both sides makes the membrane compatible with all kinds of adhesive except solvent based adhesives.
  • MASTER can be used in both indoors and outdoors.
  • Due to its flexible structure there will be no crack on the membrane in time.
  • The membrane forms an optimum surface for tiling after its installation.
  • It does not pose risks in terms of worker health and work safety during the application.
  • It is easy to work with, it can be cut by craft knife or scissors.

IZOTEX MASTER Waterproofing Membrane


MASTER is used to provide waterproofing and damp proofing beneath ceramic tiles on wet room’s floors and walls. The membrane is used to ensure waterproofing under covering materials (such as marble, covering concrete etc.) on terraces.

MASTER is used as moisture barrier beneath floor heating systems to prevent moisture comes from the substrate and to block the vapor formation.
