Acrylic Based Wet Room Waterproofing

ISONEM DF 9 is a single component acrylic polymer-based and elastomeric resin-based waterproofing material. It does not contain solvent. By drying on the applied surface, it forms a jointless and waterproof elastic coating. The coating is resistant to mechanical strength.

ISONEM DF 9 with high crack bridging capacity, can be adhered onto any surface with the appropriate adhesive. It is adhered perfectly to many surfaces such as metal, plastic, wood, concrete, screed etc. Thus, it insulates floors, water outlets, pipes extremely safe.

Application Instructions

  • The application surfaces must be dry or slightly moist and clean
  • The surface repairs and preparation prior to the insulation must be completed on the application surfaces
  • In junctions of walls and bases, 45 gr/m2 insulation mesh reinforces must be used
  • ISONEM DF 9 is ready to use but must be well mixed before use
  • If there are materials preventing the adhesion such as dust, dirt etc, ISONEM UNIVERSEL PRIMER, must be applied on the sub-floor.



ISONEM DF 9 is applied in two layers for 4 hours of intervals without dilution by brush. Surface should be protected for 4 hours against water after application. Application shouldn’t be done under 5°C and wet or frozen surfaces.

NOTE: During and after the application surfaces should be protected from rain, water, mechanical loads and impacts for 24 hours.
