Product Typification

Cement-bound, watertight and flexible sealant.
Basis : A water-mixed cement powder containing very high amounts of synthetic binders.
Colour : Grey.

Product advantages:
  • 1-component 
  • Watertight 
  • Very elastic 
  • Frost-resistant 
  • Bridges cracks 
  • Suitable for wall and floor 
  • For in- and outdoor use 
  • User friendly


Classification : Highest class in accordance with NEN-EN 14891 CMO2P
Classification : High-grade cement- bound applied in liquid form with watertight membrane for use underneath ceramic tiles with crack spanning quality at low temperatures (-20 °C) and chlorine water resistant. Tested by KIWA Bautest in Dresden, Germany.
Consumption : 

Approx. 1.5 kg/m² per applied 2 mm layer (see instructions). 

Flammability : Non-flammable.
Humidity resistance : Moisture-resistant after drying and as such very suited for application in "wet rooms", outdoors and underwater (swimming pools).
Passableness : Approx 5 hours at 18 - 20 °C.*


  • For the watertight finishing of stony subfloor on balconies and terraces, on which tiles have to be fixed. 
  • For the protection of concrete reinforcement in swimming pools against moisture penetration; also reduces calcium precipitation, for instance. 
  • For sealing stony walls against moisture penetration e.g. in case of heavy used shower rooms.
  • As a separation layer on critical surfaces, such as wood and existing tiles.
  • For gradual drying of freshly poured sand/cement covering floors and to protect them from penetrating moisture. 

Working Process

Tools : Adhesive spreader, fur paint roller, brush (e.g. wall/floor joint) and flat trowel.
Mixing ratio : Add 20 kg 730 Isoflex to 4.5 - 5 litres of water.
Waiting time : Waiting time between two layers is 4-5 hours.
Application temperature : >5 °C.
Processing time : Within 60 minutes after mixing.*
Storage : Store cool and dry in unopened packaging.
Shelf Life : 12 Months, in unopened packaging. After use close the open packaging well.
Drying : 1st layer approx. 4-5 hours and 2nd layer at least 12 hours *
Moisture resistance : Moisture-resistant after drying and as such very suited for application in "wet rooms", outdoors and underwater (swimming pools).

* The mentioned values have been established in our laboratory and must be considered as guidelines in view of possible variations in climatic circumstances, subfloor compositions and layer thickness.


Approx. 1.5 kg/m² per applied 2 mm layer (see instructions). 

  • 730 Isoflex is suitable for stony subfloors that are rigid and have a good tensile and compression strength. The subfloor should also be clean, dry and free from grease and dirt. 
  • Apply 099 Dispersion Primer on stony subfloors e.g. sand/cement screeds. Minimum drying time 1-2 hours. 
  • Pre-fill holes and deep cracks with 923 Europlan Extreme.
  • In advance always seek our technical data sheets. In doubt about the application ask for technical advice. 

User manual:
  • Add 20 kg of 730 Isoflex to 5-6 litres of cool and clean tap water and stir the mortar thoroughly for 4 minutes by using an electric stirrer (approx. 1.000 rpm), to a smooth and homogeneous mixture. 
  • Apply the first layer with a 4x4 mm notched spreader on the subfloor. Smooth the strips with a lambswool roller until an impervious layer arises. The lambswool roller should be light humid.
  • After a sufficient drying time (4-5 hours depending on the climatological circumstances) apply the second layer, according to the first layer (minimum drying time second layer is 12 hours).
  • Under no circumstances apply more than 2 mm per layer.  
  • The 2 layers of 730 Isoflex need to total at least 2.5 to 3 mm when dry.
  • Protect the complete surface from applying the 730 Isoflex to setting the final layer against negative weather influences, such as moisture penetration, frost, etc. 
  • Preferably glue ceramic tiles with our 733 Superior S2 or 705 Special Adhesive.
  • Before tiling make the surface dust free.
