Notice

Shelf life of 9 months when protected from the weather


Seal any opened containers immediately, store in a cool and dry location on wooden grids and use up as soon as possible.



The screed can be walked on after 3 hours.


The rapid screed can be covered with concrete at a residual moisture content of less than 2.5 wt % (measured according to the CM method). This residual moisture content is achieved after 24 hours with a screed thickness of 4 cm, a substrate and air temperature above +20°C and a relative humidity of max. 50 %.



In the case of a compound screed, you must wait until the complete structure is dry.


For heated screeds, heating can take place after three days:


  • The flow temperature should be kept at the lowest level for three days. Then increase the heat in 5°C steps until the maximum flow temperature is reached.

  • Maintain this temperature for four days and then lower it to room temperature (approx. 20°C) in 5°C steps.


  • The technical data applies to +20°C and 50 % relative humidity

  • Lower temperatures increase the specified values, while higher temperatures decrease the specified values

  • Screeds interact with their environment with regard to building physics. If the screeds remain in place for an extended period of time, moisture can penetrate back through them

  • The amount of water required is based on empirical values. Depending on the application, it may be necessary to add more water

  • The processing time depends on the absorption capacity of the substrate

  • For the subsequent laying of tiles, slabs, mosaic, concrete, building blocks or natural stone coverings

  • In the case of unusually highly absorbent, new or unusual substrates, test surfaces must be prepared and the processing guidelines of the respective manufacturer followed

  • Clean vessels, tools etc. immediately with water


Once hardened, it can only be cleaned off mechanically

The usage instructions are recommendations based on the tests we have conducted and on our experience; carry out your own tests before each application.
