Rapid screed

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
