  • Screed of up to 8mm can be laid in single operation. Trowel marks and high spots can be removed with coarse sandpaper of a corundum stone when the screed is dry.
  • Depending on the weather conditions, it is advised to add a light spray of water on the product to ensure there is enough water for the hydration reaction.
  • Drying times vary from 30 minutes upwards, depending upon thickness if the screed and atmospheric conditions.
