O1 dehydration protection

after-care of concrete in accordance with TL NBM-StB 09 for a more even and slower drying of concrete, mortar and screed

  • forms a protection film, to great extent impermeable to water vapour
  • increases firmness near the surface and increases significantly the durability
  • reduces the risk of swelling cracks, flaking and sanding, which result mostly because of drying too early
  • dissolves only very slowly under weathering
  • consumption: about 100–150 g/m²
  • barrier coefficient: 85 %
  • density: 0,99 g/cm³
  • colour: white

properties

  • protects surfaces against premature loss of humidity
  • provides a more even and slow drying of concrete, mortar or screed over 3 to 4 weeks
  • forms a protection film, to great extent impermeable to water vapour, that dissipates slowly through weathering
  • increases firmness near the surface and increases significantly the durability
  • hinders both early shrinkage due to drying and premature drying, which minimises residual "surface sand"
  • under normal climate conditions, it does not need further care or concrete proofing

fields of application

  • concrete roadways
  • mortar surfaces
  • cement screeds
  • concrete blocks and prefabricated parts
