- 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
O1 evaporation protection
after-care of concrete in accordance with TL NBM-StB 09 for a more even and slower drying of concrete, mortar and screed
- 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
