A low-pressure, sprayed-applied, 100% solids, flexible, two-component, rapid curing, pure polyurea system, designed as a waterproofing and protective coating for small areas including repair work, on concrete and steel surfaces. It combines the advantages of a seamless coating with long life cycle and high durability.


  • Environment friendly.
  • Spray applied at low pressure: No need for specialist polyurea hot spray apparatus.
  • Can be pour-applied with manual equipment.
  • Excellent chemical resistance, thermal stability and UV resistance.
  • Very fast turn-around time: coated substrate or repair can be put into service within an hour.
  • Seamless and monolithic, including field joints.
  • Significantly enhances the durability of reinforced concrete.
  • Colour stable when coated with Nitoproof UVR Topcoat.
  • Can be applied at ambient temperatures from 5–70°C.
