Neoproof PU W -40



Water based  polyurethane,  waterproofing  coating  for  roofs  when  mechanical durability and outstanding waterproofing properties are required. It forms a non-penetrating against moisture film with resistance to UV and mechanical stress.  

Fields of application

  • Roofs made of concrete, cement boards, mosaic, cement slurries
  • Rooftops with resistance to stagnant water
  • Metallic  surfaces  after  the  application  of  the  proper  primer(Vinyfix Primer or Silatex Primer)
  • New or old acrylic or polyurethane waterproofing layers
  • Mineral bitumen membranes where the low temperature flexibility from -10oC down to -40oC is needed.
(Upon some surfaces above, it is necessary to prime them with
the appropriate each time primer, before Neoproof® PU W-40 application)


  • Ideal solution for waterproofing walkable roofs
  • High mechanical strength
  • Applicability  and on cloudy  days as the  final  polymerization  of  the material is done by evaporation, and therefore under shading
  • No appearance of holes in the surface during the curing of material
  • Protection of polyurethane foam insulation
  • Eco-friendly (Water-based)
  • Easy to apply
  • Resistant to temperatures from -40oC to +80oC
