Neoproof PU W is the ideal solution for waterproofing walkable roofs and difficult points on any building surface with high mechanical strength. It is easily applied even on cloudy days, as the final polymerization of the material is done by evaporation, and therefore under shading conditions. It is a waterproofing material with high resistance to severe weather phenomena.


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 Neotex® Metal Primer )

  • New or old acrylic or polyurethane waterproofing layers

(Upon some surfaces above, it is necessary to prime them with the appropriate each time primer, before Neoproof® PU W application)

Application Steps

  • Initially, surface preparation is required. The substrate should be clean, dry and free from dust, oil, grease, or any poorly adhering material. 

  • Upon some surfaces above, it is necessary to prime them with the appropriate each time primer, before Neoproof® PU W application. It is advisable to prime the surface with Revinex® diluted with water in ratio Revinex®:water-1:4, in order to seal any pores, fix the surface, and thus obtain stronger adhesion and higher coverage or Silatex® Primer diluted 30% with solvent Neotex 1111.

  • Then, the product can be applied. Stir the product thoroughly in its container. After priming, apply at least two layers of Neoproof® PU W using a brush or a roller, each time working the material in a vertical or different direction to that of the previous coat. Dilute with 5% water for the first coat. Apply the second coat after 24 hours, without thinning. Follow the above directions to the third layer.

  • For demanding applications or when covering cracks bigger than 1,5 mm, Neoproof® PU W may be reinforced with specially designed non-woven polyester tissue Neotextile®. In such cases, at least three coats of the product are required.
