Everflex WPUV Standard (Low Viscosity) - UV Membrane


WPUV is available in 2 versions:

  • WPUV HV - High Viscosity (thicker texture)
  • STD - Standard Low Viscosity version (thinner texture)

Both have the same cured properties.

Everflex WPUV is a rapid drying water-based elastomeric waterproof membrane with micro-fibre reinforcing. It is a single-component liquid membrane designed for various applications, including roofs, planters, and wet areas. Once cured, Everflex WPUV forms a durable, odourless, and seamless waterproof membrane that exceeds the performance standards of AS-4858:2004. Its non-reflective nature makes it suitable for both internal and external use.

Product Characteristics:

  • Colour: Light Grey
  • Size: 15 Litre


  • Wet areas, shower recesses, bathrooms, laundries, and toilets.
  • Patios, terraces, decks, and balconies that require topping, tiling, or coating with trafficable coatings.
  • Concrete slabs above and below grade.
  • Underground tanking and waterproofing.


  • Ready to use - No mixing or dilution required.
  • Rapid drying for earlier tiling.
  • Non-toxic and non-hazardous.
  • Water-based - Easy clean-up with water.
  • Easy to apply.
  • Compatible with all common building materials.
  • Exceeds the standards of AS-4858 and AS-4654.1.
  • High permanent flexibility.
  • Micro-fibre reinforcing for added strength.


  • Do not use if rain is imminent or when temperatures are below 10°C or above 40°C.


Surface Preparation:

  • Ensure all surfaces are structurally sound and free from oils, grease, form release agents, curing compounds, dirt/dust, and any other surface contamination that may hinder adhesion.
  • Achieve a continuous even film build by ensuring surfaces are free from protrusions.
  • Rectify any non-structural cracks, holes, and deformities.
  • Surfaces must be free from surface water and continual dampness.


  • For dusty, very porous, or hot surfaces, it is recommended to use a primer.
  • For internal coatings, use Everflex SBP or Everflex WBP. For external applications such as roof decks, use Everflex VBS (Vapour Barrier System).
  • Refer to the primer application instructions for each specific primer.

Primer Application:

Everflex VBS:

Mix at a 1:1 ratio and apply the primer to porous surfaces at a rate of 5 square meters per litre per coat, ensuring the achievement of a plastic film. Additional coats may be necessary if a plastic film is not achieved.

Everflex WBP:

For internal applications, apply the water-based primer to porous surfaces at a rate of no less than 6 square meters per litre. Allow it to dry before coating with the membrane.

Everflex SBP:

For more difficult surfaces like PVC and waxy surfaces, apply the solvent-based primer at a rate of no less than 9 square meters per litre. Allow it to dry before applying the membrane.


  • Internal: Apply a minimum of two coats to achieve a dry film thickness (DFT) of 0.9mm, following the installation guidelines of AS:3740 Class 3 Membranes.
  • External: Apply a minimum of two coats to achieve a DFT of 1.1mm, following the installation guidelines of AS:4654.2 Class 2 Membranes.
  • Apply the second coat at right angles to the first coat.
  • The average drying time is 2-3 hours at 25°C and 50% humidity.
