Description

Aliphatic, liquid-applied, permanent elastic polyurethane membrane used for long-lasting waterproofing.


Features and benefits:

  • One-component.
  • Solvent based.
  • Ground and air moisture-cured, cold curing.
  • Cold applied.
  • UV stable.
  • Contains a special catalyst that gives fast curing and a blister/defect-free membrane, even at thick layers.
  • The waterproofed surface can be used for light pedestrian traffic.
  • When applied, forms seamless membrane without joints.
  • Resistant to water and frost.
  • Maintains its mechanical properties over a temperature span of -30 to +90®C.
  • Even if the membrane gets mechanically damaged, it can be easily repaired locally within minutes.
  • Provides permanent high level of sun reflectivity contributing to thermal insulation (white only).
  • Certified to EN 1504-2.
  • White or light grey in colour.
  • Crack bridging according to EN 14891.
  • EPD verified.

Coverage

1.4–2.5 kg/m², applied in two or three layers.

Guidance for specification option:

Based on application by roller onto a smooth surface in optimum conditions.

Factors such as surface porosity, temperature and application method can alter consumption. In the case of Mariseal Fabric reinforcement, consumption increases.
