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.

Third-party certification | Environmental Product Declaration (EPD), registration number S-P-07978. |
Colour | White.Light grey |
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. |
Elongation at break | To ASTM D412/ DIN 52455, >160%. |
Tensile strength | To ASTM D412/ DIN 52455, >8 N/mm². |
Water vapour permeability | To EN ISO 7783:2012, 13.84 g/m²/day. |
Adhesion to concrete | To EN 1542, >2 N/mm² (concrete surface failure). |
Shore A hardness | To ASTM D2240 (15"), >80. |
Final curing time | Seven days (at 20°C, 50% relative humidity). |
Performance characteristics | Solar reflectance index (SRI) to ATSM E1980-01, 104 (white only). Guidance for specification option: Time metrics measured at 20°C and 50% relative humidity. |
Service temperature | -30°C to +90°C. |
