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.

Specification data - Polyurethane (PUR) waterproof coatings

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). Infrared emittance to ASTM C1371-04a, 0.89 (white only). Solar reflectance to ASTM E903-12, 83 (white only). Shock temperature: 180°C (20 minutes). Rain stability time: 4 hours. Light pedestrian traffic time: 18 hours. Chemical properties: Good resistance against acidic and alkali solutions (5%), detergents, seawater and oils. Guidance for specification option: Time metrics measured at 20°C and 50% relative humidity.
Service temperature	-30°C to +90°C.
