One-component , polyurethane – bitumen liquid membrane for waterproofing
Quick-curing, one-component, thixotropic bitumen-extended
polyurethane fluid. It produces a hydrophobic,
elastic membrane with very strong adhesion to
most types of substrates, as well as bituminous,
and excellent mechanical and chemical resistance properties. It is ideal for application on vertical surfaces: No running, no bubbling.

The material is based on pure elastomeric hydrophobic polyurethane resin and is expanded with chemically polymerized pure bitumen.
Application area
• Cement blocks
• Bitumen-asphalt coil coatings
• Cement or concrete surfaces
• Underground walls and cellars
• Bathrooms and showers (under cladding)

- not recommended for unsound substrates or UV exposed applications.
Features and benefits
Easily applied on vertical surfaces and complex shapes without smudges and formation of bubbles
Excellent practical adhesion to any type of surface, with or without special primers
Excellent thermostability, the product never becomes soft. Maximum operating temperature 80°C
Resistance to cold: the membrane remains flexible even at -40°C
Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance.
Effective humidity barrier
Application procedure
1
Requirements for a concrete base (standard):
• Hardness of concrete: R28 = 15Mpa.
• Concrete humidity: W <10%.
• Temperature: 5-35o C.
• Relative humidity: <85%.

The most suitable primers are: SuperTectum PU Primer or SuperTectum Macro Primer.
2
The substrate must be dry, chemically neutral, even, strong - without cracks and damage, pure - without dust, rust or flaking particles. Cracks, damage, holes must be coated with a suitable material. Traces of contamination from oil, oil substances or chemicals must be removed.
3
Immediately prior to the application, mix with a low speed mixer (300 r/min) the material until a homogeneous mass, while avoiding the penetration of air into the mixture.
4
Apply with a brush or spatula or airless spray. The total consumption of 2.0 kg/m2.
