Starflex Ultra is a family of special single-component liquid membranes for waterproofing. Ultra’s advanced technology ensures quick and easy application, has excellent resistance and elasticity properties, and guarantees a final result that lasts up to 30 years.

The MPM research and development department has designed this solution as a response to the industry’s main challenges, and has also developed a B-roof fire-certified version. 

  • STARFLEX MONO: Polyurethane-based membrane, designed specifically for application to old surfaces
  • STARFLEX ULTRA: Polyurea – polyurethane based membrane, designed specifically for application to old surfaces
  • STARFLEX ULTRA FR: Polyurea – polyurethane based membrane, for fire-certified waterproofing

Bicomponent hot systems

STARFLEX HR is the family of hot, bicomponent polyurethane waterproofing systems. Its main characteristics: high elasticity, rapid hardening and the possibility of application on new or existing surfaces, make the system ideal for waterproofing and protecting roofs, car parks and other types of infrastructure.

STARFLEX HR brings together a complete range of polyurea-based systems to meet the most stringent technical specifications for waterproofing:

  • STARFLEX HR: Pure polyurea-based membrane, specific for driveways or continuous immersion systems
  • STARFLEX HR-S: Pure polyurea-based membrane, designed specifically for application to old surfaces
  • STARFLEX HR-E: Hybrid polyurea-based membrane, designed specifically for application to old surfaces
  • STARFLEX HR-FR: Pure polyurea-based membrane, specific for fire-certified waterproofing

MPM delivers solutions for every roof type

Concrete and fibre-cement roofs

Concrete and fibre-cement structures demand strong adhesion and flexibility.
Our liquid flat roof systems provide a continuous membrane that bridges cracks and resists standing water. With outstanding elasticity and chemical resistance, Starflex membranes protect the substrate and extend the roof’s service life — even under the harshest conditions.

Suggested systems:
STARFLEX HR • STARFLEX ULTRA • STARFLEX ULTRA FR

 

Bituminous membrane roofs

Old bituminous membranes often suffer from cracks, blisters, and detachment.
MPM’s cold applied roofing systems restore these surfaces without removal, saving time and cost. The result: a reinforced, UV-resistant, and fully weatherproof roofing system ready to face any season.

Suggested systems:
STARFLEX MONO • STARFLEX HR-S • STARFLEX HR-E

 

PVC and TPO roofs

Modern synthetic membranes require high-adhesion coatings to ensure watertight performance.
Our liquid membrane roofing systems form a continuous barrier over PVC or TPO surfaces, resisting movement, temperature fluctuations, and ultraviolet exposure. The result is a liquid roof waterproofing system with long-term stability and easy maintenance.

Suggested systems:
STARFLEX ULTRA • STARFLEX ULTRA FR

 

Metal roofs

Metal roofs expand, contract, and corrode under weather stress.
Starflex roof deck waterproofing systems are designed to prevent oxidation, seal joints and fasteners, and maintain elasticity over time. The liquid membrane creates a smooth, reflective finish that reduces heat absorption and ensures watertight integrity — even on complex geometries.

Suggested systems:
STARFLEX MONO • STARFLEX HR-S • STARFLEX HR-E
