Uraflex 360 / 375UV Balcony Waterproofing System
Polyurethane Elastomeric Traffic Bearing Waterproofing System for Balconies & UV Exposed Pedestrian Surfaces
Description

Uraflex 360/375 UV Polyurethane Elastomeric Traffic Bearing Waterproofing System is a solvent free, high-performance deck coating system for balconies and pedestrian traffic subject to UV exposure. The system consists of an elastomeric membrane base coat, Uraflex 360 and an abrasion, UV-resistant topcoat, Uraflex 375 UV. Uraflex 360/375 UV is a UV-resistant, traffic bearing protective waterproofing system which is aesthetically pleasing, resistant to dirt pick-up and is easy to clean

Advantages
  • Abrasion resistant and elastomeric
  • Non-skid and decorative
  • Waterproof
  • Potential LEED Credits
  • Solvent free; minimal disturbance to tenants
  • UV resistant, durable and long-lasting
  • Easy to clean
  • Protects from hairline cracks

 

Uses

Uraflex 360/375 UV is intended for use as a protective waterproofing pedestrian deck coating system for concrete, exterior grade plywood, and metal surfaces. It is ideal for balconies, plazas, decks and roof terraces.
