U-Coat 850

LC-Technology - Liquid-applied polyurethane waterproofing membrane

U-Coat 850 is a premium, liquid and cold applied, one-part polyurethane waterproofing membrane. It cures by reaction with ambient moisture to form a strong protective and self-leveling base coat. Non sagging, it’sdeal for application on concrete and waterproof of floor, wall and corners. Compliant to: LEED iEQc 4.1 ; SCAQMD Rule 1168 ; BAAQMD Reg 8 Rule 51
  • Waterproofing of wet areas (under-tile) in bathrooms, kitchens, balconies, auxiliary rooms, etc
  • Waterproofing in new or existing concrete floor slabs and roofs
  • Liquid: easy to apply with professional or simple tools, like brush or roller
  • Full surface adhesion and seamless covering, even on curved surfaces
