EcoFin Pro Polyurethane Liquid Waterproofing – Grey 15kg. High-Performance Flat Roof & Balcony Coating
EcoFin Pro PU Waterproofing – 15kg (Grey) is a premium-grade polyurethane liquid membrane system, specially designed to provide long-lasting, seamless waterproofing for both new and existing surfaces. Ideal for flat roofs, balconies, terraces, walkways and gutters, this high-performance solution offers exceptional versatility, durability, and ease of application.
This single-component liquid membrane adheres to most substrates without the need for a primer – only surfaces like concrete, TPO, and EPDM membranes require one. Simply apply using a resin roller for a smooth, watertight finish.
EcoFin PU is part of a wet-on-wet system, allowing the base coats and EcoFin Reinforcement Matting to be laid without waiting for each layer to cure. Once the base layers have cured, apply EcoFin Protect (topcoat) within 48 hours to ensure long-term UV protection and a finish that lasts 25+ years. Installed to specification, the system is covered by a 20-year manufacturer materials guarantee.
Tested and certified to the highest standards, including BBA approval, EcoFin PU is your go-to solution for professional-grade waterproofing.
