Product Overview
UF90 GacoMastic is a fiber‐reinforced mastic product for use on details and seams. It eliminates the need for three‐coarse applications with embedded fabric, thus significantly reducing installation time. This single‐component mastic also has a higher viscosity and sag to conform around details and in vertical applications. The Gaco U9 Series is a single‐component, liquid‐applied waterproof urethane roof system consisting of three products. The UF90 GacoMastic reinforced urethane mastic for seams, penetrations, and detail work, the U91(C) Aromatic Urethane base coat, and the U92 Aliphatic Urethane top coat. Gaco Urethane Coatings offer the best combination of durability, tensile strength, and versatility. Expect excellent protection from UV, moisture, extreme weather, and foot traffic. Combining the U92 Aliphatic Urethane top coat with the U91 Aromatic Urethane base coat provides maximum durability and reflectivity for long life and improved energy efficiency.
