TriSeam
Sprayable Seam Sealer with Built-In Fiber Reinforcement
TriSeam is a single-component, fiber-reinforced acrylic seam sealer engineered for flexibility, ease of application, and long-term durability. Designed to eliminate the need for embedded fabric at seams, it creates a waterproof, crack-resistant seal that expands and contracts with the roof—ideal for preparing surfaces for NanoTech’s Cool Roof and All Weather systems.
Sprayable, brushable, and roller-applied, TriSeam reduces labor time while delivering superior chemical resistance and adhesion. Within 24 hours, it’s ready for top coating—making it a seamless, time-saving solution for commercial roof restoration.
