Fabriseal
Sprayable Seam Sealer with Built-In Fiber Reinforcement
Fabriseal is a single-component, fiber-reinforced acrylic seam sealer designed to create durable, flexible seals over joints, fasteners, and penetrations on commercial roofing systems. This sprayable solution combines the strength of embedded fibers with the convenience of a water-based acrylic formula, eliminating the need for separate fabric reinforcement.
Engineered for efficiency and long-term performance, Fabriseal bonds tenaciously to a variety of substrates while maintaining exceptional flexibility through thermal cycles and building movement. Its advanced polymer technology ensures superior adhesion and weather resistance, making it the ideal choice for sealing critical roof details that demand both strength and elasticity.
