AU-1 is a premium, highly elastic, and non-sagging construction sealant designed for lasting performance across residential, commercial, and industrial applications.
Ideal for expansion and control joints, concrete panel and tilt-wall joints, precast units, EIFS, and sealing windows, doors, and siding. It bonds directly to concrete, masonry, stucco, glass, metal, building wraps, fascia, and flashing.
With exceptional resistance to aging, AU-1 provides enduring protection without mixing or priming, bonding at the molecular level to most construction materials. Paintable and resistant to bleed-through, AU-1 ensures a flawless finish that resists dirt buildup and remains tack-free.
Once cured, it's also exceptionally resistant to mold, mildew, and UV exposure, maintaining its elasticity and adhesion through years of varied climate conditions. Fully VOC-compliant nationwide, including stringent CARB and SCAQMD standards, AU-1 is built to endure, never losing flexibility under dynamic mechanical stress.
