AU-1 is a professional-grade, elastomeric acrylic urethane sealant engineered for demanding commercial and industrial applications. Designed for extreme durability and flexibility, AU-1 delivers long-lasting performance in high-movement joints and harsh environments.
Formulated with advanced Aqueous Polyurethane Dispersion (PUD) technology, AU-1 bonds at the molecular level to most construction materials—without the need for mixing or priming. Its smooth, non-sag formula makes application clean and efficient, saving time on the jobsite.
Once cured, AU-1 remains highly elastic while providing exceptional resistance to UV exposure, aging, mold, and mildew. It’s fully paintable, will not bleed through finishes, and resists dirt pickup—ensuring a clean, professional appearance for years to come.
VOC compliant nationwide (including CARB and SCAQMD), AU-1 performs reliably in all climates and maintains flexibility under continuous, varying mechanical stress.
Key Features & Benefits
Industry-leading durability for long-term performance
Outstanding UV & weather resistance in all climates
Handles extreme joint movement without cracking or failing
Seals vertical and horizontal joints up to 2” wide
No priming required for most substrates
Fully paintable — no bleed-through or tacky finish
50% joint movement capability (±25%)
800% elongation for maximum flexibility
Simplified application & cleanup to reduce labor time
