Caulks & Sealants
Our caulks and sealants deliver durable, airtight, and water-resistant seals for construction professionals. Formulated with advanced acrylic, siliconized, and hybrid technologies, they resist cracking, mildew, and UV degradation. Ideal for windows, doors, siding, and expansion joints, these products ensure long-term performance with warranties up to 60 years.
Elastomeric Patching Compound
Designed for repairing cracks in concrete, stucco, brick, and EIFS systems, our elastomeric patching compounds offer 300-800% elongation and strong adhesion. Available in smooth or textured finishes, they provide permanent, paintable repairs for both interior and exterior applications.

Our hybrid sealants combine STPE technology with fast curing and flexibility for extreme weather conditions. They adhere to substrates like Kynar, aluminum, and concrete without priming, making them ideal for expansion joints, waterproofing, and building envelope sealing in challenging climates.
Liquid Applied Barrier
AU-1 LAB is a liquid-applied air and water barrier that forms a breathable, waterproof membrane. It adheres to green concrete, stucco, and EIFS systems, offering UV resistance and easy application via brush, roller, or sprayer for up to six months of weather exposure.
Concrete Repair Sealant
Textured masonry repair sealants restore horizontal surfaces like driveways and patios with flexibility and low shrinkage. Paintable and durable, they bond to concrete, grout, and EIFS systems, ensuring long-lasting repairs for both interior and exterior use.
