DAP Polyurethane Construction Sealant is a premium one-part, moisture-curing polyurethane adhesive sealant in a 10.1 fl oz cartridge. This commercial-grade sealant provides long-lasting flexibility and durability for sealing exterior gaps, joints, and cracks. The gray formulation meets ASTM C920 Class 35 standards for elastomeric joint sealants.
This non-sag formula cures by reacting with moisture in the air to form a waterproof, elastic seal. The sealant offers high joint movement capability, making it ideal for construction applications where thermal expansion and contraction occur. Once cured, it maintains flexibility while providing excellent adhesion to most building materials including concrete, wood, metal, and masonry.
Perfect for commercial construction, exterior building envelope sealing, and weatherproofing applications. Works well for sealing around windows, doors, expansion joints, and other building penetrations where a durable, weather-resistant seal is required. The 10.1 fl oz cartridge fits standard caulk guns for easy application.
