DAP Extreme Stretch Clear is a high performance acrylic urethane elastomeric sealant for sealing a wide range of interior and exterior surfaces - windows, doors, trim, molding, siding, soffits, corner joints, countertops, sinks, pipes, vents and ducts. It stretches over 600% so the seal stays crackproof through expansion and contraction, and creates a waterproof, weatherproof seal.

For best results: Apply between 40F and 100F, and not when rain or freezing temperatures are forecast within 24 hours. Cooler temperatures and higher humidity slow drying. Priming is not usually necessary, but substrates that stay constantly damp after cure may need it - test one joint first. Cut the nozzle at a 45 degree angle to the bead size you want, and tool the bead before it skins over. Not for continuous underwater use, filling butt joints, surface defects or tuck-pointing.
