Sikaflex Construction Sealant, White Paintable, All Purpose Polyurethane Used to Seal Joints and Gaps, 10.1 fl. oz Cartridge

This one-component, non-sag sealant is the choice for professional-grade quality while requiring only beginner-level DIY skills. It's also elastomeric, which gives the paste a rubbery texture and enables your joints to adjust without cracking or breaking. Seal windows and door perimeters, and fill gaps in walls, trim, flashing, and more. It's resistant to aging and weathering, so the Sikaflex white caulk always looks its best. It's both waterproof and water immersible, enabling use in moisture-heavy environments. The final cure is complete in about a week, depending on atmospheric conditions.
