Sashco 10.5 oz. Black Acrylic Interior and Exterior Caulk

Big Stretch is a high-performance water-based elastomeric sealant with powerful adhesion and excellent elasticity. It spans gaps and stretches significantly without cracking, providing a reliable, long-lasting seal that accommodates structural movement. Designed for both interior and exterior applications, this caulk stays soft and pliable over time to prevent brittleness. It adheres securely to difficult building materials like vinyl siding and windows, cleans up easily with water, and can be painted over for a professional finish.
