Sashco Big Stretch® High-Performance Caulk

Stop cracks before they start. Sashco Big Stretch® is a premium elastomeric acrylic latex caulk designed to move with your home as it expands, contracts, and settles. Unlike ordinary caulks that dry hard and crack, Big Stretch stretches and compresses with changing conditions, creating a long-lasting, weather-resistant seal around windows, doors, siding, trim, and more. With powerful adhesion, paintable finish, and easy water cleanup, it’s a favorite among professional contractors and DIY homeowners alike. Big Stretch can stretch up to 500% of its original size while maintaining a durable seal.
