Big Stretch Elastomeric Caulk 10.5 oz (Woodtone)

Big Stretch Elastomeric Caulk is a premium water-based acrylic sealant designed to stretch and flex with your home’s natural movements—never drying hard or cracking. Its powerful adhesion and extreme elasticity ensure a permanently waterproof seal on wood, windows, doors, and more. Whether you’re sealing siding gaps, trim joints, or crown molding inside and out, this 10.5 oz cartridge delivers professional results with easy water cleanup and paintability for a perfectly finished look.

Built to withstand temperature swings, moisture, and joint movement, Big Stretch keeps the weather outside where it belongs. Apply it like a pro, smooth it to seal any gap up to 2″ wide, then paint or stain over it once it skins over. With up to 500 % elongation and a 5-day full cure time, this elastomeric caulk stays supple, watertight, and durable for years of maintenance-free performance.
