Sashco Cartridge Big Stretch Caulk Steel - 10.5oz

Homes move. Window frames move away from the siding or doors shift against the brick. This movement happens as the home settles as well as with temperature changes and even wind. If movement causes a sealant to crack, you can lose the air or moisture barrier in your home. That’s why you need Big Stretch®. With powerful adhesion and extreme elasticity, it will stick, twist, bend, compress, and stretch — 530% maximum stretch — to handle most any movement your home can dish out, all without cracking.
