High-performance, water-based sealant stretches to more than 500% of its original size to stick always and crack never
Homes move. Window frames pull away from the siding, or doors shift against the brick. They move when the temperature changes, the rain falls, the wind blows, or the earth quakes. Most caulks can’t take it – they dry hard and crack. That’s why you need Big Stretch high-performance water-based sealant. Its powerful adhesion and extreme elasticity will stick, twist, bend, compress, and stretch – more than 500% of its original size! – to handle most any movement your home can dish out, all without cracking.
Won't crack...it just stretches
Keep the weather out
Thanks to its extreme elasticity, Big Stretch can twist, bend, compress, and stretch with the movements of your home to create a permanently waterproof seal. Handles even the widest joints with no slump.

You’ll love Big Stretch. You can smooth it on as easy as mayo on a BLT. It’s low odor and easy water clean up. It comes in a variety of colors, including clear, or it is easily painted. What’s not to like?
