Number 2. Big Stretch Acrylic Latex Exterior Caulk. The Sashco 10016 is commonly referred to as the Big Stretch. This is one of the caulks that is versatile and can be used for both exterior and interior applications.

Besides the Big Stretch caulk is also great for soundproofing. Big Stretch comes in a 10.5-ounce tube and is 100% acrylic latex. That is why it has high elasticity, giving it room to stretch to up 500% without cracking. It forms quite a strong adhesion, as long as the environment permits.
