Big Stretch ALMOND case of (12) tubes of 10.5 oz
The window frame moves away from the siding or the door shifts against the brick. Most caulks can't take it - they dry hard and crack out.
That's why you need Big Stretch. It works when other caulks fail. It has powerful adhesion but stays elastic and rubbery. It will twist, bend, stretch and compress to absorb just about any movement a home can dish out.
