Allpro's Pro Stretch Caulk is a flexible, acrylic urethane sealant. The sealant is capable of spanning up to 2" with a 50% total joint movement. Even when it expands and contracts, the sealant is airtight and water resistant. While the caulk is white, it can also be painted once cured.
🏆 Pro Stretch is our favourite interior and exterior caulking. Use on surfaces such as baseboard and crown molding, windows, and doors.
