One Sealant, Multiple Solutions
Imagine a sealant that's as versatile as it is reliable. Bostik 915 is designed to tackle a wide range of applications, from foundation to finish. Whether you're sealing expansion and control joints, securing tilt-up joints, or installing perimeters around doors, windows, and other wall penetrations, Bostik 915 delivers tenacious sealing and bonding performance every time.

Unmatched Flexibility and Durability
Picture this: A sealant that cures to a tough yet flexible rubber, capable of dynamic joint movement that totals 70% of the original joint geometry plus minus 35%. This means less worry about cracks or leaks over time. Bostik 915 stands strong in the face of extreme temperatures, with a cured performance range of -40°F to 150°F, ensuring your projects are secure through the harshest of winters and the hottest of summers.

All-Season Performance
With its all-season formula, Bostik 915 remains stable over time, providing consistent results regardless of the environmental conditions. This reliability is essential for projects that need to stand the test of time and the elements.

Broad Compatibility
Whether you're working with stone, foam, masonry, ceramic, wood, steel, Kynar coated metals, copper, or most other metals, Bostik 915 forms a durable, flexible bond. It's ideal for roofing applications—be it metal roofs, gutters, roof tile installations, or flashing and sheet metal work.

Real-World Applications
Consider the demanding projects in Miami-Dade County, where environmental conditions can be challenging. Bostik 915 maximizes the wetting potential of the sealant to substrates, ensuring a robust bond before curing. It allows full cure within 7 days, making it ready for mechanical stress-testing procedures. For best results, always perform adhesion testing to confirm optimal performance.
