2-Sided Butyl Tape: Instant Bond for Plastic Sheeting
Double-sided butyl Tape provides a practical, instant-bond solution for securing plastic sheeting to porous surfaces like concrete. Its strong adhesive properties make it an excellent choice for contractors working on crawl space encapsulation, vapor barriers, and waterproofing applications.
Easy to Use
2-Sided Butyl Tape is designed for quick and hassle-free application. It features a quick-release liner that streamlines the installation process while minimizing mess, making it ideal for projects where efficiency matters. The double-sided adhesive ensures a strong bond without additional fasteners, simplifying the process of overlapping poly sheeting panels in crawl spaces and other critical areas.
Reliable Adhesive Bond
Constructed with high-quality butyl mastic adhesive, this tape bonds securely and permanently to both smooth and textured surfaces, ensuring long-lasting durability. Unlike traditional adhesives that may weaken in extreme conditions, Double-Sided Butyl Tape maintains flexibility in cold temperatures and retains its structural integrity in hotter conditions. This makes it a dependable sealing solution for vapor barriers and moisture control applications.
Reinforced for Strength
Durability is a key advantage of 2-Sided Butyl Tape. It features built-in cloth reinforcement, which helps prevent tearing and ensures a reliable hold over time. The double-coated PET film liner allows the tape to be hand-tearable, making it easy to adjust and apply on-site without requiring additional cutting tools. This added strength makes it an excellent option for sealing seams, securing plastic sheeting, and ensuring long-term adhesion in high-traffic or high-moisture areas.
Double-sided butyl tape provides a reliable, long-lasting solution for creating airtight and moisture-resistant seals, whether you’re overlapping vapor barriers, sealing plastic sheeting, or working on crawl space encapsulation.
Installation Tips: 2-Sided Butyl Tape is designed to perform reliably in all temperatures once applied. However, following these tips during installation will help ensure a strong, long-lasting bond from the start.
