About This

Instant Permanent Bonding: This 2" x 82' double-sided butyl tape features high-tack adhesive that bonds instantly to crawl space liners and masonry surfaces. No primer needed—once pressed, it stays stuck.
No-Tear Thickened Backing: We’ve reinforced the release paper to ensure it comes off in one piece. No more struggling with thin liners that rip and cause the tape to stick to itself, saving you time and material.
Engineered for Durability: With a 0.7mm (28 Mil) thickness, it provides the perfect balance of flexibility and strength. Resists UV, moisture, and corrosion, maintaining its sealing integrity under harsh environmental conditions.
Crawl Space & Basement Ready: The ultimate solution for securing moisture barriers to rough concrete walls. Effectively seals out water vapor and prevents dampness, contributing to a healthier home environment.
Easy Installation & Clean Cut: Simple to measure and install. While the adhesive is incredibly strong, it can be easily cut with scissors or a utility knife (do not tear by hand) for a professional, clean finish in any corner.
