It withstands UV rays and harsh weather conditions, providing long-lasting protection for construction structures. Its wide-ranging applications cover deck installation, roof patching, pipe sealing, and more. The tape adheres well to various materials, including wood, metal, plastic, and rubber. Installation is straightforward and convenient. The self-adhesive backing with an easy-peel protective film allows for quick application. After installation, the adhesive strength gradually increases, reaching its maximum within 24 hours. In cold environments, warming the tape with a hairdryer enhances adhesion.
