Whether facing harsh sun or heavy rain, this tape ensures your deck's structural elements remain in top condition, offering a worry-free solution that saves time and money on repairs and replacements over decades of use.

EASY INSTALLATION: LLPT deck flashing tape comes with a quick-release liner, making it incredibly flexible and easy to install, even on uneven surfaces. This feature speeds up the installation process significantly. Simply clean and dry the surface for optimal adhesion, then apply the tape. Its user-friendly design ensures that both professionals and DIY enthusiasts can achieve a perfect seal quickly and efficiently, enhancing productivity and reducing installation time.

SUPERIOR ADHESION STRENGTH: Engineered for maximum performance, LLPT deck tape offer heavy duty shear stress resistance and 50g/cm adhesive tensile strength.

FULL WEATHER WATERPROOF: Designed to withstand extreme temperatures from -25°C to 80°C, LLPT joist hanger tape remains stable under high humidity and UV exposure without becoming a gooey mess. It offers airtight sealing, effectively protecting deck joists from moisture and vapor. This high-performance tape meets and exceeds industry standards, ensuring your deck remains protected in all weather conditions, thereby preventing costly moisture damage and prolonging the life of your deck.

ADVANCED CONSTRUCTION: LLPT deck joist tape features a thick butyl adhesive layer, a smooth UV-resistant rubber layer, and an oil paper backing for easy peeling and application. This high-viscosity, waterproof tape reliably blocks water, oil, grease, moisture, and corrosive chemicals, providing superior defense against moisture infiltration. It extends the lifespan of your deck by preventing damage, ensuring peace of mind and maintaining your outdoor space's integrity.

Attention: To ensure the adhesion of the tape, make sure the surface of the wood is dry before use.
