Black Decking and Joist Flashing Tape 152mm x 15.2m

This durable bitumen-style tape provides a robust waterproof barrier for timber structures. It features a self-healing property that maintains a seal around nails and screws. The acrylic adhesive is solvent-free and odourless. This ensures the material remains stable when exposed to the elements. It is specifically engineered to withstand UV exposure and heavy rainfall throughout the British winter.

Use this tape to protect the hidden components of your garden decking. It is ideal for covering joists, stair stringers, posts, and ledger boards. By sealing these areas, you prevent water from sitting against the wood. This application is essential for both residential garden decks and commercial timber walkways. It helps extend the lifespan of the entire subframe.

The initially repositionable adhesive allows for precise placement during installation. Simply clean the timber surface before application to ensure a strong bond. Once pressed down, it creates a continuous waterproof seal. This makes it easy to align the tape perfectly along the length of your joists.
