Black Waterproof Decking and Joist Tape 96mm x 15.2m

This black bitumen-style flashing tape provides essential waterproof protection for timber structures. It is crafted from a durable, UV-resistant material designed to shield wood from moisture damage and rot. The tape features a self-healing acrylic adhesive that maintains a continuous seal even after fixings are driven through it. This makes it an ideal choice for homeowners and contractors who need to extend the lifespan of their timber investments. It is solvent-free and odourless.

You should apply this tape to deck joists, stair stringers, posts, and ledger boards to prevent water ingress. It is suitable for domestic garden decking projects as well as commercial walkways and ramps across the UK. Because it withstands heavy rain, it is particularly effective at protecting structural timber during a wet British autumn. Whether you are building a small patio in a residential garden or maintaining a large-scale public boardwalk, this tape helps maintain structural integrity. It works well on all exposed timber surfaces.

Preparation is straightforward. Ensure all timber surfaces are clean, dry, and free from debris before you begin the application. The tape features an initially repositionable acrylic adhesive, which allows for precise placement during installation. Once you have positioned the strip, apply firm pressure to ensure a permanent bond. You can drive nails or screws directly through the material. Because the adhesive is self-healing, it will seal around these fixings to prevent water from seeping into the wood grain.

This professional-grade tape comes in a single size option of 96mm in width and 15.2m in length. The black material is UV-resistant and offers all-weather performance that surpasses standard butyl tapes. It arrives in a convenient self-wound design to save time on site. The product is solvent-free and odourless, ensuring a safer working environment for installers. Each roll provides ample coverage for standard joist widths found in most UK decking constructions.
