Everbuild Black Jack Flashing Trade Tape 450mm x 10mtr

The Everbuild Black Jack Flashing Trade Tape in the 450mm x 10mtr format is a heavy-duty solution for contractors and DIY enthusiasts who require a dependable, wide-format waterproofing membrane. While standard tapes often fall short when dealing with broad surface areas, this 450mm variant is specifically engineered to bridge larger gaps, making it the ideal choice for valley gutters, chimney stacks, and roof-to-wall junctions where a narrower tape would necessitate multiple overlapping layers.

One of the primary advantages of Black Jack Flashing Tape is its versatility across various materials. It exhibits superior adhesion to brickwork, concrete, plaster, wood, glass, metals, and most plastics. This makes it a multi-purpose tool for the modern tradesperson, suitable for both new construction and emergency repair work. Whether you are sealing a leaking conservatory roof, patching a hole in a galvanized gutter, or providing secondary protection around window frames, this tape creates a long-lasting, flexible seal that moves with the building's natural thermal expansion.

The application process is remarkably straightforward, emphasizing safety and speed on-site. Unlike traditional lead or torch-on felt, this tape requires no naked flames or hot bitumen, significantly reducing the risk of fire and making it safer for use in domestic environments. For the best results, the surface should be dry, clean, and free of dust. In colder temperatures or on porous surfaces, using a flashing primer can further enhance the initial grab. Once applied, the tape should be smoothed down with a seam roller or a cloth to ensure 100% contact and to remove any air bubbles.

Beyond simple leak repairs, this trade-grade tape is an excellent preventative measure. By applying it to vulnerable joints before issues arise, you can extend the lifespan of roofing structures and prevent costly water damage to the building's interior. Its UV-resistant aluminium face ensures that it will not become brittle or crack under the sun’s rays, maintaining a watertight seal for years to come.
