Gerband 587 external sealing tape adheres well to wood, smooth bricks, and solid concrete surfaces. It can also be bonded to porous or sandy substrates if primed, making it suitable for repairs or tears in membranes. Additionally, it seals all known pitched roof underlay and façade membranes. The tape features 60mm width, filament protection against over-expansion, and is very pliant, even in frosty conditions. It remains temperature-stable until 120°C and is UV resistant.
