Glaze Supply black duct cloth tape, 50mm x 45m. A strong, high tack duct tape that is hand tearable and water resistant, and adheres to most surfaces. It is ideal for non-sensitive surfaces and applications, and it is hard wearing and long lasting, suitable for both indoor and outdoor use. As with any strong adhesive tape, test on a small area first if the surface is delicate or painted, because the tape is not intended for sensitive surfaces. Apply to clean, dry surfaces for the best grip. Cut the tape to length by hand, so no scissors are needed.
