This tape provides and completely waterproof and weatherproof seal when wrapped tightly round a joint.

PLEASE NOTE: This tape has a very thin protective plastic strip  on it that prevents the tape sticking to itself which needs to be peeled off to get it to stick to itself. If this protective strip is not peeled off then the tape will not work as it is intended to. Please try peeling this protective layer off before contacting us stating the tape does not stick to itself!!!
