Power Patch tape is a strong, rubberized tape that is also waterproof. It is used mainly to patch and repair items that need to remain water tight. For example, repairing a tear in a tarp would be an appropriate use of patch tape.
How do I use Power Patch tape?
As patch tape routinely faces the elements, it’s important to get the best seal possible. If you are able to, clean the area around the repair. Measure out the length required, cut, and press down firmly. There should be no air pockets underneath the tape.
