GAF is leading the way in delivering solutions that help contractors save time and labor. Our latest innovation is the industry-first Everguard® TPO Primerless Cover Tape, a six-inch tape for stripping in edge metal that, just as its name implies, doesn't require the use of primer. This factory-built primerless cover tape consists of a non-reinforced TPO membrane that's backed with a butyl tape adhesive. It ensures that contractors achieve the highest quality installation with a uniform appearance and reduces the risk of leaks and callbacks.
