GAF’s EverGuard Primerless TPO 6” Cover Tape uses a proprietary high-tack, high-adhesion butyl tape with “tackifying” resins that emulate primer for strong, reliable bonds.

The self-adhered solution streamlines labor-intensive strip-in, repairs, and maintenance while matching the performance of primed systems.

The challenge with TPO is its low surface energy, which makes it resistant to water but also difficult to bond to. While traditional methods have required a primer to overcome this, GAF's solution uses a proprietary, high-tack, high-adhesion butyl tape with specially formulated "tackifying" resins. These resins are designed to emulate the role of a primer, ensuring a strong, reliable bond without the labor-intensive priming process. 

GAF’s Primerless TPO Cover Tape achieves full adhesion in typical installations in approximately 24 hours—a timeline comparable to cover tapes that require primer—demonstrating that "skip the prime time" does not mean compromising on performance. The product’s patent-pending technology provides a self-adhered solution for labor-intensive strip-in and is also great for repairs and maintenance, proving that GAF’s industry-first product is just as effective as methods that require primer, without the added steps.
