TPO Primer
Surface-Bonding Primer for New and Weathered TPO Roofs
TPO Primer is a fast-drying, liquid primer engineered to improve coating adhesion on TPO and other single-ply roofing systems. Whether you're applying over new TPO, weathered single-ply, or metal surfaces like stainless steel and aluminum, this primer ensures strong, lasting bond strength for NanoTech's Cool Roof Base Coat and other roof coatings.
Simple to apply and quick to dry, it enhances system longevity and reduces the risk of delamination in restoration projects—particularly where coating adhesion is critical to long-term performance.
