Geocel RP-400 Wet-Dry Surface Roof Cement | Asphalt Based | Construction Grade

Roof cement engineered for professional roofing, construction, manufacturing, and industrial applications on wet or dry surfaces.

The Geocel RP-400 Construction Plastic Wet-Dry Surface Roof Cement is a single-component, asbestos-free, asphalt-based cement that seals quickly and reliably on virtually any surface — even underwater. Formulated to bond fast without pulling apart or losing adhesion over time. Remains soft and pliable after curing and resists temperature change for long-term performance in demanding outdoor conditions.

Compatible with asphalt, steel, brick, wood, aluminum, and most common building substrates. Ideal for heavy duty truck and trailer applications as well as roofing installations.
