Product description

The GacoFlex A4700 roof coating system is a fluid-applied acrylic coating designed for the maintenance and renewal of existing roof surfaces. The system is applied as a primer plus topcoat configuration, providing strong adhesion and long-term weather resistance.

Primer: GacoPrime – Low VOC Primer, applied to promote adhesion to the substrate.

Topcoat: A4700 Acrylic Roof Coating, applied directly over the primer as the protective and functional layer.

GacoFlex A4700 can be installed over a wide range of roof substrates, including weathered single-ply membranes, metal, sprayed-in-place polyurethane foam, and asphalt membranes. It is designed to restore and extend the service life of existing roofs without requiring a separate basecoat layer.

Interpretation

Based on the results and study assumptions, methods, and data, the cradle-to-gate impacts (A1–A3) for the product represent approximately 40% of the total Global Warming Potential (GWP). The remaining impacts occur in later life-cycle stages.

LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
