Gaco™, part of the Holcim Building Envelope portfolio of brands, has introduced the GacoFlex A48 acrylic roof coating. GacoFlex A48 is the first and only single-component, high-build acrylic roof coating that can be applied up to 80 wet mils (5 gal/SQ) in a single pass application1. A fast-cure acrylic elastomeric roof coating, the product offers a long roof life, upgraded visual appeal, strong adhesion, high tensile strength and excellent reflectivity. 

GacoFlex A48 can be applied as a roof maintenance coating over many existing roof substrates, including single-ply, metal, sprayed-in-place polyurethane foam, and asphalt membranes. It provides early rain resistance in as little as 30 minutes, with complete cure-through in about eight hours2. In addition to its easy application, the product can be sprayed from a standard acrylic spray system and does not require more expensive plural component equipment.

1As of March 30, 2023, GacoFlex A48 is the only product in the single-component acrylic roof coating segment with application rates up to 80 wet mils in one pass.

2Exact cure-through time will vary based on ambient temperature, humidity and mil thickness.
