Gaco™ Launches GacoFlex A48 Acrylic Elastomeric Roof Coating

NASHVILLE, TN – April 14, 2023 – Gaco™, part of the Holcim Building Envelope portfolio of brands, has officially 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, GacoFlex A48 offers a long roof life, upgraded visual appeal, strong adhesion, high tensile strength and excellent reflectivity—while boasting environmentally friendly benefits and reduces landfill by avoiding costly tear-offs. With enhanced film build and reduced cure time, GacoFlex A48 helps roofing contractors complete jobs faster and with fewer materials.

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, GacoFlex A48 can be sprayed from a standard acrylic spray system and does not require more expensive plural component equipment.

“For over 60 years, Gaco has provided innovative, market-leading products that help contractors succeed and make their businesses more efficient,” said Carl De Leon, Senior Vice President of Technology, Holcim Building Envelope. 

“A48 leverages the latest developments in roof coating technology, resulting in a sustainable product that streamlines the application process.”

GacoFlex A48 upholds Holcim’s commitment to developing the highest quality products and sustainable, innovative solutions that stand the test of time and the elements while contributing to a healthier planet. The water-based solution is zinc-free and contains low VOCs (volatile organic compounds), making it an environmentally friendly option with no geographic restrictions. The coating will launch in white, with gray and tan options coming later this year.

Gaco is a recognized leader in innovative roofing systems and offers best-in-class waterproofing and insulation solutions for a variety of commercial, industrial and residential applications.
