A new adhesive built for smooth, efficient EPDM and TPO installations

By H.B. Fuller. 

H.B. Fuller's new Millennium Waterborne EPDM/TPO Bonding Adhesive delivers versatility and jobsite efficiency. 

Roofing crews looking to simplify installations without sacrificing performance have a new option to consider. Introducing Millennium Waterborne EPDM/TPO Bonding Adhesive: H.B. Fuller's newest product designed to deliver fast application, flexibility and long-term reliability to modern membrane roofing systems. Developed for smooth or fleece-back EPDM and TPO membranes, this water-based adhesive supports multiple application methods, making it a practical solution for both field membrane attachment and detailed flashing work. 

Contractors can apply the adhesive as a one-side wet lay-in on horizontal roof surfaces or as a two-side contact adhesive for vertical applications and flashings. This flexibility allows crews to rely on a single adhesive across different phases of a project, streamlining material selection and reducing complexity on the jobsite. 

Performance is central to the product’s design. The high-strength formulation is engineered to maintain the integrity of the installed membrane over time while delivering consistent adhesion across a wide range of approved substrates. These include wood, brick or block masonry, insulation and cover boards, giving contractors confidence when working with varied roof assemblies. 

Efficiency is another key advantage. The adhesive supports fast application using standard rollers or brushes, helping crews work efficiently with familiar tools and without specialized equipment. Its water-based formulation allows for easy cleanup and is VOC-free, supporting cleaner jobsites and simpler compliance with environmental requirements. 

Coverage rates of approximately 115–125 square feet per gallon help contractors accurately plan material usage whether applying adhesive to the substrate only or splitting coverage between the substrate and membrane for two-side applications  

Backed by H.B. Fuller’s long-standing expertise in roofing adhesives, Millennium Waterborne EPDM/TPO Bonding Adhesive offers contractors a reliable balance of performance, speed and versatility for modern EPDM and TPO roofing systems.
