U9 Series

UF90 GacoMastic

Efficient detail and seam application

UF90 GacoMastic is a fiber-reinforced mastic product for use on details and seams. It eliminates the need for three-coarse applications with embedded fabric, thus significantly reducing installation time. This single-component mastic also has a higher viscosity and sag to conform around details and in vertical applications.

Roof Maintenance
