The surface of the roof was prepared according to Freedom® Chemical Corporations specifications. Freedomtuff® 6160 was applied at 8 mils and a 30-mesh sand was broadcast into the primer, then the Freedomtuff® 2190 polyurea was sprayed at 80 mils and 40 mils of Freedomtuff® 4300 was applied over the surface.
The previous specified system required the use of hot mop (tar) with fabric between each layer having a strong sulfur smell for several days during application. The FreedomTuff GuardianGreen system has no odor. The previous specified system had limitations to the that could be used. This required the purchase of the vegetation from the same supplier. The FreedomTuff® GuardianGreen™ system has no limitations for overburden and vegetation, no root barrier was required, no sulfur smell (tar) and doesn’t require termination points.
