UI-7119 Primer
UI-7119 Primer is a high penetration primer/sealer used to enhance the long-term adhesion of polyurethane membranes to wood, plywood, concrete, and treated metal surfaces. This two-component, low viscosity primer/sealer is insensitive to humid application conditions and will cure well in the desert and tropical environments. Using UI-7119 significantly reduces the incidence of pinholing and surface imperfections in polyurethane waterproofing installations compared to similar applications on untreated surfaces.
