FANTASTIC-FILL is a polyurethane isolation primer with excellent body and remarkable surface smoothness, which in parallel optimises sanding characteristics and shortens the sanding process. Its application-friendly thixotropy also facilitates application on edges and vertical components, without negatively impacting levelling on horizontal surfaces. Even after brief drying, a surface treated with FANTASTIC-FILL can easily be lacquered from the rear and stored in a trolley. FANTASTIC-FILL has deliberately been developed for process-oriented, powdery manual and machine sanding.
