About This Project

Project involved a complete restoration and in large part, new construction for this aged subway station.  KEIM was specified for the mineral stucco and sol-silicate mineral coating which was applied for all interior spaces as well as the exterior subway platform that was covered by a roof portico.
Challenges The condition of the concrete, the thick layers of old paint, graffiti tagging and the condition of surfaces interior and exterior involved a comprehensive specification involving concrete repair and concrete re-building. In general, the Specification depended upon addressing the best surface preparation for existing areas as well as new concrete areas.
Solutions The KEIM products used included: Concrete Cleaner, UniversalPutz with Fiber Mesh, Lime Remover, Silan 100, Concretal-W Grob (two coats), Concretal-W Top Coat, and finally, KEIM PSS 20. Due to the potential for graffiti tagging, KEIM PSS 20 was installed.
