Metal curtain wall and extrusions in prominent office buildings may need to be repainted either because the original factory applied finishes have dulled or because the owner wants to give the building a fresh look. Many monumental buildings are constructed with factory painted aluminum or steel cladding (curtain wall) and window extrusions. These buildings need to be repainted with field applied coatings that match the appearance and durability of the factory finishes. This paper will discuss the details of painting the exterior of tall buildings. Surface preparation, primers and available topcoats are discussed. Application challenges and case histories are presented.
