What surface finishes are best for coastal façade projects?
Coastal environments challenge façades with salt spray, high humidity, and intense UV exposure. To protect aluminum panels, PVDF (polyvinylidene fluoride) coatings provide exceptional corrosion resistance, color retention, and UV stability for over 20 years. Anodizing forms a hard oxide layer that resists salt-induced corrosion while preserving a natural metallic appearance; architectural anodized finishes meet rigorous marine standards when properly sealed. Ceramic clear coats add another barrier against abrasion and chlorides without obscuring anodized color. When specifying finishes, consider coil-coated PVDF systems formulated for Class 2 or 3 climates and ensure regular maintenance to remove salt deposits. By selecting these finishes, architects and building owners can achieve durable, attractive façades that withstand the harsh conditions of seaside locations.
