The Würenlos motorway bridge between Zürich and Baden is the largest in Europe, popularly known as the «feeding trough». More than 120,000 vehicles whoosh underneath it, day in and day out. Soot and dirt particles, light and UV rays, wind and weather: because the façade is exposed to the most extreme conditions, it is ideal for “road testing” Qualiprotec.
In summer 2010 two square meters of the aluminium façade were cleaned (dirt and chalking removed) with Qualiprotec Cleaner N, then cleaned thoroughly with Qualiprotec Abrasive B and white pad to achieve a clean, slightly roughened surface. Finally Qualiprotec Re-Vitaliser Q35, a clear satin-gloss coating, was applied. Result: the original color looks just like new. Inspection after three years proves: there is zero change in color. The motorway “road test” underlines the excellent results of the Florida test, the toughest color test in the world.
