Union Avenue Road Closure - Tuesday, September 16, 2014
Union Avenue will be closed to all activities (walking, biking, jogging, and vehicle tours) between the Memorial Arch and Pemberton Avenue beginning at 6:30 a.m., and remained closed until hazardous tree removal work in the area is completed.
Bronze and Metal Preservation
After using a pressure washer to loosen the dirt and grime on the metal, xylene is applied with a sponge to reverse the chemical process of oxidation. Restoration workers must use protective gloves and masks, and once the xylene evaporates, a tac rag is used to clean the surface and remove any left-over particles.
A final treatment of a cold wax forms a hard protective barrier to isolate the metal from the effects of weather, sunlight and airborne contaminants.
