The newly rebuilt Rotunda dome at the University of Virginia will remain copper-colored for Final Exercises.

Crews from E. Caligari & Son Inc. of Norfolk planned to paint the dome white this week, using a fluoropolymer mixture from PPG Paints, but this week’s rain is preventing it. The painting plan calls for two coats – a primer coat, then a finish coat.

“We need dry weather for about four to six hours after the primer is applied,” said Jody Lahendro, historic preservation projects manager for Facilities Management. “The weather forecasts call for 40 percent chance of rain every day this week.”

University officials, on the advice of construction managers Christman-Gilbane, agreed Monday not to attempt to paint the dome before the May 19 Final Exercises.

“This is too complicated and intricate to try and rush through it,” Lahendro said.

That means that this year’s graduation photos will be the first to have a copper-clad Rotunda dome in the background since before the last round of major Rotunda renovations, completed in 1976.

Crews have spent the past year replacing the roof on the University’s centerpiece Rotunda, the first phase of an extensive $50 million restoration and repair project. The roof work, which involved replacing the steel dome with a copper one, is completed – several months ahead of schedule – and the scaffolding that has bracketed the Rotunda for the past year has been taken down, leaving the final touch of painting the dome.

The copper roof must be specially prepared for the paint, including being gone over with a fine-grit sandpaper.

“They finished all the sanding on Sunday,” Lahendro said. “So when we do paint it, that is already done. We will need to scour the metal to clean it again, but that should be all.”

Lahendro said the painting crews plan to be back on the roof assessing the situation the day following graduation.
