The Kansas statehouse in Topeka, Kan., is boasting a bright and shiny new exterior, thanks to a massive restoration project that began about 13 years ago.
The nearly $330 million project was divvied out into 29 separate bid packages, and two of those involved removing stains from the building’s multiple substrates, and were carried out by Treanor Architects, with offices in Kansas, Missouri and Texas.
Julia Mathias Manglitz, preservation architect at the firm, helped oversee the four-year, $34 million masonry restoration that began in 2008.
On the building’s exterior, they used PROSOCO’s Enviro Klean® SafRestorer® on metallic staining on the structure’s granite and limestone, and ReVive (formerly BioWash®) and ReKlaim Cleaner (formerly BioKlean) on biological stains on the limestone.
PROSOCO’s Conservare® OH100 was also used on the statehouse.
Why were so many PROSOCO products considered for this tough job?
The firm had previously worked with and specified PROSOCO formulas, and Mathias Manglitz said they’d “always had good product support on PROSOCO products.”
The firm conducted preconstruction testing with three to four different manufacturers’ products.
Of those contenders, “PROSOCO seemed to have the best suite of products to work with the different things we had to deal with, primarily biological staining, but also copper and rust staining,” she added. “We did have to specify other products because it was publicly bid, but the restoration contractor (Mark 1 Restoration) out of Chicago also had a comfort level with PROSOCO and a history of having used their products.”
Mark 1 Restoration completed its own round of testing and confirmed its decision to use PROSOCO’s products on the project.
The final, completed product wowed visitors during a ribbon-cutting ceremony earlier this month. The Kansas statehouse will take the spotlight again on Jan. 29, as part of activities planned to celebrate the anniversary of Kansas’ admission to the Union.
As for Mathias Manglitz?
“It’s a pretty special (project),” she says. “We’re really proud of it.”
