Preservationists are moving to block President Donald Trump's plan to test a controversial paint on the Eisenhower Executive Office Building, warning the project could cause irreparable damage to the historic landmark, according to a new report.In an emergency injunction request set to be filed Thursday, the law firm Cultural Heritage Partners argues that the administration's plan to paint four small test panels on the building's Gilded Age façade is being carried out without proper expert oversight, reported CNN."The testing concerns us because no one outside the White House knows who is conducting the testing or what protocols they're following, and qualified preservation experts have had no chance to weigh in," said Greg Werkheiser, the firm's founding partner.Trump has long criticized the EEOB's gray granite exterior, calling it "ugly" and a "really bad color," and has pushed to coat the building — either fully or partially — in white to better match the White House.His preferred solution is a mineral silicate paint he has privately refers to as "magic paint," which the administration claims will strengthen the stone and prevent water intrusion – but those claims are disputed by experts.In March, the plaintiffs presented findings from 25 unnamed specialists in historic restoration and silicate paint, who concluded the material doesn't chemically bond with granite, would cause permanent damage during the priming process, and would not actually strengthen or protect the stone as claimed. Preservationists also warn the paint could trap moisture inside the granite, accelerating deterioration rather than preventing it.Adding to the controversy, the administration has shifted oversight of the project away from the General Services Administration — which normally holds statutory authority over the 1888 building — to the White House's own Office of the Administration. Critics say this move could allow the project to sidestep the review process Congress mandated to protect historic federal properties.The administration maintains the panel testing doesn't commit it to full-scale painting and says it's still working through required environmental and historical reviews with two other federal bodies, the Commission of Fine Arts and the National Capital Planning Commission — both of which have been staffed with Trump allies and would need to approve any final plan.Beyond the paint test, the administration also plans a broader facade assessment, including extracting up to ten two-inch stone samples from deteriorating sections of the building for lab analysis. It remains unclear how quickly U.S. District Judge Dabney Friedrich, a Trump appointee overseeing the case, will rule on the injunction request once filed.
