Another major renovation program has just been completed. The first phase of work was devoted to the façade, sprucing up moldings, stone blocks, and joints. The chief architect of the Register of Historic Places wanted the 19th-century natural-cement repair work on sculpted stone to be repaired using the same materials.
 

On the request of Tollis, a subsidiary of the Lefèvre Group specializing in restoration, Vicat Cement team, drafted a specification that would be an identical match to the stonework and sculpture while conserving the history of 19th-century repairs. Obviously only PromptUP natural quick-setting cement was up to the task!

Prior to the start of restoration, the Vicat specification and application advisor performed color testing, mixing PromptUP with local sands of different shades until he found the color required by the architect. He also trained the restorers. The site crews then renovated the statues at the entrance and at the top of the listed Gothic building. Finishing of the statues and molding required the finest skills. A second phase of restoration will get under way before the second half of 2016.

Subsequent to the success of the first phase, the research laboratory of the Register of Historic Places (LRMH) has asked us to help with the same kind of restoration work on Troyes and Angers cathedrals.
