Founded by Dennis Rude in 1982, Cathedral Stone Products is known for its line of Jahn restoration mortars that can be custom blended for a specific project, as well as for potassium-silicate mineral coatings that mechanically bond to masonry and create a breathable surface that resists airborne contaminants, cracking and peeling. It provided Jahn mortars, matched to existing sandstone, to help restore the historic Cut River Bridge in Michigan’s Upper Peninsula. The $800,000 project was subject to Michigan State Historic Preservation Office approval. The bridge offers spectacular views of Lake Michigan and is now listed on the National Register of Historic Places.

Citing a dedication to quality and the highest standards, Cathedral Stone Products conducts American Institute of Architects-accredited seminars and hands-on workshops for architects, engineers and construction specifiers throughout the year, along with masonry contractor certification programs. The company is a sponsoring partner for the Association of Preservationists Technology conference (APT 2016) in San Antonio, October 30–November 2.
