Cathedral Stone Products is the exclusive supplier of Jahn Restoration Mortars. Jahn Restoration Mortars are the best products available for repairing stone. Their products have the best bond, best breathability, and greatest ability to withstand salt and water in the winter. They don’t shrink. They contain no bonding agents which tend to eventually fail, causing the patch to fail and need to be redone. Jahn Restoration Mortars are also able to be carved once installed.
They do not sell their products without training classes on how to use them correctly. These are images of work I completed in class to show the versatility of their products.
