In the Lab. In the Field. Innovation.

Cathedral Stone^® Products is the leading North American manufacturer-distributor of environmentally safe masonry restoration and preservation products. Since 1982, we have supported specifiers and contractors by providing laboratory-tested, environmentally safe products that are proven to stand the test of time – and the elements. Our full product offering includes natural mortars and grouts, as well as sustainable paints, paint strippers, water repellent, biological solution, and cleaners.

We are most widely known as the only company in North America that customizes mortars by testing the substrate, identifying their physical properties, and developing a compatible mortar. Our one-of-a-kind process, ongoing research, eco-friendly product line and constant innovation are fueled by our passion to continually find the best – and safest – method for restoring and preserving masonry.
