Cathedral Stone Products, Inc.

Cathedral Stone Products are leaders in scientific masonry restoration.

After over 30 years in the laboratory, Cathedral Stone has got masonry restoration down to a science.

As the world’s premier manufacturer of masonry restoration mortar systems, and more recently a manufacturer of masonry restoration cleaning, stripping, coating and repellent systems, we put every one of our products to the test. Day after day. Year after year.

The result? A complete line of integrated systems that have been tried, tested, and scientifically proven to be completely compatible with the unique physical properties of all masonry substrates – and each other.

That’s why our systems work. That’s why our restorations last. The first time. Every time.

No wonder Cathedral Stone has become the partner of choice for architects, preservationists and historic building owners charged with restoring and preserving some of the most treasured architectural structures.
