Yesterday I went to a Masonry Repair Workshop given by Cathedral Stone and sponsored by the Western Chapter of the Association for Preservation Technology. They covered the Jahn Restoration Mortars and we all got a chance to prepare a patch. Though I am already quite familiar with the product, it was fascinating to get to use it. I expected it to be wetter and stickier, and I was surprised at how hard it is to build up a patch that is overhanging.
