Old timer in Omaha showed me a trick with lime mortar
I was working on a 1920s church foundation outside Omaha last spring, and an old bricklayer named Hank walked over and told me to stop using modern mortar for the repointing. He said I had to match the lime content or the brick would spall in 5 years. Has anyone else dealt with older buildings where the standard mix just doesn't work?

You ever notice how the old guys always have a weird sixth sense about materials? We had a similar thing with a 1900s schoolhouse roof in Iowa. The roofer kept trying to put on asphalt shingles and the owner said no, had to be cedar shakes because of the way the old boards breathe. It was a whole thing with moisture getting trapped. Ended up custom ordering shakes from a mill in Wisconsin that still does them the old way. Took two extra weeks but I bet that roof outlasts anything modern.

Found out the hard way with a 1910 farmhouse that modern mortar cracks old brick faster than you think.
