I finally tried a lime mortar mix on a small repair job last week

I had an old brick wall on a house near Toledo where the joints were crumbling bad. My usual portland mix felt too hard for the soft old bricks, so I went with a lime putty mix for the first time. Mixed it on a hot day and the stuff stayed workable way longer than I expected, which threw off my timing a bit. The final result looked more like the original mortar, but I am not sure how it will hold up over a few winters. Has anyone here stuck with lime mortar for longer projects and seen how it handles freeze thaw cycles?

Did your buddy try that lime mix on an old chimney too?

Oh wow, that's a blast from the past. He tried it on a chimney that was probably fifty years old, said the lime mix made it look like new again. I still can't believe he did it with no respirator though - the dust cloud alone would have choked a horse.
