Trusted a guy about lime mortar, now my wall is sweating

Old timer at the yard swore lime was fine for a garage re-point in 40s weather. Two weeks later the frost pushed half the joints out, costing me $300 in redo material. Anyone else been burned by traditional-ratio advice on fast jobs?

man that sucks, I feel you. Same thing happened to me last spring, trusted this old school guy about using a hot lime mix on a shed and figured it would set up fine before a cold snap. Nope, three days later the whole south wall looked like it had the measles, little craters everywhere. I had to chip out every joint and redo it with a modern mix that had some cement in it, cost me a full weekend plus another bag of mortar. The worst part is the old timer just shrugged and said "shoulda checked the forecast," like it was my fault for listening to him lol. Now I only use lime for summer work or inside, never for anything that might freeze before it cures, lesson learned the hard way.
