I called that new lime putty stuff a fad until my rep pointed at a wall we did in '08.
The mortar joints were still perfect, no efflorescence at all. I've been mixing my own for twenty years, but that old job convinced me to give it a real shot on a chimney rebuild last fall. Anyone else switch over and notice a difference in freeze-thaw areas?

That old lime putty job is what finally sold me on it too.

Watched a neighbor's repointed foundation with modern mortar crack after two winters. My test patch with the putty right next to it just looks damp sometimes, but it's holding tight. Makes me wonder if the slower cure lets it move just enough without breaking.
