Overheard a foreman say lime mortar is only for historical houses
Told this old timer on a site last month that I use NHL 3.5 on a garden wall and he laughed saying modern Portland is all you need, but isn't lime better for the bricks breathing in the long run, who's got the right take here?

Totally agree with you, climate is a HUGE part of it. I put lime mortar on a south facing wall here in the US northeast and it soaked up the rain way better than the old Portland I patched last year. That old timer might be fine in a dry area, but where I am brick NEEDS to breathe or you get spalling within five years.
