Hi Guys;

Just one overdue comment. There have been buildings built in Maine using sea water in the lime mortar and they did not hold up. Don't use salt water.

I can't say I have ever seen a mortar laid wall in Northern New England, just dry laid, sometimes pointed with mortar from the inside in a cellar.
