Mike,
Does Home Depot sell a Type S mason's lime? I have not found it there.
Neither in Lowes. In fact, the most sophisticated mason's yard in our
area of LI (cash only) quite often does not have hydrated lime in stock
at all. The mason's around here do not know what to do with it. The
supplier is curious why I keep asking for it. If I want to get anything
but agricultural lime at Agway I need to go into the city for it. Same
goes for non-staining Portland or a case of urethane caulk that is not
shelf weary, or lead coated copper. Which goes again to my focus
pertaining to geographic determinism. Seventy miles out from NYC the
common masonry practice these days is not nearly as sophisticated as it
was in Ken's 19th century books. A major portion of activity on the
earth is not documented.
As I see it the lime guys come from areas where the masonry stopped as a
main-stream convenient building technology in preference for wood
structures. Though they may have had 19th century banks & courthouses
built w/out lime for the most part when they are thinking historic they
are seeing all around them structures built with lime mortars.
