Aloha!
I have a question on lime plaster. I am restoring a building in Hawaii
that originally had lime plaster as an exterior wash over coral blocks.
The original recipe for this plaster wash recorded in archival
materials from 1832 was: “The receipt (sic) for the cement is as
follows: take one measure of sand, two of wood ashes, and three of
lime. Mix them together with such a coloring as may be fancied and let
the materials be combined with as much oil as will allow of (sic) the
substance being put on with a painters brush.” On other buildings clay
was added to the lime mixture. What does the wood ash do in this
recipe? Is lime plaster being used today? Thanks!
