I have a Midwest restoration project dealing with red sandstone (from the U.P.
Michigan). Test patches, etc. --- I know the routine. But would like a few
comments about appropriate patching materials - particularly from you
Connecticut/NY area professionals ( I remember the brownstone well).
Has anyone tried the Keim patching mortars? They make the stucco with mineRal
coating (not film-forming) which is excellent, but I see they are now in the
patching mortar business.
Thanks, Anne
