Historic stucco has been used for centuries as a functional and aesthetic exterior finish for masonry substrates. A trowel-applied system, stucco historically used varying proportions of cementitious binder, aggregates, and hair in layers, and would be finished by the craftworker in a smooth, textured, or even an “ashlar” pattern. Review the history and evolving composition of stucco in the United States. We’ll identify deterioration sources and appropriate maintenance practices including repair and replacement techniques. Lastly, get tips for specifying stucco restoration and learn how to find skilled, trained preservation tradespeople to do the work.
