Tuesday, October 8, 2024 | 12-1 p.m. Eastern Time

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.
