Stucco (pronounced stuhk-oh)

(2) Any of various fine plasters for decorative work, moldings.

(3) Any of various finishes made with cement, plaster, or mortar, as albarium.

1590–1600: From the Italian stucco (fine plaster used as wall coating; coating made of pulverised gypsum, plaster), from the Lombardic (or Langobardic, an extinct West Germanic language was spoken by the Lombards (Langobardi), the Germanic people who settled in Italy in the sixth century. It was already in rapid decline by the seventh century because the invaders adopted the Latin vernacular spoken by the local Roman population) stucchi and related to the Old High German stucki & stukki (crust; piece; fragment) from the Proto-Germanic stukkjam & stukkiją (stump, piece), ultimately from the primitive Indo-European (s)teu- & (s)tewg- (to push, stick, knock, beat, shock, butt, impact) which evolved also into stock.  It was akin to the German Stück (piece), the Old Saxon stukki (piece, fragment) and the Old English stycce.  The Germanic form survives in Modern German as Stück.  Stucco and stuccoer are nouns, the noun plural being stuccoes or stuccos.  The verb (used with object) is stuccoed or stuccoing, a form attested from 1726.

In English, the meaning of stucco diverged from the Italian and Germanic sense from which it was borrowed.  Whereas in Italian when speaking of stucco, one might be referring either to the raw material or the finished product, in English, it means exclusively the latter.

The female figure is thought to represent a maenad, one of the female followers of Dionysos.  She’s depicted floating, her garment opened to the waist, her left leg revealed.  She holds a long, thin wand-like stick over her left arm, a garland with ribbons in her right hand.  Dionysus was the love child of Zeus and Semele and a rarity among the gods, his mother being a mortal.  While the parentage is certain, there are two different versions regarding the birth, which, in the way of Greek mythology involve infidelity, jealousy, infanticide (by Zeus’ bitter wife) and reincarnation and it’s the idea of re-birth which saw him adopted as a god by several religions.  Still his troubles didn’t end even after being re-born.  Zeus, an early example of the absent father, entrusted the upbringing of Dionysus to the rain-nymphs who proved so diligent they were rewarded by being turned into a star-cluster but this failed to impress Zeus’s wife, Hera, who remained angry the evidence of her husband’s unfaithfulness was still alive and in vengeance, inflicted madness upon the child.  In this state, for years and years he roamed the earth until rescued and cured by the goddess Cybele who instructed him in her rituals and he began to travel, teaching those he met how to make wine.  In symbology Dionysus is thus the god of wine and the grape harvest and, because of his difficult youth, also of ritual madness & religious ecstasy.  He’s depicted usually with a dual nature, the Greek’s cautionary tale about the good and evil of wine for Dionysus was known to bring happiness and joy to those around him but if angered, there could also be rage and brutality.

In architecture, most building materials and methods of construction were easily adapted to structures designed with straight lines and predictable angles but stucco was especially suited to the shapes and curves of art deco.  Stucco is made from a mix of Portland cement, sand, limestone, water and chemical additives to increase material’s strength and flexibility.  It creates a rigid and durable material and, being fire and pest-resistant, it’s always been popular in residential buildings.  It’s regarded as low-maintenance but shouldn’t be treated as maintenance-fee, cracks can appear, even in high quality installations and, despite appearances, can’t be dismissed a merely cosmetic and should immediately be re-sealed.  Stucco is porous, so may not be suitable to use in a tropical climate, the proneness to moisture absorption meaning mold can appear, either on the surface or underneath and once there, can spread to framing.  The vapor barrier, usually of tar paper, which should be applied prior to installation, does act as a protective layer but in some conditions isn’t all that ameliorative.

Lindsay Lohan’s former residence (2011-2012), 419 Venice Way, Venice, California 90291.  417 & 419 Venice Way are a pair of mirror-image stucco buildings, built in 2007.  Lindsay Lohan lived in the one on the right (419) while the left (417) was occupied by former special friend Samantha Ronson.

Where conditions are suitable, stucco is a good choice for either flat surfaces or creating curves.  Applied with a smooth or textured finish, it can be tinted across a wide spectrum or can be painted although, because of the porousness, many architects recommend against painting because it better to allow the building to “inhale and exhale”.  Stucco is durable, properly maintained stucco buildings over a hundred years old are common, many from the nineteenth century, the survival rate influenced as much by the prevailing climate as the quality of the installation.  The dampness which can cause mold through moisture transfer can also induce cracking in places prone to sub-zero temperatures, severe damage possible during freeze and thaw cycles.  Cracks can happen too in places subject to wide variations in temperature because, being rigid, as a structure expands and contracts, the forces of push and pull will stress the material.  For this reason, it’s ideal also to build in places of known geological stability, stucco more prone to fracture during movement than some other materials.  Cracks in stucco are not uncommon yet should be infrequent, repaired most often with a flexible exterior caulk and most are now elastomeric and thus both strong and very flexible.  Chips can be fixed with either a traditional stucco patch or, if large, set back in place using the acrylic caulk as a glue.
