The introduction of the many revival styles of architecture around the turn of the twentieth century, combined with the improvement and increased availability of portland cement resulted in a "craze" for stucco as a building material in the United States. All of these are regional variations on traditional mixtures of mud, clay, lime, chalk, cement, gravel or straw. Other historic treatments and coatings related to stucco in that they consist at least in part of a similarly plastic or malleable material include: parging and pargeting, wattle and daub, "cob" or chalk mud, pise de terre, rammed earth, briquete entre poteaux or bousillage, half-timbering, and adobe. "Render" and "rendering" are also terms used to describe stucco, especially in Great Britain. By the nineteenth century "stucco," although originally denoting fine interior ornamental plasterwork, had gained wide acceptance in the United States to describe exterior plastering. Historically, the term "plaster" has often been interchangeable with "stucco" the term is still favored by many, particularly when referring to the traditional lime-based coating. Up until the late 1800's, stucco, like mortar, was primarily lime-based, but the popularization of portland cement changed the composition of stucco, as well as mortar, to a harder material. Still widely used throughout the world, it is one of the most common of traditional building materials. Stucco has been used since ancient times. Although several stucco mixes are representative of different periods are provided here for reference Each project is unique, with its own set of problems that require individual solutions Successful stucco repair requires the skill and experience of a professional plasterer. Stucco is a material of deceptive simplicity: in most cases its repair should not be undertaken by a property owner unfamiliar with the art of plastering. Like most historic building materials, stucco is at the mercy of the elements, and even though it is a protective coating, it is particularly susceptible to water damage. Age and lack of maintenance hasten the deterioration of many historic stucco buildings. Historic stucco is also sometimes incorrectly viewed as a sacrificial coating, and consequently removed to reveal stone, brick or logs that historically were never intended to be exposed. It is so common, in fact, that it frequently goes unnoticed, and is often disguised or used to imitate another material. Stucco is found in many forms on historic structures throughout the United States. If it feels loose, replace it with new plaster or pin it down with plastic washers.The term "stucco" is used to describe a type of exterior plaster applied as a two-or-three part coating directly onto masonry, or applied over wood or metal lath to a log or wood frame structure. The plaster has to adhere to the wood lath in the wall in order to be sturdy.It could get in the way of the new material you install. Remember to remove all the loose plaster inside the hole as well.You will notice it as you look through the hole. Plaster walls generally include a wood surface called a lath.Make sure the existing plaster is flat and smooth so the new plaster adheres to it properly. The easiest way to do it is by lightly tapping the loose plaster with a hammer or paint scraper, then sanding the edges of the remaining plaster with 120-grit sandpaper. Remove enough of it to create a flat, stable base for the new coat of plaster needed to cover the hole. Clear out the bits of plaster hanging around the hole’s opening. Remove the loose or damaged plaster around the hole.
