Plastering
Plasterwork is construction or ornamentation done with plaster, such as a layer of plaster on an interior or exterior wall structure, or plaster Molding (decorative), decorative moldings on ceilings or walls. This is also sometimes called pargeting. The process of creating plasterwork, called plastering or rendering, has been used in building construction for centuries. For the art history of three-dimensional plaster, see stucco. History The earliest plasters known to us were lime-based. Around 7500 BC, the people of 'Ain Ghazal in Jordan used lime mixed with unheated crushed limestone to make plaster which was used on a large scale for covering walls, floors, and hearths in their houses. Often, walls and floors were decorated with red, finger-painted patterns and designs. In ancient India and China, renders in clay and gypsum plasters were used to produce a smooth surface over rough stone or mud brick walls, while in early Egyptian tombs, walls were coated with lime and gyps ...

Gypsum Plaster
Plaster is a building material used for the protective or decorative coating of walls and ceilings and for Molding (decorative), moulding and casting decorative elements. In English, "plaster" usually means a material used for the interiors of buildings, while "render" commonly refers to external applications. The term stucco refers to plasterwork that is worked in some way to produce relief decoration, rather than flat surfaces. The most common types of plaster mainly contain either gypsum, lime plaster, lime, or cement plaster, cement,Franz Wirsching "Calcium Sulfate" in Ullmann's Encyclopedia of Industrial Chemistry, 2012 Wiley-VCH, Weinheim. but all work in a similar way. The plaster is manufactured as a dry powder and is mixed with water to form a stiff but workable paste immediately before it is applied to the surface. The reaction with water liberates heat through crystallization and the hydrated plaster then hardens. Plaster can be relatively easily worked with metal t ...

Stucco Plaster Tools
Stucco or render is a construction material made of aggregates, a binder, and water. Stucco is applied wet and hardens to a very dense solid. It is used as a decorative coating for walls and ceilings, exterior walls, and as a sculptural and artistic material in architecture. Stucco can be applied on construction materials such as metal, expanded metal lath, concrete, cinder block, or clay brick and adobe for decorative and structural purposes. In English, "stucco" sometimes refers to a coating for the outside of a building and "plaster" to a coating for interiors. As described below, however, the materials themselves often have little or no difference. Other European languages, notably Italian, do not have the same distinction: ''stucco'' means ''plaster'' in Italian and serves for both. Composition The basic composition of stucco is lime, water, and sand. The difference in nomenclature between stucco, plaster, and mortar is based more on use than composition. Until t ...

Molding (decorative)
Moulding (British English), or molding (American English), also coving (in United Kingdom, Australia), is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster. A "plain" moulding has right-angled upper and lower edges. A "sprung" moulding has upper and lower edges that bevel towards its rear, allowing mounting between two non-parallel planes (such as a wall and a ceiling), with an open space behind. Mouldings may be decorated with paterae as long, uninterrupted elements may be boring for eyes. Types Decorative mouldings have been made of wood, stone and cement. Recently mouldings have been made of extruded polyvinyl chl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pargeting
Pargeting (or sometimes called Wall pargetting) is a decorative or waterproof plastering applied to building walls. The term, if not the practice, is particularly associated with the English counties of Suffolk and Essex. In the neighbouring county of Norfolk, the term "pinking" is used. Patrick Leigh Fermor describes similar decorations on pre-World War II buildings in Linz, Austria. "Pargeted façades rose up, painted chocolate, green, purple, cream and blue. They were adorned with medallions in high relief and the stone and plaster scroll-work gave them a feeling of motion and flow." Pargeting derives from the word 'parget', a Middle English term that is probably derived from the Old French ''pargeter'' or ''parjeter'', to throw about, or ''porgeter'', to roughcast a wall.''Webster's Dictionary''. However, the term is more usually applied only to the decoration in relief of the plastering between the studwork on the outside of half-timber houses, or sometimes covering the ...

Lime (material)
Lime is an Inorganic compound, inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The International Mineralogical Association recognizes lime as a mineral with the chemical formula of CaO. The word ''lime'' originates with its earliest use as building mortar and has the sense of ''sticking or adhering''. These materials are still used in large quantities in the manufacture of steel and as building and engineering materials (including limestone products, cement, concrete, and mortar (masonry), mortar), as chemical feedstocks, for sugar refining, and other uses. Lime industries and the use of many of the resulting products date from prehistoric times in both the Old World and the New World. Lime is used extensively for was ...

Sgraffito
(; ) is an artistic or decorative technique of scratching through a coating on a hard surface to reveal parts of another underlying coating which is in a contrasting colour. It is produced on walls by applying layers of plaster tinted in contrasting colours to a moistened surface, and on pottery by applying two successive layers of contrasting slip (ceramics), slip or glaze to an unfired ceramic body. The Italian past participle is also used for this technique, especially in reference to pottery. Etymology The term is based on the verb 'to scratch', which probably entered Italian through Lombardic language, Lombardic and ultimately traces back to the Greek word 'to write'. The Italian prefix 's-' originates in the Latin prefix 'ex-', and is used in this case to intensify the basic meaning, so that 'to scratch' becomes 'to scratch off'. History Sgraffito on walls has been used in Europe since classical times. It was popularized in Italy in the 15th and 16th centuries a ...

Scagliola
Scagliola (from the Italian language, Italian ''scaglia'', meaning "chips") is a type of fine plaster used in architecture and sculpture. The same term identifies the technique for producing columns, sculptures, and other architectural elements that resemble inlays in marble. The scagliola technique came into fashion in 17th-century Tuscany as an effective substitute for costly marble inlays, the pietra dura works created for the House of Medici, Medici family in Florence. The use of scagliola declined in the 20th century. Scagliola is a composite substance made from plaster of Paris, glue and natural pigments, imitating marble and other hard stones. The material may be veined with colors and applied to a core, or desired pattern may be carved into a previously prepared scagliola matrix. The pattern's indentations are then filled with the colored, plaster-like scagliola composite, and then polished with flax oil for brightness, and wax for protection. The combination of materials ...
