A mural is any piece of artwork painted or applied directly on a wall, ceiling or another permanent surface. A distinguishing feature of the mural painting is that the architectural elements of the given space are harmoniously incorporated into the image.

Some wall paintings have been painted on large canvases, which are subsequently attached to the wall (e.g., together with marouflage). Whether these works can be correctly called “murals” is a subject of some controversy in the art world. However, the technique was in common usage since the late 19th century.

Historical mural methods
In the background of mural several approaches have been used:

A fresco painting, by the Italian word affresco which derives from the adjective fresco (“fresh”), refers to a way in which the paint is used on plaster on walls or ceilings. The pigment is then absorbed by the wet plaster; after numerous hours, then the plaster dries and responds with the air: it is this chemical reaction that fixes the pigment bits in the plaster. After this, the painting stays for a long time up to centuries in fresh and glorious colors.

Fresco-secco painting is done on dry plaster (secco is “dry” in Italian). The pigments thus want a binding medium, like an egg (tempera), paste or acrylic to attach the pigment to the wall.

Mezzo-fresco is painted on nearly-dry plaster and has been characterized by the sixteenth-century writer Ignazio Pozzo as “company enough to not take a thumbprint” so that the pigment just penetrates slightly to the plaster. From the end of the sixteenth century, this had displaced mainly the buon fresco method, also has been used by painters such as Gianbattista Tiepolo or Michelangelo. This technique had, in reduced form, the advantages of that a secco work.

In Greco-Roman times, largely encaustic shades implemented in a chilly state were used.

Tempera painting is among the earliest known approaches in mural painting. In tempera, the pigments are bound within an albuminous moderate such as egg yolk or egg white diluted in water.

In 16th-century Europe, oil painting on canvas appeared as a simpler means for mural painting. The advantage was that the art could be finished in the artist’s studio and afterward moved to its destination and there added to the wall or ceiling. Oil paint may be a less adequate medium for murals because of its lack of brilliance in color. Additionally, the pigments are yellowed by the binder or are more easily influenced by atmospheric conditions. The canvas itself is more subject to rapid corrosion than a plaster ground. Many muralists tend to become experts in their favorite medium and application, whether that’s oil paints, emulsion or acrylic paints applied by brush, roller or airbrush/aerosols. Clients will often request a specific style, and the artist may adjust to the proper technique.

A consultation usually contributes to detailed design and design of the proposed mural with a cost quote which the client approves before the muralist starts on the job. The region to be painted may be gridded to coordinate with the design allowing the image to be scaled right measure by step. In some cases, the design is thrown straight onto the walls and traced with pencil before painting starts. Some muralists will paint directly with no prior drawing, preferring the spontaneous procedure.

Once done the mural can be awarded coats of varnish or protective oil glaze to protect the work from UV rays and surface damage.

In contemporary, quick kind of muralling, young fans also use POP clay mixed with adhesive or bond to provide desired models on a picture board. The canvas is later set aside to let the clay dry. Once dried, the canvas and the shape can be painted with your choice of colors and afterward coated with varnish.

As an alternative to an airbrushed mural, digitally printed murals can also be applied to surfaces. Already present murals could be photographed and then be reproduced in near-to-original quality.

The disadvantages of pre-fabricated murals and decals are that they’re often mass-produced and lack the allure and exclusivity of original artwork. They are often not fitted into the individual wall dimensions of the client, and their ideas or wishes cannot be added to the mural as it grows. The Frescography procedure, a digital fabricating method (CAM) invented by Rainer Maria Latzke addresses some of the personalization and dimension restrictions.

Digital techniques are commonly utilized in advertisements. A “wallscape” is a large advertisement on or connected to the exterior wall of a building. Wallscapes can be painted right on the wall as a mural, or printed on vinyl and securely connected to the wall in the manner of a billboard. Although not strictly classed as murals, big scale printed press is often referred to as such. Advertising murals were traditionally painted on buildings and stores by sign-writers, afterward as large-scale poster billboards.

The Mexican mural motion in the 1930s brought new prominence to murals as a political and social tool. Between 1932 and 1940, Rivera also painted murals in San Francisco, Detroit, and New York City. In 1933, he finished a famous set of twenty-seven fresco panels entitled Detroit Industry on the walls of an interior court at the Detroit Institute of Arts. Throughout the McCarthyism of the 1950s, a large sign was put at the courtyard protecting the artistic merit of the murals while attacking his political as “detestable.”

In 1948, the Colombian government hosted the IX Pan-American Seminar to establish that the Marshall program for its Americas. The director of the OEA and the Colombian authorities commissioned master Santiago Martinez Delgado, to paint a mural from the Colombian Congress construction to commemorate the occasion. Martinez chose to make it about the Cúcuta Congress, and painted Bolívar in front of Santander, making liberals angry; so, due to the murder of Jorge Elieser Gaitan the dinosaurs of el bogotazo attempted to burn the capitol, but the Colombian Army stopped them. Years after, in the 1980s, together with liberals in charge of the Congress, they passed a resolution to turn the entire room in the Elliptic Room 90 degrees to put the main mural on the side and ordered Alejandro Obregon to paint a non-partisan mural from the surrealist design.

Northern Ireland contains some of the most popular political murals on earth. ] Nearly 2,000 murals are documented in Northern Ireland since the 1970s. Recently, many murals are non-sectarian, regarding political and social problems such as racism and environmentalism, and several are completely apolitical, depicting children at play and scenes from everyday life.

It was sketched and signed by the artist in April 1942, weeks before his death on the first day of this First Battle of El Alamein. Known as the Bardia Mural, it was created by English artist, private John Frederick Brill.

While on the East Berlin side painting wasn’t permitted, artists painted the Western side of the Wall by the 80s until the fall of the Wall in 1989.

The sometimes detailed artwork was often painted within hours or even days. However, the Western side that the Wall wasn’t protected, so everyone could paint the Wall. After the collapse of the Berlin Wall in 1989, the Eastern side of the Wall also became a popular “canvas” for several murals along with graffiti artists. Orgosolo, in Sardinia, is the main center of murals politics.

It’s likewise common for mural graffiti be used as a memoir. In the publication “Somebody Told Me,” Rick Bragg writes about a series of communities, mainly located in New York, who’ve walls dedicated to the men and women who perished. These memorials, both written word and mural style, provide the deceased to exist in the communities where they lived. Bragg states that the “murals have woven themselves at the fabric of the areas, and the city” These memorials remind people of the deaths caused by inner city violence.
