Different muralists tend to become experts in their preferred medium and application, whether that be oil paints, emulsion or acrylic paints applied by brush, roller or airbrush/aerosols. Clients will often ask for a particular style and the artist may adjust to the appropriate technique.
A consultation usually leads to a detailed design and layout of the proposed mural with a price quote that the client approves before the muralist starts on the work. The area to be painted can be gridded to match the design allowing the image to be scaled accurately step by step. In some cases the design is projected straight onto the wall and traced with pencil before painting begins. Some muralists will paint directly without any prior sketching, preferring the spontaneous technique.
Once completed the mural can be given coats of varnish or protective acrylic glaze to protect the work from UV rays and surface damage.
CAM designed Frescography by Rainer Maria Latzke, digitally printed on canvas
As an alternative to a hand-painted or airbrushed mural, digitally printed murals can also be applied to surfaces. Already existing murals can be photographed and then be reproduced in near-to-original quality.
The disadvantages of pre-fabricated murals and decals are that they are often mass produced and lack the allure and exclusivity of an original artwork. They are often not fitted to the individual wall sizes of the client and their personal ideas or wishes can not be added to the mural as it progresses. The Frescography technique, a digital manufacturing method (CAM) invented by Rainer Maria Latzke addresses some of the personalisation and size restrictions.
Digital techniques are commonly used in advertisements. A "wallscape" is a large advertisement on or attached to the outside wall of a building. Wallscapes can be painted directly on the wall as a mural, or printed on vinyl and securely attached to the wall in the manner of a billboard. Although not strictly classed as murals, large scale printed media are often referred to as such. Advertising murals were traditionally painted onto buildings and shops by sign-writers, later as large scale poster billboards.
Many people like to express their individuality by commissioning an artist to paint a mural in their home, this is not an activity exclusively for owners of large houses. A mural artist is only limited by the fee and therefore the time spent on the painting; dictating the level of detail; a simple mural can be added to the smallest of walls.
Private commissions can be for dining rooms, bathrooms, living rooms or, as is often the case- children's bedrooms. A child's room can be transformed into the 'fantasy world' of a forest or racing track, encouraging imaginative play and an awareness of art.
The current trend for feature walls has increased commissions for muralists in the UK. A large hand-painted mural can be designed on a specific theme, incorporate personal images and elements and may be altered during the course of painting it. The personal interaction between client and muralist is often a unique experience for an individual not usually involved in the arts.
Public commissions of murals in schools, hospitals and retirement homes can achieve a pleasing and welcoming atmosphere in these caring institutions.
