Artists have developed street art techniques in recent years. Indeed, street art refers to all forms of street art. Many techniques have been identified: street installation, stenciling, yarn bombing, sticker, graffiti, mosaic, video projection, flash mobbing, or even tape art.

1. Graffiti

New York in the 1970s was a city in crisis in a country in crisis, where poverty, racial segregation, and gang wars combined. In this degraded context, the popular side of urban art emerges graffiti.

According to the dictionaries, graffiti is: "An inscription or a drawing scribbled by passers-by on a wall or a monument."

This definition does not even recognize graffiti as an art.

In reality, graffiti is, above all, a means of expressing yourself, which consists of affixing your mark, your signature, your blaze on any surface to which the paint adheres.

Like all other street artists, graffiti artists use the street as a vector of communication and impose their productions in the eyes of passers-by. Indeed, the graffiti "captured" on a canvas is no longer graffiti: it has lost its ephemeral and public character.

Over time, graffiti artists invented new techniques, which are now the main and most common: spray paint and indelible paint.

2. The stencil

We all know stencils, and we have certainly used them in our life. From kindergarten to interior decoration, this technique is very widespread and has the advantage of being easy to use. In addition, the rendering is generally successful without having the soul of an artist.

In urban art, this type of tool is made from a homemade stencil made by the street artist. Usually designed using paper or cardboard, the stencil creates a mural that can be easily and quickly reproduced on the street.

After creating the stencil, the desired design is cut from the chosen medium and can be reproduced by using spray paint or roller paint. The painter Banksy is one of the most famous graffiti artists using this system. He uses it very often to make his paintings.

3. The art sticker

Messages displayed using stickers

Sticker art is a type of street art in which an image or message is displayed publicly using stickers. These stickers can promote a political agenda or commentary on a social or political issue. Many different types of decals (stickers) are used to create sticker art.

This form of street art allows graffiti to be placed instantly in any accessible location with a much lower risk of apprehension and causing less damage to the targeted surface than with other types of street art.

Many sticker art artists also trade with other sticker art artists to distribute their stickers around the world, and their works will often be pasted in places they have never visited. Sometimes, exchanges are arranged in person (often through social networking sites) or online.

4. Installations

Street installation is a growing trend within the urban art movement. While conventional Street Art and graffiti are done on surfaces and walls, the street installation uses 3D objects and space to interfere with the urban setting.

Generally, street installations are not allowed. Once the sculpture is created, it is left in place by the artist.

5. Yarn bombing

Yarn bombing or "street knitting" artistic movement at the crossroads of land art and especially Street Art renews it with a pleasant touch of humor. This form of urban art mainly uses the technique of knitting with multiple colors of threads. He invests the statues, the trees, in reality, anything in the street which could be covered with knitting. The main objective is to dress public places by humanizing them and trying to catch the eye of passers-by. Yarn bombing remains illegal when it is not a request from the public authorities.

6. Tape art

Tape art is a technique that uses adhesive tapes of different types to create works. This kind of street art is considered ephemeral due to the quality of the ribbons.

There are also two subcategories of tape art:

Brown Tape Art: the works are made from large brown tape, which can be found in particular to close boxes. Transparent tape is also used to create contrasts.

Duct Tape Art: duct tape, generally used in DIY, makes up the works of duct tape art. This material is well known under the name of 3M tape; this material holds very well and is resistant to different outdoor temperatures.

7. Poster

A poster is a kind of graffiti, more specifically classified as "street art." Posters are usually handmade or graphics printed on thin paper. Thus, it can be seen as a work of art that is installed in the streets.

8. Mosaic

The mosaic technique consists of creating a work by assembling different pieces of different materials. Thus, artists can form faces, words, and various colors thanks to the different components that they associate with each other.

9. Flash mobbing

A large group of people who suddenly gather in a public place perform an unusual action for a brief moment, then disperse. The term "flash mob" generally applies only to telecommunications or social networks gatherings.

The term does not, in general, apply to events organized by public relations firms or which are advertised. However, we can also say that it is a mass public spectacle.

10. Luminous graffiti

It is therefore practiced with fluorescent ink. To reveal this graffiti, you need to use ultraviolet lighting, but others are simply revealed in the dark thanks to a special gelatin filter. In the daylight, you can't see anything; in the dark, the lettering shoots out from the wall.
