Fresco painting is a technique that involves applying water-based pigments to wet plaster, typically on wall surfaces. The colours are made by grinding dry-powder pigments in pure water, and as the plaster dries, the painting becomes an integral part of the wall. This method has been used for millennia and is most associated with mural paintings from various historical periods, including the Minoan civilisation and the Renaissance in Europe. The Italian word 'fresco' is derived from the Italian adjective 'fresco', meaning 'fresh'.

What You'll Learn
Fresco paintings are typically supported by walls
The use of walls as a support for fresco paintings has a long history, dating back to ancient civilizations such as the Minoan civilization and the Renaissance in Europe. During the Renaissance, fresco painting flourished, with artists such as Michelangelo and Raphael creating renowned works using this technique. The Sistine Chapel ceiling, for example, is a famous example of a fresco painting supported by a wall.
The preparation of the wall for a fresco painting involves applying several layers of a mixture of lime, sand, and water to create a plaster surface. This process is crucial, as it ensures the plaster will hold its moisture for many hours, allowing the artist to work with the wet plaster. The artist then transfers the design onto the wall and applies the pigments mixed with water directly to the plaster.
The unique aspect of fresco painting is that there is no separate painting medium or binder; instead, the lime in the plaster acts as the binding agent. This gives the colours great permanence and resistance to ageing. However, it also demands technical skill from the painter, as they must work quickly while the plaster is still wet.
While walls are the traditional support for fresco paintings, other surfaces such as papyrus, hot wax, or ivory have been suggested. However, these alternatives pertain to different art forms or mediums and are not suitable for true fresco techniques. The wall, with its plaster surface, remains the foundational element that defines the fresco art form.

Walls allow for paint to bind chemically to the plaster
The typical support for a fresco painting is a wall. Fresco paintings are created by applying water-based pigments to wet plaster, which is usually applied to wall surfaces. The pigments are absorbed by the wet plaster, and as the plaster dries, it chemically reacts with the pigments, binding the paint to the wall. This process, known as "buon fresco" or "true fresco", results in a durable and long-lasting artwork that becomes an integral part of the wall.
The word "fresco" is derived from the Italian adjective "fresco", meaning "fresh". This technique has been used since antiquity and is closely associated with Italian Renaissance painting. The process involves applying a thin layer of wet, fresh plaster, called the "
The chemical makeup of the plaster eliminates the need for a binder, as the pigment mixed with water sinks into the intonaco, which becomes the medium holding the pigment. As the plaster dries in reaction to the air, it undergoes a chemical reaction that fixes the pigment particles in the plaster. This process gives the colours great permanence and resistance to ageing, as they are an integral part of the wall rather than a superimposed layer of paint.
The buon fresco technique is considered the most traditional and typical method of fresco painting. It is a challenging process as it requires the artist to work quickly while the plaster is still wet, and any mistakes cannot be corrected by overpainting. Instead, corrections must be made on a fresh coat of plaster or by using the "secco" method, which involves painting on dry plaster.
The secco method, or "fresco secco", is less permanent and durable than buon fresco. It requires the use of a binder, which can make the artwork less stable over time. The surface of a secco painting is typically rougher than that of a buon fresco, as the inconsistent surface aids in the binding of the paint. This method is often used to touch up or add details to a buon fresco.

Buon fresco is the most typical and traditional technique
Fresco is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as a vehicle for the dry-powder pigment to merge with the plaster, and as the plaster sets, the painting becomes an integral part of the wall. The word "fresco" is derived from the Italian adjective "fresco", meaning "fresh".
Buon fresco, or true fresco, is the most typical and traditional fresco technique. It involves painting with pure powdered pigments, mixed with water, directly onto wet plaster. As the plaster cures, the pigment is absorbed into the surface, and the water evaporates, bonding the pigments into the matrix of the plaster. This process is called "buon fresco".
The plaster used in buon fresco is typically a mixture of lime, sand, and water, applied in several layers to a wall or ceiling. The artist must work quickly, as the plaster dries within a few hours, and mistakes cannot be corrected by overpainting. Instead, corrections must be made on a fresh coat of plaster or by using the secco method.
Buon fresco is considered the most durable fresco technique, and its longevity is evident in the prehistoric cave paintings in the Lascaux Caves and the ancient frescoes of Pompeii and Herculaneum. The technique was also favoured by Renaissance painters such as Michelangelo and Raphael, who created impressive and enduring works such as the Sistine Chapel ceiling and "The School of Athens".
The preparation for a buon fresco is meticulous and time-consuming. First, a rough underlayer called the arriccio is added to the entire area to be painted and allowed to dry for several days. The artist may sketch their composition on this underlayer using a red pigment called sinopia. Then, on the day of painting, a thin, smooth layer of fine plaster called intonaco is added to the amount of wall expected to be completed in one session. This area is called a giornata, or "day's work".

Buon fresco involves applying water-based pigments to wet plaster
The typical support for a fresco painting is a wall. Fresco involves applying water-based pigments to wet plaster, and this method has been used for millennia. Fresco is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as the vehicle for the dry-powder pigment to merge with the plaster, and as the wall dries and sets, the pigment particles become bound or cemented along with the lime and sand particles.
The buon fresco technique is difficult to create because of the deadline associated with the drying plaster. The artist must work fast while the plaster is wet, and mistakes cannot be corrected by overpainting. This must be done on a fresh coat of plaster or by using the secco method. The secco technique is often used on buon frescoes to touch up or add details.
The process of painting a buon fresco starts with the application of a rough underlayer called the arriccio to the whole area to be painted. This is allowed to dry for several days. Artists often sketch their compositions on this underlayer in a red pigment called sinopia. The final, smooth coat (intonaco) of plaster is then trowelled onto as much of the wall as can be painted in one session. The artist then has only a limited time to paint before the plaster dries.

Fresco secco involves painting on already dried plaster
Fresco is a technique of mural painting executed upon freshly laid ("wet") lime plaster. Water is used as a vehicle for the dry-powder pigment to merge with the plaster, and as the plaster sets, the painting becomes an integral part of the wall. The word fresco (Italian: affresco) is derived from the Italian adjective "fresco", meaning "fresh".
Fresco secco, or "dry fresco", involves painting on already dried plaster. This technique does away with the complex preparation of the wall with wet plaster. Instead, dry, finished walls are soaked with limewater and painted while wet. The colours do not penetrate into the plaster but form a surface film, like any other paint.
Secco is useful for detailed painting and for retouching true fresco. For example, blue was a particular problem in true fresco, as neither azurite blue nor lapis lazuli would work well in wet fresco. Skies and blue robes were often added a secco. Secco techniques also allowed for a broader range of pigments to be used.
To prepare a wall for a secco painting, the intonaco is laid with a rougher finish and allowed to dry completely. The painter then rubs the intonaco with sand to give it a key. The painter can then proceed much as they would on a canvas or wood panel.
The stability of secco paintings depends on the presence of a binding medium, such as egg, oil, gum, or glue, mixed with the pigments to adhere them to the wall surface.

Frequently asked questions
A wall. This is because fresco painting is done on plaster surfaces, allowing for the paint to bind chemically when the plaster dries.
Buon Fresco, or true fresco, is the most typical and traditional technique. The ground pigments are added to water and painted directly onto wet lime or gypsum plaster without the use of a binder.
In the Buon Fresco technique, artists apply water-based pigments onto fresh, wet plaster. In contrast, Fresco Secco involves painting on already dried plaster, which is less permanent.
The time an artist has to paint a fresco depends on the plaster drying time. Artists must prepare only enough wet plaster that they are able to paint in a single day.
