Get inspired and learn all about the world of fresco!

What does 'fresco' mean?

 Fresco is a painting technique in which pigments are applied to a layer of fresh, damp lime plaster. Once dry, it creates a durable, vibrant image deeply embedded in the wall. This technique has been used for centuries in mural paintings, resulting in beautiful works of art that have stood the test of time.

How to recognise a fresco?

Frescoes have some distinctive features that make them easy to recognise:

• Matte finish: Frescoes have a characteristic matte appearance without gloss.
• Deep colours: The pigments are absorbed into the lime plaster, keeping the colours bright and vibrant.
• Durability: Because the image is embedded in the wall, frescoes are highly durable and withstand the test of time.
• Relief: Sometimes frescoes exhibit a slight texture due to applying the paint on wet plaster.

Famous frescoes

You may have never heard of the term ‘fresco’ before, but you have likely seen an artwork or two where this technique was used. There are many famous frescoes around the world, but here are some of the most iconic:

• The Creation of Adam - Michelangelo (1508-1512): Located on the ceiling of the Sistine Chapel in Vatican City, this is Michelangelo's most famous fresco. It illustrates the biblical story of God giving life to Adam by touching him.
• The School of Athens - Raphael (1509-1511): Found in the Apostolic Palaces in the Vatican, this fresco by Raphael is one of the highlights of Italian Renaissance art. It depicts a group of famous ancient philosophers and scientists, including Plato, Aristotle, and Socrates.
• The Last Judgment—Michelangelo (1536-1541): This fresco, also located on the ceiling of the Sistine Chapel, is at the end of the chapel above the altar. It depicts the Last Judgment, where Christ judges the dead and sends them to heaven or hell.
• The Transfiguration—Raphael (1516-1520): This fresco, located in the Vatican Pinacoteca in Vatican City, depicts the moment when Jesus appears to his disciples in a glorified form on Mount Tabor.

These frescoes are just a few examples of the many beautiful works around the world, illustrating the rich history of this art form.

Techniques and styles in fresco

 Frescoes can incorporate various techniques and styles, including:

• Buon fresco: The most well-known variant, where pigments are applied to fresh, damp lime plaster and embedded into the wall.
• Secco fresco: This technique involves applying pigments to a dry, already hardened lime plaster, resulting in a less durable image.
• Sgraffito: A technique in which layers of different colours are applied to the plaster and then scraped away to create depth and an embossed image.

Modern applications of fresco

While frescoes are often associated with historical works of art, they are also used in modern contexts such as:

Murals in public spaces, such as city centres and community buildings.

Interior decoration in homes and commercial buildings.

Artistic expression in contemporary art galleries and museums.

 Can I make a fresco myself?

 Yes, making a fresco yourself is possible, but it requires some knowledge, skill, and patience. If you're considering doing this, it's important to use suitable materials and follow the correct steps. This way, you'll achieve the best result. Also, ensure you prepare properly before you start, that the surface you use has the required characteristics, and that you allow your work to dry and cure properly.

What materials do I need to create a fresco?

 Making a fresco requires several specific materials:

•  Lime plaster: A mixture of lime, sand, and water that serves as the base for the painting.
• Pigments: Colourful powders mixed with water to make paint.
• Brushes: Various types of brushes are used to apply the paint to the wet plaster.
• Water: To mix pigments and keep the plaster moist during painting.
• Protective gear: Gloves, mask, and safety goggles to protect yourself from the lime and pigments.

Step-by-step how to make a fresco

1.  Preparation of the wall: Apply a layer of fresh lime plaster to a wall or panel and allow it to become slightly damp.
2. Transferring the design: Lightly sketch the desired design onto the moist plaster using charcoal or chalk.
3. Application of the pigments: Mix the pigments with water to a thick, paste-like consistency and apply them to the wet plaster using brushes.
4. Embedding of the pigments: The pigments are absorbed into the lime plaster as it dries, resulting in a durable, embedded image.
5. Finishing: Once the mural has dried, it can be finished with a transparent sealer to protect the colours from dirt, moisture, and damage.

Is the substrate for fresco required to meet specific standards?

Yes, the substrate plays a crucial role in applying a fresco. Ideally, the surface should be porous and absorbent to ensure good adhesion of the lime plaster and pigments. Traditionally, a wall of unplastered brick or rough lime mortar is used as a substrate for frescoes.

The texture and porosity of the substrate help absorb the water from the lime plaster, creating a strong chemical bond. Smooth, non-absorbent surfaces are not suitable for frescoes because the paint cannot adhere properly, which increases the risk of flaking, peeling and fading of the paint.

Are there any special preparations required before I can paint a fresco?

Yes, before you begin painting a fresco, you must make several necessary preparations:

1. Surface preparation: Ensure the surface is clean, dry, and free from dirt, dust, and loose particles. Repair any cracks or damage before applying the lime plaster.
2. Priming: Prime the surface with a thin layer of lime plaster to promote good adhesion of the fresco paint. This also helps to even out any irregularities in the surface and ensures uniform moisture absorption.
3. Preparation of pigments: Prepare your pigments for use by mixing them with water and a small amount of lime. This ensures better spreading and adhesion of the colours to the lime plaster.
4. Correct mixing ratios: Be sure to use the correct mixing ratios for the lime plaster and pigments to achieve the desired colour and texture.
5. Timing: Frescoes should be painted while the lime plaster is still wet to ensure proper paint adhesion. This requires good timing and planning to ensure the lime plaster does not dry too quickly during the painting process.

How long does it take for a fresco to dry?

The drying process of a fresco can vary depending on various factors, including the size of the work, the thickness of the paint layer, the ambient temperature, and humidity. Generally, it takes several days to weeks for a fresco to dry completely.

In the initial stage, the fresh lime plaster absorbs the water used to mix the pigments. As the water evaporates, the lime plaster begins to dry and harden. This process can take several days, depending on the conditions.

Next, the binder, usually lime, reacts with carbon dioxide from the air, forming calcium carbonate, which further cures and hardens the fresco. This process, known as carbonation, can take several weeks to even months, depending on the thickness of the paint layer and environmental conditions.

It's important to be patient during the drying and curing of a fresco, as touching or manipulating the surface too early can cause damage and compromise the integrity of the artwork.

Frescoes are not only an important part of art history but also continue to inspire artists and creatives around the world today. With their unique technique and characteristic appearance, frescoes offer a timeless way to express creativity and tell stories. So what are you waiting for?
