How to Use Gesso on a Canvas

Gesso? What is it?

Most beginners in painting may be unfamiliar with the word “gesso.” It’s a highfaluting term that could leave a novice dumbfounded. But, don’t fret. In this post, I’ll try to shed light on this and hopefully, we can understand what gesso is all about.

Encyclopaedia Britannica defines gesso (pronounced ‘jesso’) as:

“a fluid white coating, composed of plaster of paris, chalk, gypsum, or other whiting mixed with glue, applied to smooth surfaces such as wood panels, plaster, stone, or canvas to provide the ground for tempera and oil painting or for gilding and painting carved furniture and picture frames.”

Basically, gesso is a substance used to prepare or prime a canvas before you can use it in painting. It was traditionally used by oil painters so the oil paints would adhere to the canvas. Gesso is used to protect the canvas fibers, smoothen the surface, and give flexibility to the canvas.

Is there a difference between an oil gesso and an acrylic gesso? Yes, their ingredients. Traditional oil gesso, also called glue gesso, contains an animal glue binder (usually rabbit-skin glue), chalk, and white pigment. Acrylic gesso is made of an acrylic polymer medium (binder), Calcium carbonate (chalk), a pigment (Titanium white), and chemicals for flexibility and longer life.

Acrylic gesso doesn’t contain glue since acrylic paints is not corrosive, unlike oils. The glue in the glue gesso is absorbed by the fibers of the canvas which protects it from the corrosive nature of oil paints. Many artists use acrylic gesso because of its versatility, quick drying time, convenience, flexibility, and ease of use. Some artists claim that it can be used as ground when painting in oil but some argue that the flexibility of the acrylic gesso will cause the oil paint to crack over time.

An acrylic painter could choose not to use acrylic gesso if he wants the staining effect of acrylic paints on canvas. For beginners, it’s better to prime the canvas first, or use a pre-primed canvas since you are still practicing your painting skills. CanvasLot offers pre-primed canvas in various sizes so you won’t go into the trouble of priming your canvas.

If you are a beginner in oil painting, you can use acrylic gesso but just make sure that the canvas has been properly sized. If you are creating a portrait, or planning to create a masterpiece or something like an heirloom to your family, it’s better to use the oil gesso since the oil paint will stick better to it than to an acrylic.

You can buy acrylic gesso in most art supplies shops and it is available in artist quality and student quality. As with other art supplies, the artist quality acrylic gesso is more expensive and has higher quality than the student gesso. For priming a canvas, use the artist quality gesso.

Tips for Caring and Handling Acrylic Paintings

Acrylic paints were introduced in the 1950s, much later than oils, but museums, galleries, and art collectors have included many acrylic paintings in their collections. Artists have experimented and used acrylics on canvas for its versatility of use and quick drying time. The properties of acrylic paints differ from oils so the maintenance and caring for acrylic paintings is different from oil paintings. Since acrylic paint is relatively new compared to oil paints which have been used in art for centuries, people are just starting to know its aging characteristics. For now, the best way to preserve and lengthen the life of acrylic paintings is by preventive care.

Here are the tips for caring and handling acrylic paintings:

Cleaning
Currently, there is no concrete guideline how to clean an acrylic painting. Below are just suggestions that you can do at the moment.

1. Use a clean towel or a feather duster and lightly remove the dirt on the surface of the painting. Acrylic paintings gather dust more easily than any other medium so you may have to dust them frequently.

2. If you want to keep off the dust, put the painting in a protective frame. Acrylic paintings have electrostatic charges on the surface which attracts dust and a protective frame will prevent dust from accumulating.

3. Don’t use water, soap, or household cleaners when cleaning acrylic paintings. Most cleaning agents have ammonia which can damage your painting. When you use cleaning sprays in your house, make sure that your acrylic painting is not nearby when you are cleaning to avoid excess droplets of the spray go to the paintings.

Maintenance

1. Keep acrylic paintings away from direct or extreme heat, cold, and humidity. Acrylic paint becomes soft around 60° so display your paintings far from ovens, stoves, heating lamps, or any other source of heat inside the room.

2. Don’t touch the surface of an acrylic painting. Your fingernail may accidentally leave a dent or put extra pressure on the painting which will lessen the value of the piece.

3. Mold growth is a common issue in acrylic paintings. There is no solution for it yet that would retain the original paint of the piece. The best way to lessen mold on the surface is to hang the painting in a room where there is less humidity.

Transporting

1. Put the acrylic painting in an effective packing case that would protect it from damage. According to this website, a packing case should be able to do the following:

Support the painting, insulation and cushioning foams
Protect the contents from impact and puncture without serious distortion
Maintain a sealed environment
Protect against intrusion of moisture
Provide handles for lifting and moving
Survive a multi-venue tour without compromise of any of the above functions

2. Include instructions for unpacking and repacking outside the container. The recipient may not know the proper way of unpacking the painting so proper instructions should be provided by the sender. These instructions are important especially if there is a dispute about any damage caused by shipping, unpacking, or repacking of the painting.

3. If you have to transport the painting by rolling it, here are tips:

Allow enough time for the painting to be completely cure.
Put a polyethylene plastic onto the surface of the painting before rolling.
Roll and unroll the painting at room temperature. A heated room will melt the paint while a cold room will cause cracking.
Roll the painting loosely and evenly to prevent adhesion or ferrotyping.
Once packed, secure the painting with a tape.

Acrylic Artists Who Made Their Mark in History

Campbells_Soup_Cans_Warhol — Campbell’s Soup Cans, 1962

Many artists use acrylics in painting due to its fast-drying qualities and versatility. Unlike oil paints which take decades to fully dry, an acrylic painting can dry in just hours. You can also use different painting styles when using acrylics and you can use it on canvas, paper, wood, glass, or even stone.

Here are the famous artists who used acrylics in their art works:

1. Andy Warhol (August 6, 1928 – February 22, 1987). Andy Warhol was a celebrated American artist and was considered as one of the leading figures in Pop Art. He was the one who started the use of everyday items such as soup cans, soft drink bottles, and dollar bills as subjects in his paintings which were then displayed in museums. Aside from using mundane objects, he was fascinated in the entertainment industry and used famous celebrities and even political figures as subjects. He created portraits of Marilyn Monroe, Elvis Presley, and Jackie Kennedy.

2. Kenneth Noland (April 10, 1924 – January 5, 2010). Kenneth Noland was an American abstract painter. He was known for his geometrical themes called Chevrons and Stripes and circular motifs which are called Target paintings. Noland was known as one of the leading figures in the Color Field painting style in the US. In the 1950s, he was able to meet influential people in the art scene such as abstract expressionists Helen Frankenthaler and Morris Louis. They greatly affected the artistic direction of his career. He started using Frankenthaler’s technique in stain painting wherein he used a thinned acrylic paint on unprimed canvas. These three painters led the formation of the Color Field painting style.

3. Robert Motherwell (January 24, 1915 – July 16, 1991). Robert Motherwell was an American abstract painter. In the 1960s, he used acrylics in painting large-scale canvases. Primarily using oils, he switched to acrylics because of its quick drying time. The Elegy of the Spanish Republic is considered as one of his most important works. It is a series of abstract paintings using black and white paint in bold movements and strokes.

4. David Hockney (born July 9, 1937). David Hockney is an English painter and draftsmen, and a founding member of the British Pop Art movement in the 1960s. He is one of the most famous British artists. His visit in California inspired him to paint swimming pools and the urban landscape using acrylics. During that time, he developed his own style of painting called naturalistic-realistic painting. One of his famous works includes The California Collector (1964) which depicts a swimming pool in LA.

5. Roy Lichtenstein (October 27, 1923 – September 29, 1997). Roy Lichtenstein was an American pop artist who used comic strips and advertisements as inspirations in his art works. He was famous for creating bright and graphic images which parodied pop culture. In one of his most significant works, Drowning Girl, he used both oil and acrylic (Magna) paints and the piece was considered as a “masterpiece of melodrama.”

Jackson Pollock: Master of the “Drip” Technique

“It is only when I lose contact with the painting that the result is a mess. Otherwise there is pure harmony, an easy give and take, and the painting comes out well.”
– Jackson Pollock

Jackson Pollock is best known for revolutionizing the world of modern art with his unique abstract techniques, specifically the drip painting technique. Born in January 28, 1912, Paul Jackson Pollock, more popularly known as Jackson Pollock was a major influence in the abstract expressionist movement. He studied under Thomas Hart Benton, an esteemed painter and muralist, before exploring abstraction expressionism. Pollock died in an alcohol-related car accident in December 1956. He was 44.

The “Drip” Period

In 1936, Pollock attended a workshop by Mexican muralist David Alfaro Siqueiros in New York City and this is where he was introduced to the use of liquid paint. He used paint pouring as a technique and he began painting with his canvas laid down on the floor and the “drip” technique was born.

The “drip” technique is a combination of Pollock’s body movements, flow of paint, gravity, and paint absorption. It was a technique which merges the controllable and uncontrollable factors in painting. Pollock moves around his canvas while dripping, pouring, splattering paint onto it until he’s satisfied with the result.

Pollock’s paintings became famous during the “drip” period, between 1947-1950. The Life magazine published an article on Pollock in 1949 which asked, “Is he the greatest living painter in the United States?” that made him distinguished in the art world. His exhibition in the sames year at the Betty Parsons Gallery sold out and he instantly became the best paid avant-garde painter in the US.

Here are some of Pollock’s most famous paintings during the “Drip” period:

Full Fathom Five is one of Pollock’s earliest drip paintings. The top layers consist of poured skeins of house paint, creating a lace-like image. Pollock used a brush and palette knife to build up the underlayer of the painting.

Number 1 is the masterpiece of the drip technique. This is one among Pollock’s largest works, pulsing with energy, with an intricate web of hues that suggests speed and force.

Composition (White, Black, Blue and Red on White), 1948 is a great example of Pollock’s “drip” technique or flung paint. When Pollock was creating this masterpiece, he placed his canvas on the floor and painted in a rhythmic, undulating style. This piece represents pure abstraction, a painting with no focal point and thus making all areas of the painting important.
