Painting on Canvas – Tips and Techniques

Painting on canvas has been a beloved medium for artists throughout history. Canvas provides a durable and versatile surface that allows artists to create stunning works of art using various mediums, from oils and acrylics to mixed media.

One of the primary advantages of painting on canvas is its portability and flexibility. Unlike painting on walls or other permanent surfaces, canvas artwork can be easily transported and displayed in different locations.

Canvas also comes in a variety of sizes, from small canvases suitable for studies or sketches to large-scale canvases that can create impressive, immersive pieces.

When painting on canvas, artists have the option to work on either stretched or unstretched canvases.

Stretched canvases are pre-mounted on wooden frames, providing a taut surface ready for painting.

Unstretched canvases, on the other hand, offer greater flexibility and can be easily rolled or folded for storage and transportation.

Regardless of the type of canvas used, the process of painting on canvas allows for a unique tactile experience.

The texture of the canvas surface interacts with the brushstrokes and paint application, creating a dynamic interplay between the medium and the support.

This interaction often adds depth and character to the final artwork.

Whether you’re an experienced artist or a beginner, painting on canvas offers an exciting and rewarding creative journey.

With its rich history and versatility, canvas remains a popular choice for artists worldwide, inviting them to explore their creativity and leave their mark on this timeless medium.

Choosing the Right Canvas

When it comes to painting on canvas, selecting the appropriate canvas material and quality can greatly impact your artistic experience and the longevity of your artwork.

As someone who enjoys creating abstract paintings on canvas, I understand the importance of choosing the right surface.

Canvas Materials

The most common canvas materials used for painting are:

1. Cotton Canvas: Considered a traditional choice, cotton canvas is a popular option due to its durability, texture and ability to hold paint well. Cotton canvases can be found in various weights and weaves, offering different levels of absorbency and texture.
2. Linen Canvas: Linen is a premium material that provides a unique, textured surface for painting. It is known for its strength and longevity, making it a favourite among artists seeking a sturdy and long-lasting canvas.
3. Synthetic Canvas: Made from materials like polyester or nylon, synthetic canvases are often more affordable than natural fibres. They can be a good option for beginners or artists working on practice pieces.

Canvas Weights

Canvas weights refer to the density or thickness of the canvas material. The most common weights for painting on canvas are:

• Lightweight: Typically around 4 oz (110 g) or 5 oz (140 g), suitable for studies or practice pieces.
• Midweight: Approximately 7 oz (200 g) or 8 oz (230 g), a versatile option for various painting techniques.
• Heavyweight: About 10 oz (280 g) or 12 oz (340 g), preferred for durability and quality, especially for larger paintings.

As an artist, I prefer using heavyweight cotton canvases for their sturdiness and ability to withstand the rigours of my abstract painting process.

 

Sizing and Stretcher Bars

When choosing a canvas for painting, consider the size and depth of the stretcher bars (the wooden frame).

Thicker stretcher bars provide better support and help prevent warping or twisting, especially for larger canvases. Additionally, canvases over a certain size may benefit from having a centre brace for added stability.

Remember, the depth of the stretcher bars can vary, with options ranging from 18mm (0.71”), 21mm (0.83”) to 38mm (1.5”) and 50mm (2”) or even thicker, depending on the canvas size and your preference.

 

Canvas Keys for Tension Adjustment

One feature that sets good quality stretched canvases apart is the inclusion of “keys” – thin wooden wedges that fit into special grooves in the stretcher bars.

These keys serve an essential purpose: they allow you to adjust the tension of the canvas over time.

As you work on a stretched canvas, the canvas fibres can gradually loosen or tighten due to factors like changes in humidity, temperature or the application of paint and mediums.

This natural shifting can cause the canvas to become too loose or too taut, potentially leading to issues like sagging or excessive tension.

With canvas keys, you have the ability to maintain the optimal tension on your canvas throughout the painting process.

If you notice the canvas becoming too loose, you can gently tap the keys deeper into the grooves, tightening the surface.

Conversely, if the canvas is too taut, you can carefully release the keys, allowing the canvas to relax and regain its ideal tension.

This simple yet effective mechanism ensures that your canvas remains in prime condition, providing a stable and consistent surface for your brushstrokes and compositions.

It’s a feature that many professional artists appreciate, as it helps to preserve the integrity of their artworks and minimizes the risk of issues like buckling or warping over time.

When selecting stretched canvases, take note of whether they come equipped with these handy canvas keys. It’s a small detail that can make a big difference in the longevity and quality of your paintings on canvas.

With a bit of woodwork experience, you can make your own stretcher bars. I prefer the beaded edge rather than bevelled.

Bevelled Stretcher Bar Edges

When examining high-quality stretched canvases, you’ll notice that the stretcher bars (the wooden frames) often feature a subtle yet essential design element: bevelled or lifted edges.

Instead of having sharp 90-degree angles, these stretcher bars incorporate a slight bevel or lift on the inner sides.

This seemingly minor detail serves several important purposes:

1. Preventing Canvas Abrasion: The bevelled edges create a small gap between the canvas and the inner edge of the stretcher bars. This gap ensures that the painted surface of the canvas does not directly rub against the wooden frame, reducing the risk of abrasion or damage to your artwork.
2. Improved Air Circulation: By creating space between the canvas and the frame, the bevelled edges allow for better air circulation behind the canvas. This improved airflow can help prevent issues like mould or mildew, which can occur when moisture becomes trapped behind the canvas.
3. Enhancing Depth Perception: The subtle lift or bevel on the stretcher bars can also contribute to the overall depth perception of your painting. By creating a slight separation between the canvas and the frame, the artwork appears to float ever so slightly, enhancing the illusion of depth and dimensionality.

When selecting stretched canvases for your artwork, paying attention to these bevelled edges is essential.

Not only do they provide practical benefits in terms of protecting your paintings and allowing proper air circulation, but they also contribute to the overall presentation and longevity of your pieces.

Good quality canvas manufacturers understand the importance of these design details, ensuring that their products meet the highest standards for both function and aesthetics.

By investing in stretched canvases with bevelled stretcher bars, you can have peace of mind knowing that your artworks are well-protected and displayed to their full potential.

Large Unstretched Canvas Painting

One of my preferred methods for creating abstract paintings is working on large unstretched cotton canvases, often measuring around 1.6 x 2.1 meters (5.25 x 7 feet). The decision to use unstretched canvases for these larger pieces is primarily driven by space considerations, particularly in terms of storage.

Unstretched canvases offer the flexibility to be rolled or folded, allowing me to efficiently store and transport these expansive artworks, which can be challenging with pre-stretched canvases of such substantial sizes.

Preparing the Canvas Surface

Before you start painting on canvas, properly preparing the surface is crucial for achieving the best results. Skipping this step can lead to issues such as paint absorption, adhesion problems, or an uneven surface texture.

Importance of Priming and Gessoing

Priming or gessoing is an essential step in the process of painting on canvas. It serves several purposes:

1. Sealing the Canvas: The primer or gesso seals the canvas fibres, preventing the paint from being absorbed unevenly into the fabric.
2. Creating a Smooth Surface: A properly primed canvas provides a smooth and even surface for your brushstrokes, ensuring a consistent application of paint.
3. Improving Adhesion: The primer or gesso acts as a binding agent, helping your paint adhere better to the canvas surface.
4. Protecting the Canvas: A good primer or gesso can also help protect the canvas from potential damage caused by the acidic properties of certain paints or mediums.

As an artist who works extensively with canvas, I always apply two to three coats of gesso to prime the surface before starting a new painting. This practice ensures a reliable foundation for my abstract compositions.

Types of Primers and Gesso

When preparing your canvas for painting, you’ll encounter various types of primers and gesso:

1. Acrylic Gesso: One of the most common options, acrylic gesso is a versatile primer that can be used with both oil and acrylic paints. It dries quickly and provides a smooth, absorbent surface.
2. Oil-based Primers: These primers are specifically formulated for use with oil paints. They offer a slightly more absorbent surface than acrylic gesso and can enhance the depth and richness of oil colours.
3. Tinted or Coloured Gesso: In addition to white gesso, tinted or coloured gesso is available, allowing you to start with a coloured surface that can influence the overall tone of your painting.

Depending on your preferred medium (oils, acrylics or mixed media) and the desired surface texture, you can choose the appropriate primer or gesso for your painting on canvas.

Here’s an interesting article about 9 Things You Should Know About Gesso and How You Should Use It.

Application Techniques

When applying the primer or gesso to your canvas, several techniques can be employed:

1. Brush Application: Using a wide, flat brush, apply the primer or gesso in thin, even coats, allowing each coat to dry completely before applying the next.
2. Roller Application: For larger canvases, a small foam roller can be an efficient tool for achieving a smooth, even application of the primer or gesso.
3. Textured Application: If you desire a more textured surface, you can experiment with applying the primer or gesso using palette knives, sponges or other tools to create unique surface patterns.

Remember, properly preparing the canvas surface is a crucial step that should not be overlooked. It lays the foundation for a successful painting experience and helps ensure the longevity and quality of your artwork on canvas.

Painting Mediums and Techniques for Canvas

Once you’ve prepared your canvas surface, it’s time to explore the various mediums and techniques that can be used for painting on canvas. The versatility of canvas as a support allows for a wide range of artistic expression.

Oil Painting on Canvas

Oil paints have been a traditional choice for painting on canvas for centuries. The rich, buttery consistency of oil paints lends itself beautifully to the textured surface of a canvas, allowing for smooth blending, impasto techniques and a wide range of brushwork.

When working with oils on canvas, it’s important to consider factors such as drying times, mediums and proper canvas priming.

I often use a combination of oil paints and mediums to create layered and textured abstract compositions on canvas.
