The blank canvas is a dual opportunity and obstacle in the realm of art. While it allows for boundless imagination, it also presents technical uncertainties. A frequent concern among artists, particularly novices, is: “Is it necessary to prep my canvas before painting?”
The short answer to this question is: Yes. But to fully appreciate the importance of priming your canvas, let’s dive deeper into the subject.
Understanding Priming
Priming, also known as sizing, is the process of preparing the painting surface with a specific solution to make it receptive to the painting medium, usually acrylic or oil paints. This process not only smooths the canvas and makes it easier to work on, but also prevents paint from soaking into the canvas.
Why Prime a Canvas?
Priming creates a barrier between the paint and the canvas, preventing the paint from directly contacting the canvas fibers. This is critical because the oil in paint can cause canvases, particularly those made of cotton or linen, to rot over time.
Furthermore, priming helps to enhance the vibrancy of the colors. Unprimed canvases tend to absorb the paint, reducing the intensity of the colors. Therefore, if you want your colors to stand out and pop, priming your canvas is a must.
How to Prime a Canvas?
The most popular material for priming canvas is Gesso, a white paint mixture consisting of a binder mixed with chalk, gypsum, pigment, or a combination of these. Gesso is typically applied in thin layers over the canvas, using a brush or a roller, and allowed to dry completely before the painting process begins.
Even pre-stretched canvases that are marketed as ‘pre-primed’ can benefit from an additional layer of gesso, especially if you’re looking for a smoother painting surface.
To Prime or Not to Prime?
While priming is generally recommended, not all artists prime their canvases, and that’s okay. Some artists choose to work on raw, unprimed canvas for the specific texture and absorbency it offers. However, if you’re working with oil paints or want to ensure the longevity and vibrancy of your artwork, priming your canvas is an important step you shouldn’t skip.
Remember, art is all about experimentation and finding what works best for you. Don’t be afraid to try different techniques and see the results for yourself.
