Do I Need to Prime my Canvas Before Painting with Acrylics?
This question is very common! The answer actually depends on the canvas that you purchase. Most, if not all, canvases that you buy at your typical craft stores are already primed for acrylic painting. If the canvas is a bright white color, it’s ready to go! I don’t prime my canvases because I buy them pre-primed.
How do I know if it has primer on it already?
Look at the label on your canvas that you bought or are about to buy. It might say something like “Titanium Acrylic Gesso Primed”. This means that the manufacturer applied gesso that is bright titanium white! It is ready to be painted on, no primer required.
What is Gesso?
If you are referring to the bright white coating on the canvas, that is actually called “Gesso”! Gesso is a combination of white paint and binders and it is applied to a surface such as canvas. Canvas that is not “gessoed” is very absorbent. Thus, if you were to paint on that surface, the paint would just soak in and not glide easily.
You can apply Gesso to other surfaces that you don’t want to be absorbent such as wood!
What canvases do you get?
I buy these bulk packs at Michael’s. I like frugal and I paint a lot. In that sense, these bulk canvases are great for the type of painting tutorials I have on this website! They are pre-primed and ready to be painted on.
Where can I get gesso?
Gesso can be bought at any arts and crafts store or Amazon. I hardly use it because I buy canvases that are primed and ready to go. If you are interested in priming a surface with gesso, I like the Liquitex Gesso.
Can I apply the gesso on a canvas that is already “primed”?
Yes! In fact some artists prefer a different smoothness or want to experiment with different texture surfaces on the canvas. You can also apply a different color gesso like black!
Priming your canvas by applying a layer or two of gesso to the surface will help the colours in your work really stand out. When using oil colour on canvas, and the canvas is poorly primed, the oil may sink into the canvas and leave dull patches on the surface of your painting.
Priming your canvas protects your canvas from rotting. It also means your paint will sit better on the surface and not sink into the canvas. When it comes to oil colour, priming can help avoid dull patches in your finished work and make the colours stand out. Priming gives you an even ground to work on.
If you don't prime or gesso your canvas it is likely to rot over time when directly in contact with your paint. What is oil painting primer? For oil paints, you can use an oil painting primer, a thixotropic or an oil-modified alkyd resin medium instead of gesso.
Canvas can be bought in primed or unprimed form. Primed canvas refers to canvas that has already been coated with a primer, such as gesso.Unprimed canvas is canvas that has not been coated. In general you will want to paint on a canvas that has been primed, because this means that it will more easily accept the paint.
Canvas, by its very nature, is not a smooth surface due to its weaves. If your canvas is raw you must prime it with gesso a few times before painting otherwise all your painting effort will be a complete waste of time and money. Even if your canvas is pre-primed you should consider applying additional layers of gesso.
PVA Glue Primer: A mixture of white PVA (polyvinyl acetate) glue and water can serve as a DIY primer. Mix the glue with water to achieve a consistency similar to gesso and apply it to your surface. Allow it to dry thoroughly before painting.
For best results, apply a minimum of 2 coats of gesso and sand in-between. Subsequent layers of gesso will produce an even smoother painting surface. Follow the directions provided with the product that you are using for the recommended number of coats.
This is a fast-drying, flexible, non-yellowing primer for mixed media. Gesso primer enables the paint to stick to the surface and provides a matt finish which can be sanded down for a smoother finish. Once applying gesso primer, the canvas will be ready to paint on within a matter of hours.
If canvas or paper is in contact with the oil in oil paint or oil primer, it slowly corrodes the canvas fiber. Use either rabbit skin glue (RSG) or acrylic polymer to seal it. Unprimed canvas is better especially for animal rights advocates, as they do not need to use RSG or any other product to prepare the surface.
Without this process, the canvas would absorb too much paint, have dull patches, or sag too easily. Most of the canvases that you can purchase are pre-primed so you don't have to worry about any of this.
Priming your canvas is essential. This is true even if you're starting on a pre-stretched and primed canvas from the store. It seems to me that the acrylic paint “sits” better on a good priming.
Gesso prepares (or "primes") the surface for painting, making the surface slightly textured and ready to accept acrylic paint. Without gesso, the paint would soak into the weave of the canvas. The word gesso is a noun, but many artists also use it as a verb.
The ground is a protective and a structural layer that adds stability to the paint film, no matter if it's oil or acrylic. Painting on unprimed canvas has archival and structural drawbacks that you should be aware of.
The answer actually depends on the canvas that you purchase. Most, if not all, canvases that you buy at your typical craft stores are already primed for acrylic painting. If the canvas is a bright white color, it's ready to go!
Unpainted wood and drywall can pose huge adherence problems for coatings without primer. With fresh drywall, the substrate actually absorbs a coating really well, like a sponge. However, because it absorbs so well, without a primer coat, you'll experience uneven coverage, especially along drywall seams.
