Priming a canvas – when does it make sense?

For most applications with acrylic or oil paints, priming is highly recommended. It protects the canvas fabric – usually cotton or linen – from paint media soaking in and creates an even surface. Paints adhere better and look richer and more brilliant.

Many ready-stretched canvases already come with a layer of gesso applied at the factory and can be painted on straight away. Nevertheless, some artists like to apply extra layers to influence the texture or paint application individually.

In certain cases – for example with experimental techniques or mixed media work – it can also be interesting to work without primer on purpose. This creates quite distinctive effects and surfaces. If you choose this approach, be aware that the behaviour of the paint and the nature of the canvas differ significantly from primed versions.

Conclusion: for classic acrylic or oil painting, priming makes sense in most cases. It improves paintability and ensures good, long-lasting results. If you want to experiment creatively, you can also use unprimed canvases – depending on your technique and the effect you want.
