Acrylic Gesso and Why You Need to Use It

 
Acrylic Gesso is Primer that is used on canvas or any other painting support. Hereby Gesso is used to prepare ("prime") the surface for painting. It dries hard, making your painting support stiffer, slightly textured and ready to accept Acrylic Paint. Without gesso, the paint would soak into the weave of the canvas.

What is Acrylic Gesso made from? Modern acrylic gesso is a combination of calcium carbonate (chalk) with an acrylic polymer medium (binder), a pigment (titanium white) and other chemicals that ensure flexibility, and ensure long archival life. Back in a days artist used to make their own Gesso. And guess what they used as a glue part of it? Rabbit skin! Fortunately, there is no need for that anymore! You can buy great quality gesso from multiple art suppliers and thanks to modern formula, no animals got hurt.
 

Different types of Acrylic Gesso


Grade

Acrylic Gesso Smart Art MaterialsJust like with paint, there are two different grades of gesso: Artist grade and Student grade. The difference between the two amounts to the different ratios of pigment and filler. As with paints, the differences are reflected in the quality, and also in the price.

Artist grade has more pigment, higher opacity and is normally thicker than Student grade. Great for the creation of a smooth surface. If you are painting onto a raw canvas the artist grade is also essential due to the increased opacity.

Student grade contains the lower quantity of pigment and more filler than the Artist grade. Student grade is usually available only in white. This one is good for adding a bit more absorbency to a pre-primed canvas.

Consistency

This one has the ability to hold sculptural shape, providing all the attributes of regular gesso. Also, Gesso is available as a Spray.  You shake the can and spray the gesso directly onto your canvas, with no need for a brush. Besides, the consistency and texture of gesso vary from brand to brand.

Colors

Acrylic Gesso is traditionally White, but you can buy premixed Black, Colored, and Clear Gesso. This can be really handy if you like to paint on the dark background. You can also tint your gesso to make it almost any color you want: just mix in a little bit of acrylic paint!




What about pre-primed canvases?


canvassmart1“Pre-primed” means “pre-gesso”, so it already has a gesso layer applied in the factory. You can buy pre-stretched and pre-primed canvas (this will be indicated on the packaging), so you can start painting them with acrylics without any extra steps. By the way, most of the pre-stretched canvases are pre-primed.

Do you need to gesso it? This step is unnecessary, however, sometimes you may feel that the canvas lacks tooth and absorbency, especially if it a cheaper canvas. Therefore give the canvas another coat or two of gesso, and enjoy the difference!

Brand


There are too many different brand available out there. I've tried a lot - student and artist grade - and came up with the winner.  Gold goes to Liquitex Professional Gesso! Great quality for reasonable price.

There are few different types of Liquitex Gesso available: White, Heavy White, Clear, and Colored. Check out more information here.

Gesso Primer In fine...


Gesso can be used on multiple surfaces, such as canvas, paper, wood, glass, and fabric. Well, pretty much on anything that is used for painting. 

Overall, Acrylic Gesso is a great tool, and it is popular among artists for a reason. Still, using gesso and pre-primed surfaces, or paint on raw canvas is totally up to you. It all depends on how you want your artwork to look. I prefer primed support, but recommend you to try both just to see the difference in the painting process and the final look. Certain styles of contemporary art might actually benefit from painting directly onto a raw canvas.

    This is a great asset for up and coming artists being able to buy quality primers for their canvas. The acrylic-gesso looks to be a quality product made from non animal products, i was never aware that animals,especially rabbits were used originally.I have done some painting in the past but i never got to your standard.

    Very helpful!
    Without this post I wouldn’t have known all the differences there are to be found.
    As Andrew said, I never thought animal cruelty went also on the production of gesso!
    And most importantly I wouldn’t have known what would be the best quality products!
    On top of that, an animal-friendly one too!
    Thank yu very much for your review and informational post about gesso!
