Gesso What it is and how to use it

©2005 - 2007 by aisling d'art

Gesso is a useful option for art journaling as well as and mixed media art. I use gesso often, because I often create heavily embellished pages in my journals. I need the extra strength that gesso adds to my art journal pages.

However, many (perhaps most) artists never use gesso in their journals.

That said... here's what gesso is and how you can use it.

WHAT IS GESSO?

Gesso is a primer. Artists sometimes apply it to a surface before painting on it. In fact, gesso looks a lot like .

Originally, gesso only came in white. Artists put it on canvas, wood, or other surfaces before creating a painting with or acrylics.

Gesso makes the surface a little stiffer. It prevents paint from soaking into the support (canvas, paper, wood, etc.), and it gives the surface a little more texture (called "tooth"), so the paint sticks better.

Today, gesso comes in many colors. White is still the most popular, but black and colors are also widely used for art journaling and other art.

It's useful for mixed media work as well as fine art . For example, I almost always cover a cigar box with gesso before painting it when I make an art shrine.

WHWHWHATWH AT MAKES GESSO DIFFERENT FROM REGULAR PAINT?

Gesso is different from paint. Generally, it's thinner and creates a slightly rough surface when you apply it.

Originally, gesso was a mixture of calcium--like chalk--in a thin base of animal glue.

When you see religious paintings and icons on wood, they were probably painted over gesso. The gesso kept the paint from sinking into the wood too much, and it made the paint stick better if the wood surface was really smooth. But, gesso changed in the 20th century. In 1955, Liquitex (an company) developed the first water-based acrylic gesso. It provided a consistent and inexpensive primer layer for both acrylic and oil paintings.

In recent years, some artists have begun to question whether or not acrylic gesso is the right product to use under oil paint. While this isn't an issue for most people working in art journals, it's something to think about if you're also working with oils.

GESSO AND ART JOURNALS

As many of us began to create art journals, we found new uses for acrylic gesso. For example, it's ideal for use under collages.

And, the acrylic/oil issue shouldn't affect art journalers who use oil pastels and crayons over acrylic gesso.

When I journal, I use white gesso as well as black gesso.

Here is an example of a page with black gesso on it, and white rubberstamp'd letters. You can see how well gel pens write on black gesso on this other page from my Decluttering Journal .

HOW DO I USE IT?

It's easy to use gesso. However, gesso can get messy if you play with it. I usually spread newspaper on the desk, table, or floor where I'm working, just in case.

Then, shake the gesso container so it's well mixed, open it, and start painting the gesso onto your surface.

I use a cheap sponge brush to apply gesso. Because gesso is water-based, you can use a regular brush if you prefer, and rinse it out afterwards.

If I'm using gesso in an art journal, I apply a thin coat to one side of the page. That's usually enough. However, if I'm planning to apply a heavy collage to the page, I may use gesso on both sides of the page for added strength.

Generally, I apply one coat of gesso, wait for it to dry, and then decide if I need to add another coat.

Cheap gesso has more water in it and will take longer to dry. If you're going to apply gesso to the back of the page, too, be sure to let the paper dry completely before painting that second side. Otherwise, you'll seal in moisture and weaken the paper.

CHEAP OR EXPENSIVE --- DOES IT MATTER?

Everyone will have his or her own opinion on this question.

Personally, when I'm using white gesso--which is most of the time--I buy whatever's cheap. It works fine for my art journaling pages.

I often buy it buy gesso in bulk for additional savings. (It even comes in quart buckets and tubs about the size of ice cream containers.) As long as you put the lid back on securely, and shake or stir the gesso before using it, gesso stores well.

When I want a colored gesso, especially black gesso, I spend considerably more and shop for very good brands.

Also, I've had very good luck tinting small amounts of cheap white gesso for special projects.

I start with a jar or paper cup that's partly filled with white gesso. Then, I slowly add coloring to it, until I achieve the color that I want.

For color, I've had luck with:

• plain (unsweetened) Kool-Aid • Dr. Ph. Martin's concentrated water colors • cheap watercolor paint drizzled into the gesso, and • adding some acrylic to the white gesso.

GETTING FANCY

Many companies are making a variety of gessos for different kinds of art. In addition to a wide range of colored gessos, some companies make a "hard gesso" that goes on thick and can be sanded to a smooth finish. Although this product would be too heavy for use on regular journal pages, it could be useful on a heavy journal cover or other support.

You can also buy gesso powder and other powders that will mix into acrylic (and other) gessos to make them heavier, thicker, textured, and so on. SUMMARY

Gesso is the primer that helps your paint stick to the paper or fabric (or other) surface, and also keeps the paint from soaking into your journal page. Gesso can also add body or strength to the paper, so that you can apply heavier elements such as layers of collage.

You don't have to use gesso, ever. It's just an extra tool for us to use when we're creating art in our journals.
