Encaustic Technique #8: Gesso

A small holiday gift for you all: a new tutorial. This one is a little different. It’s not about the wax, but what we put under the wax.

I’ve written here before about using paper or claybord as a base for painting. About a year or so ago, R&F came out with an encaustic gesso. It doesn’t smell and isn’t labor-intensive like rabbit skin gesso, and, unlike regular acrylic gesso, it is absorbent enough to be used under wax. Until recently, I’ve just used it as it comes: bright white.

Recently, though, I started experimenting with tinting it with powdered pigment before applying it. My aim was to create an aged looking, darker background for painting.

In the above example, I started off with a layer of white gesso. I let that dry completely. Then, I mixed a portion of gesso with my powdered pigment and applied it in large, sweeping strokes to most of the canvas.

After letting this dry slightly, I sprayed the panel randomly with water and scumbled the surface with rags, creating a textured looking surface. When the gesso was completely dry, I sanded portions of it where I wanted more light to come through.

The point here is how flexible this could be- try using different colors, layering colors, or painting into the dry gesso with water based paints, such as guache. The surface could also be stamped with homemade stamps before applying your first coat of wax.

My one critique of the gesso is that it pinholes like crazy (similar to claybord). I remedied this with a lot of fusing and additional layers of wax. I’m not sure what causes the pinholes- If any of you know why it does this, please leave a comment! I’d love to know how to control it.
