4 Questions About Acrylic Portrait Painting, Answered

Sanding a canvas panel in preparation for painting an acrylic portrait

On the last couple of layers, I mix the gesso with matte medium to make it go on smoother. If I am using a store bought canvas covered panel, I will add 1 or 2 layers of gesso and matte medium to smooth out the grooves in the canvas, sanding in between. This allows me to get a smooth surface for portrait painting.

I use the glazing technique to slowly bring the portrait from a white canvas to completion. The glazing technique is achieved by mixing your paint with clear acrylic medium (usually matte medium) to disperse the pigment, thus allowing light to pass through.

Although you could use water, it’s not recommended, because it breaks down the acrylic resin binder, causing a rough visual texture and possible poor adhesion. For a smoother look, you want to use clear acrylic medium.

Why do I paint with layers with the glazing technique?

Here’s why: by creating semi-transparent or translucent layers, the light passes through them, reflecting off the white primer beneath, and then back to your eye. It gives the painting a radiance, a glow. It also causes the deeper colors to be more saturated, more vivid.

Finally, it allows me to create smooth gradients. We all know that acrylic, because it dries so quickly, is difficult to blend. The glazing technique overcomes that limitation by using the strategic placement of layers and dilution of pigment with medium to create the transition from one value or color to another, rather than by relying on blending only while the paint is wet.

3. You mentioned using a Prismacolor pencil for making your diagram.  What color do you recommend?

I recommend using burnt ochre or sienna brown for most portraits because it matches easily with the skin tone. For people with a very pink skin tone, terra cotta could also be used. Those with a dark complexion might require using dark brown. If you prepare the canvas as I demonstrate in my teaching videos, you will find colored pencil very easy to erase, and it doesn’t smear much either. That, coupled with being able to match the skin tones right away, makes it the perfect pencil to sketch with.

Using colored pencil for your acrylic portrait sketch makes things a lot easier. Technique discovered and developed by Matt Philleo.
