TECHNIQUE 37

Shaped Edge Washes

Combine chaos with control using wash pours for wild color blending effects and a method to maintain hard edged shapes. See Technique 38 for another way to combine hard and soft edges with pouring.


Materials List

Paint

One or more acrylic paint colors (or acrylic inks, high flow or airbrush colors)

Substrate

Any primed painting surface

Tools

Paintbrush or eyedroppers, mixing palette or containers

Products

Acrylic gesso

For Cleanup

Water, water container, paper towels or rags


STEP 1 Prepare the Surface

A satin or semi-absorbent surface works the best for this technique obtained with one coat of a good quality gesso, or using a pre-primed surface. If your surface is glossy, apply a thin coat of matte medium or acrylic gesso. Let dry.

Dip a brush in water, then apply onto the surface thinly in areas and shapes wherever you will want color. Here a letter is being painted onto the surface with water. Immediately proceed to the next step while wet.

STEP 2 Add Color

Select a few paint colors and dilute with water in a 1:1 ratio for fluid paints, more water for heavy bodied, and no water for inks or other thin acrylics. Dip a brush into the colored washes or suction into an eyedropper and apply color in one or more places in the wet areas on the surface. The color immediately moves outward on its own, filling in the wet shape. If the watered shape on the surface dries before you get the chance to add color, reapply water. Best results are obtained by letting the paint and water do its own thing without overworking. Let dry.

Finished Example

Coated pours create the background while shaped edge washes create the horse.
