Water brushes have changed when and where artists can paint. Whether it's hiking the Appalachian trail or piloting the Millennium Falcon, water brushes open a universe of possibilities for painting on the go.
A water brush is a reservoir of water attached to a brush. Water flow is controlled by a small plastic feed and can be increased by squeezing the barrel. Artists love their portability: water brushes can be filled from any source, remove the need for open water containers, and clean themselves through use.
Water brushes all function similarly, with slight differences between brands and sizes. The few differences they have make them great to use as a set. While they all performed admirably, we found these to be our favorites.
Water brushes are the perfect accompaniment for small watercolor sets. These small pans of dry paint can easily be activated for painting with a few strokes of a water brush.
- Use the water brush to pull color from dry or wet watercolor pans. You can squeeze the water brush to add water to the paint pans if desired.
- Paint directly on to the paper. When the color begins to fade, return the brush to the pan to dissolve more color onto the brush.
- You can mix colors in a separate tray, or with thin washes of colors on the paper.
- Clean your brush between colors by wiping your brush on a paper towel or other absorbent surface until the brush flows clear again.
- A clean water brush can be used to soften edges, blend colors, or scrub away unwanted color.
Watercolor markers are water-soluble dyes contained in a convenient marker body. Their vivid colors are easily dissolved with a water brush.
- The easiest way to use a water brush with watercolor markers is to apply the markers first, then dissolve the color with the water brush. This provides the most intense color and is great for deep shadows.
- For softer colors, pull color from the marker tip with the water brush. Once you have absorbed the desired amount of color, paint with the brush on the paper.
- Soft-focus and blurry effects can be created by painting with clear water first, then drawing in the wet area with the marker.
A water brush can easily be transported with a set of watercolor pencils for fast color and fast clean-up.
- Before applying water, you can color with the pencils on the paper.
- Activate the color with the water brush. To prevent color contamination, paint small areas of similar color, then let dry.
- Light pressure will give fainter color which dissolves more completely with the water brush. Heavy pressure will create more intense color but may leave a pencil texture. Coloring with two or more colors will create a single color when wet.
- You can also dissolve color straight from the tip of the pencil to paint fine details.
Gel inks are partially water-soluble, and release a small amount of color when painted over with water. A water brush can add shading to a drawing without compromising the pen lines.
- Use the water brush to dissolve some color from a pen drawing.
- Denser lines will produce a darker wash, while sparse lines will only release a little color. Some inks will separate into different colors.
- This technique works with Pilot Hi-Tec-C pens and Pentel Slicci pens. Uni-ball Signo pens are specially formulated to be waterproof and will not work.

Many fountain pen inks can be dissolved with water. Adding a few splashes with a water brush can add a feeling of spontaneity to a drawing.
- Use a water brush over a fountain pen drawing to dissolve the ink.
- Some color will remain on the water brush and can be used for light color elsewhere.
- Some inks will not dissolve with a water brush, while others will dissolve partially or completely.

Most mediums contain large particles or are too thick to use in a water brush. Some of the materials we tested destroyed our water brushes completely. We do not recommend filling a water brush with acrylic inks, such as the Speedball Calligraphy ink, white inks, or metallic and other dip pen inks.
|Ink Type||Compatible with a Water Brush|
|Fountain Pen Inks||Yes|
|White and Opaque Inks||No|
|Dip Pen Inks||No|
