A flat wash is a foundational watercolor technique used to cover a section of paper with a smooth, uniform layer of a single color without streaks or variations in tone. It's ideal for creating even backgrounds, skies, or base layers.
Mastering the Flat Wash Technique
Achieving a consistent flat wash relies on a few key principles and techniques.
The Zigzag Motion and the Bead
According to the provided reference, one method for painting a flat wash involves applying the paint in a "zigzag motion." This means moving your brush horizontally back and forth across the area you are painting, working your way downwards.
A crucial element in this process, also highlighted in the reference, is the formation of a "bead." The reference states, "wherever you lift your brush, up a small puddle forms. This is called a bead." These beads are essentially the wet edge of your wash. It's important to note that, as the reference mentions, "beads take longer to dry." To create a successful flat wash, you must ensure that each new stroke connects and merges smoothly into the bead formed by the previous stroke. This keeps the entire area you are working on consistently wet, allowing the paint to dry evenly without leaving hard lines or 'tide marks'.
Steps for Applying a Smooth Flat Wash
Follow these steps to paint a uniform flat wash:
-
Preparation is Key:
- Mix Enough Paint: Prepare a generous amount of paint mixture in your palette. Running out of paint mid-wash is a common mistake that can ruin uniformity.
- Load Your Brush: Use a large, soft brush (like a flat or round wash brush) that holds a lot of liquid. Load it fully with your prepared paint mixture.
- Tilt Your Paper: Angle your paper slightly (e.g., 15-30 degrees) using a board or books. Gravity will help the paint flow downwards and maintain the bead.
-
Painting the Wash:
- Start at the Top: Begin your first stroke at the top edge of the area you want to cover.
- Use the Zigzag: Paint a horizontal stroke across the paper. At the end of the stroke, turn the brush around and paint another horizontal stroke immediately below the first, slightly overlapping it. Continue this zigzag motion, working downwards steadily.
- Maintain the Bead: Ensure a consistent bead of paint forms along the bottom edge of your current working area. Your next stroke must connect and merge smoothly into this bead. This is vital for an even wash.
-
Finishing:
- Work Quickly: Try to complete the entire wash area in one continuous flow before sections start to dry.
- Address the Final Bead: Once you reach the bottom of your desired area, a larger bead may accumulate. You can gently lift this excess using a clean, thirsty (relatively dry) brush by touching the tip into the bead.
Essential Elements for a Flat Wash
| Element | Purpose | How to Achieve It |
|---|---|---|
| Zigzag Motion | Efficiently covers area while creating a consistent wet edge | Horizontal strokes back and forth, moving downwards |
| Bead (Puddle) | Maintains a wet boundary for even drying | Ensure enough paint and proper paper tilt |
| Sufficient Paint | Prevents patches and ensures consistent color density | Mix more paint than you think you'll need |
| Consistent Speed | Avoids areas drying faster than others | Work methodically and continuously |
By focusing on the zigzag motion and diligently managing the bead, as highlighted in the provided reference, you can effectively paint a smooth, even flat wash.
