Acrylic paints have revolutionized the art world with their versatility and vibrant colors. But unlike their oil-based counterparts, acrylics dry incredibly fast. This rapid drying time presents a unique challenge for artists: how do you keep your brushes from hardening into unusable plastic clumps mid-painting? The answer lies in a simple yet crucial practice: keeping your brushes submerged in water.
This seemingly mundane act is the cornerstone of acrylic painting, ensuring your brushes stay supple, your colors remain pure, and your creative flow remains uninterrupted. In this comprehensive guide, we’ll delve into the science behind this practice, explore its impact on your artistic process, and provide expert tips for optimal brush care.
The Science of Acrylics and Water
To understand why water is essential for acrylic painting, we need to grasp the fundamental nature of acrylic paints. These paints are composed of pigment suspended in a polymer emulsion. When wet, this emulsion allows the pigment to flow freely, giving acrylics their characteristic smooth application. However, as the water within the paint evaporates, the polymer particles bind together, forming a durable, water-resistant film. This process, known as polymerization, is what causes acrylics to dry so quickly.
Now, imagine what happens when this drying process occurs on your brush. The acrylic paint binds the bristles together, transforming your once-flexible tool into a rigid, unusable mass. By keeping your brush submerged in water, you prevent the paint from drying and hardening on the bristles, effectively extending its lifespan and maintaining its performance.
The Benefits of Keeping Brushes Wet
Beyond preventing your brushes from turning into plastic sculptures, this practice offers a multitude of benefits that significantly enhance your painting experience:
- Maintains Brush Shape and Flexibility: Water prevents the acrylic polymer from solidifying on the bristles, preserving their natural shape and spring. This ensures smooth, consistent strokes and prevents the paint from applying unevenly.
- Prevents Color Contamination: When switching between colors, dipping your brush in water rinses away residual pigment, preventing unwanted color mixing and muddy hues. This is crucial for maintaining color purity and achieving vibrant, accurate results.
- Extends Brush Lifespan: By preventing paint from drying and hardening, you significantly reduce wear and tear on your brushes. This translates to longer-lasting tools and cost savings in the long run.
- Enhances Creative Flow: The constant need to clean and dry brushes can disrupt your creative momentum. Keeping your brushes submerged allows for seamless transitions between colors and techniques, fostering a more fluid and intuitive painting process.
Best Practices for Brush Care
While the concept is simple, there are nuances to effectively keeping your brushes hydrated during your painting sessions:
- Use Two Water Containers: One container for rinsing excess paint and another for keeping your brushes submerged when not in use. This prevents dirty water from contaminating your colors and ensures your brushes stay clean.
- Submerge Only the Bristles: Avoid immersing the ferrule (the metal part that holds the bristles) in water for extended periods, as this can weaken the adhesive and cause the bristles to loosen.
- Change the Water Regularly: As you rinse your brushes, the water will become saturated with pigment. Replace the water frequently to prevent the buildup of paint particles, which can redeposit on your brushes and affect your colors.
- Use a Brush Holder: A brush holder that suspends your brushes over the waterline is ideal. This prevents the bristles from bending or getting damaged while ensuring they remain submerged.
- Clean Thoroughly After Use: At the end of your painting session, thoroughly clean your brushes with soap and water to remove all traces of paint. This prevents the acrylic polymer from drying and damaging the bristles.

Frequently Asked Questions
Q: Can I use any type of water for my brushes?
A: While tap water is generally fine, distilled water is preferable as it’s free of minerals that can potentially affect the paint.
Q: How often should I change the water in my brush container?
A: It depends on how frequently you rinse your brushes and how much paint you’re using. A good rule of thumb is to change the water whenever it becomes cloudy or filled with pigment.
Q: What happens if I forget to put my brush in water and the paint dries?
A: Don’t panic! You can try soaking the brush in warm soapy water or a specialized brush cleaner to soften the dried paint. However, repeated instances of dried paint can damage the bristles, so it’s best to avoid this whenever possible.
Q: Can I leave my brushes in water overnight?
A: It’s generally not recommended to leave brushes submerged in water for extended periods, especially natural hair brushes. Prolonged exposure to water can weaken the glue holding the bristles and cause them to fall out.
Q: How do I store my brushes after cleaning them?
A: After cleaning and drying your brushes, store them upright in a jar or container to maintain their shape and prevent the bristles from getting damaged.

Beyond Brush Care: Mastering Acrylic Techniques
Keeping your brushes hydrated is just one aspect of successful acrylic painting. To truly harness the power of this medium, consider exploring various techniques that can elevate your artistic expression:
- Layering: Acrylics dry quickly, allowing you to build up layers of color and create depth and dimension in your artwork. Experiment with transparent and opaque layers to achieve different effects.
- Blending: While acrylics dry fast, you can achieve smooth blends by working quickly and using a wet-on-wet technique. Alternatively, you can use blending mediums to extend the drying time and create gradual color transitions.
- Dry Brushing: This technique involves using a brush with very little paint to create textured effects. It’s ideal for adding highlights, creating texture, and suggesting details.
- Impasto: Apply thick layers of paint to create a textured, three-dimensional effect. This technique is often used to add emphasis and create a sense of movement in a painting.
- Glazing: Thin down your acrylics with a glazing medium to create translucent washes of color. This technique adds depth and luminosity to your artwork.
By mastering these techniques and incorporating proper brush care practices, you can unlock the full potential of acrylic paints and bring your artistic vision to life.
Conclusion
The simple act of keeping your brushes in water while painting with acrylics is a fundamental practice that can significantly impact your artistic journey. It preserves your brushes, enhances your painting experience, and ultimately contributes to creating beautiful, long-lasting artwork. So, the next time you pick up your acrylics, remember the importance of this simple yet essential step. Happy painting!
