Discover the Essential Types of Watercolor Brushes: Pros, Cons, and Care Tips

When I first started painting with watercolors, I was overwhelmed by the number of brush options available. With so many brands and types, I didn’t know where to begin. Over time, I discovered which brushes are truly essential and how to take proper care of them. Today, I’m sharing a simple guide to help you understand the most common types of watercolor brushes and how to choose the right ones for your painting needs.

Types of Watercolor Brushes

1. Round Brush
The round brush is one of the most versatile tools for watercolor painting. Available in various sizes, it’s helpful to have a small, medium, and large round brush with a fine tip. This brush is perfect for precise details, thin lines, and washes of color.

2. Rigger Brush
Also called a liner brush, the rigger is ideal for painting long, fine lines—great for tree branches or intricate floral details.

3. Designer Brush
Similar to round brushes but designed for extreme precision, designer brushes are perfect for detailed illustrations and delicate work.

4. Cat’s Tongue (Filbert)
The cat’s tongue brush has a rounded tip that offers more flexibility in strokes. It’s excellent for blending and applying soft washes.

5. Flat Brush / Wash Brush
Flat brushes are best for covering large areas, creating broad strokes, and applying background washes.

6. Fan Brush
Used for special effects, the fan brush is perfect for creating textures, foliage, and grassy landscapes.

7. Mop Brush
Ideal for soft gradients and large washes, the mop brush holds a lot of water and is especially useful for painting skies or large backgrounds.

Must-Have Brushes

Although there are many types of brushes, the ones you’ll use most often are round and flat brushes. A basic set of three round brushes (small, medium, and large) with fine tips is essential. My favorite brands are Princeton and Silver Velvet, known for their excellent quality and durability. 

I also recommend having a ¾ wash brush for wetting the paper—especially useful for landscapes, skies, and backgrounds where you want an even flow of color.

Another favorite tool in my kit is a chisel blender brush, size 6, recommended by my talented artist friend Manuela (you can check out her work at Alma Colors). This brush is ideal for:

  • Blending hard edges or softening mistakes
  • Creating clean borders or artistic frames

Lastly, a liner brush (size 0 or 1) or a rigger is great for painting fine lines, like branches, stems, or delicate details.

Having these essential brushes on hand will make your watercolor journey smoother and more enjoyable!

Natural vs. Synthetic Hair

Natural Hair Brushes
Pros:

  • Hold more water, perfect for wet techniques and large washes.
  • Offer a more responsive and fluid painting experience.

Cons:

  • More expensive.
  • Require extra care.
  • Made from animal hair (e.g., sable, pony, or squirrel).

Synthetic Brushes
Pros:

  • More affordable.
  • Durable and easier to clean.
  • Great for precise work and ethical (no animal hair).

Cons:

  • Don’t hold as much water as natural brushes.
  • May not provide the same softness or flow—especially noticeable when painting landscapes.

Brush Care Tips

Taking care of your brushes will extend their life and keep your painting experience enjoyable. Here are a few tips:

  • Don’t leave brushes in water. This can deform the bristles and ruin the tip.
  • Clean brushes immediately after use. Use lukewarm water and mild soap if needed.
  • Dry flat. Lay them on a towel or paper to dry horizontally, keeping the tip’s shape intact.
  • Store properly. Use a brush case or holder that protects the bristles and keeps them straight.

I hope this guide helps you feel more confident when choosing and caring for your watercolor brushes. Remember, the right tools—combined with regular practice—will take your watercolor skills to the next level.

Happy painting! 🎨
