Before choosing: the 4 qualities of a good watercolor brush

Even before talking about brand or price, a good watercolor brush is recognized by a few criteria.

A sharp point (even with a large brush)

🖌️ Contrary to popular belief, a larger brush is not less precise.
A good medium-sized round brush (8–10) maintains a fine point once wet.

Result: you create washes without streaks, then details without changing brushes.

If the tip flattens or spreads too quickly, control becomes difficult.

A water "reservoir" (the belly of the brush)

💧 The "belly" of the brush is its ability to retain water and color.
The better the reservoir, the more fluid the stroke.

Why it makes a difference:

• fewer trips back and forth to the water or palette,
• more regular washes,
• fewer rework marks on the watercolor paper.

Snap (spring) vs. softness (flexibility)

🎯 Each painter has a different feel.

• If you feel like you're trembling or can't control your stroke → the brush might be too soft.
• If you bleed easily or the brush "goes by itself" → it might lack snap.
• If you can't control the water flow → the reservoir or the fiber might not suit you yet.

Synthetic brushes are often snappier. Natural bristles are softer and more fluid.

The ferrule + the handle

🔍 These details are often overlooked... yet essential.

To check: the ferrule (metal part) must be tight, without play, no bristles should escape at the base, the handle must be smooth, without cracks, well balanced in the hand.

The main types of watercolor brushes

When talking about watercolor brushes, a few shapes always come up.
You don't need to know all of them to get started. Here's the essential, with what they're really for.

The round (pointed) brush: the true essential

🖌️ This is the brush to recommend.
If you only had to choose one, this would be it.

It is well suited for beginners because it allows for washes, to draw fine lines and to add details, thanks to its point.

A good medium-sized round brush can cover 80% of watercolor uses.
It is the most versatile, the most reassuring... and the most used.

The flat brush: washes, lines, architecture

📐 The flat brush is very useful in specific cases.

It is mainly used for:

• painting large and even backgrounds,
• drawing clean bands,
• working on geometric or architectural shapes.

It becomes interesting when you like structured compositions or well-defined backgrounds.

The wash brush / "mop" / "quill": large washes, skies, backgrounds

💧 This brush is recognizable by its round and very full shape.
It is designed to hold a lot of water.

Typical case:

• you love skies, blurry backgrounds,
• you like very wet gradients,
• you often paint in large format.

These brushes often come in squirrel hair or imitation squirrel hair, known for their enormous water retention. They offer a very fluid stroke, ideal for generous washes.

The "bonus" brushes: fan, cat's tongue, liner

🌿 These brushes are interesting... but not essential at the beginning.

They are used for specific purposes:

• fan: grasses, foliage, textures,
• cat's tongue: soft shapes, petals,
• liner: long and thin lines.

Save them for later, when you want to explore specific effects.

Natural vs. synthetic bristles: which one to choose without making a mistake?

This is one of the questions when looking for which watercolor brush.

Kolinsky Sable: precision, snap, and longevity

🖌️ Kolinsky sable brushes are often considered the top-of-the-line for watercolor.

They are known for: an extremely precise point, excellent snap (the brush returns well to its place), a long lifespan if well maintained, good water retention, without excess.

It's a real painting pleasure... but also an investment.
They are especially interesting if you paint regularly and already know what you like.

👉 Models like Raphael 8404 or Winsor & Newton Series 7 are often cited together in user discussions as quality references.

Squirrel (petit-gris): softness and huge reservoir

💧 The squirrel brush is the opposite of sable.

Its strengths:

• extreme flexibility,
• an impressive water reservoir,
• very fluid and natural washes.

It's perfect for: skies, backgrounds, very wet gradients, broad strokes.

However, it is less precise for details.
It is a brush for feeling and movement, rather than control.

Modern synthetics: the best "no regrets" start

💡 Modern synthetic brushes have progressed enormously.
They are often the best choice for beginners.

Two families often come up in discussions:

• imitation squirrel (e.g. Neptune type): very soft, ideal for washes,
• imitation sable (e.g. Aqua Elite type): firmer, better precision.

These differences explain why two synthetic brushes can give very different sensations.

What brush size to choose?

If you hesitate between several sizes, rest assured: it's normal.

The simple rule: "bigger than you imagine"

🖌️ Many beginners choose a brush that is too small.
The result: the paint dries too quickly, leaves marks, and you go over it again... which creates even more marks.

A slightly larger brush: holds more water, makes strokes more fluid, facilitates gradients, and avoids frustration from the first session.

The easy duo (recommended)

🎯 If you want to keep it simple, here's the duo that works almost every time:

• 1 medium pointed round brush (often 8–10): washes, glazes, shapes, almost everything
• 1 small round brush (often 2–4): details, outlines, small touches

With these two, you cover most needs, without getting scattered.

Popular models and brands

Two brushes from the same range can give very different feelings depending on the shape, fiber, and your stroke. The goal here is to give you reliable benchmarks.

Entry-level that gets the job done (beginners)

🎯 For whom? Beginners, parents, teachers, occasional practice.

Recommended sizes to start

• Round pointed 8–10 (versatile)
• Small round 2–4 (details)

Much-loved mid-range

🌿 For whom? Motivated beginners, regular amateurs.

The Princeton Neptune range is often appreciated for:

• its flexibility (synthetic squirrel imitation),
• its good water retention,
• its comfort for washes and backgrounds.

Note: feedback varies depending on the point and size.
Some prefer these brushes for washes, others for medium to large formats. To be tested according to your style.

High-end "point + reservoir"

✨ For whom? Regular practice, seeking precision and durability.

Kolinsky sable brushes are often cited for their: very fine point, excellent spring, balanced water retention, longevity.

The Raphaël 8404 regularly comes up in discussions for its point/reservoir balance, often compared to the Winsor & Newton Series 7.
These are beautiful tools, designed to last… if properly maintained.

Maintenance: keeping a good point

A good brush can last for years… provided you adopt a few habits.

The 5 rules to adopt

🖌️ These steps are enough to preserve your watercolor brushes:

1. Rinse with lukewarm water
   Avoid hot water, which damages the fibers and ferrule glue.
2. Use a mild soap
   A special brush soap or Marseille soap works very well.
3. Clean without crushing the tip
   Use gentle movements, in the direction of the bristles, without harsh scrubbing.
4. Reshape the tip with your fingers
   This is a key step to maintain a beautiful shape.
5. Let dry flat
   The brush should dry naturally, without pressure.

Mistakes that kill a brush

🚫 Some very common habits damage brushes:

• leaving the brush to soak in water (bristles bend, ferrule loosens),
• drying it head up while it's still full of water,
• forgetting to wash it after the session,
• crushing the tip against the bottom of the pot,
• storing a wet brush in a closed case.
