Watercolour Brush Rembrandt Series 100 No. 6 – round brush for watercolour painting, natural/synthetic blend

Rembrandt Watercolour Brush Series 100 No. 6 is a round brush intended for watercolor painting, gouache and mixed media. The brush combines natural and synthetic fibers to offer a balance of paint loading, spring and tip retention. Size No. 6 provides a mid-range option for controlled washes, medium lines and detail work, making it suitable for classroom use, studio practice and hobby projects.

Advantages

The blended natural/synthetic construction delivers good paint absorption and a resilient spring that helps the brush hold its shape during repeated strokes. The fine-pointed round tip enables precise lines and controlled edges, while the belly stores sufficient water and pigment for longer, uninterrupted strokes. The handle length and ferrule construction are optimized for balance and comfortable control during extended painting sessions.

Suitable for

• Watercolor painting at student and professional levels

• Fine details, medium lines and controlled washes
• Study exercises, plein air sketches and illustrative work

How to use

Wet the brush and load it with the desired amount of paint or wash; test strokes on scrap paper to adjust paint-to-water ratio. Use the tip for fine lines and controlled details, and use the belly of the brush for broader, continuous strokes and smooth washes. Rinse and reshape the tip between color changes to maintain a clean point. After each painting session, clean gently with mild soap and lukewarm water, reshape the tip and allow the brush to dry horizontally or with the bristles pointing downward.

Usage recommendations

For best results with watercolor techniques, pair the brush with medium-weight cold-pressed paper and high-quality transparent pigments. Avoid prolonged soaking of the ferrule and store the brush upright or flat to preserve the shape of the bristles.
