Derwent Push-Button Waterbrush - Medium Nylon Tip, Leak-Resistant Barrel for Controlled Flow

The Derwent Push Button Waterbrush Medium Tip is a portable water reservoir brush with a spring-loaded button that delivers precise, controllable water flow for layering and texture-building with watersoluble media.

This medium-tip waterbrush combines a sizeable transparent barrel with a push-button mechanism so you can meter water to your work without needing a jar. It’s designed for use with watersoluble paints and pencils, and its durable nylon fibre tip keeps a reliable point through repeated use. Lightweight, leak-resistant and capped for transport, it’s as useful at a desk as it is on location.

How does the push-button water release improve control?

The spring-loaded push button lets you release small, consistent amounts of water on demand, preventing sudden floods and oversaturation. That control helps you build washes, blend pigments, and layer colour more predictably than squeeze-barrel brushes.

• Button delivers metered water drops for fine gradations
• Large barrel reduces the need for frequent refills
• Transparent body lets you see remaining water and flow rate

What effects can I achieve with the medium nylon fibre tip?

The medium nylon tip balances a defined point with enough belly to hold water, making it suitable for both detail work and broader strokes. It maintains shape over time so your edges stay crisp while still allowing soft blends when you need them.

• Holds a steady point for line work and textures
• Spreads water for smooth gradients and layering
• Durable fibres resist fraying for consistent performance

Is this brush suitable for travel and outdoor painting?

Yes—its leak-proof design and protective cap make it ideal for sketching outside or packing in a bag. The refillable barrel and one-handed push operation mean you can work quickly without hunting for a water source.

• Secure cap prevents spills in transport
• One-handed button action simplifies on-site adjustments
• Lightweight construction reduces carry weight for plein air sessions

How does it perform with watercolour pencils and other watersoluble media?

The water flow and medium tip pair well with watersoluble pencils and pan paints, activating pigment without washing it away completely. You can lift, blend, or push pigment into texture, making it versatile for mixed techniques.

• Activates pencil pigment smoothly for washes and lines
• Allows layering without immediate over-dilution of colour
• White tip helps monitor pigment concentration during use

Who is this for: Artists who want a reliable, easy-to-control waterbrush for sketching, mixed-media, or layering with watersoluble paints and pencils. It fits sketchbook users, urban sketchers, students, and hobbyists who value portability and predictable water delivery. If you prefer a brush that keeps its point, minimizes spills, and makes on-the-go painting faster, this medium-tip Derwent waterbrush is purpose-built for those habits.
