How to use it

Four steps with a filbert brush.

A filbert combines the qualities of a flat and a round brush. The result depends on which part of the bristles touches the canvas.

1
Choose a size
Choose nos. 0–4 for details, nos. 6–10 for shapes and leaves, and nos. 12–16 for areas and backgrounds.
2
Load the paint
Load paint across the full width of the bristles. With acrylics, you can dampen the bristles before painting to help the paint glide more easily.
3
Paint with the flat side and the edge
Use the flat side for a broader stroke and the edge for a fine line. Press the rounded tip lightly to create a petal.
4
Clean straight away
Wash acrylic paint out with water before it dries; clean oil paint with a suitable solvent, then soap. Dry the brush horizontally or with the bristles pointing downwards.

Phoenix 6604E Filbert Paintbrush for Acrylics and Oils

A filbert is a flat brush with bristles rounded into an oval at the tip. It has a flat ferrule and medium-to-long bristles with soft, rounded edges, making it suitable for blending colours and figurative painting. Phoenix makes it in the 6604 series with synthetic coloured nylon bristles and a long burgundy handle.

What is a filbert brush used for?

For acrylics and oils, it is suitable for painting petals, leaves, clouds, soft facial contours and smooth transitions between two shades. Unlike a flat brush, it leaves no sharp corners, making it easier to blend strokes together.

Details: nos. 0, 2, 4
Shapes and leaves: nos. 6, 8, 10
Areas and backgrounds: nos. 12, 14, 16

How to care for your brush

Wash acrylic paint out with water before it dries; clean oil paint first with solvent, then soap. Reshape the bristles and don’t leave the brush standing bristles-down in a jar.

FAQ

Frequently asked questions.

Quick answers to common questions about choosing a paintbrush.

What is a filbert paintbrush?

A flat brush with bristles rounded into an oval at the tip, known as a filbert. It is suitable for blending colours and figurative painting because its rounded edges leave no sharp edges.

What are the bristles made of?

Synthetic coloured nylon bristles, as used throughout the 6604 series. The bristles are two-tone, with a light colour and a darker tip.

Is it suitable for both oil and acrylic paints?

Yes, the filbert shape is designed for oils and acrylics. Clean the brush with solvent and soap after using oils, or with water after using acrylics.

Which size should I choose to get started?

A medium size, No. 8 or 10, is a versatile choice. Add No. 2 or 4 for details, or No. 14 or 16 for backgrounds.

Why does the brush have a long handle?

The long handle is useful when working at an easel: you can paint further from the canvas and see the whole painting more easily.
