A liner is a round brush with hair far longer than its diameter. The extra length is a reservoir: the paint sits along the shaft and feeds the point continuously, so the line stays the same width from start to finish instead of fading after two centimetres.

What to pair it with
It needs thinner paint than a normal round brush – too thick and the reservoir will not flow. For lines that change width, AK Synthetic Brush – Dagger L is the better shape.
Frequently asked questions
The long hair feels unstable – am I holding it wrong?
A liner is controlled from the very end of the handle with a light touch. Gripping it close to the ferrule like a detail brush makes it wobble.
What consistency does it need?
Roughly like milk. Too thick and the paint never reaches the tip; too thin and the line breaks up.
How do I clean an AK synthetic brush?
Rinse it in clean water – or the matching thinner for enamels and oils – before the paint sets, work brush soap into the bristles with your fingers, reshape the tip and let it dry point-up. Never leave a brush standing in a jar. The cleaners are in thinners and cleaners.
Synthetic or Kolinsky sable?
Synthetic fibre is springier, cheaper and completely indifferent to harsh thinners, so it is the right choice for varnish, enamels, oils, pigments and every abrasive technique. Sable holds more liquid and comes to a finer point – that is the da Vinci brushes range. Most painters end up owning both and using each for what it does best.
The complete range is in the AK Interactive brushes category.
