AK Interactive Synthetic Brush Condition Fluid (AKB150)

Synthetic bristles lose their spring the same way natural hair does — this fluid puts it back, reshaping the tip and cleaning out the last traces of paint after your usual wash.

How to use

• Clean the brush with water or your usual brush soap first
• Work a small amount of fluid through the damp bristles
• Reshape the tip by hand and leave to dry

It's a one-minute habit rather than a chore, and it's the difference between a brush that lasts a season and one that lasts a couple of years.

Conditioning fluid, sold as a single bottle. Use it alongside any of AK's synthetic shapes — see the full brush range to keep every one of them in good order.
