FAQs

Do I need a medium if water mixable oil paints work with water?
No, but using a medium significantly improves how the paint performs. Water can thin the paint, but a medium helps maintain the smooth, rich consistency of oil paint while improving flow, blending and overall finish.

What’s the difference between using water and a medium?
Water dilutes the paint and can reduce colour strength, while a medium enhances the paint, keeping colours vibrant, improving control and allowing techniques like glazing and layering.

Can I clean my brushes with just water?
You can rinse brushes with water, but it won’t remove all the oil and pigment. Over time, residue can build up and affect brush performance.

Why should I use a brush cleaner instead of water?
A proper brush cleaner removes leftover paint more effectively, helps keep bristles soft and extends the life of your brushes, especially with regular use.

Are these products safer than traditional oil painting materials?
Yes. Water mixable oil mediums and cleaners are designed to be low-odour and used without harsh solvents, making them ideal for home studios, classrooms and shared spaces.

Who should use mediums and brush cleaners?
Any student or professional artist who wants better results from their water mixable oil paints, especially when working on detailed pieces, layering techniques or long painting sessions.
