Use Jo Sonja's Flow Medium to thin Jo Sonja's Artists' Colours and mediums. (Not recommended to be used with Crackle Mediums and varnishes).
Water may dilute paint's acrylic binder, reducing the adhesive qualities. When Flow Medium is added in small amounts, it produces a thinner, smoother paint which leaves no brush marks. Paint mixed with Flow Medium will deliver a remarkably long stroke with very fine detail and definition.

Directions:

• Mix into desired colour using brush or palette knife starting at a ratio of 2 parts paint to 1 part Flow Medium.
• Make sure Flow Medium is evenly dispersed before applying paints. Use this combination for all techniques requiring a smooth finish, such as base coating. Addition of Flow Medium to the paint will delay the drying time.
• Decorate as desired.

Airbrushing 
Use Jo Sonja's Flow Medium instead of water to reduce the viscosity of Jo Sonja Artists Colours. Most airbrush artists use 3 parts Flow Medium to 1 part paint. This will vary with your style and equipment.

Troubleshooting 
Reaction with varnish 
Allow adequate drying time before applying varnish. Flow Medium may take 3-5 days to dry depending on climatic conditions. A hair dryer will speed the process.
