Frequently Asked Questions

AI
Flow mediums reduce surface tension to help paint spread smoothly and level out brushstrokes, ideal for pouring. Glazing mediums extend paint transparency and slow drying time, allowing for layered, luminous effects without altering colour intensity.
While some mediums can be mixed with gesso, they are not direct substitutes for priming surfaces. Mediums are designed to modify paint properties, whereas primers prepare the canvas or board to accept paint and prevent absorption.
For acrylic pouring, a dedicated flow medium or pouring medium is essential. It maintains paint viscosity while allowing cells to form and colours to blend without losing opacity. Products like Mont Marte or Nicpro are popular choices for this technique.
