What is watercolour medium used for?

Watercolour mediums commonly come as liquids or gels that can be mixed into watercolour paint to achieve increased transparency, different textures, increased gloss, pearlescence, and a slower drying process and more! Watercolour mediums can also be used in thinned acrylic paint to create varied effects. 


Do you need mediums for watercolour paint?

You don't need to add a medium to watercolour paint - you can still create a masterpiece on its own! But, if you want to change the characteristics of your paint, such as increased drying time, blending, gloss and transparency, textural effects,  and the effects of granulating, then you should opt for a watercolour painting medium. 


Can you use canvas for watercolour?

Yes, you can use watercolour paint and medium on a canvas. But first the surface must be primed with a Watercolour ground such as Daniel Smith Watercolour ground or Matisse Watercolour ground. Or you can use one that’s already primed such as the  Ampersand art panel to get the best results!
