Wetting agent Oxgall for watercolors and gouache colors. It is used to improve flow when mixed directly with watercolors on surfaces which are difficult to wet and can be used from very hard sized papers to ease surface tension. Dilute the product with a little water and mix it into the watercolors separately on a palette.

• Mixable with watercolors.
• Improves flow of watercolors.
