Gum Arabic is a binding agent used for own production of aquarell/ watercolor paints and gouache paints. You can dilute the agent with water if you want and you can also dilute the finished color if you prefer. We recommend that you start with half GumArabic and half pigment and then add more Gum Arabic in small stages until you are happy with the result. The paint should be smooth and you shouldn't be able to scrub it off the surface when it has dried.
You can also use this product with watercolor paints and gouache paints to make the paint adhere better to the surface you are going to paint. This also makes the color more glossy, transparent and intense.
