Why you Should use a Pouring Medium for Acrylic Paint Instead of Water
Normally you would use water to thin your acrylic paintings. This works very well, doesn’t cost that much and is very easy. But water dilutes your colors, so it looks washed out. Too much water will also dilute the binding in your acrylic paints, so it doesn’t stick that well on your painting ground / your canvas. Also the drying isn’t that easy if you use too much water, because this can cause cracks when drying. Once dry, the colors also don’t look as vibrant as if you would use a Pouring Medium for acrylic paint. Using a such a medium will give you some benefits: It binds to the paint, the result will be more colorful and you can prevent your pouring from cracking.
If you use a Pouring Medium for acrylic paint, the surface will dry slower and prevent it from cracking by drying too fast. So you have more time to finish your pouring before it’s dry. At the end of this blog article, you’ll finde a pouring medium recipe for the right consistency of your pourin mixture.

Pouring Medium Recipe
Whats the ratio of pouring medium and acrylic paint? And do I have to add some water? These questions are not that hard to answer: We would suggest you to start with 1 part acrylic paint and 1 part medium. Mix them together and check if the consistency is equal to flowing honey. If so you’re ready to add some additive or start right away with acrylic pouring. If the consistency is too thick, add some more fluid medium or add some water and mix it again. Some Fluid Mediums are thinner, some thicker. Also the consistency of the acrylic paint you use varies. Just start with 1 part paint and 1 part medium and from there you have to find the right consistency. If the consistency is too thick, it won’t flow that good and the surface can probably crack. If your mixture is too thin, the surface isn’t stable enough and it will flow off your painting ground or canvas. Also your cells won’t last in your pourings. So consistency is your key to success. With this recipe you’ll find the desired consistency.
You can also try to mix different fluid mediums. Some of them are thinner, with some others you’ll get a shiny surface, some will dry matte. If you mix them together, you’ll definately learn more about them and get sometimes surprising results.
