The binder in commercially made watercolor paint is usually gum arabic, which is not easy to replicate at home. However, a few recipes out there use other ingredients like cornstarch or flour as a binder.

Although it may not be as strong and proper as the commercially made watercolor paint, it is possible to make it at home. And if you can mix all the ingredients properly, you can get better paint without spending too much money on it. However, it is not a permanent solution for making watercolor paint. You can use this method in an emergency. For example, if you are in the middle of painting something and run out of paints, this homemade method can continue your painting.

Now you have everything you need to make watercolor spray paint. Well, first, I am going to make watercolor paint and then thin it to use in a sprayer. Let’s dive into the detailed process.

  • First, take four tablespoons of baking soda and mix it with two tablespoons of vinegar. It will start fizzing, and wait until it stops fizzing.
  • Then add corn syrup and cornstarch as a binder and mix it well until cornstarch has dissolved properly. Make sure these four ingredients are mixed correctly, which will end up being a thick solution. And you did not add any color to it yet.
  • Well, let’s make it thin by adding water and mixing it. There is no right proportion for the water; it depends on your painting surface. Anyway, add water and make it as thin as possible.
  • Finally, add food color to give it the perfect color. And pour it into the sprayer to use in your painting. If you think it is too thick or thin, add water or baking soda to make it correct.
  • Now your watercolor spray paint is ready to use for your painting work.

Make your color in a pot to use later. And use the above proportion to get a perfect color. You should add food color later while pouring it into the sprayer to avoid wasting any color.

How Much Does It Cost To Make Watercolor Spray Paint

When you are willing to make watercolor paint at home, you do not need extra ingredients but some fluently available ingredients that you regularly use in your home. Suppose you buy these from the market that are going to cost around 50 bucks for making one liter of paint. And it is much less expensive than commercially available paints. Sometimes you can get cheaper pain bottles online than making them at home.

But the prime benefit of this homemade color is indeed more customization facility. If you think you need thick or thin paint, you can adjust it after adding some ingredients. As I said at the beginning, this is not the primary solution for watercolor spray paint; you can use it for emergency cases. Making homemade watercolor spray paint is not expensive but efficient from that perspective.

Can You Use Watercolor Paint As Regular Paint?

Watercolor paint is a type of paint that uses water as a solvent to bind the pigment to the surface. Because of the water content, it is usually translucent and can be used to create soft, gradual washes of color. It is also possible to achieve a wide range of tones and effects by varying the amount of water used.

Can You Use Watercolor Paint As Regular Paint

Usually, acrylic paint is the main competitor of watercolor paint. However, there is a significant difference between watercolor and acrylic paint. In terms of blending into the surface, watercolor has benefits over regular acrylic paint. Also, you can not make acrylic spray paint as easily as watercolor. Therefore watercolor is better for painting quickly. It dries quickly as well.

However, watercolor is not known for being long-lasting. It easily fades away, especially if you wash it with water. In contrast, regular paint is more of a permanent solution that lasts for a long time.

So the answer is that you can use watercolor paint as regular paint if you want better color mixing and to keep it away from the weather. But regular paint is for permanent painting with vibrant color.


That was all about how to make watercolor spray paint. If you do not want to do all of these hassles, you can buy it online and use it right after opening the package. But making it at home is easy and efficient to achieve various color options as you need. Use this making procedure carefully, and do not spill paint all over the house. Use a larger bowl to make the basic paint, then add color later while pouring it into the spray bottle. This paint is easily washable, so wash it properly after using the bowl and other pots that you have used to prepare the basic paint. Finally, enjoy your painting!
