Looking for an easy homemade gesso with cornstarch recipe? Well, you are in the right place! My recipe is a simple and effective way to prepare your canvas for painting!
Why Use Homemade Gesso?

Gesso is more than just a surface preparation—it's the foundation that brings your artwork to life. Whether you're working with watercolors, acrylics, or mixed media, gesso provides the perfect textured surface for your creations to cling to.
Store-bought gesso can be pricey, but fear not! With this easy DIY recipe, you can whip up your own batch of gesso right at home.
Ingredients for DIY Gesso with Cornstarch
Here's a quick video I made for you showing you how to make your own gesso with cornstarch and baking soda. I also show you how to apply it to your canvas.
Before we get started, here's what you'll need:
- 3 parts Cornstarch
- 3 parts Baking Soda
- 1 part Glue (PVA or Mod Podge)
- 1 part White or Black Acrylic Paint
- 2-3 parts Water
Now, let's dive into the messy fun of creating your homemade gesso masterpiece!
Step-by-Step Instructions
In a clean container, combine 3 parts cornstarch and 3 parts baking soda. This forms the base of your gesso mixture. Using a plastic spoon, add 1 part glue to the cornstarch and baking soda mixture. Stir thoroughly until smooth and well combined.
For a white gesso, add 1 part white acrylic paint to the mixture. Stir until the color is evenly distributed, creating a creamy consistency.
Slowly add 2-3 parts water to the mixture, adjusting as needed to reach your desired consistency. The gesso should have a smooth, paint-like texture that spreads easily but is not too runny.
To ensure your gesso is just right, apply a small amount to a test surface. It should provide a gritty texture for your media to cling to.
If the gesso is too thick, add a bit more water. For a thinner consistency, mix in additional acrylic paint or cornstarch.
Storing Your Homemade Gesso
Transfer your homemade gesso to a clean, reusable container. Label it to avoid any confusion with other art supplies.
Tips for Using DIY Gesso:
- Experiment with Texture: Play around with the amount of cornstarch and water to create the perfect textured surface for your artwork.
- Customize Your Colors: For a colored gesso, swap out the white acrylic paint for your preferred color. Get creative with hues that complement your artwork.
- Apply in Layers: Allow each layer of gesso to dry completely before adding additional coats. This creates a solid foundation for your masterpiece.
