Acrylic paint is a versatile medium that can be used on a variety of surfaces, from canvas to wood to metal. However, sometimes you may find that your acrylic paint is too thin and watery, making it difficult to work with. In this article, we will explore different techniques and tips on how to thicken acrylic paint to achieve the desired consistency for your artwork.
Why Would You Want to Thicken Acrylic Paint?
Before we dive into the techniques on how to thicken acrylic paint, let’s first discuss why you would want to thicken it in the first place. There are several reasons why you may want to thicken your acrylic paint:
- To create texture in your artwork
- To make the paint more opaque
- To improve the coverage of the paint
- To make the paint more suitable for impasto techniques
Now that we know why we would want to thicken acrylic paint, let’s explore some techniques on how to do it.
Techniques for Thickening Acrylic Paint
1. Add a Thickening Medium
One of the easiest ways to thicken acrylic paint is to add a thickening medium to it. A thickening medium is a substance that is added to the paint to increase its viscosity and make it thicker. There are several types of thickening mediums available, including:
- Gel medium
- Modeling paste
- Gloss medium
- Matt medium
To use a thickening medium, simply add a small amount to your acrylic paint and mix it thoroughly. Start with a small amount and gradually add more until you achieve the desired consistency. Keep in mind that adding too much thickening medium can make the paint too thick and difficult to work with.

2. Use a Palette Knife
Another technique for thickening acrylic paint is to use a palette knife. A palette knife is a flat, metal tool that is used for mixing and applying paint. To use a palette knife to thicken acrylic paint, simply scoop up a small amount of paint and mix it with the knife. The pressure and motion of the knife will help to thicken the paint and create texture.

3. Add Cornstarch
If you don’t have a thickening medium or palette knife on hand, you can also use cornstarch to thicken acrylic paint. Cornstarch is a common household item that can be used as a thickening agent in cooking and baking, but it can also be used to thicken paint.
To use cornstarch to thicken acrylic paint, simply mix a small amount of cornstarch with water to create a paste. Then, add the paste to your acrylic paint and mix it thoroughly. Keep in mind that adding too much cornstarch can make the paint too thick and difficult to work with.

4. Use a Drying Retarder
A drying retarder is a substance that is added to acrylic paint to slow down the drying time. This can be useful when you want to thicken the paint and create texture, as it gives you more time to work with the paint before it dries. To use a drying retarder to thicken acrylic paint, simply add a small amount to your paint and mix it thoroughly.
