Understanding Acrylic Paint Properties
Before you start working with acrylic paint, it's crucial to understand its makeup and behavior. Understanding the properties of acrylic paint is essential to thinning it for acrylic pouring.
Components of Acrylic Paint
Acrylic paint is a water-based medium. Its primary components include:
- Pigment: The colorants used in acrylic paint. They can be organic or inorganic and are finely ground to create a powder. Pigments are mixed with the binder to create the paint. The amount of pigment used affects the paint's opacity and color intensity.
- Binder: The ingredients that hold the pigments together in acrylic paint and adheres to surfaces. They are responsible for the paint's adhesive qualities and determine its permanence and flexibility. Acrylic binders are made up of a polymer emulsion, which is a mixture of a polymer and water. The most common polymer used in acrylic binders is acrylic polymer.
- Mediums: Liquids added to alter viscosity, sheen, and drying time.
These elements work together to determine the paint's texture and how it reacts on your canvas.
So if you thin your acrylic paints with too much water, you can weaken the bonds between the binders and pigments which will cause all sorts of issues when your paint pour dries. That is why using a professional pouring medium is best!
Types of Acrylic Paints and Their Consistencies
Acrylic paints come in various consistencies/viscosities which also influence their flow and application:
- Heavy Body: Thick paint that retains brushstrokes and is ideal for impasto techniques.
- Soft Body: Creamy and smooth, suitable for general painting and smooth applications.
- Fluid Acrylics: Pourable paint that's good for detail work, staining, and watercolor techniques.
- Acrylic Ink: Highly fluid, ink-like paint used for fine details and airbrushing.
Understanding these types of paints and their difference in viscosity will help you determine how much water or pouring medium you will need. The thicker your paints are, the more water or pouring medium you will need to get them to the right consistency for your pours.
Selecting Appropriate Thinning Mediums
When it comes to acrylic pouring, achieving the right consistency of the paint is crucial. The paint needs to be thin enough to flow easily but not so thin that it loses its vibrancy and color intensity. The type of medium you choose will depend on your personal preference, the effect you are trying to achieve, and the type of paint you are using. Here are some of the most popular mediums used for thinning acrylic paint:
Water-Based Thinning Methods
Water is the simplest and most common medium used for thinning acrylic paint. It is readily available and easy to use. However, it is important to note that adding too much water can cause the paint to lose its vibrancy and adhesion. Therefore, it is recommended to add water in small increments and mix thoroughly until the desired consistency is achieved.
I personally prefer using a pouring medium rather than just plain water to thin down my paints to avoid paint cracking, adhesion problems, loss of color vibrancy, etc.
Using Professional Acrylic Mediums
Another way to thin acrylic paint is by using professional acrylic mediums. These mediums are specially designed to thin the paint, increase transparency, and improve flow while maintaining its color intensity and vibrancy. Acrylic mediums come in different types, such as gloss, matte, and satin. It is also available in different viscosities, such as heavy, medium, and light. You can experiment with different types of acrylic medium to find the one that works best for you.
Pouring Medium
Pouring medium is a specialized medium that is designed for acrylic pouring. It's a self-leveling medium that creates a smooth, even surface and helps prevent cracking and crazing. Pouring medium is also used to extend the drying time of the paint, which allows you to work with it for a longer period. When using pouring medium, it is important to follow the manufacturer's instructions for the correct mixing ratio.
Alternative Thinning Solutions
If you don't have access to acrylic or pouring mediums, you can use alternative thinning solutions. One option is Floetrol, a latex paint additive that helps improve flow and leveling. Another option is PVA glue (with a little bit of water), which is a common household adhesive that can also be used to thin acrylic paint. However, be aware that these options are not archivable, meaning your artwork might yellow over time. Your colors will also dry with a matte sheen when you use Floetrol or glue.
Remember that the key to achieving the right consistency is to add the thinning agent gradually and mix well. Don't rush the process, and take your time to ensure that the paint is the right consistency for your project. With these techniques, you can achieve beautiful, flowing acrylic pours that will impress everyone.
Popular Mediums in The Market
The medium you use for your paint pours will determine the final results of your piece. Some pouring mediums create awesome cells and patterns while others are better for creating marbling effects. Some dry to a matte finish while others might give your pour a satin or glossy look. Some are more suitable for professional artwork because they will stand the test of time but are usually more expensive, while others are best for those who just want to have fun and need something affordable.
Even though I have not tried every single medium out there, I have decided to compile a list of the most popular mediums on the market so you can easily glance over your options and decide which pouring medium is best for you.
Choose a pouring medium that will give you the sheen you desire, the durability that you need, the effects you want to create in your pours, and one that fits your budget. Be sure to read the reviews!

Achieving the Right Consistency
To get the perfect consistency for acrylic pouring, you need to mix your paint with a pouring medium or water. The ratio of paint to pouring medium can vary depending on the brand and type of paint you are using. The thicker your paints are, the more pouring medium that you will need.
It is essential to understand that the consistency of your paint should be like warm honey, motor oil, or chocolate syrup. If necessary, you can add some water to thin the paint further.
Understanding Ratios and Mixing
To achieve the right consistency, you need to understand the ratios of paint to pouring medium/water.
Some high-quality paint brands can be mixed with up to 30% water, while others can be mixed with up to 50%. So the amount of water that you will add will depend on your paint's water tolerance and the final viscosity that you desire for your paint mix.
When mixing your paint with pouring medium, it is important to understand that the brand you use and the initial consistency of your paint will determine the ratio of paint to pouring medium.
For example, if you use craft paints such as Deco Art Americana, you will most likely need a 1:1 ratio of pouring medium to paint. If you use tube paints like Liquitex Basics, Amsterdam Standard Series, and Pebeo Studio Acrylics, you will most likely use a 3:1 ratio of pouring medium to paint.
You might also need to add a little bit of water to your paint mixes to get them to the final desired consistency for your chosen pouring technique.
Also, avoid over-mixing, as this can introduce air bubbles into the mixture.
Troubleshooting Common Issues with Thinned Paint
Thinning acrylic paint is a great way to achieve the perfect consistency for acrylic pouring. However, it can also lead to some common issues if not done correctly. In this section, we will cover some of the most common issues you may encounter when working with thinned paint and how to troubleshoot them.
Avoiding Over-Thinning
One of the most common issues when working with thinned paint is over-thinning. Over-thinning can cause the paint to become too runny, which can lead to issues with adhesion and drying time. To avoid over-thinning, it is important to add small amounts of water or medium at a time and mix well before adding more.
Another way to avoid over-thinning is to use a pouring medium specifically designed for acrylic pouring. Pouring mediums are formulated to thin the paint to the perfect consistency without affecting the adhesion or drying time. Be sure to follow the manufacturer's instructions for the amount of medium to add to your paint.
Dealing with Adhesion and Drying Problems
Adhesion and drying problems can occur when working with thinned paint. These issues can lead to peeling, cracking, or uneven surfaces. To avoid these problems, it is important to use the right amount of paint and medium and to apply the paint to a properly prepared surface.
If you are experiencing adhesion problems, try adding a small amount of medium to your paint. This can help improve the bond between the paint and the surface. If you are experiencing drying problems, try adding a small amount of water to your paint. This can help the paint dry more evenly and prevent cracking.
In addition, be sure to apply the paint to a clean and properly prepared surface. This can help improve adhesion and prevent peeling. It is also important to allow the paint to dry completely before moving or touching the surface.
By following these tips, you can avoid common issues when working with thinned paint for acrylic pouring and achieve beautiful, smooth results.
