Understanding Acrylic Paint
Acrylic paint is a popular medium for artists due to its versatility and durability. It is water-soluble, fast-drying, and can be used on a variety of surfaces, including canvas, paper, and wood. Understanding the properties of acrylic paint can help you achieve the desired thickness and texture for your artwork.
Acrylic paint can be opaque or transparent, depending on the pigments used. Opaque colors cover the underlying surface completely, while transparent colors allow the surface to show through. Acrylic paint can also be thinned with water to create a watercolor-like effect.
The consistency of acrylic paint can vary depending on the type of paint you are using. Heavy body acrylics have a thick, buttery consistency and are ideal for creating textured paintings. Fluid acrylics have a thinner consistency and are better suited for techniques such as pouring and glazing.
Basics of Thickening Acrylic Paint
If you have ever painted with acrylics, you may have noticed that sometimes the paint can be too thin or watery. This can make it difficult to achieve the desired texture and finish. Fortunately, there are several ways to thicken acrylic paint to make it easier to work with.
One of the simplest ways to thicken acrylic paint is to use a thickening agent. There are several options for thickening agents, including specialized gel mediums, paste medium, cornstarch, talcum powder, and even baking soda. These agents work by absorbing the excess water in the paint, making it thicker and more manageable.
When using a gel or paste medium, it is important to choose the right type for your project. Some mediums are designed for heavy body acrylics, while others are better suited for fluid or soft body acrylics. Be sure to read the label carefully and choose a medium that is compatible with your paint.
Like mentioned previously, another way to thicken acrylic paint is to add a DIY thickener. Common household items such as talcum powder, diatomaceous earth, and flour can be mixed with acrylic paint to create a thicker consistency. However, it is important to note that adding too much thickener can affect the transparency of the paint.
Overall, thickening acrylic paint is a simple process that can help you achieve the desired texture and finish in your artwork. Whether you choose to use a thickening agent or a gel medium, be sure to follow the instructions carefully and experiment to find the right consistency for your project.
Now that we've covered the basics of acrylic paint and how to alter the thickness of it, let's go a little bit deeper into each of the thickening agents so you are better able to choose the best one for your needs.
Using Acrylic Mediums for Thickening
One of the easiest and most effective ways to thicken acrylic paint is by using acrylic mediums. Acrylic mediums are specifically designed to be mixed with acrylic paint to alter its consistency, texture, and drying time.
There are several types of acrylic mediums that can be used for thickening acrylic paint, including acrylic polymer, acrylic gel mediums, and thickening mediums. These mediums can be mixed with acrylic paint to create a thicker, more textured paint that is ideal for impasto techniques and other applications.
Acrylic gel mediums are one of the most popular types of mediums used for thickening acrylic paint.
They come in a variety of textures, including gloss gel, matte gel, and semi-gloss gel. These gels can be mixed with acrylic paint to create a thicker, more textured paint that is ideal for creating impasto effects and other techniques.
If you are an acrylic pouring artist and you've thinned down your fluid paint mixes a little too much, you can thicken them up by adding some gel medium along with some more acrylic paint into your paint/pouring medium mix until you get it back to the correct consistency.
Another popular type of acrylic medium for thickening paint is gesso. Gesso is a type of primer that is used to prepare surfaces for painting. It can also be mixed with acrylic paint to create a thicker, more textured paint that is ideal for impasto techniques.
When using acrylic mediums to thicken paint, it is important to follow the manufacturer's instructions carefully. Some mediums may require a specific ratio of medium to paint, while others may require a specific drying time.
It is also important to experiment with different textures and consistencies to find the right combination for your specific needs.
Overall, using acrylic mediums for thickening paint is a simple and effective way to create a thicker, more textured paint that is ideal for a variety of techniques and applications. With a little experimentation and practice, you can create beautiful, textured paintings that are sure to impress.
Thickening with Modeling Paste
Modeling paste is an excellent option for thickening acrylic paint. It is a thick, white paste that is commonly used to add texture to paintings. It is also known as molding paste or modeling pastes. It is made of a mixture of marble dust, acrylic polymer, and other additives.
Here are the steps to thicken acrylic paint with modeling paste:
- Start with a small amount of modeling paste. You can always add more if needed.
- Use a putty knife to scoop out the modeling paste and add it to your paint.
- Mix the modeling paste and paint thoroughly with a palette knife or a brush.
- Keep adding modeling paste until you reach the desired thickness.
It is important to note that modeling paste will not change the color of your paint. It will also not affect the finish of your paint.
One advantage of using modeling paste is that it can be used to create texture in your paintings. You can use it to create impasto effects or to add three-dimensional elements to your artwork.
When working with modeling paste, it is important to keep in mind that it dries slower than regular acrylic paint. This means that you will need to wait longer before you can add additional layers to your painting.
As you can see, modeling paste is an excellent option for thickening acrylic paint. It is easy to use and can be used to add texture to your paintings.
Just remember to mix it thoroughly with your paint and to wait for it to dry before adding additional layers.
Adding Texture with Household Items
If you don't have any thickening agents or acrylic mediums on hand or are looking for affordable options to thicken your acrylic paint, there are several household items you can use. These options are not only inexpensive but also readily available. Here are a few options:
- Flour: Mix flour with water to create a paste, then mix the paste with your acrylic paint. This can add texture to your paint, but it may also cause the paint to dry out faster or become lumpy.
- Talcum Powder: Add a small amount of talcum powder to your acrylic paint to thicken it. This can create a gritty texture in your paint, which may be desirable for certain applications. Keep in mind that adding too much talcum powder can make your paint grainy.
- Cornstarch: Add a small amount of cornstarch to your paint and mix it thoroughly until you achieve the desired consistency. However, be careful not to add too much cornstarch, as it can affect the color and finish of your paint.
- Baking Soda: Mix baking soda with water to create a paste, then mix the paste with your acrylic paint. This can add texture and thickness to your paint, but it may also cause the paint to dry out faster and will feel grainy.
- PVA Glue: One of the most popular options is PVA glue. It's a water-based adhesive that can be mixed with very thin acrylic paint to make it a bit thicker. But if your paint is already somewhat thick, PVA glue might actually thin it down instead of thickening it. You can add a small amount of PVA glue to your paint and mix it thoroughly until you achieve the desired consistency. Be cautious not to add too much glue, as it can affect the color and finish of your paint.
You can use other common household items such as coffee, diatomaceous earth, gelatin, and pectin to achieve the same thickening effect.
Keep in mind that using household items to thicken your acrylic paint may not produce the same results as using professional-grade thickening agents or mediums.
Additionally, some household items may not be as durable or long-lasting as their manufactured counterparts, and may flake off or even mold on your canvas over time.
If you're looking for a more durable solution, consider investing in acrylic gel mediums or modeling pastes, which are specifically designed to thicken and add texture to acrylic paint.
Using Sand and Sawdust
If you're looking for a cheap and easy way to thicken your acrylic paint, look no further than your own backyard! Sand and sawdust are two common household items that can be used to add thickness and texture to your paint.
Sand is a great option for creating a gritty texture in your paint. Simply mix a small amount of sand into your paint until you reach the desired consistency. Be careful not to add too much sand, as it can make your paint too thick and difficult to work with. Sand works best when mixed with thicker paints, such as heavy body acrylics.
Sawdust is another great option for adding texture to your paint. Simply mix a small amount of sawdust into your paint until you reach the desired consistency.
Sawdust works best when mixed with thinner paints, such as fluid acrylics. It creates a subtle, wood-like texture that is perfect for painting natural landscapes or rustic scenes.
If you're looking for a more abrasive texture, you can also try using pumice. Pumice is a volcanic rock that can be ground into a fine powder and mixed with your paint. It creates a rough, gritty texture that is perfect for painting rough surfaces like concrete or stone.
Remember, when using sand, sawdust, or pumice, it's important to mix your paint thoroughly to ensure an even texture. You may also want to experiment with different ratios of paint to texture medium to find the perfect consistency for your project.
Overall, using sand and sawdust is a simple and affordable way to add texture and thickness to your acrylic paint. Give it a try and see what creative possibilities it unlocks!

Achieving Different Finishes
Acrylic paint can be used to achieve a variety of finishes, from matte to glossy. The finish of your paint can have a big impact on the overall look and feel of your artwork, so it's important to choose the right finish for your project.
A matte finish has a low surface sheen and is often used for a more subdued, natural look. To achieve a matte finish with acrylic paint, you can use a matte medium. This will not only thicken your paint but also give it a matte finish.
A glossy finish has a high surface sheen and is often used for a more vibrant, eye-catching look. To achieve a glossy finish with acrylic paint, you can use a gloss medium. This will thicken your paint and give it a glossy finish.
A semi-gloss finish is somewhere in between a matte and glossy finish. It has a moderate surface sheen and is often used for a more balanced, versatile look. To achieve a semi-gloss finish with acrylic paint, you can use a semi-gloss medium. This will thicken your paint and give it a semi-glossy finish.
Luminosity refers to the way light interacts with the surface of your paint. A more luminous finish will reflect more light and appear brighter and more vibrant.
To increase the luminosity of your acrylic paint, you can use a high-gloss medium. This will thicken your paint and give it a high-glossy finish, which will reflect more light and increase luminosity.
In conclusion, achieving different finishes with acrylic paint is easy and can be done by using different mediums. By choosing the right finish for your project, you can create a more cohesive and visually appealing artwork.
Preserving Thickened Acrylic Paint
Once you have successfully thickened your acrylic paint, you will want to ensure that it stays in its thickened state for future use. Here are a few tips to help you preserve your thickened acrylic paint:
Store in an Airtight Container
One of the best ways to preserve your thickened acrylic paint is to store it in an airtight container. This will prevent air from getting to the paint and causing it to dry out or become thinner over time. Airtight containers can be found at most art supply stores and online retailers.
Thickened acrylic paint can be prone to sagging if it is applied too thickly or if it is not properly supported.
To avoid sagging, make sure that you apply the paint in thin layers and allow each layer to dry completely before applying the next. You can also use a support such as a canvas or board to help keep the paint in place.
Stir Before Use
Before using your thickened acrylic paint, make sure to give it a good stir. The thickening agents can settle at the bottom of the container over time, so stirring will ensure that the paint is evenly mixed and ready for use.
Keep in a Cool, Dry Place
Lastly, it is important to store your thickened acrylic paint in a cool, dry place. Exposure to heat or moisture can cause the paint to become thinner or even spoil. Keep your paint away from direct sunlight and make sure that the container is tightly sealed.
By following these tips, you can ensure that your thickened acrylic paint stays in its desired state for future use.
In conclusion, there are many ways to make your acrylic paint thicker without having to buy expensive thickening agents.
You can use common household items such as flour, cornstarch, coffee, sand, baking soda, PVA glue, joint compound, talcum powder, diatomaceous earth, baby powder, gelatin, and pectin to achieve the same thickening effect.
It is important to note that not all of these items will work for every project, and some may affect the finish or color of your paint. It is recommended to test a small amount of the mixture on a separate surface before applying it to your artwork.
If you prefer to use a specialized thickening gel designed for acrylic paint, you can find it at a hardware or arts and crafts store. These gels are specifically formulated to thicken acrylic paint without affecting its finish or color.
Remember to always mix your paint thoroughly and slowly add your thickening agent until you reach your desired consistency. Too much thickening agent can cause your paint to clump or become lumpy.
Experiment with different methods and find what works best for your project. With these tips, you can create incredible texture and depth in your acrylic paintings.
