Rubbery acrylic paint is a common issue that can occur when working with acrylic paints. Acrylic paint is a popular choice for artists because it is versatile and easy to use, but it can sometimes become rubbery or gummy when not applied correctly.
There are several reasons why acrylic paint may become rubbery. One common cause is using too much medium, which is a liquid that is added to the paint to thin it and improve its flow. If too much medium is used, the paint may become too thin and lose its integrity, resulting in a rubbery texture.
Another reason why acrylic paint may become rubbery is if it is not allowed to dry completely before the next layer is applied. Acrylic paint dries quickly, but it still needs time to fully cure and harden. If additional layers are applied before the previous layers have fully dried, the paint may become rubbery.
Applying paint too thickly can also cause it to become rubbery. Acrylic paint should be applied in thin layers to allow it to dry and cure properly. If it is applied too thickly, it may take longer to dry and may not cure properly, resulting in a rubbery texture.
Finally, using low-quality acrylic paint may also contribute to rubbery paint. Poor-quality paints may not dry and cure properly, resulting in a rubbery texture. It is important to use high-quality acrylic paints to ensure that your finished artwork looks its best.
Causes of Rubbery Acrylic Paint
Using Too Much Medium
When mixing acrylic paint, it is important to use just the right amount of medium. Acrylic paint is a water-based medium, and it can be thinned with water or a medium such as a flow improver or gloss medium.
However, adding too much medium can cause the paint to become too thin and lose its integrity, resulting in a rubbery texture. To avoid this, it is recommended to start with a small amount of medium and add more if needed.
Not Allowing the Paint to Dry Completely
Acrylic paint dries quickly, but it still needs time to fully cure and harden. If additional layers are applied before the previous layers have fully dried, the paint may become rubbery.
This is because the layers are not able to properly bond and set, resulting in a rubbery texture. To avoid this, it is recommended to wait until each layer is completely dry before applying the next one.
Applying Paint Too Thickly
To achieve the best results, acrylic paint should be applied in thin layers. Applying paint too thickly can result in a rubbery texture due to the longer drying time and incomplete curing. When the paint is applied too thickly, it may take longer to dry and may not cure properly, resulting in a rubbery texture.
To avoid this, it is recommended to apply the paint in thin layers and allow each layer to dry completely before adding the next one.
Using Low-quality Acrylic Paint
The quality of the acrylic paint you use can greatly impact the final outcome of your artwork. Poor-quality paints may not dry and cure properly, resulting in a rubbery texture. To avoid this, it is important to use high-quality acrylic paints that have been specifically designed for artists and that have been tested for their ability to dry and cure properly.
Importance of Using High-quality Acrylic Paint
To ensure a properly cured and dried finished artwork, it is important to use high-quality acrylic paints. High-quality acrylic paints are formulated to dry and cure properly, resulting in a final product that is durable and long-lasting. Using high-quality acrylic paints will also ensure that your artwork looks its best and that the colors remain vibrant and true to life.
How to Fix Rubbery Acrylic Paint
If you find that your acrylic paint has become rubbery, there are several steps you can take to fix it. Here are four options for fixing rubbery acrylic paint:
Option 1: Add a Flow Improver
Flow improver is a medium that can be added to acrylic paint to improve its flow and reduce brushstrokes. If your paint has become rubbery, adding a flow improver may help to thin it and improve its consistency. Simply mix a small amount of flow improver into the paint and test it on a scrap piece of paper before applying it to your artwork.
Option 2: Thin the Paint With Water
If the paint is too thick and has become rubbery, adding a small amount of water can help to thin it and improve its consistency. Simply mix a small amount of water into the paint and test it on a scrap piece of paper before applying it to your artwork. Be sure to use only a small amount of water, as adding too much can cause the paint to become too thin and lose its integrity.
Option 3: Use a Heat Gun or Hair Dryer to Soften the Paint
If the paint is still wet, you can use a heat gun or hair dryer to soften it and improve its consistency. Simply hold the heat gun or hair dryer a few inches away from the paint and use a low heat setting. Be careful not to hold the heat gun or hair dryer too close to the paint, as this can cause it to bubble or blister.
Option 4: Sand the Paint to Remove the Rubbery Layer
If the paint has already dried and become rubbery, you may need to sand it down to remove the rubbery layer. Use fine-grit sandpaper to gently sand the surface of the paint until it is smooth. Be sure to sand evenly to avoid creating dips or uneven areas in the paint. Once you have sanded the paint, you can then apply additional layers of paint if necessary.
It may take a bit of trial and error to find the best solution for fixing rubbery acrylic paint. Be patient and experiment with different techniques until you find one that works for you.

FAQs
Here are some additional frequently asked questions about working with acrylic paint:
Yes, you can use oil paints over acrylic paint, but it is important to allow the acrylic paint to dry completely first. Acrylic paint dries quickly, typically within an hour or two, but it may take longer to fully cure and harden. It is recommended to wait at least 24 hours before applying oil paints over acrylic paint to ensure that the acrylic paint has had sufficient time to dry and cure.
Technically, it is possible to mix acrylic paint with oil paint, but the resulting paint will not have the same properties as either acrylic or oil paint. Acrylic paint is water-based, while oil paint is oil-based, so the two types of paint do not mix well. Instead of mixing the two types of paint, it is generally recommended to use one or the other or to use a medium such as a glaze or a thin layer of oil paint over a layer of acrylic paint.
Yes, you can thin acrylic paint with water. Acrylic paint is a water-based medium, so it can be thinned with water to achieve the desired consistency. However, it is important to be careful not to add too much water, as this can cause the paint to become too thin and lose its integrity. To thin acrylic paint with water, start by adding a small amount of water to the paint and stirring it well. Then, add more water as needed until the paint reaches the desired consistency.
Yes, you can use acrylic paint on wood. Acrylic paint is a versatile medium that can be used on a variety of surfaces, including wood. Before painting, it is important to prepare the wood surface by sanding it smoothly and applying a primer to help the paint adhere to the surface.
Once the primer has dried, you can then apply acrylic paint to the wood using a brush or roller. Be sure to allow the paint to dry completely before adding additional layers or applying a sealant.
Acrylic paint should be stored in a cool, dry place away from direct sunlight. It is best to store acrylic paint in airtight containers to prevent it from drying out. If the paint has become thick or clumpy, you can thin it with a small amount of water or a medium such as a flow improver to restore it to its original consistency. It is also important to keep the lids of the paint containers tightly sealed to prevent the paint from drying out.
Editor’s Note
It sounds like you are trying to paint a toy or miniature that is made of soft plastic or hard rubber. When painting these types of materials, it is important to consider the flexibility of the material and the type of paint you will be using.
Spray primer may not adhere well to a soft plastic or hard rubber due to the flexing of the material. In this case, you may want to try using a brush-on primer or gesso, which is a type of primer specifically made for use on porous surfaces such as canvas or paper. Gesso is also flexible and may be a better option for priming soft plastic or hard rubber miniatures.
Once you have primed the miniature, you can then paint it using acrylic paints. Acrylic paints are a good choice for painting soft plastic or hard rubber because they are flexible and will not peel off like some other types of paint. Just be sure to use thin layers and allow each layer to dry completely before adding additional coats.
If you are concerned about the paint adhering to the miniature, you may also want to consider using a sealant or varnish to protect the paint and help it adhere to the surface. There are several types of sealants and varnishes available, so be sure to choose one that is appropriate for use with acrylic paints.
In general, it is important to take your time and be patient when painting soft plastic or hard rubber miniatures. Using the right primer and paint, and allowing each layer to dry completely, can help ensure that your finished miniature looks great.
