In this blog post, I’ll share helpful tips on how to rehydrate dried acrylic paint so that all those lovely creations don’t wind up forgotten in the depths of storage.
Let’s get started.
Acrylic Paint Properties
Acrylic paints are known for their vibrant colors, wide range of textures, and fast-drying capability.
While they may look like regular paints at first glance, acrylics have some unique properties that set them apart from other mediums.
One of the most noteworthy qualities of acrylic paint is its quick drying time – typically only a few minutes – which makes them ideal for use in busy studios or for quick touch-ups.
It can also make the colors “pop” when used on raw canvas painting surfaces, making it a popular choice for artists looking to add more depth and contrast to their works.
In addition to their speed, acrylic paints are incredibly versatile when it comes to their uses.
They can be used on a variety of surfaces, including paper, cardboard, wood, and fabric.
It is also water-resistant which makes it great for outdoor projects or paintings that may need to withstand moisture or humidity.
Acrylic paints are very durable and long-lasting compared to other types of paint, allowing for the colors to remain vibrant and true over time.
The paints are also non-toxic, making them safe for use in households with children or pets.

How To Revive Acrylic Paint
Revive your dried-out acrylic paint by adding a few drops of water or acrylic medium to the mixture. Stir well, and add more as necessary to achieve the desired consistency. Avoid adding too much water, as this can dilute the pigment and compromise the quality of the paint.
Reasons Acrylic Paints Dry
If you have dried up paint, here are some of the reasons why acrylic paints dry quickly:
i. Evaporation
As acrylic paint dries on the canvas, the volatile components in the paint evaporate as it is exposed to air.
This leaves behind only the solid particles that make up the pigment color and binder, allowing the paint to dry.
ii. Exposure to air
Acrylic paints must be exposed to air in order for them to dry. As the paint is exposed to oxygen, it oxidizes and the volatile components evaporate.
This leaves behind only the solid particles that make up the pigment color and binder, allowing the paint to bind to the canvas as it dries.
iii. Age
Over time, acrylic paints begin to dry out due to natural aging processes.
This is because the volatile components of the paint are slowly evaporating over time, leaving behind only the solid particles that make up the pigment color and binder.
As a result, older acrylic paints may take longer to dry than newer paints.
iv. Heat
Is acrylic paint heat resistant? Heat accelerates the drying time of acrylic paint, due to the increased rate of evaporation caused by higher temperatures.
This is because as heat is applied, the volatile components in the paint evaporate at a faster rate, which leaves behind only the solid particles that make up the pigment color and binder.

v. Humidity
While high humidity levels slow down the rate of evaporation and therefore lengthen the drying time, low humidity speeds up the evaporation process and causes acrylic paints to dry faster.
vi. Thinners
Acrylic thinners are solvents that are added to acrylic paint in order to make them easier to spread and apply.
These thinners evaporate as the paint dries, leaving behind only the solid particles that make up the pigment color and binder.
vii. Paint quality
High-quality paints will generally contain more pigment and binder, which makes them thicker and helps them to dry faster.
On the other hand, low-quality acrylic paints may not have as much pigment or binder, making them thin and taking longer to dry.
Signs That Acrylic Paint Is Dried Out
The signs that acrylic paint is dried out are easily recognizable. Some of the most obvious signs include the following:
Cracking or Flaking of Paint
Does acrylic paint crack? Hardened acrylic paint may start to crack and flake away from the surface it was applied.
This is caused by the paint becoming brittle and losing its adhesion to the surface.
It goes hand in hand with a hard texture since both indicate that the paint is no longer usable.
If it was applied on shoes, here’s how to prevent acrylic paint from cracking on shoes.
Color Fading
Another sign of acrylic paint drying out is the color becoming dull and losing its vibrancy. This occurs when paint loses its moisture, causing it to become chalky and faded.
It is also a sign that the paint will not adhere properly to surfaces, making it difficult to use for artistic works or other painting projects.
Change of Texture
As the paint dries out, it will also change in texture. This change ranges from becoming more stiff and rubbery to a powdery, chalky consistency.
If you notice such an occurrence, then the paint is no longer usable for its intended purpose.
Clumps of Paint
Clumps of paint can indicate that the acrylic paint is dried out. The clumps will be formed where the paint has lost its cohesion and become lumpy in texture.
This can also cause the paint to adhere less effectively and make it difficult to use for painting projects. Here is how to get lumps out of paint.
How to Rehydrate Acrylic Paint
If you are struggling to rehydrate acrylic paint, this section discusses some of the common ways of rehydrating acrylic paint you can try.
1. A drop or more of warm water
Water is the simplest and most cost-effective way to fix dry paint. Adding a few drops of water to the paint and mixing it thoroughly can help restore its consistency.
However, this method can also dilute the paint and make your acrylic paint watery, so it’s best to use it only for minor touch-ups.
Warm water works best since it softens the paint more quickly.
2. Use palette paper to keep acrylic paint wet
A palette paper is a disposable paper sheet that can be used to hold acrylic paint. This paper keeps acrylic paint wet on the palette and makes cleaning easier.
Simply place a sheet of palette paper on it and squeeze out the paint on top of it.
3. Add fluid acrylic medium
Acrylic medium extends the drying time and increases the transparency of acrylic paint.
Add a small amount of medium to hard acrylic paint can help restore its consistency and color, while also improving its adhesive properties.
Types of acrylic medium:
- Gel medium: Gel medium is useful for adding texture, body and volume to acrylic paints. It thickens the paint, making it easy to manipulate on canvas or other surfaces.
- Glazing medium: Adds a glossy sheen to acrylic paints while slowing their drying time. This makes it ideal for creating layers of color without disturbing the underlying layer.
- Matte medium: Useful for adding opacity of acrylic paint and decreasing the sheen. It also helps to add a matte, non-reflective finish that can protect your artwork from dirt, grime, and UV rays.
- Heavy gel medium: Increases the body and viscosity of acrylic paints making it ideal for creating thick, textured brush strokes on canvas or other surfaces.
- Soft gel medium: Increase the flexibility and adhesion of acrylic paints while improving their overall texture. It’s ideal for creating thin, even layers on canvas or other surfaces.
4. Isopropyl Alcohol
Isopropyl alcohol breaks down the polymer molecules in acrylic paint, making it more fluid and easier to work with.
To revive acrylic paint with alcohol, add a few drops of rubbing alcohol to the paint and mix it thoroughly.
If you decide to use this method, be careful as it may weaken the paint’s adhesive properties. I prefer you use it only for non-critical applications.
5. Make a mixture with oil paint
Acrylic paint can be mixed with oil paints to create unique colors and textures.
However, oil paints take longer to dry than acrylic paints, therefore mix the paints in small quantities and use them immediately.
To create a mixture with oil paint, add a small amount of oil paint to the acrylic paint and mix it thoroughly.
6. Acrylic glazing liquid
Acrylic glazing liquid, a specific type of acrylic paint thinner, is used to dilute acrylic paint, producing a transparent glaze.
It also serves to prolong the acrylic paint’s workable duration, making it perfect for blending and layering techniques.
To reactivate acrylic paint with glazing liquid, add a small amount to the acrylic paint and mix it thoroughly until it reaches the desired consistency.
7. Gesso
Gesso is a primer that can be used to prepare surfaces for painting with acrylics. It helps create a smooth, even surface and can also improve the adhesion of the paint.
To use gesso, apply a thin layer to the surface with a brush or roller and let it dry completely before painting.
8. Store acrylic paint in a cool, dry place
Store acrylic paint in a cool, dry place away from direct sunlight, as heat and light can cause the paint to dry out and deteriorate.
A basement, closet or cabinet that’s away from direct sunlight and heat sources is a good storage location.
Do not store acrylic paint in areas exposed to extreme temperatures or humidity, such as attics, garages or bathrooms.
Extremely low temperatures, such as subzero cold, have the potential to freeze acrylic paint, causing it to become fragile and susceptible to cracking.
It is advisable to steer clear of temperatures that fall below freezing point, specifically 32°F or 0°C.
9. Use a palette knife to mix acrylic paint before use
Using a palette knife to mix acrylic paint before use can help ensure that the pigment and water are evenly distributed throughout the paint.
This can help prevent the paint from drying out or becoming too thick or thin during use.
10. Use airtight Paint container to store acrylic paint
To prevent air exposure and evaporation, store the paint in an airtight pain container as this can cause the leftover paint to dry out.
Use containers with tight-fitting lids that can be securely sealed to keep the paint fresh for longer periods.
Glass jars or plastic containers with snap-on lids are good options for storing acrylic paint.
11. Clean the palette regularly
Cleaning the palette regularly can help prevent the build-up of dried-out paint and other debris that can contaminate fresh acrylic paint.
Simply wipe the palette clean with a damp cloth or paper towel after each use.
For stubborn stains or dried-out paint, use a scraper or palette knife to remove the debris before wiping the surface clean.
12. Use a wetting agent.
A wetting agent is a specialized product designed to help prevent acrylic paint from drying out on the palette.
Add a few drops of wetting agent to the paint to keep it wet and workable for longer periods, even in hot and dry environments.
13. Revive acrylic paint with commercial paint revivers
There are several commercial paint revivers available on the market that can help revive dried-out acrylic paint.
These products contain proprietary formulas that can help restore the moisture content and consistency of the paint, as well as its color and adhesive properties.
14. Acrylic flow improver
Flow improver is a liquid additive that helps thin the consistency of acrylic paint, making it easier to apply and blend with other colors.
When added to an already dried-out paint, it can help restore some of its original fluidity.
15. Store the paint upside down to prevent air exposure
Storing acrylic paint upside down can help prevent air exposure and evaporation of water, which can cause the paint to dry out.
The water in acrylic paint is heavier than the pigment, so storing the paint upside down can help keep the pigment and water mixed together.
16. Cover the palette with plastic wrap
Covering the palette with plastic wrap can help create an airtight seal that can prevent the paint from drying out.
Simply cover the palette with plastic wrap after use and store it in a cool, dry place.
17. Use a retarder to slow down the drying process of acrylic paint
A retarder is a specialized product designed to slow down the drying time of acrylic paint.
Adding a few drops of retarder to the paint can help extend the working time, making it ideal for blending and layering techniques.
Retarder can also help prevent the paint from drying out on the palette, giving artists more time to work with the paint.
