The world of painting is vast and varied, offering artists a plethora of mediums to express their creativity. One crucial factor that often influences an artist’s choice of medium is its drying time. A quick-drying medium can be advantageous for artists who prefer to work in layers, those with limited time, or those seeking to achieve specific effects. This article delves into the painting mediums known for their rapid drying properties, exploring their characteristics, techniques, and suitability for different artistic styles.
Understanding Drying Time in Painting
Before diving into specific mediums, it’s essential to understand what “drying time” truly means in the context of painting. Drying is not simply a matter of the paint becoming touch-dry on the surface. It involves a complex chemical process that varies depending on the medium’s composition.
Evaporation: This is the most straightforward type of drying, where the solvent (like water or mineral spirits) evaporates from the paint film, leaving the pigment and binder behind.
Oxidation: Some mediums, like oil paints, dry through oxidation. This involves a chemical reaction with oxygen in the air, which causes the paint to harden and form a durable film.
Polymerization: Acrylic paints dry through polymerization, where the acrylic polymer molecules link together to form a solid, plastic-like film.
The drying time is affected by various factors, including the thickness of the paint application, the ambient temperature, humidity levels, and the presence of additives or mediums that can accelerate or retard the drying process.
Acrylics: The Undisputed Champion of Quick Drying
When it comes to rapid drying, acrylic paints are generally considered the fastest drying of all commonly used painting mediums. Their water-based nature means that the water content evaporates relatively quickly, leaving behind a flexible and durable acrylic polymer film.
Factors Affecting Acrylic Drying Time
While acrylics are inherently fast-drying, several factors can influence the precise drying time.
Temperature and Humidity: Higher temperatures and lower humidity levels will accelerate the drying process. In a warm, dry environment, acrylics can dry to the touch in as little as 15-30 minutes. In contrast, in a cold, humid environment, drying may take considerably longer, potentially several hours.
Thickness of Application: Thin washes of acrylic paint will dry much faster than thick, impasto applications. A thick layer of paint has more water to evaporate, naturally extending the drying time.
Acrylic Mediums and Additives: Numerous acrylic mediums can alter the drying time. Retarders can slow down the drying process, allowing for more blending time, while quick-drying mediums can further accelerate it.
Type of Acrylic Paint: Different brands and formulations of acrylic paints may have slightly varying drying times. Heavily pigmented artist-grade acrylics might dry a little slower than student-grade paints due to the higher pigment concentration.
Techniques Suited for Fast-Drying Acrylics
The fast-drying nature of acrylics opens up a range of painting techniques.
Layering: Acrylics are ideal for layering techniques, allowing artists to build up colors and textures quickly. Because each layer dries rapidly, artists can apply subsequent layers without waiting for extended periods.
Dry Brushing: This technique involves using a dry brush with a small amount of paint to create textured effects. The quick-drying nature of acrylics prevents the paint from blending too much, resulting in a distinctive, scratchy texture.
Underpainting: Acrylics are often used for underpainting, providing a quick-drying base layer upon which artists can then apply other mediums, such as oils.
Advantages and Disadvantages of Acrylics
Acrylics offer several advantages, including their fast drying time, versatility, durability, and water-based cleanup. However, they also have some disadvantages.
Advantages:
- Fast drying time: Allows for quick layering and efficient workflow.
- Versatility: Can be used on a variety of surfaces.
- Durability: Creates a flexible and durable paint film.
- Water-based cleanup: Easy to clean brushes and other tools with water.

Disadvantages:
- Can dry too quickly: May not be suitable for artists who prefer extended blending time (though retarders can mitigate this).
- Color shift: Acrylics can sometimes darken slightly as they dry.
- Plastic-like appearance: Some artists find the plastic-like sheen of acrylics less desirable than the richer appearance of oils.
Alkyd Paints: A Faster Drying Alternative to Oils
Alkyd paints are a synthetic resin-based medium that offers a faster-drying alternative to traditional oil paints. Alkyd paints are essentially oil paints modified with alkyd resin, a synthetic polymer.
How Alkyds Differ from Oils
Alkyd paints share many of the characteristics of oil paints, including their rich colors, blendability, and ability to create luminous effects. However, they dry much faster than oils, typically drying to the touch within 18-24 hours, compared to the days or even weeks required for oil paints to dry completely.
The fast drying time is due to the alkyd resin’s rapid oxidation process. Unlike oil paints, which rely solely on oxidation for drying, alkyd paints dry through a combination of oxidation and polymerization.
Advantages and Disadvantages of Alkyds
Alkyd paints offer a compelling middle ground between the fast drying time of acrylics and the rich qualities of oil paints.
Advantages:
- Faster drying time than oils: Allows for faster layering and a more efficient workflow.
- Similar appearance and handling to oils: Retains the rich colors and blendability of oil paints.
- Durable paint film: Creates a strong and flexible paint film.
- Can be mixed with oil paints: Offers versatility in combining mediums.
Disadvantages:
- More expensive than acrylics: Alkyd paints are generally more costly than acrylics.
- Requires solvent cleanup: Requires mineral spirits or other solvents for cleanup, similar to oil paints.
- Can yellow over time: Some alkyd paints may yellow slightly over time, particularly in dark or poorly lit environments.
Techniques Suited for Alkyd Paints
Alkyd paints are well-suited for a variety of techniques, including:
Glazing: The relatively fast drying time of alkyds allows for the efficient application of multiple glazes, creating luminous and transparent effects.
Underpainting: Alkyds can be used for underpainting in oil paintings, providing a faster-drying base layer.
Alla Prima (Wet-on-Wet): While not as slow-drying as traditional oils, alkyds still allow for wet-on-wet techniques, enabling artists to blend colors directly on the canvas.
Watercolor: Fast-Drying but Easily Reactivated
Watercolor paints are known for their delicate washes and transparent qualities. While they dry relatively quickly, they are also easily reactivated with water, a characteristic that distinguishes them from other painting mediums.
Watercolor Drying Time and Reactivation
Watercolor paints dry primarily through evaporation. Thin washes can dry in minutes, while thicker applications may take longer. However, unlike acrylics and alkyds, watercolor paints do not form a permanent, waterproof film. They remain water-soluble even after they are dry.
This characteristic allows artists to lift colors, blend edges, and create soft, atmospheric effects. However, it also means that subsequent layers must be applied carefully to avoid disturbing the underlying layers.
Advantages and Disadvantages of Watercolor
Watercolor painting offers unique advantages and disadvantages.
Advantages:
- Fast drying time: Allows for quick layering and efficient workflow.
- Transparency: Creates luminous and delicate effects.
- Portability: Watercolor paints are lightweight and easy to transport.
- Relatively inexpensive: Watercolor paints are generally more affordable than oils or acrylics.
Disadvantages:
- Reactivation: The water-solubility of watercolors can make it challenging to apply multiple layers without disturbing the underlying layers.
- Less forgiving: Mistakes can be difficult to correct in watercolor painting.
- Susceptible to fading: Some watercolor pigments are susceptible to fading over time, especially when exposed to direct sunlight.
Techniques Suited for Watercolor
Watercolor painting is well-suited for a variety of techniques, including:
Washes: Applying thin, transparent washes of color to create backgrounds and atmospheric effects.
Dry Brushing: Using a dry brush to create textured effects on dry paper.
Lifting: Using a clean, damp brush or sponge to lift color from the paper, creating highlights and correcting mistakes.
Other Quick-Drying Options
While acrylics, alkyds, and watercolors are the most commonly used quick-drying painting mediums, other options are available.
Gouache: An Opaque Watercolor
Gouache is a water-based paint similar to watercolor but with the addition of an opaque pigment. This makes gouache more opaque than watercolor, allowing artists to layer colors and create solid, flat areas of color. Gouache dries relatively quickly, similar to watercolor.
Egg Tempera: A Traditional Medium with Rapid Drying
Egg tempera is a traditional painting medium made from egg yolk, pigment, and water. It dries very quickly, creating a durable and luminous paint film. Egg tempera was widely used before the advent of oil paints.

What is the fastest drying painting medium?
Acrylic paints are generally considered the fastest drying painting medium. They are water-based paints that dry through evaporation, unlike oil paints that dry through oxidation. This evaporation process is significantly faster, leading to acrylics often drying to the touch within minutes to hours, depending on the thickness of the application, ambient temperature, and humidity.
The rapid drying time of acrylics makes them ideal for artists who work in layers or who need to complete a painting quickly. However, it also means that blending and reworking the paint on the canvas can be more challenging compared to oil paints. Artists can use retarders to slow down the drying time of acrylics if they require more time for blending and manipulation.
How does the drying time of watercolor compare to acrylics?
Watercolor paints, similar to acrylics, are water-based and dry via evaporation. However, watercolors generally dry faster than acrylics, particularly when applied in thin washes. A thin wash of watercolor can dry within a few minutes, whereas even a thin layer of acrylic might take 15-30 minutes to dry completely. The difference stems from the binding agent: acrylics use a polymer emulsion that creates a thicker, more durable film as it dries.
While watercolors dry rapidly, they are also easily reactivated with water, allowing for adjustments and blending even after the paint has initially dried. This is a key difference from acrylics, which become permanent once dried and are resistant to being re-dissolved with water. This reactivatable quality makes watercolor ideal for techniques like lifting and glazing.
What factors affect the drying time of acrylic paints?
Several factors significantly impact how quickly acrylic paints dry. Thicker applications of paint naturally take longer to dry than thin washes. The ambient temperature and humidity also play a crucial role; warmer temperatures and lower humidity levels will accelerate the drying process, while cooler temperatures and higher humidity will slow it down.
Additionally, the specific type and brand of acrylic paint can influence drying time. Some acrylic paints contain additives that either speed up or slow down the drying process. Furthermore, using mediums designed to accelerate or retard drying times will directly affect how long it takes for the paint to dry to the touch and fully cure.
Can I speed up the drying time of my paintings?
Yes, several techniques can be used to speed up the drying time of paintings. For acrylics and watercolors, using a hairdryer on a low heat setting can gently accelerate the evaporation process. Ensure the hairdryer is kept at a reasonable distance to avoid cracking or damaging the paint film.
Another effective method is to ensure good ventilation in your workspace. Open windows or use a fan to circulate air, which will help evaporate the water content more quickly. For acrylics specifically, using a fast-drying medium designed to accelerate the drying process can also be beneficial. However, it’s essential to avoid applying excessive heat or direct sunlight, as this can cause the paint to dry unevenly or crack.
What are the advantages of using a quick-drying painting medium?
One of the main advantages of using a quick-drying painting medium is the ability to layer colors and techniques rapidly. This is especially useful for artists who prefer to work in multiple layers or who need to finish a painting within a limited timeframe. The fast drying time minimizes waiting time between layers, allowing for a more efficient and productive painting process.
Furthermore, quick-drying mediums are less susceptible to dust and other airborne particles settling on the wet surface. This can result in a cleaner and more pristine finish, reducing the need for touch-ups or corrections. They are also convenient for artists who need to transport their paintings quickly, as the reduced drying time minimizes the risk of smudging or damage during transport.
What are the disadvantages of using a quick-drying painting medium?
One significant disadvantage of quick-drying painting mediums is the limited time available for blending and reworking the paint on the canvas. Once the paint begins to dry, it becomes increasingly difficult to achieve smooth transitions and seamless blends. This can be challenging for artists who prefer to work with wet-on-wet techniques or who require a longer working time to refine their details.
Another potential drawback is the increased risk of creating hard edges or unwanted textures, particularly with acrylics. As the paint dries quickly, it can leave distinct lines or ridges, which may not be desirable for all painting styles. Artists using quick-drying mediums often need to work quickly and decisively, or employ techniques to slow down the drying time, to mitigate these potential issues.
Is gouache a quick-drying medium compared to oils?
Yes, gouache is considered a quick-drying painting medium, especially when compared to oil paints. Gouache is a water-based paint similar to watercolor but with the addition of an opaque pigment, which gives it a matte finish. Like watercolor and acrylic, it dries through evaporation, making it much faster drying than oil paints that dry through oxidation.
While gouache dries quicker than oils, it’s not quite as instantaneous as thin washes of watercolor. Depending on the thickness of the application, gouache can dry to the touch within minutes to an hour. Its relatively quick drying time, combined with its ability to be re-wetted and reactivated, makes it a versatile medium for artists who appreciate layering and correction techniques, offering a balance between the working time of oils and the speed of watercolors.
