Acrylic paint is a versatile and fast-drying medium, which is why it's a favorite among artists of all skill levels. However, understanding how long acrylic paint takes to dry can help you better plan your projects and avoid frustrating smudges or surface damage. In this guide, we'll cover the factors that influence drying time, how to tell when acrylic paint is fully dry, and what products can help you control the process.
Acrylic paint typically dries to the touch within 10 to 30 minutes on most surfaces. However, this estimate can vary significantly based on factors like paint thickness, environmental conditions, and surface type. A thin layer of acrylic on canvas may dry within 15 minutes, while a thicker, textured stroke may take over an hour. Fully curing—meaning the paint has dried completely throughout—can take up to 24 hours.
For artists who need quick results, using fast-drying acrylics or working in thin layers can speed up the process. To explore fast-drying options, browse our acrylic paints collection.
Drying time can be heavily influenced by the environment. Acrylic paint dries faster in warm, dry conditions and slower in humid or cold environments. Here are some factors to consider:
Temperature: Ideal range is between 18–24°C (64–75°F). Lower temperatures slow drying.
Humidity: High humidity levels can delay drying by several hours.
Airflow: Good ventilation helps moisture evaporate from the paint faster.
Lighting: Natural light can slightly speed up drying, especially under warmth.
To control your working environment, use fans, dehumidifiers, or climate control if you're painting indoors. This is especially helpful when working on time-sensitive commissions or multi-layered projects.
Touching the surface isn’t always a reliable way to determine if the paint is completely dry. While the surface may feel dry, the layers underneath could still be moist. A fully cured acrylic painting:
Shows no soft spots when gently pressed
Doesn’t leave fingerprints
Has a consistent matte or glossy finish (depending on the paint)
If you're planning to apply a second layer, varnish, or a protective coating, it's best to wait at least 24 hours after the final brushstroke to avoid smudging or clouding.
Depending on your project, you may want to either accelerate or slow down the drying time of acrylics. Here’s how:
Use a hairdryer on low heat, holding it 15–20 cm away from the surface.
Apply thinner layers of paint.
Choose fast-drying brands or formulas.
Work on absorbent surfaces like cotton canvas.
Add a retarder medium or use a stay-wet palette.
Mix in slow-drying acrylic mediums to extend working time.
Work in a cool, humid space to reduce evaporation.

Whether you're a hobbyist or a professional, using the right tools and products makes a big difference. Here are a few recommended items available at The Sydney Art Store:
Acrylic Retarder Mediums – For slowing down the drying process.
Heavy Body Acrylics – For thicker textures and longer drying.
Stay-Wet Palettes – Ideal for extended sessions without drying out.
These tools allow greater flexibility in blending, layering, and fine detail work.
