Acrylic paints stand out due to their rapid drying times, vibrant colors, and versatility on various surfaces like canvas, paper, and fabric, making them a favorite among artists 1. Understanding how long it takes for paint to dry is crucial as acrylics often appear darker once dry and differ from oil paints by drying within minutes, enhancing their appeal for fast-paced projects 1.
Exploring the factors influencing acrylic paint drying times offers insights into achieving desired effects and mastering techniques such as diluting with water for varied textures 2. This article delves into average drying times for acrylic paint, techniques to expedite drying and practical tips for artists keen on optimizing their painting process with acrylic paints 3.

Factors Influencing Acrylic Paint Drying Times
Understanding the myriad factors influencing the drying times of acrylic paints is essential for artists to plan and execute their work effectively. These factors can be broadly categorized into environmental conditions, paint characteristics, and the nature of the painting surface.
- Environmental Conditions:
- Temperature and Humidity: Acrylic paint dries faster in conditions that are dry and warm 4578. Optimal conditions include temperatures around 70 to 90°F and humidity levels under 75% 8. Conversely, high humidity and low temperatures can significantly slow down the drying process 59.
- Air Movement: Increased air movement, such as using a fan, can help accelerate the drying time 5.
- Paint Characteristics:
- Thickness of Application: Thicker layers of paint will naturally take longer to dry compared to thinner applications 45.
- Color: It has been observed that darker colors may take longer to dry than lighter ones 4.
- Additives: The use of paint additives like retarders can be employed to deliberately slow the drying time of acrylic paints 5.
- Specific Paint Types: Products like GOLDEN OPEN Acrylics are formulated to have slower drying times to meet specific artistic needs 6.
- Painting Surface and Studio Conditions:
- Substrate Absorbency: Surfaces that are more absorbent, such as uncoated hot-pressed watercolor paper, offer significantly less working time due to rapid moisture-wicking 56. Preparing surfaces with a sealant or gesso can provide more working time 5.
- Studio Climate: The overall climate of the studio, including temperature and airflow, plays a dramatic role in the curing rates of acrylic paint 6.
By considering these factors, artists can better manage their working times and achieve the desired effects in their acrylic paintings.
Average Drying Times for Acrylic Paint
Understanding the average drying times for acrylic paint is crucial for artists to manage their workflow efficiently. The drying time can vary significantly based on the type of acrylic paint used and the thickness of the application:
- Galeria Acrylic:
- Professional Acrylic:
The process of drying occurs in two main stages. Initially, a skin forms over the surface quickly, followed by a longer period needed for the paint’s entire thickness to dry thoroughly 8. For a basic understanding:
- To the Touch: Acrylic paint generally dries to the touch within 20 to 30 minutes for basic acrylics, and 30 to 60 minutes on average 49.
- Full Cure: The paint fully cures in 3 to 4 days, allowing for additional layers once the surface is dry to the touch 9.
- Varnishing: Varnish can be applied after a minimum waiting period of 4 days, though waiting a week or two ensures the paint is completely dry, enhancing the painting’s longevity and appearance 912.
Specialty acrylics like Golden Open Acrylic and Atelier Interactive offer unique drying times, with the former taking up to two days to dry and the latter able to be reactivated with water or unlocking medium 7. This variability underscores the importance of artists familiarizing themselves with the specific properties of the acrylic paints they choose to work with.
Techniques to Speed Up Drying Time
To expedite the drying time of acrylic paints and maintain smoothness in the artwork, adopting various techniques can significantly impact the outcome. Here are some effective strategies:
- Temperature and Airflow:
- Ensure the painting area is within the ideal temperature range of 70 to 90°F and maintain relative humidity under 75% for optimal drying conditions 8.
- Using a fan to create moderate airflow over the work zone can speed up drying, with the heat from the fan aiding in the process. However, avoid excessive ventilation to prevent the paint from becoming wet 13.
- Application Techniques:
- Mix Winsor & Newton Fluid Retarder with the paint to extend its open time, allowing for longer workability 11.
- Apply thin layers of paint to ensure even and rapid drying. If necessary, a hairdryer on a low heat setting can be used to gently dry the paint, but caution is advised to prevent overheating 1415.
- Environmental Adjustments:
- Increase room ventilation by using fans or opening windows to improve air circulation, which helps in faster drying 15.
- A dehumidifier can be beneficial in reducing room humidity, further aiding the drying process 17.
- For longer-term projects, Winsor & Newton Acrylics Palette keeps colors usable for days when the paper is kept moist, and the lid is securely replaced after each session 11.
Implementing these strategies allows artists to effectively manage the drying times of acrylic paints, contributing to a more efficient and enjoyable painting experience.

FAQs
What is the drying time for acrylic paint? Acrylic paint drying times can vary. For Galeria Acrylic paints, thin layers typically dry within 10 to 20 minutes, while thicker applications may take an hour or more. With Professional Acrylic paints, thin layers dry in about 20 to 30 minutes, and thicker layers might take between one to two hours.
How can the drying process of acrylic paint be sped up? To quicken the drying process of acrylic paint, apply gentle heat using a hairdryer or heat gun set on low. Keep the device at a safe distance from the artwork to avoid damaging the surface. This is an effective method for artists working on canvas or smaller pieces.
What is the method to determine if acrylic paint has cured? To check if acrylic paint has cured, gently press on the painted surface with your fingernail or the edge of a knife. If the paint is not yet cured, it will leave an indent. A fully cured paint surface will not indent and will feel hard to the touch.
Should acrylic paint be allowed to dry before adding more layers? When layering acrylic paint, especially if planning to apply oil paints over an acrylic base, it is important to allow adequate drying time. Thin layers on canvas should dry for at least 1 to 3 days to ensure the paint has fully cured before adding additional layers.
