Spray Paint dries faster than brushable paint. Therefore, it's a popular choice for DIY projects, but how much time does spray paint take to dry? Spray paint is a type of aerosol paint that usually takes between 5 minutes and 8 hours to dry and about 24 hours for a complete cure.
It comes in a can for convenience to give a smooth finish, free of brush strokes, on any surface, whether it's graffiti or something else. However, several factors affect the drying time, including the material, surface texture, type of paint, temperature, humidity, and airflow. So refer to this blog for detailed information about the factors affecting the drying times.
How Long Does Spray Paint Take to Dry?
Spray Paint usually needs 5 minutes to 8 hours drying time, which may vary depending on the type of paint, material, texture, and climate.
Type of Paint
Different types of paint have different drying times. Here are a few types of spray paint with their drying time.
| Type of Paint | Drying Time |
| Fast-Drying Spray Paint | 5 minutes |
| Epoxy Spray Paint | 30 minutes to 1 hour |
| Acrylic Spray Paint | 30 minutes to 2 hours |
| Rust-Preventive Enamel Spray Paint | 1 to 4 hours |
| Lacquer Spray Paint | 3 hours |
| Latex Spray Paint | 1 hour to 8 hours |
| Oil-Based Spray Paint | 6 to 8 hours |
Material and Texture
Drying time also depends on the type of material and the texture of the target surface. Here are some common materials, textures, and other surfaces with their drying time.
| Surface | Average Drying Time |
| Wood | 1 to 2 hours |
| Metal | 10 to 30 minutes |
| Plastic | 30 to 60 minutes |
| Other Surfaces | 1 to 2 hours |
| Rough and Porous Textures | NA |
Wood: Wood is often used for furniture. The finished wood used is semi-porous, but the untreated and unfinished woods are naturally porous. It will usually take an hour to dry and 24 hours to completely cure. However, drying time increases if you apply thicker coats. It means drying time can increase from 1 to 2 hours. Additionally, try to paint in an area with warm air and low humidity for quick drying. Plus, if you plan to paint outside, make sure to keep the surface away from dust and direct sunlight.
Metal: Metal surfaces tend to dry faster than wood because the material is nonporous. Generally, it takes around 10 to 30 minutes before you can touch the surface. But if you apply thin coats of paint, drying time may decrease. Additionally, remember that drying time can also increase if you paint in a cool or damp area.
Plastic: Plastic is nonporous and smooth. But, it takes more time to dry than metal but less than wood. You can expect 30 to 60 minutes of drying time. Additionally, avoid touching the surface unless it's completely dry.
Rough and Porous Textures: These surfaces take more time to dry than a nonporous and smooth one. They soak up the paint and take time to stick.
Concrete and Other Surfaces: The drying time of spray paint on surfaces like concrete, glass, ceramic, or fabric varies. Though, on average, it usually takes around 1 to 2 hours. However, ensure to test on a small area before beginning the painting job.
Climate Conditions
Drying time is also influenced by regional climate, including the temperature and humidity. Here is the calculated drying time of spray paint based on local climatic conditions.
Arid Climates: When the weather is windy and less humid, spray paint dries faster. However, if the humidity is too low, the paint might crack. So if you are painting indoors, set up a humidifier to increase the humidity so that the paint can dry without any issue.
Humid Climates: When the climate has a lot of moisture in the air, spray paint takes a long time to dry. It's best to paint indoors, where you can use a dehumidifier to lessen the moisture.
Warm Climates: Warm climates are the best time to apply paint, as paint dries quickly in warm weather. However, if it's applied in hot weather, paint can dry unevenly, crack, or blister.
Cold Climates: Cold climates can cause adhesion and drying issues. The drying time also increases in cold weather, which can even lead the paint to freeze or crack. Plus, longer drying times can also trap moisture and cause mold and mildew.
Factors that Affect the Spray Paint Drying Time
The type of solvent in the paint plays a huge role in how fast the spray paint dries. However, there are other factors that also affect the drying time. Here is the list:
Humidity: It plays a big role because paint dries faster when the air is dry. So, water-based paints dry quickly. However, some finishes, like lacquer, can turn foggy in high humidity, especially if the temperature is low.
Coating Thickness: A thin coat of spray paint dries quicker than a thick coat. Therefore, professionals prefer to spray many layers of a thin coat instead of a thick coat. This expedites the drying process and issues like clouding and dust buildup on the coating of the paint.
Temperature: Although paint dries quickly in warm temperatures, it can dry too fast, crack, or turn powdery if it's extremely hot. On the other hand, cold temperatures dry slowly and lead to issues like clouding.
Ventilation: A well-ventilated condition is best when you need the paint to dry quickly. For example, a fan running over the sprayed paint can set the paint in minutes. Additionally, while painting indoors, keep the windows open or run a fan to keep the air moving in the room and exhaust fumes outside the house. This can reduce drying time accordingly. On warmer days, paint outside the house.
Surface Texture: Paint dries faster on a smooth surface than it does on a textured surface.
Final Words
Spray paint is indeed easy to use, but the drying time varies depending on the surface you are painting. Interestingly, drying time may increase due to other reasons as well. So, if you plan to use spray paint, start the painting work when the weather is favorable to ensure quick drying.
