The Average Drying Time of Oil Paint
The average drying time of oil paint depends on numerous controllable and uncontrollable factors. In general, oil paint takes 24 hours to a week to dry. However, some outliers may take months to completely dry. Regardless of the drying time, You must wait a minimum of six months after completion to display your oil painting. The chemical makeup of the paints can make them susceptible to smudging even after drying.
Factors That Determine the Drying Time of Your Oil Painting
As mentioned previously, many factors contribute to your oil painting’s dry time. A few controllable factors are lighting and temperature, color, thickness, age and brand, and the use of mediums or paint thinners.
Lighting and Temperature
The setting of your work area is critical to creating your art piece. You want a warm and arid, well-lit room for optimal drying times and painting results. If you are painting in a dark, cold, humid room, it will take longer to complete and may not dry properly.
Color of Paint
Different colors of oil paints have varying drying times. For instance, reds and blacks tend to fall under the slower colors, while yellows and blues are nearly always fast. Knowing factors like this in advance will help you avoid making mistakes, and you can paint specific colors at the same time if they have a similar drying time.
Thickness of Layers
Similar to other paint forms, the thicker the layer, the longer the drying process. Layering oil paints is a favorite technique among painters, but you may want to consider using thinner layers if you are under a time constraint.
If you want to use thicker layers of oil paint, remember that some colors will take longer to dry, so you will need to plan ahead if you want to trim down the overall drying time.
Age and Brand
When choosing your oil paints, it is critical to check the age and brand. Old oil paints are not as effective as new ones. Additionally, each brand tailors its oil paint toward specific genres of painters. Some are made for beginners, while others are for experts or painters who focus on particular techniques.
Another factor to consider with brands is the oil used to make the paint. Some oils dry faster than others. Research your brand before purchase to ensure that it is the right fit for you and your painting.
Use of Medium or Paint Thinner
You can better control the drying time of your painting by mixing your paints with a medium or paint thinner. Consider combining your paints with turpentine, liquin, or Cobalt Driers to lessen drying time. Metal substrates like copper or lead added to the oil paints can also reduce the drying time. Another method to speed up the process is painting your base with acrylic paints.
Testing if Your Painting Is Dry
Oil paints are more difficult to determine dryness than other paint mediums. You will not be able to ascertain if it is dry by looking at the painting. Touching to test is not recommended as it could smudge your paint or give you a false sense of completed dryness.
One recommendation is to use a razor blade and lightly scrape the paint. If it comes off as a powdery substance, your painting is dry. Remember that dry does not mean finished like with other paints. You will still have to wait a few months for it to be completely set.
The Drying Process of Oil Paints Compared to Other Paints
The reason oil paints take longer to dry compared to acrylics or watercolors has to do with the chemical process involved in drying. Acrylic and watercolor paints are water-based, meaning they dry through a water evaporation process.
On the other hand, oil paints go through a chemical process called autoxidation. This process involves a molecular weight change and a chemical alteration of the paint. It is extensive, involves multiple steps, and takes weeks to months to complete.
Autoxidation is why even after your oil painting is fully dry, you cannot varnish it. The process continues even after the paint is dry, making it susceptible to smudging for months after completion.
The Fastest Method for Drying Your Oil Painting
The fastest method for drying your oil painting is to create the optimal environment to dry. Follow these steps to dry your oil painting quickly.
- Ensure your workspace is well-lit and warm, but do not expose it to direct sunlight.
- Use colors that dry faster and paint with thin layers.
- Be sure to choose the right brand of paint for your project.
- Mix your oil paints with a medium or paint thinner.
- If you must use a slower drying paint, you can mix it with acrylic paint or a metal substrate like copper or lead.
Final Words
Artists have used oil paints for centuries because of their unique qualities that produce extravagant paintings. One downside of oil paints is their drying time. An oil painting can take anywhere from days to months to completely dry. Various factors contribute to a painting’s drying time.
Regardless of the official drying time, oil paintings are not ready to display for at least six months after completion due to the smudging that could still occur from the ongoing chemical process involved in oil paints.
