When learning how to store oil paintings while drying you need to know that oil paint is notorious for taking a long time to dry. The exact length of time it takes depends on such factors as the quality of the paint, its foundational ingredients, and even its color. Oil paint will generally start to set after around eight hours, but a rough estimate of the total drying time is, at a bare minimum, 24 hours. However, it can take even longer than that to dry. So to make sure you don’t ruin your oil painting while it is drying there are two factors to consider, and I explain each below.
When storing your oil painting there are two things to consider:
- Temperature. Temperature is key for oil paint drying time so you will need to ensure wherever you are storing your oil paintings, that the room has a consistent temperature, preferably between 60 and 80 degrees F with low humidity as oil paints dry by having the oil oxidize and a lower humidity room will aid with this.
- Location. Store your oil paintings to dry in a room with a consistent temperature and humidity and use drying racks, vertical storage devices, flat filing cabinets, wooden crates or mirror boxes.
Artists who work on many different art projects at once can find themselves in a quandary about how to store their oil paintings during the drying process.
There are various ways to do this, such as adding spacers between a stack of canvas, using a climate-controlled room, and drying racks, but the reason the paint takes so long to dry should also be a consideration in which method works best for the particular painting.
How to store oil paintings while drying
When an artist accumulates a lot of oil paintings that are in various stages of drying, it is not a good idea to just leave them lying about. As previously discussed, wet oil paintings are vulnerable to elements, such as dust, pet hair, accidental fingerprints, and even variations in the weather.
Vertical storage devices
The best way to store an oil painting is to place it in a vertical position like you would store a book. A vertical drying rack can be found at virtually any art supply store, or they are easy to build with a simple board and evenly placed pegs that can hold the paintings upright.

Stacked drying racks
When stocking an art studio initially, the inclusion of a drying rack is a must-have. They come in many different sizes and configurations, but are basically racks, usually on wheels, that can hold paintings apart from one another as they dry.
Flat file cabinets
Flat file cabinets work the same way as racks. Only the paintings are in drawers that also help prevent dust accumulation that can ruin a painting.
Wooden crates and mirror boxes
Wooden crates and mirror boxes tend to be large and can safely hold oil paintings as they dry.
A climate-controlled rental storage unit is among the best places to safely store a drying oil painting. There, it will be left undisturbed, the climate control feature will keep it from temperature extremes, and, in most cases, the light can be controlled as the artist wishes.
What causes oil paint to dry so slowly?
The brand of paint used to make a painting has a lot to do with how long it will take the paint to dry. When purchasing paint, it is good to read the labels to determine its foundational ingredients. Specific paint brands and/or types are marketed toward attracting beginning painters.
This paint is often of a lower quality and its ingredients have different drying times than those of higher-quality paint.
Techniques of painting
If an artist uses heavier brushstrokes that cause deep textures, or when using specific techniques, such as impasto or fresco, the paint may not set up for as long as a week.
Each layer of paint needs to reach an acceptable level of dryness before the next layer is applied or flaking can occur. This is another case for having a specific drying area and method.
The environment plays a large role in the length of time that it takes for oil paint to dry. Things such as direct sunlight, moisture in the air, and humidity all have an effect on applying oil paint properly.
Oil paint is directly affected by the temperature of the room in which the painting is being created. When it is cold, the paint flows on easily and more smoothly. Some artists even choose to store their paintings in their freezers. When it is hot, the paint can seem to have a thicker, gummier consistency.
Storing oil paints in the freezer can make sure they retain their moisture and ideal level of viscosity. While not a good permanent solution, it is one sufficient enough to prevent wasting paint that is left outside the tube, and it enables the artist to continue working seamlessly within the next couple of days. Since oil paints can be expensive, this method can assure the paint won’t be wasted.
Considerations for color
Whether you store dried oil paintings in the light or dark can have a pronounced effect on the color retention of the paint. The changes can be subtle and barely noticeable, and in some cases will not change the artist’s vision of the work.
However, in other cases, depending on the quality of the paint, it can make a huge difference, so making a test piece to try out the various light levels in a storage area can be helpful.
How To Store Oil Paintings While Drying – Wrap up!
So let’s recap. When you want to know how to store oil paintings while drying you need to keep them in a room with a consistent temperature and humidity levels and store them by either hanging or on a drying rack of some kind that is away from dust, pet hair and winds that can blow debris onto the painted surface.
Ensure that the canvas is protected from accidents and try to back the backside of the canvas with a protective board.
