Oil paints how long to dry

This will ensure its safety and protection until the application of varnish or framing. We now understand the reasons behind the long drying period that comes with using oil-based paint. Now, let us explore some ways to improve on the process. By using additional oil-based paint mediums, it is possible to control the drying time by speeding it up or slowing it down. When implemented in combination with your oil-based paints, these products affect the fluidity, color, consistency, and drying time.

Artists often opt to utilize an oil medium together with a solvent. Each has its specific functional qualities, allowing ease of use when combined with your oil paints. We will now explore the various types of oil mediums on the market. When it comes to oil-based mediums, your oil paints are actually produced with some of these very oils, including safflower, poppyseed, linseed, and walnut. These natural mediums carry lower health risks with no toxic odor. These mediums are effective in techniques that need gloss or heavy strokes and textures.

Depending on which oil you use, you can either speed up or hinder the drying period when you add these mediums to your paint. These mediums excel when used to clean and maintain your brushes. The oils penetrate and condition the brush hairs, ensuring that they are flexible and free of paint. Using a solvent or thinner will shorten the drying times as they make the oil paint thinner. Techniques such as underpainting or creating washes are easily achievable using solvents.

You can dilute oil-based paint and also wash out color pigments. When cleaning your brushes, thinners and solvents can actually be extremely helpful. The chemical agents in these are highly effective in stripping the paint from brushes and cleaning any surface spills or paint marks. However, as it will deteriorate and spoil brush hairs, it is not advised to leave brushes soaking for extended periods in these chemicals. If you are sensitive to toxic smells, you can also make use of an odorless solvent product.

Free of any toxic chemical agents, these natural products are used as you would any chemical solvent. A citrus-based medium, for instance, contains high levels of citrus oils and water. The extreme acidity that occurs naturally in citrus fruit becomes a useful solvent to clean oil paint from brushes and other surfaces.

Spike lavender oil is another natural option, having been in use for centuries. This is an effective medium and has a tranquil scent too. When working with oil paints, Alkyd mediums are widely used for decreasing the drying period. The fast-acting resin they contain helps the paint set and harden in several hours. Generally, there are two types available: Liquin is of a lower viscosity and easier to work with, while the gel variant increases transparency and allows the paint to flow better.

Before painting begins, apply these to your canvas or other chosen substrate. A primer provides a porous surface for the effective adhesion of your oil paint, offering increased coverage and overall longevity of your canvas. Acrylic gesso is an excellent primer for working with oil paints. By using up to three coats and allowing the layers to dry fully between layers, you will have a more effective application and end result.

Another is to just set the thermostat to a higher temperature in your studio overnight, or during the day if you like it hot. When I used to do summer plein air events I would place a completed painting that was done on linen glued onto plywood in the back window of my car. However, I learned the hard way that you must be very careful with this process.

Sometimes the inside of my car got so hot that the linen began to separate from the plywood, and the plywood warped. Keep in mind that many painting panels are made with heat-activated glue. Some advocate using a heat gun on your oil painting. I have never tried this as I usually work wet on wet, but they claim it works.

If you use a heat gun, be sure to keep the setting under degrees fahrenheit as higher levels could result in yellowing or even cracking the paint. Move the gun slowly over the painting keeping it several inches away. Be sure the gun never touches the painting during this process. I've experimented with other heating methods that I will not mention for fear of inspiring you to accidentally set your house on fire.

Just be certain that if you use any kind of heating technique, don't go overboard and keep it safe. Better to wait a few days for paint to dry than to ruin your painting or burn your studio down.

Now we move away from environmental factors and onto technical and chemical methods to speed things up. The first being paint application. Thicker paint takes longer to dry. Oil paint drys through a process of oxidation which changes the paint's chemistry when it's exposed to air. The thicker the paint application, the longer this process takes since the entire mass of paint is not evenly exposed. There are numerous ways to thin oil paint. Solvents are probably the most widely used method, but you can also use different types of oils, dryers discussed below and thin paint application.

Bear in mind that if you thin your paint with oil, you will extend the drying time rather than shorten it. You can also thin the paint by just scrubbing it aggressively onto the canvas with a bristle brush without using any thinners AKA tube consistency. When painting with thin layers, always make sure the initial layer is the thinnest and has the least amount of oil content of any subsequent layers.

When painting in layers, I'll start by applying a very thin layer of paint with maybe just a touch of Gamsol Odorless Mineral Spirits see Resource Page for more info on Gamsol. Slightly thicker layers can be added with tube-consistent paint, leaving the thickest for last. The great thing about this approach is that the initial layer of thin paint will speed up the drying of the subsequent layers.

In many cases, it's the initial layer that takes the longest time to dry. Knowing this you can tone your canvas with maybe a warm earth tone like Transparent Red Oxide, let it dry, then start painting. If you apply thin layers of paint, many times they will be dry within a day or two depending on other variables which we will discuss below.

Notice I said subsequent because these products and others like them have a petroleum distillates base which acts like oil and therefore must follow the fat over lean principle described above. Dryers are used by adding a small amount into your paint mixtures prior to applying them onto the canvas. Thin layers of paint can start becoming tacky within an hour, while thick strokes of paint may still take one to several days to dry.

Gamblin makes several different versions of Galkyd with different rates of drying. These dryers also give the paint a glossy appearance.

Just be sure to use them as instructed since they generally do have some toxicity. I've found that Walnut Alkyd, made by M. Graham is probably the fastest of all when it comes to drying time. The nice thing about walnut alkyd is that it's non-toxic, boiled walnut oil.

Whenever I want something to be dry the next day, this will be my best bet. Failing to do so will leave you with hardened, unusable brushes. If this happens try Turpenoid Natural for cleaning and restoring your brushes. See more information on this and the mediums mentioned above on the Resources Page. Care to see more of my work?
