Why Use an Oil Paint Medium?
The most obvious question you may be seeking to answer is why do you even need to consider an oil paint medium? Well, an oil medium can alter the properties of the paint, making it more malleable and easier to manipulate. The oil paint that comes directly from the tube can be thick and difficult to work with. Different colors of the same brand may offer different viscosities in addition to drying times, and oil painting mediums can assist in giving the different colors the same qualities.
It is worth noting that most oil paints already have some sort of oil medium in them. In most cases, an oil binder is used to bind the pigment. That is all oil paint is – oil and pigment mixed. However, by introducing new mediums into the mix, you can take this already versatile art supply and make it your own.
Oil painting mediums recipes will create different outcomes, which is something that needs to be considered when it comes to finding the best medium for oil painting. Achievable effects including thinning or thickening the paint as well as influencing the drying time and texture. It can also change the finish from matte to gloss and even smooth out brush strokes.
By knowing which oil paint medium achieves which results, you can find the option best suited to your needs and create your own oil painting mediums recipes.
Using Different Types of Oil Painting Mediums
A painting medium allows artists to control oil-based paints more accurately by altering their characteristics. By knowing and understanding these oil mediums, different results can be achieved and take the piece of art to a whole new level. Using an oil paint medium requires some research and experimentation to achieve the specific result, but once you have the oil painting medium recipes sorted, the rest is smooth sailing.
Using a Solvent as an Oil Medium
When you use a solvent as an oil medium, you are able to give the oil-based paint a matte finish, increase the flow, thin out paint, increase transparency, and speed up the time it takes to dry. A solvent is usually used to clean painting gear and equipment like for cleaning oil painting brushes; however, many artists use it to facilitate their creativity and bring their imagination to life. When mixed with oil-based paint, the solvent then evaporates and leaves the binder and pigment to oxidize. This can then make the color appear brittle, dry, and dull.
It is recommended that you use a solvent only in the early stages of your painting, as this way it will not affect the end result.
Knowing how much to use will further assist as you work on your painting. Using too much of a solvent will result in a chalky effect that often cracks and distorts the art. When it comes to using a solvent for the first time, the general rule of thumb is to work on color blocking with pigment and solvent, working your way to a 1:2 oil-to-solvent ratio, and then gradually increasing the amount of oil with each additional layer.
To make your own oil medium, add linseed stand oil or cold-pressed linseed oil to your solvent of choice. The oil needs to be added to the solvent for this to work and not the solvent to the oil. Combine the mixture and let it sit for 48 hours to combine.
Turpentine, or turps, is the go-to choice for most artists as it is compatible with oil paint. When mixed, paint pigments will be perfectly dispersed and provide a beautiful, even finish. You need to buy artist-grade turpentine, however, as it contains fewer impurities. It is worth reminding you that turpentine is toxic when inhaled, so work in a well-ventilated space when using this oil medium.

Oil of Spike Lavender
Oil of spike lavender is a great alternative to turpentine as it mixes well with oil mediums and can break down and dissolve resins. This makes it the best product when it comes to thinning out thicker paints. What you may not know, however, is that this product is stronger than turpentine when it comes to solvents, which means that you can use less of it to thin out your paint. It can provide improved clarity, particle dispersion, as well as an adhesive for the different layers of paint. While this solvent is stronger than turpentine, it is less toxic, producing strong vapors with a more pleasant aroma.

Odorless mineral spirits are another artist staple when it comes to thinning paint and are a great option if you are looking for a solvent that does not have a toxic odor – although it is still a toxic substance. Unlike turpentine, mineral spirits are not as compatible with oil paints due to the abrasive nature of the substance. This medium is also waterier and dries a lot slower than turpentine.
We recommend spirits as a brush cleaner and not as an oil medium as it can weaken the paint and provide a less desirable finish.
Recommended Brand of Spirits: WEBER Odorless Turpenoid
This Weber product is almost as powerful a turpentine without the strong odor. It has all of the solvent-like qualities associated with turpentine without smell, and can easily be used to clean brushes or thin out oil paints.
Using an Oil as an Oil Paint Medium
Now that we have taken a look at the solvent aspect of oil paint mediums, you are now ready to look at the next part, the oils. When you decide to add oil, you are more than likely looking to thicken paint, increase paint flow and transparency, and slow down the drying time. It is worth noting that not all oils can be used when painting with oil-based paint.
This because these oils are siccative and have gone through a process known as polymerization, which allows the oil to combine with air and create a solid layer. This oxidizing ability is why many people refer to these mediums as drying oils.
Tung, perilla, and soybean oils are also common mediums, although they are not as user-friendly as linseed, walnut, poppy seed, and safflower oil.
This oil comes from the ripe, dry flax plant. This means that it is sometimes sold as flaxseed oil or flax oil. This oil is incredibly durable, which is why it is often used to create oil mediums. It provides a glossy finish to paints, slows down the time they take to dry, and reduces the paint’s viscosity. Another favorable quality of this oil is its linoleic and linolenic acid, which help to produce a durable, long-lasting paint film, although they can result in yellowing of the paint with age. When it comes to selecting an oil, look for an oil with linolenic acid, as it builds a strong film.

When it comes to oil mediums, Winsor and Newton have a product range that meets all needs. This prodyct has all of the properties you look for in linseed oil and produces the long-lasting, glossy finish that artists seek to achieve when using this oil medium.
Cold-Pressed Linseed Oil
Cold-pressed linseed oil can be used with oil of spike lavender to create a lean medium if that is what you are looking to achieve. This variety of linseed oil creates a harder, shinier finish, and also takes less time to dry. This high-quality oil is used as a binder in many oil paints and is often mixed with professional paints made using rich, pure pigments. The acid content makes it a great choice for a binder and coats pigments a lot more effectively than other oils.
Recommended Brand of Cold-Pressed Linseed Oil: DANIEL SMITH
As one of the most innovative paint manufacturers, it should come as no surprise that Daniel Smith offers a high-quality cold-pressed linseed oil. This product is fantastic for extending the use of your paint while improving flow, gloss, and transparency.
Linseed Stand Oil
Linseed stand oil, or linseed bodied oil, is also derived from the flax plant. It is different in that it is made from refined linseed oil that has been heated to high temperatures in a vacuum-sealed chamber. It is more concentrated as a result and has a thicker consistency, which stretches out your paint and allows you to do more with a lot less. It is also ideal for glazing and will leave a glossy finish.
Another great benefit that comes with this oil is that does not yellow with age like other linseed oils, and it is also not as easily absorbed into the layer, which makes the paint appear dull.
Recommended Brand of Linseed Stand Oil: WINSOR & NEWTON
Winsor and Newton are big names when it comes to painting. Their linseed stand oil provides a durable, smooth finish while slowing down the drying time of your oil paints. It also reduces the risk of brush marks and helps make the paint and color last longer.
Safflower oil only contains linoleic acid and, as a result, is seen as a weaker binder. As an oil medium, this oil reduces viscosity while increasing flow. Paint is, therefore, more easily spread. Safflower oil also produces a film that does not wrinkle with age; however, it is weaker than other oils. It is also slow drying to the point that it never completely dries or cures. When exposed to excessively hot temperatures, the paint has been known to melt.
Safflower oil is not often recommended as an oil paint medium, although, when used sparingly, it can provide great results. One such example is applying thin layers to your painting with the intention of mixing it with lighter colors. As with most mediums, there are ways to even out the unwanted and negative properties. For example, to counteract the weaker film layer, you can always apply a varnish to seal the paint layer.
Recommended Brand of Safflower Oil: MONT MARTE Safflower Oil
Mont Marte’s safflower oil is suitable for all colors, including white and pale hues, as the oil does not cause the paint to yellow. It can add gloss to your painting while slowing down the drying time, resulting in more time to fine-tune your masterpiece.
