Oil Painting Mediums – Choosing the Best Medium for Oil Painting

When it comes to painting with oil-based paint, there are so many oil mediums that can be added to the mixture. This is done to change the finish, consistency, drying time, and transparency of the paint. Additionally, it can also be used to stretch out the use of your paint by making it last longer. An oil medium can come in many different forms and, as a result, can and will produce different effects. This can make it tough to determine the best medium for oil painting from the get-go, but not to worry! When it comes to oil mediums, we have everything you need to make an informed decision.



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.

Oil Medium

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.

Oil Painting Mediums Recipes



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.

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.

Oil Paint Medium

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.


Linseed 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.


Recommended Brand of Linseed Oil: WINSOR & NEWTON Linseed Oil

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.

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.

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.

  • Tough, durable film
  • Reduced brush marks

  • Lid is difficult to open


Safflower Oil

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.

What Is a Paint Medium

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.

Poppy Oil

Poppyseed oil is a clear oil that will not yellow with age or affect the color of your painting in the long term. Monet used this oil as a binder when painting his Water Lilies series, which explains why his artworks have been able to maintain their bold, vibrant colors. This drying oil is one of the slowest to dry while improving the flow and gloss finish of your work. It also lacks linolenic acid, which makes the paint and its film softer. You can rectify this by adding linseed oil to the mix.


Recommended Brand of Poppy Seed Oil: WINSOR & NEWTON Poppy Oil

As you may have noticed, Winsor and Newton lead the pack when it comes to their product range of oil painting mediums. Their drying poppy oil dries quickly and will not yellow over time, making it perfect for use with light colors.

Walnut Oil

Another great alternative to linseed is walnut oil. It is more durable and flexible than safflower and poppyseed oil and will not yellow like linseed oil. This oil can be mixed into paint the same way you would other oils and can even be used to clean brushes if you are looking to keep your workspace free from solvents. Walnut oils are incredibly glossy, add depth of color, and are hard-wearing. They are also able to slow down the drying time and improve paint flow.

Painting with Oil Mediums

We recommend storing this oil in the fridge as warm temperatures and exposure to sunlight can cause the oil to go rancid. While you should be aware of the fact that all oils will go rancid as a result of air exposure, nut-based oils will go rancid if the bottle is not properly stored or sealed. This oil can also be used in oiling out a painting, which is when you apply a thin layer of oil to a dry area of the painting to restore the color and its vibrancy.


Recommended Brand of Walnut Oil: M GRAHAM Walnut Oil

Using a Cold Wax as an Oil Paint Medium

If you are looking to thicken your paint to add volume, body, texture and provide a matte finish with a  speedy drying time, then we recommend using cold wax. The thick texture of this oil medium is unique and even has a style of painting dedicated to its use. Cold wax painting is a style that involves textures, magnificent brush strokes, and beautiful matte finishes. If you do not want a matte finish but want the textured benefits, try adding alkyd to the mix.

Cold wax adds a whole new dimension to paintings and allows you to build layers to add structure. It can also add increased transparency and luminosity to your work.

There are so many ways to add cold wax to oil paints in order to create a wide range of effects. In most cases, the medium is a mix of solvents, resin, beeswax, and even linseed oil. This is because the solvent evaporates while the wax hardens to create a lasting impression.

Using an Alkyd Resin as an Oil Paint Medium

To add body to your painting while speeding up the drying time and adding a glossy finish, we recommend an alkyd resin. This is a synthetic resin that consists of a polymerized plant-based oil and a slow-evaporating, odorless solvent. When mixed with oil, it should dry within a day. This is the ideal medium for the fast painter that does not want to wait weeks between layers. Alkyds can also help stretch your paint without becoming too transparent or runny.

Frequently Asked Questions


What Is the Most Commonly Used Medium?

Without a doubt, linseed oil is the artist’s standard. This traditional oil paint medium increases the drying time while thinning out the paint. This is beneficial for artists looking to spend more time on their creations while having the freedom to make changes.


What Makes Oil Paint Better Than Acrylic Paint?

One of the greatest benefits offered by oil paints is their delayed drying time. Unlike acrylics, it takes longer for the oil paint to dry, which means that artists have more time to work on their colors and textures. This also means that you do not need to worry about the paint on your palette drying out before you have time to use it all. You use less paint in the process, waste less paint, and save money all in one go. Of course, this depends on your needs and what you are working on. If you would prefer paint that dries faster, then acrylic should be on your list. It is worth noting that you can use acrylic paints for the basis of your painting before adding layers of oil paint.

We have a separate blog post about oil vs acrylic paints.


What Do I Need for Oil Painting?

When it comes to painting with oil, there are a few things that should be in your setup. The first and most obvious being the surface or canvas, paint, and paintbrushes. Next, you will want to buy some oil paint mediums to assist you along the way. In addition to this, we recommend a jar for cleaning your brushes, rags for cleaning up, a palette for your paint, pencils for drawing, and clothes that you do not mind ruining in the process.


Why Do I Need an Oil Medium?

Some may argue that paint is in its best possible form and condition when it comes directly from the tube. Most high-quality paint manufacturers have not created their products to be influenced by mediums, so when you are using these more expensive, premium brands, a medium will more than likely not be necessary. However, lower-grade paints may require assistance in giving the result that you are looking for. Of course, at the end of the day, it is about what you want to achieve with your art and finding the best way to do so.


What Is the Best Method of Incorporating a Medium?

Most art teachers will teach their students to paint first and then add a medium to the mix to thin it out or smooth the appearance if necessary. When it comes to oil mediums, you need to be sure of your intent and be cautious when adding them to your paint. Rather add bit by bit until you get the desired results. Remember, oil paints are supposed to be stable while providing the freedom to alter them at any given time. The general rule of thumb is not to exceed 50 percent oil capacity when it comes to your paint mixture.


What Is the Benefit of Using an Alkyd?

An alkyd allows the paint to dry a lot faster due to the fact that it contains a solvent, which in most cases, is turpentine. As the solvent evaporates, the paint will begin to dry. Depending on the paint thickness, it should be able to dry overnight. This means that you can work for a few days in a row instead of waiting weeks between applications.


How Can You Seal Oil Paint?

In addition to being fast-drying, an alkyd can also be used to seal paint by creating an isolating layer. Once you have finished your work, you can apply a layer of alkyd to it. This glaze can be added to your art without the risk of lifting the paint. For the best results, the paint needs to dry completely and then have the alkyd applied. Once dried, you can paint over with a glaze or opaque paints. You can reseal it at any time to lock in the layers.


What Is the Best Medium?

This is a difficult one. The reason there are so many mediums available is that they offer different results and are used for different purposes. In addition to this, you can create your own oil medium recipe to ensure that you achieve the result you are looking for. This all requires time, patience, and creativity to figure out. The first thing to do in it all, however, is to decide what it is you want to achieve. This will guide the way in terms of what medium to try and how to further enhance your paint.
