When it comes to painting, there’s a decent amount of debate as to whether you should use oil or acrylic paint. Both have their pros and cons and while both are significantly different, they can be used to produce incredibly similar paintings. So the question “Can I mix oil and acrylic paint?” is legitimate as we want to have the best features of 2 paints.
You cannot mix acrylic paint with traditional oil paint. However, you can mix acrylics with water-based oils. Oils and acrylics have different compositions and cannot be properly mixed as oil doesn’t mix well with water.
Whether you’re looking to learn how to mix oil paints or want to get advice on your current mix, this article is a great resource! Here’s what you need to know about mixing oil and acrylic paint.

Can you mix oil and acrylic paint?
You should never mix oil and acrylic paint even though you technically can do it. Although oils and acrylics are the most popular on the market, they are very different.
The bases determine whether you can mix any two paints. Water mixes with water, oils with oils, etc. Oil paint is oil-based and acrylic paint is regarded as water-based. If you mix them, the paint will separate because water is denser than oil, forming layers of acrylic and oil paint inside the container.
However, you can potentially mix acrylic with water-based oil paint!
Difference between oil and acrylic paint:
- drying times, acrylic dry in 30 min., oil can take days
- painting techniques
- thinners, and mediums to use, we use solvents like turpentine to prepare oils for painting, but acrylics can be painted directly or thinned with just water. Oil paint cannot be thinned with water.
- texture: acrylic dries to a plastic-y feel and can have texture, but oils are smooth
- adhesion: acrylic cannot stick to oils, but oils can stick to acrylics.
so even if you do mix oil and paint, you won’t be able to achieve your painting goals and the new mix won’t be archival or any durable!
No matter how much you mix or swirl the paints together, oil is hydrophobic, so it won’t dissolve in water.
However, technically, you will be able to mix two paint into one new color, here I did it:
What happens if I accidentally mixed oil and acrylic paint?
If you’re a beginning painter, you may accidentally mix oil and acrylic paint. And visually nothing will seem to be wrong!
So what happens if you accidentally mix oil and acrylic paint? Oil and acrylic paint won’t fully merge if you mix the two, therefore what you’ll get is a dispersion of the two paints inside a container.
I tried mixing white oil paint with magenta acrylic, and yellow oil with blue acrylic. Both times it took quite a lot of time to really mix it, and it still wasn’t mixed 100%. The texture and drying time was more close to oil paints. After 24 hrs it was still not fully dried, but already water-resistant.
At the same time, the next mixed color wasn’t durable at all – I could just scrape it with my nail from the paper! It didn’t stick to the surface at all! The finish was satin and soft to the touch though. Check the video above to see the results.
You may still be able to put it on the canvas. But acrylics dry fast, but oils do not. Mixing them will result in uneven drying within a layer of paint, and ultimately cracks.
The acrylic paint will flake off since it won’t be able to adhere to the oil paint.
That will be a lesson learned for you, but if you accidentally mix the two, do not panic here’s what you’re going to do:
- If you accidentally mix it on a canvas, just clean the paint away with a paper towel and then wash it with soap and water and dry it.
- If you by accident mixed oil and acrylic in the container, try to thin the paint and see if it will be usable. If not, I’m afraid you will have to discard it.
Can you mix oil-based paint with water-based paint in general?
As a general rule, any oil is hydrophobic and oil-based paints won’t mix with any water-based paints.
You can, however, use two different mediums in a mixed media painting: water-based paint first, as it needs to adhere well to the canvas, and once it dries, you can paint over a layer of oil-based paint.
Just a quick reminder, water-based paints are: poster paint, tempera, gouache, acrylics, watercolor.
Can you mix oil pastels and acrylic paint?
No. Acrylic paint and standard oil pastels should not be combined. Oils and acrylics don’t mix well since acrylics are water-based. Oil pastel has a non-drying oil-based binder, and it is never completely dry.
Due to both of these issues, the acrylic paint will not adhere properly to the oil pastels and may eventually peel off. It is preferable to layer oil pastels over acrylics when combining the two media.
For the best effects and to avoid cracking, use oil pastels over the dried acrylic paints if you want to use them together, or use water-soluble oil pastels like crayons and acrylic paint together.
You might try one of the several acrylic paint additives that can change the viscosity, clarity, and handling of the paint while layering oil pastels over acrylic paint.
Can you mix acrylic paint with other water-based paints?
Yes, acrylic paints are water-based, so you can mix them with other water-based paints like latex paint or watercolors.
Using acrylic and watercolor in one painting, apply acrylic paint over watercolor.
While acrylic paints from various brands can be mixed in theory, the results frequently have an impact beyond the paint’s color. Keep in mind that each brand may have a distinct composition so you can end up messing with paint ingredients.
A good stir and a test are advised because it wasn’t intended to be used with water-based paint like acrylic.
Can you mix oil-based and latex paint together?
Latex paint is water-based and will not mix with oil-based paint.
If you are doing some renovation and your walls were painted with oil-based paint earlier, you can apply latex house paint over them.
The new paint will expand and contract at a different rate than the existing layer if you apply oil paint over latex, which will cause the new paint to break. Without any prior preparation, latex will not adhere effectively to an oil-based layer, and it may also easily break or peel.
How to use oil and acrylic paint on the same painting?
Even though we can’t mix oil and acrylic paint, we can still use them in the same painting.
Priming a canvas for oil and acrylic is the same – you should apply a coat or 2 of gesso or buy a pre-primed canvas.
Because acrylics dry so quickly, some artists begin their paintings with acrylics as an underpainting and then finish them in oils.
Before beginning with the oil paint, make sure the acrylic paint has dried completely – all the way through, not just a touch dry on the surface. I would leave it overnight at least.
Be aware that while acrylic works well as an underpainting for oil paintings, it should never be applied directly over an oil painting. Oil paint dries smoothly, but acrylics cannot stick to oily surfaces and might flake away as they dry. Additionally, oils dry more slowly than acrylics, which may eventually lead the acrylic paint to break and crack.

How do I turn acrylic paint into oil paint?
It’s common knowledge that oil paints merge easily. You can blend them for as long as you like because they dry slowly. It is possible to eliminate all traces of brush strokes. A smooth gradient is produced when two colors are smoothly blended. This is helpful when painting the fluid color shifts that occur in the sky and bodies of water.
All these factors make people working with fast-drying acrylics want them to blend as easily as oils.
You cannot change the paint composition, but you can use slow-drying acrylics or mix a retarder into your preferred brand of acrylic paint to blend acrylics like oils and have more working time (up to 1 hour).
By incorporating acrylic gel into the paint, acrylics may be made to be as glossy and thick as oils. Accurate color mixing is a talent that aids in achieving the oil painting effect with acrylics.
Can you paint oil over acrylic or acrylic over oil?
You can paint oils over acrylics, but you cannot layer acrylic on top of oil paint as it won’t stick. Oil paint is more flexible than acrylic, so it can be worked on and reworked, which allows one to work on the canvas while a portion is drying.
Acrylic paint dries to a hard finish, and cannot be reworked with water or any medium once dried. Once the acrylic is dry, you can use oil paints to carefully cover the acrylic paint once it has dried.
Even if you will seal acrylic over oil it won’t be archival and will not last longer than a couple of weeks. Yet, you can also apply an oil-based sealer over acrylics if they are non-yellowing.
So If I can’t mix, what should I use, oil or acrylics?
This is a question with no perfect answer. You can achieve amazing results with both acrylics and oils.
I am impatient, so for me, acrylic paint is the best: easy to mix, apply, clean up, has no odor, and dries in minutes. I used oils too, and loved it, it is a sort of meditation and feels very professional lol 🙂
Acrylic paint is cheaper, I believe, and is more beginner-friendly. I also don’t really like to work with solvent to thin oil as some of them smell strong.
Frequently Asked Questions
Can you mix baby oil with acrylic paint?
Never use non-drying baby oils with acrylic paint! Mineral oil, which is what baby oil is, doesn’t dry. It won’t dry if even the tiniest quantity gets into your paint. Oil won’t let acrylic paint stick to any surface and dry, it will break the paint composition and you will simply ruin the paint.
You can use it to wash your hands because it works well to remove oil paint and is gentle on the skin.
Do not even dare to use it to wash your brushes, though. It would be horrible if even a little of it migrated to the paint. If you clean your brushes with mineral or baby oil, make sure to wash them thoroughly with soap and warm water to get rid of all the oil. It couldn’t be used as a medium for painting.
Can you mix water-based oil and acrylic paint?
Wow! There is water-based oil paint on the market that was designed to be able to mix with water! Yes, you can mix water-based oils and acrylic paints. If the pigments are compatible, they will react with each other to create a new color.
But the problem may be with drying – oil still tends to dry very slow compared to quick-drying.
Additionally, it’s likely that you’ll combine varying amounts of acrylic and oil paint during the painting. The acrylic and oil paints in the same painting are used in differing amounts and dry at various rates. Water soluble oil paints can often be blended with either, but you should view this as an experimental technique because they span the gap between oil and acrylic paints.
Can you mix acrylic paint with olive oil?
No, it is not a good idea to mix olive oil with acrylic paint. Acrylics are water-based paints, thus any product containing oils won’t mix well with them. Olive oil is a very unreliable media because it does not cure like acrylic paint and is not permanent.
Olive oil cannot be used for painting and cannot be regarded as an archival art medium. Future adhesion problems could be a result of the oils. The olive oil could potentially turn rancid before it dries.
It will always run into a painter’s mind the question “Can you mix oil and acrylic paint?” For you to have a clear answer, it is definitely a no. The simple reason is that oil and water do not mix. Oil and acrylic paint are two different types of paint that serve different purposes. Oil paint is known for its ability to create rich, deep colors, while acrylic paint dries quickly and is ideal for painting in layers.
If you try to mix the two types of paint together, you will end up with a mess. The best way to use both oil and acrylic paint is to create separate paintings or to use one type of paint for the background and the other type of paint for the foreground. We hope that this article enlightens and helps you with your oil and acrylic paint problems.
