What Is The Difference Between Oil And Acrylic Paint

What is the difference betwixt Oils vs Acrylic Paints?

Practise you want to learn to pigment but don't know where to start?

Get excited virtually all the paintings yous are going to create but don't know which types of paints to begin with?

To understand the pros and cons of oils vs acrylics yous demand to ask yourself a few uncomplicated questions to decide which medium is best for you…

Please note: The comparison below is for standard acrylics and oil paints, not taking into account quick-drying oils 'Alkyds Oils' or 'Open up Acrylics' (ho-hum drying acrylics) or 'Water-mixable Oils' (traditional oils than tin can be cleaned up with water)

1. Practise you piece of work quickly or slowly?

Acrylic Pros: Yous tin can paint on annihilation.
This is one of the key things that brand acrylics a smashing medium to start with when beginning to learn to paint. To exist able to gear up chop-chop, offset painting on anything is brilliant. Paper, card, canvas board, whatever y'all have to hand.

Acrylic Cons: They dry chop-chop, I hateful really quickly.
You want to do some painting, so you book in a little me time. You've got a canvas ready, you've prepared your ground and at present you lot're ready to paint.
All is quiet and at peace with the world. You lot carefully squeeze out your paintings, being conscientious non to utilise too much, and and so what happens?

The phone rings.

Wrong number.

In this short amount of time, the first blob of paint you'd squeezed out will at present exist dry, solid, unable to shift. And then you scrape it off, squeeze out some more, ready to become and…

A knock at the door.

You put down your brushes, come back ten minutes later on and everything has dried! Not quite the tranquil painting experience you lot had imagined.

The solution?

• Squeeze out more paint
• Add together a retarder to keep the acrylics wet for longer (no more than than 15% or the paint goes funny)
• Use a stay moisture palette to keep the paints moist. Run into my video on How to ready a stay wet palette.

Oil Pros: Longer working time.
Because oil paints stay wet for a lot longer than acrylics, it gives y'all the flexibility to start a painting then come dorsum to it the next 24-hour interval and continue straight where yous left off. The paint on the palette will still be wet and pliable; the colours on your canvas tin still exist composite together.

Oil Cons: Preparation is central
Due to the oil in oil paints (usually linseed oil) its all-time to on work on a prepared canvas or lath. If you are going to prepare the surface of the canvas yourself the training time is longer. You could, of course, buy a pre-primed canvas and get going straight abroad. (encounter: preparing a surface for painting)

2. Practise you like subtle blends or hard lines?

Acrylic Pros: A Crisp edge
The crisp edges that tin can be achieved with acrylics can be hugely benign if you paint with a more graphic composition. You tin can mask out areas, work over them chop-chop, and easily embrace a hard shape with thicker paint. You can mix clean, bright colours very easily.

Michael Craig Martin

Acrylics Cons: Achieving a smooth blend
Blending with acrylics can be frustrating due to the speed of the drying time. Especially if you are working on a large-calibration it tin exist practically impossible to work the canvas equally a whole to bring it all to the same stop together.

This is for a size of say 6ft x 4ft. If yous are working smaller than this you can create some lovely blends.

You can achieve smooth blends with acrylics you take to work quickly. You lot tin can add a medium to the pigment to help proceed the working time open up for longer. Either employ soft gel gloss, retarder (slows down drying time) or my preferred choice, glazing liquid gloss.

Pro tip: I use the glazing liquid gloss even if I don't need a gloss terminate. This is because the matting agent used in the matt glazing liquid is white when wet, it dries pretty articulate but I have found it can sometimes exit the blacks looking milky)

Oil Pros: smooth blending
Oil paints are king of the ring when blending colours together. Because of the irksome drying nature of oil paints they tin be fantastic for creating subtle blends.

Working wet-into-moisture is the sure-fire way to become a smoothen transition in your painting. This is especially true for portrait painting when the subtle shading of the face tin can need constant revisiting and tweaking. You lot tin can also add slower drying oils to your paints to create surfaces that can stay moisture for weeks.

Oil Cons: Trying to create a crisp edge without it affecting the underlying colours with oils means yous have to wait until the side by side day, or touch dry otherwise your brushstroke will pull and mix with the paint underneath it. It is very easy to mix 'dirty colours' when starting with oils due to everything staying wet and the colours mixing together on the canvas.

Solution: Experience teaches you to work cleanly.

3. Colour shift

Acrylic Pros: They are lightfast
With projected laboratory tests acrylics won't fade in time, the colours will look the aforementioned now as they will in 200 years. The binder in oil paint – oil, goes yellow over time, this causes the subtle glow on old master paintings with acrylics they are colourfast, the folder – acrylic polymer doesn't xanthous over time.

Pro tip: The most likely cause of fading is using pigments that are not lightfast, this is true of oils and acrylics.

Acrylic Cons: They modify color when they dry out.
The binder used in acrylics is ordinarily white but dries articulate (the recent folder in Winsor & Newton Artists' Acrylics is clear, but I feel still has a slight colour shift) This means it seems lighter on the sheet when you outset put in on and then dries darker as the white folder turns articulate.

This becomes really articulate when painting portraits. You remember you've cracked the precise color, plough around and the colour has changed. With practise, you tin acquire to approximate to shift but it can be disconcerting when you're first beginning.

If you add more acrylic polymers to the paint, in the form of mediums (quick-dry mediums, menstruation release medium) the colour shift will be even greater.

If you use student quality paints that take extra fillers added, which are often white, the colour shift volition be more than pronounced.

Oil Pros: No immediate colour shift.
Initially, oils stay the same colour when painted on a sheet. Still, once the color dries information technology tin can announced to change if the oil from the paint 'sinks in' to the canvas.

This tin can lead to some areas being sleeky (still accept the oil in) and others staying matt (oil has soaked into the underlayer) to produce a deader colour. To overcome this, you take to "oil out' the expanse of the painting you lot are working on. A paint surface tin appear dull and is usually caused by also little oil in the paint film due to the absorption into the basis layer (or overuse of thinners such as turpentine)

Pro tip: In classical painting, you build an oil painting up in layers and one of these layers is called the 'dead colouring layer' It is painted using oil pigment thinned with turpentine on an absorbent gesso footing, this soaks up the oil, speeds the drying time and gives a local color to the painting.

Oil Cons: Yellowing
Oil paints will have a slight yellow tinge to them due to the color of the oil (think of olive oil) As oil dries over fourth dimension through the process of oxidation additional yellowing takes identify. This varies in degree depending on the folder used in the paint.

"Yellowing must therefore be considered every bit an unavoidable feature of drying oils and this must be kept in mind past users."
Professors Mallegol, University Blaise Pascal in French republic.

four. Practice you like working with thick paint or thin layers?

Acrylic Pros: Acrylics are flexible.
If you like the idea of using a palette knife and creating thick, impasto paintings, acrylics could be the pick for you. You tin pigment thickly, build it up and the pigment volition dry. If y'all effort to achieve the same with oils the outer surface volition dry to the touch but the inner paint will notwithstanding be wet.

You tin besides work very thinly with transparent glazes or very thickly with a mountain of pigment but the bodily surface quality of the acrylic remains flexible, this means your painting won't crack over time. Thin coats of acrylic paint can be used to requite a watercolour await to a picture.

Pro tip: Acrylics can crack but usually only in extremely cold temperatures.

Oil Pros: Long drying times
If you have plenty of fourth dimension fix aside for your painting, oils tin can be fantastic. You can work with thick paint, wait a couple of days for that paint to dry then add sparse glazes to create luminosity in your piece of work.

Oil Cons: To work with thick paint you need to take into account the drying time of oils. Each particular pigment needs a different amount of oil mixed with it resulting in different drying fourth dimension, eastward.1000: Earth colours such as Burnt Umber is a rapid dryer whereas Ivory blackness takes much longer to dry.

The solution: Add a siccative to the paint. A siccative is a medium that helps to speed upwardly the drying process in oil paints. Traditionally this was a cobalt drier, more than recently, Liquin past Winsor & Newton is a synthetic medium that can advance the drying time of the oil paint by near l% .

Pro tip: Its best ever to work in a well-ventilated area when using liquin (Wikipedia link) as some people can take sensitivities to the Petroleum Distillates used in the product. Liquin Original Safety Sheet

5. Do yous work in a small infinite?

Acrylic Pros: Acrylics can exist a cracking alternative to oils if you lot're working in a confined space. You just need access to h2o and they accept a very low odor in comparison to traditional oil painting thinners.
Pro tip: Take ventilation is yet brash every bit some acrylics brands incorporate trace elements of ammonia, (meet Princeton University wellness & prophylactic) this varies from brand to brand.

Oil Cons: The scent of turpentine
If you offset painting with oils in a confined space the fumes from the thinners can overwhelm you, turpentine and white spirit can be really strong. White spirit can too be an irritant to the skin and turpentine rags tin can spontaneously combust!
I work with odourless mineral spirits or 'Zest It' (a thinner made from citrus ) that take a very petty scent compared to turpentine.

There are many new solvent-free gels now coming to market, such equally Gamblin's Solvent-free Gel. These offering a mode of diluting the oil paint without using traditional solvents. Yous can likewise clean your brushes with walnut oil (Tater'south lather in the Us gets good reviews).

Pro tip: The odourless mineral spirit does not cut through the oil as well every bit pure creative person turpentine and if you are using Dammar varnish in your mixes tin cause problems.

Conclusion

Phew!

Okay, there's a lot to take in merely one time you become to grips with which pigment is best for your fashion, oils vs acrylics, then you can merely go on and create masterpieces.
