Acrylic vs Oil Paint vs Watercolour: Which Is Best for Beginners?
Acrylic, oil and watercolour are three popular painting media, but they reward very different ways of working. Acrylic dries quickly and is forgiving, oil stays workable for longer, and watercolour creates transparent washes that are difficult to cover once dry.
For many beginners, acrylic is a straightforward place to start. It cleans up with water while wet, lets you build layers quickly and allows many mistakes to be painted over once dry. Choose oil if you value long blending time and rich, gradual colour transitions. Choose watercolour if portability and transparent, luminous washes matter most.
This guide compares acrylic vs oil paint vs watercolour by drying time, setup, cleanup, difficulty and finish. It also explains why acrylic is used in our paint by numbers kits.
Acrylic vs Oil Paint vs Watercolour at a Glance
| Property | Oil paint | Acrylic paint | Watercolour |
|---|---|---|---|
| Drying time | Usually days; thick layers can take much longer | Often minutes to hours | Often a few minutes |
| Beginner experience | Long working time, but more materials and technique to learn | A forgiving all-round starting point | Simple setup, but corrections can be difficult |
| Typical setup | More materials and preparation | Simple starter setup | Simple, compact setup |
| Cleanup | Depends on the system; traditional oils may involve solvents | Water while the paint is wet | Water |
| Typical look | Rich colour, smooth blending and visible texture | Versatile, from thin washes to bold opaque layers | Transparent, soft and luminous washes |
| Correcting mistakes | Long wet working time allows adjustment | Usually straightforward once the layer is dry | Limited because the paint remains transparent |
| Common surface | Prepared canvas or panel | Canvas, paper, wood and many prepared surfaces | Watercolour paper |
| Safety and ventilation | Check paint, medium and solvent labels; ventilate when required | Check the exact product label and clean up before it dries | Check the exact product label; do not assume every pigment has the same safety profile |
Drying times are ranges rather than promises. Pigment, paint thickness, humidity, temperature, surface and added mediums all affect how quickly a layer sets.
Oil Paint: Slow Working Time and Rich Blending
Oil paint is made by dispersing pigment in a drying oil, commonly linseed oil. The binder gives the paint its characteristic smooth, buttery handling and allows gradual blending on the painting surface.
How Long Does Oil Paint Take to Dry?
Oil paint dries through oxidation rather than simple water evaporation. A thin film may become touch-dry in several days, while certain pigments, thick applications and cool conditions can extend that time considerably. A painting can feel dry at the surface long before the full paint film has cured.
The slow pace is useful when you want to soften edges, mix transitions directly on the canvas or return to an area during the same session. It is less convenient when you want to add several separate layers quickly.
Working With Oil Paint
Traditional oil painting can involve mediums and solvents, so read every product label and use the ventilation and disposal method the manufacturer specifies. Solvent-free approaches and water-mixable oil colours are also available; oil painting does not have to mean using turpentine.
Layered oil painting also requires some understanding of paint-film structure. The familiar “fat over lean” principle helps later layers remain more flexible than the layers beneath them. For a complete beginner, this adds more technique and material choices than acrylic usually requires.
Oil Paint Pros and Cons
- Pro: long working time for blending and adjustments
- Pro: rich colour and a wide range of transparent and textured techniques
- Pro: can produce a durable paint film when materials are used and cared for correctly
- Con: slow drying makes fast multi-layer sessions difficult
- Con: a traditional setup can cost more and involve additional materials
- Con: solvents and some pigments require label-led handling and ventilation
Acrylic Paint: The Forgiving All-Rounder
Acrylic paint contains pigment in an acrylic polymer emulsion. It is water-thinnable while wet, then forms a water-resistant paint film as it dries. That combination makes acrylic practical for home painting and especially approachable for beginners.
How Long Does Acrylic Paint Take to Dry?
A thin acrylic layer can begin setting within minutes, although a thicker layer takes longer. Warm, dry airflow speeds the process; cool or humid conditions slow it. Retarder and open acrylic products can extend working time when you want more blending.
Fast drying makes it possible to add several layers in one session. The trade-off is that paint can dry on a palette or brush before you expect it to. Keep brushes damp while working, rinse them promptly and see our guide on how to thin acrylic paint correctly if the paint feels too thick.
Working With Acrylic Paint
Acrylic can be used in thin washes, flat graphic shapes or thicker textured marks. It adheres to many surfaces when they are clean and prepared for the product being used. Once a layer has dried, you can usually cover it with another opaque layer, which makes experiments less intimidating.
Individual formulations and pigments differ. “Water-based” does not mean that every acrylic product is automatically harmless in every situation, so follow the label, avoid ingestion and use products intended for the painter and setting in question.

Acrylic Paint Pros and Cons
- Pro: fast layering and easy water cleanup while wet
- Pro: affordable starter sets are widely available
- Pro: works with many techniques and prepared surfaces
- Pro: mistakes can often be painted over after drying
- Con: short open time can make slow blending difficult
- Con: dried acrylic is difficult to remove from brushes and clothing
- Con: some colours shift slightly as the wet film becomes clear and dry
Watercolour: Transparent Colour and Portability
Watercolour — spelled watercolor in American English — usually combines pigment with a water-soluble binder such as gum arabic. It is sold in dry pans and moist tube colour. Dry pan colour can normally be reactivated with water, which makes a small palette convenient for travel and sketching.
How Long Does Watercolour Take to Dry?
A watercolour wash often dries within minutes, but the amount of water, paper, room conditions and painting technique all matter. Timing is part of the medium: wet-on-wet colour spreads softly, while colour placed on dry paper creates a harder edge.
Working With Watercolour
Watercolour is transparent, so painters usually work from light to dark and reserve the white paper for the brightest areas. Dark passages are built through controlled washes. Some colour can be lifted with clean water, but a light mistake cannot always be hidden beneath an opaque layer as it can with acrylic.
This makes watercolour easy to carry but not necessarily easy to master. A compact pan set, brush and suitable paper may be all you need to begin, yet water control and planning take practice.
Watercolour Pros and Cons
- Pro: distinctive transparent and luminous results
- Pro: compact, clean and highly portable setup
- Pro: dry pan colour can usually be reactivated
- Con: light-over-dark corrections are limited
- Con: unsuitable paper can buckle or pill
- Con: finished work needs protection from moisture and prolonged strong light
Which Paint Is Best for You?
Choose Acrylic if You Are a Complete Beginner
Acrylic is the most practical starting point for many people. The setup is manageable, layers dry quickly and a dry mistake can often be covered. It teaches brush control, colour mixing and layering without the waiting time of oils or the transparency constraints of watercolour.
Choose Oil if You Enjoy Slow, Deliberate Work
Oil suits painters who value extended blending time and do not mind planning around drying. It is a good match when the process itself — adjusting edges, transitions and layers gradually — is part of the appeal.
Choose Watercolour for Travel and Transparent Washes
Watercolour is ideal when you want a compact kit, quick studies and a light-filled transparent result. Expect to spend time learning water control and planning around the untouched white of the paper.
Still Undecided? Start With Acrylic
Acrylic gives you a broad and forgiving introduction. Once you know whether you enjoy fast layers, slow blending or transparent washes, you can move towards oil or watercolour with a clearer sense of what you want from the medium.
What Type of Paint Is Used in Paint by Numbers Kits?
Our paint by numbers kits use pre-mixed, water-based acrylic paints. Acrylic works well for guided canvas painting because it dries relatively quickly, cleans up with water while wet and can be layered when a colour needs more coverage.
Light or very bright colours can provide less coverage in our kits, so let the first layer dry and add a thin second coat if a printed number or line still shows. Keep each pot closed when you are not using it. Remove excess paint from the brush before rinsing, and follow the product label and local guidance when disposing of leftover paint.
A kit removes the need to draw the composition or mix every colour from scratch, so you can concentrate on loading the brush, controlling the paint and seeing how acrylic layers behave. Our step-by-step paint by numbers guide covers the process from the first section to the finished canvas.
If you want to paint a personally meaningful subject, you can also create a custom paint by numbers kit from your own photo.
Summary: Acrylic vs Oil Paint vs Watercolour
- Acrylic is a forgiving all-round choice for a beginner: fast layers, water cleanup while wet and straightforward corrections.
- Oil offers the longest blending time and rich gradual transitions, but asks for more patience and material knowledge.
- Watercolour is the most portable and creates unique transparent washes, but corrections and water control take practice.
There is no objectively best medium. Choose the one whose pace and limitations sound enjoyable. If you simply want to discover whether painting is for you, acrylic is often a straightforward place to begin.
Frequently Asked Questions
Which paint is best for beginners: oil, acrylic or watercolour?
Acrylic is a straightforward starting point for many beginners. It dries quickly, cleans up with water while wet and lets you paint over many mistakes after the first layer dries. Oil offers more blending time but requires patience; watercolour has a simple setup but transparent mistakes are harder to hide.
What is the main difference between oil and acrylic paint?
The binder and drying process are different. Oil paint uses a drying oil and remains workable for longer as it cures through oxidation. Acrylic uses an acrylic polymer emulsion and sets as water leaves the paint film. In practice, oil gives you longer blending time, while acrylic makes fast layering and wet cleanup easier.
Is oil painting harder than watercolour?
They are difficult in different ways. Oil asks you to understand slow drying, layering and the materials in your chosen system. Watercolour asks you to plan light areas and control water because the transparent paint is difficult to cover. Acrylic is usually more forgiving than either for a first painting.
Can you use acrylic and oil paint in the same painting?
Artists commonly use fully dried acrylic as an underpainting beneath oil colour, but acrylic should not be applied over an oily paint film. Use products intended for the technique, let layers dry as directed and follow the paint manufacturer's guidance when combining materials.
What type of paint is used in paint by numbers kits?
Our paint by numbers kits use pre-mixed water-based acrylic paints. Acrylic dries relatively quickly, cleans up with water while wet and can be built in layers. Light or very bright colours may need a second thin coat for even coverage.
