The chemistry of acrylic paint is worth understanding before you pick up a brush, because it explains almost every quirk of the medium. Acrylic paint is pigment suspended in acrylic polymer emulsion, a water-based polymer that, when wet, stays workable and water-soluble. When it dries, the water evaporates and the polymer chains cross-link into a flexible, water-resistant film. The drying is not a chemical reaction but simple evaporation, which is why a thin wash can dry in minutes while a thick impasto passage takes an hour. Once dry, that polymer film is permanent. It will not re-dissolve in water. It will not yellow or crack over time the way linseed oil does. And it will bond to almost any non-oily surface without preparation.
That chemistry gives acrylic paint a flexibility no other painting medium matches. Thin it with water to the consistency of ink and it flows like watercolor. Use it straight from the tube and it holds palette knife marks and brushstroke ridges. Mix it with gel medium and it becomes viscous and semi-translucent. Add a retarder and it slows drying time enough for extended blending on the canvas. Since acrylic paints became commercially available in the 1950s, artists from David Hockney to Mark Rothko to Andy Warhol have used these properties in serious work. The medium attracted painters who wanted speed and flexibility, and it has grown more sophisticated since then.
This guide covers what you actually need to get started, the core techniques that matter most, specific things to learn from how Hockney and Rothko used the medium, and the common mistakes that frustrate beginners before they understand what is causing them.
What Makes Acrylic Different From Other Media
The honest comparison: oil paint dries through oxidation rather than evaporation. Because linseed oil oxidizes rather than simply losing water, a thick impasto stroke of Titanium White might feel dry to the touch in a week but remain chemically active and soft underneath for six months or longer. That slow cure gives oil painters extended time to work into wet paint and blend on the canvas. It also means each layer must be genuinely dry before painting over it, and in thick passages that takes weeks. Watercolor dries fast but is transparent by nature and almost impossible to make opaque without gouache. Gouache is opaque but reactivates with water and cannot be layered reliably.
Acrylic occupies a position none of these can: it dries fast enough to layer within a single session, opaque or transparent depending on how you dilute it, and cleans up with water. Those properties make it the most flexible starting medium available. The speed is liberating when you want to correct a passage or build layers. The water cleanup makes it practical for home studios and kitchen tables. The versatility from transparent wash to thick impasto means you can explore a wide range of approaches without switching media.
Materials: What You Actually Need
The art supply industry thrives on selling beginners more than they need. What follows is a minimum viable kit that covers everything a beginner needs and nothing else.
Paint
Start with six to eight colors. Student-grade acrylics including Winsor and Newton Galeria, Liquitex Basics, and Golden's student line are perfectly good for learning. Artist-grade paints have higher pigment concentration and better handling properties, but the cost difference is significant and your skill will improve faster than your ability to appreciate the difference. A useful basic palette includes a warm red (Napthol Red or Cadmium Red Medium), a cool red (Quinacridone Magenta), a warm blue (Ultramarine Blue), a cool blue (Phthalo Blue), a warm yellow (Hansa Yellow Medium or Cadmium Yellow), a cool yellow (Lemon Yellow), and Titanium White. Black is optional: learning to mix darks from complementary colors teaches you more about color relationships than opening a tube of Mars Black.
Brushes and Tools
Four brushes cover almost everything: a large flat (1.5 to 2 inches) for covering backgrounds and large areas, a medium filbert for general painting, a small round (size 2 or 4) for detail, and a palette knife for mixing and texture work. Use synthetic brushes, not natural hair. Acrylic is slightly abrasive and the polymer emulsion is harder on delicate bristles than natural bristles can handle over time. Do not buy expensive brushes until you know you like the medium.
Surface
Primed canvas boards are the most practical surface to start with: cheap enough to practice without anxiety, primed so the acrylic does not sink in and look dull, and rigid enough to work on without stretching. Stretched canvas works too. Gessoed wood panels are excellent but cost more. Whatever you use, make sure it is primed with gesso or the equivalent. Raw canvas absorbs acrylic unevenly and the paint sits on the surface with a flat, dull quality that does not reflect what the paint can do on a properly prepared surface.

Five Core Techniques
Wet-on-Wet Blending
Applying fresh paint over paint that is still wet lets the two colors blend on the canvas surface. With acrylics, you need to work quickly or use a retarder medium to extend the open time. This technique produces soft, gradated transitions and is particularly effective for skies, skin tones, and smooth backgrounds. The challenge is that hesitation lets the paint dry before you finish the blend. The solution is to mix enough paint on your palette before you start, so you are not slowing down to remix colors mid-blend.
Wet-on-Dry Layering
Waiting for each layer to dry completely before adding the next is the most characteristically acrylic approach. Because drying is fast, you can build multiple layers in a single session that would take days with oils. This method is ideal for adding hard-edged detail over a dried background, correcting shapes without muddying earlier colors, or building up complex color relationships one transparent layer at a time. David Hockney used wet-on-dry layering extensively in his California pool paintings, building flat areas of color in multiple passes to achieve that distinctive graphic clarity without any blended transitions.
Dry Brushing
Load a brush lightly with paint and drag it quickly across the surface, leaving broken marks that reveal the texture of the canvas or earlier paint layers beneath. Dry brushing is effective for rough textures, grass, hair, bark, and weathered surfaces. It creates visual energy when used in contrast with smooth, solid areas of color underneath.
Glazing
Thin paint with a glazing medium or a small amount of water until it is nearly transparent, then apply it over a dry layer of a different color. The layers optically mix and create depth that flat paint cannot achieve. A transparent glaze of Quinacridone Red over a dried layer of Yellow Ochre produces a warm orange with visual complexity that cannot be matched by simply mixing orange paint. This technique comes from the oil painting tradition but works well in acrylic because the fast drying time means you can glaze multiple layers in a single session. For a deeper look at how glazing and transparent layers work technically, see the guide to oil painting techniques.
Impasto
Applied thick and undiluted, acrylic paint holds the physical marks of brushes and palette knives, creating texture that has tactile presence as well as visual interest. You can build this further with a heavy gel medium mixed into the paint, which adds body without diluting the pigment. The resulting surface has ridges and peaks that catch light differently depending on the viewing angle. For beginners, impasto is one of acrylic's most immediately satisfying techniques: the marks stay exactly where you put them, and the resulting surface looks like it required skill to produce because it did.
What Hockney and Rothko Actually Did With Acrylics
Studying how established artists use a medium teaches more than exercises alone, because you see technique operating in service of a specific visual goal rather than as an end in itself.
David Hockney adopted acrylic paint in the mid-1960s after moving to Los Angeles. He was attracted by its flat, graphic quality, which suited his interest in Californian light and artificial surfaces like swimming pools and glass facades. "A Bigger Splash" (1967), now at Tate Modern, demonstrates this precisely: the hard-edged pool, diving board, and house are painted with geometric precision in flat areas of color built up through multiple dry layers. The white splash is entirely different: gestural, applied quickly with a large house painting brush in a single movement. The contrast between controlled flatness and gestural energy in a single 242-centimeter canvas shows how the medium can serve two completely opposite approaches simultaneously.
Rothko worked differently. In his late color field paintings, he built up very thin, transparent acrylic washes layered over each other until the surface had accumulated the depth and luminosity that made his work distinctive. A 2025 study published in the Journal of Cultural Heritage applied computational color analysis to Rothko's paintings and found that what appears as a simple field of color contains dozens of subtle hue variations and gradients that the human eye reads as atmospheric depth rather than flat paint. This is why a Rothko looks profoundly different in person from a reproduction: the color relationships are too subtle for digital capture.

Common Problems and Their Actual Causes
Most beginner frustrations with acrylic paint come from a small set of recurring problems that are easy to fix once you know what is causing them.
Paint drying on the palette before you use it: Acrylic on a standard plastic palette in a dry studio can skin over in ten minutes. Use a stay-wet palette, which is a damp sponge under baking paper, or a commercial equivalent. Spray your palette with water regularly. Golden's Open range uses a modified polymer that slows drying significantly at the cost of slightly different handling properties.
Muddy color mixes: Muddy mixes usually happen when complementary colors get combined unintentionally, either by not rinsing your brush between colors or by mixing warm and cool versions of the same hue. Keep your palette organized with warm colors on one side and cool colors on the other, rinse thoroughly between colors, and read the guide to color theory to understand why complementary pairs produce neutrals when mixed.
Overworking a drying surface: Once acrylic starts to dry, touching it with a loaded brush drags and lifts the drying film. The solution is to work decisively, place marks, and let them dry before returning. The speed that frustrates you in blending is an advantage in layering.
Brushes hardening during a session: If you set a brush down on the table with paint in the bristles for ten minutes, the acrylic starts to cure and the brush becomes difficult to clean. Keep brushes wet throughout the session in a shallow tray of water, and clean thoroughly with soap and water at the end.
Building a Practice
The fastest way to improve with acrylics is to paint regularly and deliberately. Spending two hours a week focused on a single technique, smooth color gradients one week and dry brushing texture the next, builds skills more efficiently than the same hours spent painting whatever seems interesting. Keep a dedicated small canvas or pad for experiments. Test color mixes before committing them to a larger work. Understanding how texture functions in painting will give your acrylic work more variety. And study how artists you admire actually use the paint by looking at their work in person when possible. Reproductions flatten texture and compress the color relationships that make the originals compelling.
Acrylic paint remains the most practical starting medium because it gets out of the way and lets you focus on learning to paint. Artists from Hockney to Rothko to Warhol found serious creative possibilities in it long after mastering other media. Starting with acrylics is not starting small. From here, compare it against watercolor technique, or deepen your understanding of composition to make your paintings more visually compelling. What are you planning to paint first?
