Nearly every paint by numbers kit you can buy today comes with acrylic paint. Water-based, pre-mixed, and sorted into small numbered pots so you never have to blend a thing. That is the short answer. The longer one is more interesting, because not all acrylic is created equal and a handful of kits break the mold entirely.

Why acrylic won

Acrylic dries fast, cleans up with plain water, and stays put once it cures. For a kit meant to land on a beginner's kitchen table, that combination is hard to beat. There is no turpentine, no lingering solvent smell, no waiting three days between layers. You dip, you fill a region, and by the time you have worked across the canvas the first sections are already touch-dry. On a 40x50cm canvas most people finish a painting session and come back the next evening to a surface that is completely set.

The paint arrives semi-opaque and slightly thick, roughly the consistency of soft yogurt. That thickness matters. It lets a single coat cover the printed numbers underneath, which is exactly what you want. Thin, runny paint is a red flag for a cheap kit, and it usually means you will be doing two or three coats per region just to hide the grid.

Pigment load separates the good from the forgettable

Here is where price shows up. Budget kits often stretch their pigment with filler and water, so color 14 looks washed out and needs a second pass. Better kits pack more actual pigment into each pot, so coverage is one and done and the finished piece has real depth. If you have ever wondered why one $19.95 kit looks flat and another looks like a small oil painting, this is usually the reason. Our acrylic vs oil breakdown digs into how the two behave differently on canvas.

The rare exceptions

Oil-based kits do exist, mostly aimed at experienced painters who want longer blending time and that buttery finish. They cost more, smell stronger, and take days to dry, so they are a niche choice. Some very cheap children's sets use tempera or a watery poster paint instead of true acrylic, which is fine for a rainy afternoon but chips and fades over the years. If longevity matters to you, stick with acrylic.

Living with acrylic: the practical stuff

Acrylic's one quirk is that it dries in the pot if you leave the lid off. Ten minutes of exposure and the surface starts to skin over. Keep every pot closed until you need it, and only open one number at a time. A drop or two of water can loosen paint that has thickened, though genuinely hardened paint is usually gone. We wrote a full rescue guide on reviving dried-out paint if you have hit that wall.

A typical kit ships with somewhere between 24 and 48 numbered pots. The paint itself is safe, non-toxic on reputable kits, and washes off skin and most fabric while wet. Once it dries on clothing, it stays, so an old shirt is your friend. Beyond the paint, the brushes and a little water cup are the only supplies you truly need, though a few extras help. Our rundown of supplies worth having on hand covers what actually earns its place on the table.

So what should you look for

When you shop, the paint is the part you cannot see in a photo, which is exactly why it is worth checking reviews for words like streaky, thin, or dried on arrival. A quality kit gives you thick, high-pigment acrylic that covers in one coat and stays vivid for years on the wall. That is the difference between a project you frame and one you quietly retire to a closet. If you are picking your first one, start with something in our beginner-friendly collection, where the paint quality is dialed in for people still learning their touch. Ready to browse more broadly?
