What exactly is acrylic paint?
Before we delve into the actual question, let's take a brief look at the chemistry behind it. Acrylic paint is a water-based dispersion paint: color pigments are suspended in an acrylic resin binder. The water evaporates as it dries, leaving behind an elastic, waterproof plastic film.
Acrylic paints are versatile and allow for a variety of techniques. They can be used on virtually any grease-free painting surface. The flexibility and very good adhesive properties of acrylic paint ensure that it remains intact even on a moving surface – even thick layers of paint do not crack when drying.
This everyday usability has made acrylic paint the most popular paint for hobby artists. Acrylic paint adheres to a wide variety of surfaces: paper, canvas, stone, wood, concrete – and also unglazed ceramics. A prerequisite for good adhesion is a grease-free, dust-free, and slightly absorbent surface. This point is precisely the key.
Acrylic paints are popular, widely available, and easy to buy online or at craft stores.
Does acrylic paint adhere to ceramics?
The short answer: Yes – but not equally well on all ceramics. It depends critically on whether your piece is glazed or unglazed.
Unglazed ceramics (bisque/raw ware)
Bisque ware is fired once, unglazed, and therefore still absorbent. Acrylic paint can adhere well to this porous, rough surface – similar to stone or untreated concrete. The pores literally provide grip for the paint.
Bisque ware: Fired, but still without glaze
Glazed ceramics
On glazed ceramics, the situation is much more difficult. A glaze is essentially a melted, glass-like layer – smooth, dense, and hardly absorbent. Acrylic paints do not adhere particularly well to smooth surfaces. However, light roughening of the surface (sandpaper, 400 grit) can improve adhesion.
"On unglazed bisque ware, acrylic paint adheres surprisingly well. On finished, smooth glaze, it requires more effort – and you should keep expectations for durability realistic." Koray from Formwerk
When and where acrylic paint truly works
To be fair, there are definitely scenarios where acrylic paint on ceramics is a sensible choice.
Acrylic paint on ceramics – these applications make sense
- Decorative objects without food contact: Vases, figurines, flower pots – here the question of food safety is irrelevant.
- Quick design projects without a kiln: Anyone who doesn't have a kiln and just wants to decorate can start spontaneously with acrylic paint.
- Children's and school projects: Acrylic paint is versatile and easy to handle – even for children (pay attention to labels!).
- Upcycling old ceramic pieces: Spruce up an old terracotta pot? Acrylic paint is ideal for this.
- Acrylic paint with special glass medium: With an acrylic-glass medium, you can create your own paints that adhere to glass, tiles, or glazed porcelain – and are permanently fixed by baking in the oven at approx. 160 °C.
The clear limitations of acrylic paint on ceramics
Now it gets important – especially if you want to design dishes or objects for daily use.
1. Acrylic paint is not food-safe
This is the most critical point. Standard acrylic paint is not suitable for contact with food. Glazes and paints applied to ceramic objects can contain heavy metals that leach into food – including lead and cadmium. For commercially available acrylic paint, the corresponding testing and certification for food contact is completely missing. Make sure to always leave drinking and eating edges clear.
⚠ Important Note
Never use standard acrylic paint on the interior surfaces of cups, bowls, plates, or cookware. The paint is not suitable for food contact and can dissolve when washed or by acids (coffee, fruit juices). If you want to design functional tableware, food-safe glazes such as the Amaco Stoneware Glaze Textured Turquoise with subsequent firing are the right choice.
2. Acrylic paint cannot be fired
Important: Acrylic paint must not be fired in a ceramic kiln! At high temperatures of 800–1300 °C, the paint would simply burn. It is not designed for the firing process – and therefore can never achieve the strength and durability that a real glaze or underglaze paint possesses after firing.
3. Durability and dishwasher resistance
Without special sealing, acrylic paint on ceramics will not last long with daily use. Even with sealing, true dishwasher resistance is difficult to guarantee with standard acrylic. "Conditionally dishwasher safe" is the best you can achieve – and that is an important difference from professional ceramic paints.
4. No substitute for professional ceramic paints
Real ceramic underglazes and glazes fuse with the clay into an inseparable unit. After firing at approx. 1000 °C, they are scratch-resistant, dishwasher-safe, and food-safe. Acrylic paint simply cannot achieve this result. Here you can find stoneware glaze for high temperatures from the manufacturer Amaco.
Amaco's professional Potter's Choice glaze is a better choice for ceramics than acrylic paint. The "Food Safe" label at the bottom right also confirms its food safety.
Acrylic paint vs. real ceramic paints: the direct comparison
So you can see at a glance where acrylic paint is strong – and where it can't keep up:
| Property | Acrylic Paint | Underglaze + Firing | Porcelain Paint (Oven) |
|---|---|---|---|
| Kiln needed | No | Yes (800–1300 °C) | Only oven (~160 °C) |
| Food safe | No | Yes (after firing) | Partially (check manufacturer info) |
| Dishwasher safe | No / conditionally | Yes | Partially (up to 50 °C) |
| Adhesion to bisque ware | Good | Very good | Medium |
| Adhesion to glazed surface | With preparation | Only overglaze/luster firing | Good (after baking) |
| Price / Availability | Cheap, everywhere | Specialty stores | Craft stores |
| Suitable for decorative objects | Very good | Yes | Yes |
| Suitable for dinnerware | No | Yes | Conditionally |
Step-by-step: Painting ceramics with acrylic paint
If you want to use acrylic paint for a decorative project without food contact, here's the best way. This guide applies primarily to unglazed ceramics or terracotta.
Clean the surface
Wipe your ceramic piece with a lightly damp cloth and thoroughly remove dust, grease, and dirt. Grease is the enemy of any adhesion. For glazed ceramics, light sanding with fine sandpaper (400 grit) helps improve adhesion.
Optional: Apply primer
On glazed or very smooth surfaces, a thin layer of acrylic primer (gesso) significantly improves adhesion. On porous bisque ware, this step is often not necessary.
Paint in thin layers
Apply the acrylic paint in thin, even layers, allowing each layer to dry completely before applying the next. This method ensures a smooth and vibrant finish.
Allow to dry for at least 24 hours
Before sealing, the acrylic paint must be completely dry. For full curing, allow at least 72 hours – even if it appears dry on the surface sooner.
Seal
Protect your work with a clear acrylic sealer or varnish. More on this in the next section.
✦ Pro tips from Formwerk Berlin
- Metallic paints work particularly impressively on ceramics – they also hide small imperfections.
- Masking tape for clean geometric edges: Apply the tape to the dry base coat, paint over it, and peel it off while the paint is still slightly wet.
- Sponge instead of brush for even surfaces and interesting textures.
- Fixing Mistakes: As long as the paint is still wet, it can be wiped off with a damp cloth. Once dry, only isopropyl alcohol will help.
Sealing – how to make the paint last longer
By sealing your projects, you not only ensure a more visually appealing look but also a significantly extended lifespan. You have various options for this:
✦ Sealing Options at a Glance
- Acrylic Varnish (matte / satin / high gloss): Ideal for art objects and decor. Protects against UV radiation and preserves color brilliance. Low-odor, water-based variants are recommended.
- Clear Lacquer (Spray): Particularly suitable for objects with frequent mechanical stress. Solvent-free clear lacquer is ideal as it does not attack acrylic paint. Spray cans allow for a particularly even application.
- Acrylic Glass Medium (for glazed surfaces): Improves both adhesion and durability on glazed ceramics – especially if you then bake it in the oven at approx. 160 °C.
An honest note on this: All artist acrylic paints are microporous and allow air and water to pass through the layers. No sealant can completely prevent this. For decorative objects, this is not a problem – for tableware, it means that acrylic paint is not a permanent solution in the long run.
⚠ Even after sealing
Surfaces painted with acrylic paint should not come into contact with food. Always leave drinking, biting, and eating edges free.
Our Conclusion at Formwerk Berlin
Acrylic paint on ceramic – it's possible, and for certain projects, it's a practical, creative solution. We at Formwerk Berlin see it primarily as a good tool for quick decor ideas, upcycling projects, and anything that doesn't require food contact.
However, if you want to create real ceramics – hand-thrown mugs, self-potted bowls, everyday tableware that can go in the dishwasher – you can't get around real ceramic paints. Only paints that are coated with an overglaze after painting and fired in a kiln are truly scratch-resistant, dishwasher-safe, and food-safe. This is the difference between a decorative art object and real functional tableware.
In our shop, you'll find professional underglaze colors, engobes, and glazes for all firing ranges – curated by us for the Berlin pottery community. And if you don't have your own kiln yet: many local pottery studios in Berlin offer firing services. You design, we take care of the fire.
One last recommendation: If you want to try acrylic paint on ceramic, start with a cheap terracotta pot from the hardware store. No pressure, no expensive material – just paint, brushes, and the feeling of how ceramic reacts as a substrate.
Have fun with your pottery work, and if you have any questions, feel free to contact us! With heart, patience, and a good community behind you, you'll soon be holding wonderful results in your hands. Happy Potting! 🥰
