Air-dry clay is a fantastic crafting medium and a lot of people use it to create homemade crafts. Because you don’t need a kiln to fire it, it’s much more accessible than ordinary clay, so many people opt for it when they want to sculpt gifts and other art. However, it doesn’t look very attractive in its basic form.
You’ll probably want to paint your finished project so that it looks complete, and that might leave you wondering whether air-dry clay will take paint – and if so, what kind. You don’t want to wreck your carefully crafted project, after all.
Can you paint air-dry clay? You can paint air-dry clay, but you must make sure it is completely dry. Most kinds of paint will work on air-dry clay, but acrylic is a popular choice. Watercolor should also work, but you need to be careful about not getting the clay too wet, or you may ruin its shape, or cause it to crack.
Is it Okay to Paint Air-Dry Clay?
You can paint on air-dry clay once it has dried fully. Depending on how large your project is and the kind of clay you use, it could take up to a week to dry. Many projects will be dry and ready to paint within 24 hours, but large projects will need a lot longer. You can speed up the drying process by increasing the amount of airflow over the clay.
As soon as your project is dry, you can paint it. However, if you paint it too early, you could run into a couple of different issues. Firstly, the wetness of the paint may spoil the surface of your craft. Making air-dry clay wet causes it to turn sloppy. This can change the appearance of the clay, and this will potentially ruin any details you have added.
Furthermore, adding too much water to the clay can cause it to crack as it dries. If you put wet paint on an already damp surface, you increase the chances that the clay will start to split. This will ruin the whole project, so it’s really important to avoid it. Don’t make your air-dry clay wetter than it already is.
How Do You Tell If Your Air-Dry Clay is Dry Enough to Paint?
It can be a challenge to tell whether your clay is dry, but dry clay will be a lighter color than wet clay. Inspect your project from all angles, and if there are no darker spots, the clay is probably close to being dry. Next, gently press the tip of your finger against it. If there is any give, the clay is not yet dry.
The clay gets harder as it dries, so if you can press the clay and it squishes, it isn’t dry. Your clay should not squash under pressure if it’s ready to paint. Don’t press with your nail or any sharp object, however, as this could damage the clay even if it is dry. Gentle pressure from your finger should be all you need to test its dryness.
Your clay project should also sound hollow if you gently tap it against something. As the moisture evaporates from the clay, it will leave little air pockets, and this means your clay is pretty porous when it’s completely dry. You should be able to hear this when you tap the clay. Again, do this test gently so you don’t risk damaging your sculpture.
What Kind of Paint Can You Use on Air-Dry Clay?
You can use a wide variety of paints on air-dry clay, but many people recommend acrylics, because you’ll get strong colors and you won’t need to add too much water to the clay. Acrylic paints are bright and attractive, and generally easy to use, so they’re ideal in many ways.
Acrylic paints offer quite a few advantages, including being durable, easy to buy, and easy to thin. They also dry quickly and can be used on many different surfaces. They will look great on your clay project, although you will need a chemical to clean your brushes after you have finished painting.
You can also use watercolor paints on your air-dry clay, but you need to be careful not to make them too wet, or you could run into the issues mentioned above. Work in thin coats and allow each layer to thoroughly dry before you add more.
Some people use other kinds of paint, too. Oil paints are less common, but they can be used. Bear in mind that they tend to smudge, and they can be challenging to clean up – so they’re really only an option for skilled professionals who aren’t likely to make mistakes while painting.
It’s important to note that you may need several coats of paint to achieve bright colors, even if you use acrylics. Because air-dry clay is so porous, it will soak up color and requires quite a lot.
Do You Need to Prime Your Air-Dry Clay?
It’s important to be aware that air-dry clay is very porous and it may soak up a lot of paint before it starts to take on the paint’s colors properly. A lot of people therefore prime their clay projects with gesso before they start painting. Allow the gesso to fully dry before adding paint.
This isn’t strictly necessary, but it will help the paint to spread evenly, and it also forms a protective barrier between the clay and the paint. This is an advantage if you’re using quite wet paint, because it will stop the moisture from getting into the clay and causing problems.
If you’re going to put oil paint on your air-dry clay, add at least 3 layers of gesso before you start painting.
Air-dry clay can be painted, but only once it has completely finished drying. You will need to leave your project for at least 24 hours, or up to a week if it’s a large project. Make sure it’s exposed to plenty of moving air and regularly turn it, and then you can paint it when it is dry.
