To fix cracks in air dry clay you should smooth them out with a wet finger. After that use a clay sealer. Add water to the clay if it’s too dry. Keep the clay moist. Work with small pieces at a time and avoid excessive handling.
Air dry clay is a great way to make sculptures, decorations, and other items since it doesn’t require a kiln to harden.
However, it’s prone to cracking if not handled correctly.
Here are a few tips for avoiding or fixing cracks in air dry clay:
- Don’t overwork the clay. Work with small pieces at a time and avoid excessive handling.
- Keep the clay moist. If it starts to crack, you can add a little water to help it bind together again.
- Use a clay sealer. This will help protect your creations from cracking, chipping, or breaking.
With these tips in mind, you can create beautiful sculptures and other items out of air dry clay without worrying about them cracking.
What are the causes of cracks in air dry clay?
One of the most common causes of cracks in air dry clay is dehydration. When the clay loses moisture, it becomes brittle and can easily crack.
Another common cause of cracking is temperature changes. If the clay is exposed to extreme temperatures – either too hot or too cold – it can also crack.
Also, if the air dry clay is not given enough time to cure properly, it can also crack.
If you notice a crack in your air dry clay sculpture or craft, there are several ways to fix it.
One way is to use a sealant or varnish on the cracked area. This will help protect the clay from further moisture loss and cracking. You can also try using a glue gun to attach pieces of plastic or metal over the cracked area until it dries completely.
Another way to fix cracks is to simply fill them in with more air dry clay. Make sure the area is clean and dry before applying the new clay. Allow it to dry completely before painting or varnishing.
You can also try using a soldering iron to repair cracks. This method works best on small cracks. First, clean the area around the crack with a wire brush.
Then, apply a thin layer of solder to the crack. Heat the solder with the soldering iron until it melts and fills the crack. Allow it to cool and harden before sanding smooth.
How to fix small cracks in air dry clay
Small cracks in air dry clay can be fixed by using a thin layer of superglue over the crack. Let the glue dry completely before painting or varnishing the piece.
If the crack is still visible, you can try using a bit of putty or sculpting clay to fill it in. Once dry, sand the area smooth and repaint or varnish as desired.
If you have a large crack, or multiple cracks, it may be best to start over with a new piece of clay.

How to fix large cracks in air dry clay
When it comes to clay, there are two main types: air dry and oven bake. Air dry clay is the type that doesn’t require an oven to harden, and is typically used for smaller projects ornaments, figurines, etc.
Oven bake clay, on the other hand, is what you’ll need for larger projects like pots, plates, etc.
While both types of clay have their own unique strengths and weaknesses, one common problem that all clays face is cracking.
This can be a major issue when it comes to larger projects, as even a small crack can cause the entire thing to fall apart.
In this section, we’re going to show you how to fix large cracks in air dry clay using just a few simple tools.
The first thing you’ll need to do is gather your supplies. For this project, you’ll need:
- Air dry clay
- A paintbrush
- A piece of cardboard or paper
- A rolling pin
Now that you have everything you need, it’s time to get started fixing.
Start by wetting the paintbrush and lightly dampening the cracks in the clay. You don’t want to soak the clay, just make it slightly more pliable.
Next, take the rolling pin and roll it over the piece of cardboard or paper. This will help to flatten out the clay and make it easier to work with.
Once the clay is flattened, use the paintbrush to apply a thin layer of water over the cracks. This will help the clay adhere to itself.
Now, take the flattened clay and press it gently into the cracks. Use your fingers to smooth out the clay and make sure there are no air bubbles.
Allow the clay to dry completely before moving on to the next step.
Once the clay is dry, you’ll need to sand it down until the cracks are barely visible. You can use a fine-grit sandpaper for this or even a nail file.
Once you’ve sanded down the clay, your project is finished.
Clay projects are a great way to express your creativity, but they can be frustrating when things go wrong.
Luckily, with a little patience and the right supplies, fixing cracks in air dry clay is a fairly simple process. So don’t give up on your project just yet.
Tips for preventing cracks in air dry clay
Air dry clay is a type of modeling clay that doesn’t require baking in an oven. It’s popular with artists and crafters because it dries to a hard, durable finish.
However, if it’s not handled properly, air dry clay can crack and crumble. In this article, we’ll give you some tips for preventing cracks in air dry clay.
Don’t overwork the clay
If you work the clay too much, it will become tough and brittle. This makes it more likely to crack when it dries.
So try to avoid overworking the clay, and be especially careful when shaping delicate pieces.
Keep your pieces moist while they’re drying
If your pieces are allowed to dry out completely before they’re finished, they’ll be more likely to crack later on.
Try to keep them moist by spraying them with water occasionally as they’re drying.
Avoid sudden changes in temperature
Air dry clays are sensitive to changes in temperature, so avoid exposing them to sudden changes.
For example, don’t put them in the fridge to cool down quickly, and don’t leave them in a hot car.
Don’t place your pieces in direct sunlight
Direct sunlight can cause air dry clay to crack and crumble. So try to keep your pieces out of direct sunlight, especially while they’re drying.
Use a slow-drying method
If you’re in a hurry, you might be tempted to speed up the drying process by using a hair dryer or placing your pieces in an oven.
However, this is not recommended as it can cause the clay to crack.
If you need to speed up the drying process, try using a fan instead.
Store air dry clay properly
When you’re not using it, be sure to store your air dry clay in a cool, dry place. And make sure the container is securely closed so that the clay doesn’t dry out.
Follow these tips and you should be able to avoid cracks in your air dry clay projects. If you do end up with a cracked piece, don’t worry – there are ways to fix it.
Alternatives to air drying clay
There are a few alternatives to air drying clay. One is to use polymer clay, which is made from plastic and can be molded into any shape. It dries hard and can be painted with acrylics or enamels.
Another option is paperclay, which is made from paper pulp and water. It’s very soft when wet but hardens as it dries. It can also be painted with acrylics or watercolors.
A third option is self-hardening clay, which doesn’t need to be baked in an oven. It will air dry on its own, but it can take up to 24 hours to harden completely.
So there are a few different kinds of clay that you can use depending on your project.
Air drying clay is great for beginners because it’s easy to do and doesn’t require any special equipment.
But if you want to try something different, polymer or paperclay might be a good option. And self-hardening clay is perfect if you don’t have access to an oven.
