Air Dry Clay for Beginners: Types, Drying Tips and Painting

Air dry clay is the easiest way to start sculpting at home: no oven, no kiln, just shape it and let it harden in the air. This guide to air dry clay for beginners explains the different types we stock, how long they take to dry, how to avoid cracks, and how to paint and protect your finished work.

What is air dry clay?

Air dry clay is a modelling clay that hardens as the water in it evaporates. It is soft and easy to shape, can be smoothed with a damp finger, and becomes hard and light once dry. Unlike oven-bake polymer clay, it needs no heat at all, which makes it a favourite for school projects, children’s crafts and home décor.

Air dry clay vs oven-bake polymer clay

• Air dry clay hardens by itself over one to several days. It is good for larger pieces such as pots, bowls, figurines and wall décor. It is usually painted after drying, and it is not waterproof.
• Oven-bake polymer clay stays soft until baked, comes in bright ready-mixed colours and is stronger in small, thin pieces such as earrings and charms. See our oven-bake polymer clay guide.

How to work with air dry clay

1. Knead the clay for a minute or two until soft and even.
2. Shape your piece. Keep walls an even thickness, ideally no thicker than about 1–2cm, so they dry evenly.
3. Join pieces by scratching both surfaces, adding a little water or wet clay, and pressing them together firmly. Smooth the seam with a damp finger.
4. Smooth the surface with a slightly damp finger or sponge. Too much water makes the clay sticky and can cause cracks.
5. Dry slowly at room temperature, away from direct sun, fans and heat. Turn the piece over now and then so the bottom dries too.

How long does air dry clay take to dry?

Thin pieces are usually dry in about 24 hours. Thicker pieces can take several days, especially in humid weather. Always follow the drying time on the pack. A piece is fully dry when it feels room temperature (not cool) and has turned lighter in colour all over.

How to stop air dry clay cracking

• Dry pieces slowly. Drying in the sun or with heat makes the outside shrink faster than the inside.
• Keep thickness even, and hollow out or build thick shapes over a core such as foil.
• Fill small cracks after drying with a paste of clay and water, then smooth and let it dry again.
• Keep unused clay tightly wrapped so it doesn’t start drying in the pack.

Painting and sealing

Once completely dry, air dry clay can be painted with acrylic paint; see our acrylic paint guide. Seal the finished piece with a varnish such as Mont Marte Gloss Clay Varnish, which is made for both polymer and air dry clay. Sealing protects the surface, but air dry clay is still not waterproof, so don’t use it for vases that hold water or for food and drink.
