Opened Model Magic can be stored in an air-tight container but should be used within a few days, as it is designed to dry and harden over a brief period of time.

Crayola® Air-Dry Clay can be sealed once your piece is completely dry after 72 hours. Once dry, we suggest using an acrylic varnish. Make sure to test its compatibility with the varnish before applying it to a finished piece.

Sealing your work will not waterproof it. Exposure to water and outdoor elements will have a negative effect on the Air-Dry Clay, so we recommend displaying your sculpture indoors.

When creating with Crayola® Air-Dry Clay, we recommend forming your sculpture into a 3D solid structure. If you feel an armature is necessary, it’s best to use one that allows a small amount of give, such as crumpled aluminum foil. Using a rigid armature can lead to cracking, as it doesn’t accommodate the clay’s natural constriction during drying.

Depending on the size of the decorative objects, we recommend using white school glue, Crazy Glue, or Gorilla Glue to adhere objects like stones, beads, glitter, moss, etc., to thoroughly dry Crayola® Air-Dry Clay pieces.

To attach a piece of Air-Dry Clay to wood, an adult should roughly sand the wood where the clay is to be placed. Once the clay has thoroughly dried, use a small amount of white school glue, Crazy Glue, or Gorilla Glue to adhere the Air-Dry Clay to the wood surface.
