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.
