Description FoamWorx Air Dry Clay is perfect for adding intricate details to cosplay costumes, craft projects, models, and props. Depending on the thickness of the application, it typically takes about 24 to 48 hours to dry. Thicker pieces will take longer to cure. Once dry, FoamWorx Air Dry Clay transforms into a dense material resembling EVA foam, which can be cut, sanded, glued, primed, and painted. The clay adheres effectively to various adhesives, including super glue, hot glue, and contact cement. FoamWorx Air Dry Clay is ideal for filling seams and adding details to your foam builds. You can either press it into molds or sculpt it by hand; using water can help smooth the surface.
