Decorative plaster for sculpture painting, 3D flowers, and relief art. The paste is ideal for 3D designs and holds formations like thin petals and finer details well. It can be used with stencils and is best applied with a palette knife. For best results, allow it to dry naturally (do not force dry with a heat gun). After complete drying, you may apply varnish on the project to protect the work from moisture and UV rays. Drying time depends on the applied thickness. For prolonged shelf life, tightly close the container after use. Works best with Little Birdie one-step Crackle Medium.
