ACTÍVA Permastone mixes easily with water and reproduces the finest detail. Permastone is the ideal casting compound when permanent break-resistant castings are desired. It handles like plaster and has a stone-like finish.
Even if it happens to break, the fracture is clean and easily glued/fixed. It can be painted as it dries white with acrylics, oils, watercolors, tempera or any other finish!
Add 1 ½ parts Permastone into 1 part cold water in a clean disposable mixing container or bag. Mix gently and slowly until you reach a pancake batter consistency (to speed up setting time use warm water instead of cold). 2. Pour mixture into prepared mold, then gently tap or vibrate mold to release air bubbles.
