Sculptamold is a dry, white, non-toxic compound that combines the best features of clay, plaster and paper mache'. After shaking closed bag to blend contents, add water to Sculptamold as directed on bag and begin modeling. Sculptamold sets in 30 minutes, so prepare only as much as can be used in that time. Sculptamold clings to almost all clean surfaces and does not shrink, so it can be applied to an armature or any core without fear of cracking. Finished pieces are very lightweight, strong and durable and may be carved, sanded or shaped with tools.
