ABSTRACT:
A method for electrostatically coating plaster mandrels by making the mandrels electrically conductive, thereby facilitating electrostatic painting or spraying, by embedding a ground strap into the mandrel which is in an electrically conductive "green" or uncured state due to its free water content after it was slosh formed in a rotating mold. The plaster mandrels are then electrostatically coated before the green plaster dries and cures.
