The dry mould is opened and the clay which was the sculpture is cleaned out, leaving a solid, negative impression of the sculpture. The mould filled with latex which will be left to begin to thicken against the plaster forming a thick skin. When this skin has enough depth, the excess latex is poured out and the rubber is left to dry thoroughly before 2 part foam is poured into the mould to support the skin. After a bonding layer of Pros-Aide is applied, the skin is painted.
