New Techniques for Perfect Face Castings Page-4


When the plaster has set you can de-mold. Have a small box filled with Styrofoam popcorn at the ready. This will support the face mold hen it is removed from the model. Ask the model to lean forward and hold the mold in both hands. Use your finger to carefully slide under the mold between the alginate and the skin and slip your fingers around the edges. This will break the suction and the mold will fall off into the hands of the model. Carefully place it, face down, on the Styrofoam.


Face Casting Step 13 Figure 13. When the bandages are set, fiingers are inserted between the model's skin and under the alginate to break the suction. Once the suction is broken, the mold can be easily removed.

Casting the Face Mold

Make certain the mold is clean and free of any debris before you proceed with casting it.

Mix the casting plaster such as CastRite according to the directions on the package. Use your hand for mixing.


Face Casting Step 14Figure 14. The mold is inspected for any flaws or tears. Loose piece of alginate is removed to ready the surface for casting. 
With a 2-inch chip brush, paint the surface of the mold with the plaster. This is called the face coat and is the most important part of the casting process as this is what is seen. So brush carefully into all the nooks with an even coat.
Face Casting Step 15Figure 15. After the CastRite is mixed, a 'face coat' is painted in covering the entire surface of the mold. This coat assures that therewill be no air bubble visibile on the surface of the finished casting. 

Allow the face coat to set up with the surface still damp and pour in the plaster to fill the mold. While the plaster is still wet you can embed picture wire so that you have a method of hanging the finished face cast.

Face Casting Step 16Figure 16. Place the mold into a mold cradle (box filled with packing peanuts). Allow the face coat to set up, but not completely dry, and slowing fill the mold with the casting material. You can bury a picture wire in the wet plaster to use as a hanger when the plaster dries. 

Test the surface of the mold after three hours. It should be dry and firm and ready to de-mold.
