RD-407 Mask Making Latex

Above: Anthony Giordano, assistant Prop Master for 'Saturday Night Live,'  begins the process of creating a latex mask. Anthony starts with an original clay sculpture. When complete, he will make a two-part plaster mold using CastRite. Once the mold is finished and cleaned of clay he will pour in ArtMolds' RD-407 Masking Making latex. The latex is allowed to sit for approximately an hour, then poured back out again.  What remains clinging to the sides of the plaster negative will dry over the next day and be peeled out to become the actual mask.  It is the trimmed, sanded, painted and finished.

It is allowed to stand for about 45-minutes and then the 407 is poured back into its receptacle. The mold is tilted upside to drain. It is allowed to dry overnight before it is demolded.which in turn sets the latex leaving a thin skin. Silicone and urethane molds can be used, but the results can be inferior as they do not have the same curing properties.
