How To Make a Polysulfide Rubber Mold of a Masterpiece

Step 1: Applying FMC Initial Coat

This da Vinci horse maquette was sculpted in Roma Plastilina. To begin, weigh out 100 parts of Part A and 12 parts of Part B of the polysulfide compound. Then carefully mix the FMC®-200 100A:12B. The initial layer is the 'print' or 'detail' coat and should be applied thinly. The rubber is easy to apply and should go on smoothly. Special attention is paid to the deep detail of the horse's mane with care being taken to work the rubber into the detail.

Apply the FMC® rubber to all surface area and allow the initial layer to become tacky before subsequent layers are applied.
