Preparing the Original Model To create a mold in silicone rubber and plaster, the first step is to prepare the original model. This can be any object you wish to replicate. Make sure the model is clean and free from dust or dirt that could affect the final result.

Making the Silicone Rubber Mold Once the original model is ready, proceed with making the silicone rubber mold. Pour the liquid silicone rubber into a container and immerse the model inside, ensuring it is completely covered. Let it dry for the necessary time according to the manufacturer's instructions for the silicone rubber.

Pouring Plaster into the Mold Once the silicone rubber has hardened, pour the plaster into the mold. Prepare the plaster following the instructions on the package and pour it gently into the mold. Ensure the plaster is evenly distributed and let it dry completely before moving on to extracting the mold.

Extracting the Mold and Finishing Once the plaster has solidified, carefully extract the mold from the original model. If needed, you can refine the mold by smoothing or painting it as desired. The plaster mold is now ready to be used as a replica of the original.
