Preparing the Object for Mold Making

6 simple steps

1. Clean the object – remove any dust or debris.
2. Apply a release agent – this stops the silicone from sticking. Petroleum jelly, cooking spray or a release agent work well.
3. Seal any porous surfaces – use epoxy or polyurethane to fill in any holes or crevices. This stops air bubbles forming in the mold.
4. Create an alignment key – place grooves/marks on the object and its container. These act as guides when aligning the mold halves later on.
5. Secure the object – use hot glue or tape to keep it in place.
6. Create a wall – use clay or foam board to build a wall around the object, with extra space. This’ll rigidly hold the liquid material.

A friend once didn’t seal any porous surfaces when casting concrete statues and ended up with cracked molds

Mixing and Pouring the Silicone Mold Material

Mixing and pouring the silicone mold materiala must for a successful mold3 steps:

1. Prepare the silicon material with the catalyst. Thoroughly mix with a spatula or stick for 2-3 minutes, with no visible streaks.
2. Pour the mixture into a separate container for stirring. This helps ensure no air bubbles are present.
3. Slowly pour into the frame, starting from one corner. Don’t overfill or underfill. Then wait at least six hours before removing it.

Pay attention when mixing and pouring to ensure a successful mold

Candles, resin, and concreteSafety must be taken when handling the materials

1. Mix the silicone material following instructions.
2. Carefully pour the mixture around the object for complete coverage.
3. Cure, then remove the mold.
4. Clean it with soap and water before use.

Take note: Molds made from non-food-safe materials should not be used with food or drink.

1. Get the object ready for the mold by cleaning it and adding a release agent if needed. Different materials require different types of silicone molds, so choose the right kind.
2. Mix the silicone according to the manufacturer’s instructions, stirring it well. Pour the silicone over the object and use a brush/spatula to remove any air bubbles. Let the mold set overnight.
3. For cosplay armor, use epoxy putty to make intricate molds before applying silicone. To make soap, add transparent dye before pouring the silicone into the mold.
4. Preparing your object is essential. Remove dirt and debris and apply the release agents carefully. For more complex molds, use two-part techniques with a support shell like hydrocal/ultracal plaster for added stability.
