1. Take a small amount of paste from the jar with component “A”, compact it by rolling it into a ball. Weigh it.
2. Form a ball of equal volume and weight using component “B”.
3. Mix component A and component “B” until a mixture of uniform color is obtained.
4. Be sure to use the silicone mass immediately since you have only 3-4 minutes after mixing the components before the mass starts to harden. You can press the object you are copying into the silicone mass, apply the silicone mass directly onto the object, or create the "rim" type of mold: For example, if crafting the mold for coaster or tray, you can make the rim out of silicone mass with your fingers, attach to the hard and glossy film/plexiglass, slightly press it and give it a smooth and glossy inner surface using a any smooth tool (for example, a lid from a jar with silicone).
5. Leave the mold until completely cured - 7-8 minutes.
⏱ Please note that I-GUM FAST rubber has a working time limit of 3-4 minutes - after mixing the components until it starts to harden.
