Step 1: Step 1 | Weigh

Weigh 2 equal parts of the silicone part A and part B (preferably using
an electronic kitchen scale). It’s advisable to lightly grease the object to be copied before use with grease such as Crisco, make sure your hands are also lightly greased. Place a plastic placemat on your workspace whilst working with the silicone.

Step 2: Step 2 | Mix

Knead and mix the paste for approximately 1 minute until you get a
homogenized paste and a uniform color is achieved. The work time of SILLI is about 10 minutes. If you wish to make more moulds or a bigger mould then you can prolong the work time by placing the silicones in the refrigerator. Never use too much at once.

Step 3: Step 3 | Mould

Press the object carefully, applying some pressure, in the silli plastique. Make sure all the details have been pressed into the SILLI. If necessary a thin layer of SILLI can be rubbed into the details of the object. The SILLI should cover the object completely, making sure the layer is thick enough. Rub over the mould with your fingertip for a smooth surface.

Step 4: Step 4 | Demould

Leave the mould to set for at least 2-3 hours at room temperature,
remove the object from the mould and now let the mould post-cure for a couple of days.

Want it to cure faster?

Place the mould in a pre-heated oven at 100 degrees C or 212 degrees F for faster post-curing. Make sure the silicones are fully cured before you use it. Thicker moulds take longer to cure! Wash the mould in the dishwasher on the highest temperature. The mould is ready for use.
