RTV SILICONE STEP BY STEP

Weigh RTV and Hardener according to instructions

Different RTV Silicones have different mixing ratio. Check the instructions before mixing.

Mix well and stir slowly

Stir RTV Silicone well for a good 5 to 10 minutes to make sure the thicker RTV liquid mixes well with the hardener. If the liquids are not mixed well, the mold will not harden. Stirring in a figure 8 motion and all around the edges of the mixing bowl helps.

Secure your masterpiece into a container or box

Make sure surface of masterpiece is clean and free from sulfur. Any item containing sulfur such as clays and plasterstin will inhibit the hardening and performance of the RTV Silicon Rubber.

Spray your masterpiece with silicone release agent or petroleum jelly

If your masterpiece is porous, the RTV Silicone will stick to it. Adding a layer of Silicone Release Agent or oil will help release the mold from the masterpiece.

Pour the RTV mixture slowly over the masterpiece

Do this slowly and carefully to avoid bubbles forming on the surface of the mold.

Wait for 24 hours before unmolding

ALGINATE STEP BY STEP

Fill up a bucket with water to the ratio or 2.5 to 3 times you would need alginate

For example for one adult hand, use 500g alginate powder and 2.5L of water.

Slowly pour the alginate powder into the water and stir fast

Keep stirring at the Alginate powder until all the powder is inside the bowl

Rapidly break up any lumps that will form

Use a whisk or a spatula and work very quickly. Do not take breaks until all the lumps have been smoothened out.

Quickly insert your hand or said body part into the mixture and stay still

The mixture will be cold and smells minty. This is normal. Stay very still for around 3 to 5 minutes to let the mold set.

Watch the color change from pink to green

Once the color changes from pink to green and the mold has congealed around your skin, the mold is ready.

Slowly remove your body part from the mold

Be gentle here so as not to tear the mold.

Immediately pour plaster into the mold cavity

Alginate is a one time use mold that needs to be used immediately after it is ready.

Once plaster has hardened, tear open the mold to retrieve it

If unsure, start with a small batch to cast a finger before attempting a larger mold
