In liquid form.

Clarifications - Instructions for Use

Catalyst usage rate: 2% (100g of silicone corresponds to 2g of catalyst).

Using less catalyst than recommended will not harden the mold.
Using more catalyst will make the mold stiff.

If the silicone has not been mixed well with the catalyst, there is a risk that the mold will remain liquid in some places.

Be careful how you pour the silicone mixture into the model. Pour from above, and if bubbles appear, break them with a needle or wooden straw.
