Short summery of use:

  • After preparing the plasticine base with a wall of more plasticine properly (see videos), measure the mould to find out the amount of silicone needed.
  • Increase the amount by at least 15% to account for not being able to remove 100% of the silicone from the tub when pouring.
  • Mix for 2 minutes per 100 grams approximately. 50% per tub. Do not contaminate either tub with the other tub contents, so avoid using the same knife.
  • Allow the mix to stand for 10 to 15 minutes to allow air bubbles to escape.
  • Pour the rubber at one end of the walled base only and allow the flow of silicone to naturally travel over the entire surface of the base.
  • After the entire base is covered you can empty the remaining rubber in your mix into the base to top it up.
  • Leave overnight to cure at room temperature (20 degrees Celsius). Put in a fridge for 2 hours to harden the plasticine to aid removal.
  • Remove the plasticine wall carefully then peel the base from the new mould half.
  • Transfer the tool and ingate to the new mould half and prepare for the second half pouring the same way you did the first.
  • After pouring the second half, leave overnight again to cure. Put in fridge again to harden plasticine. Remove the walls and separate the moulds. Remove the master and ingate.
  • Clean the moulds of all plasticine and trim the moulds up, as seen in the videos provided.
