Health & Safety
Liquid silicone is a chemical and it does come with health & safety implications. It is your responsibility to read the below thoroughly and ensure you follow the instructions:
  • You MUST wear nitrile gloves 
  • Ensure you work with this resin in a well ventilated room
  • We advise you to wear safety goggles
  • Avoid skin contact
  • Keep hands away from eyes and face
  • We advise against eating, drinking or smoking while working
  • In case of eye contamination wash immediately with plenty of water for 15 minutes and consult medical advice
  • If swallowed, seek medical advice. Do not induce vomiting.

Basic Instructions
  1. First secure your original onto a flat surface - this could be acrylic sheet or old CD case. You can secure it with sulphur free plasticene or glue (Araldite or Superglue work well).
  2. Make a wall around your object, which isnt too far from your original otherwise you will use too much silicone. Ensure the wall is sealed so that the silicone doesnt leak out this is your mould box. Then mark a line about 5 or 6mm above the original.  This is the level where you will pour the mould-maker to.
  3. For an easy way to work out the volume of silicone you will need some rice pour it into the mould box and then tip it into a clear plastic cup. Mark the level that the rice reaches in the cup and then pour the rice out. This will give you the total volume that you need to make the mould. (The reason why you use rice rather than water is that you do not need to dry out the original and the mould box when you use rice. Water and silicone should not be mixed). You can spray the original with release agent (such as a silicone-free beeswax furniture spray) but it is not usually necessary.
  4. Give the mould-maker tubs a good shake before use.
  5. Mix equal parts, by weight (e.g. 100g and 100g), of Mould-Maker BASE and Mould-Maker CATALYST  one part blue and one part white.
  6. Put the marked empty clear plastic cup on a set of digital scales and set the scales to zero (tare). Pour the Mould-Maker BASE up to halfway to the mark on your plastic cup. Make a note of the weight of the Mould-Maker BASE. Take cup off scales.
  7. Put an empty plastic cup on the scales and weigh out the same weight of Mould-Maker CATALYST into the cup.
  8. You should now have a cup with blue Mould-Maker BASE in it and another with white Mould-Maker CATALYST in. (Using two cups makes it is easy to get the correct weight of each part - if you put too much in, you can take a bit out without contaminating any of it).
  9. Pour one cups contents into the other and mix for 30 seconds. Then pour the mixture into the other cup to gather up any silicone left behind. Mix for another 30 seconds. The mixture should be uniformly paler blue now. Let it stand for a few minutes to get rid of some of the air bubbles (ideally it should go in a vacuum chamber but they are expensive).
  10. You have a working time of 14-20 minutes (if your workspace/room temperature is around 23oC). The working time is shortened if the room temperature is higher.
  11. The next step is to coat the original with a thin layer of silicone mixture. You can do this either with a paintbrush or by pouring some in on top of the original and then tipping it out again, leaving a thin layer on top of the original. This is to ensure that there are no air bubbles next to the original, which will give you lumps on your casting.  You can use a straw to blow on bubbles and pop them. 
  12. Then pour the silicone in to the mould box; starting in one corner away from the original - this again is to avoid air bubbles on the original. Pour in a thin high stream (preferably at least 30cm higher than the mould-box), which will get rid of air. Gently tap the box to encourage air bubbles out.
  13. The mould will be hard in approximately 1 hour, however we advise you to leave the mould for 24 hours at room temperature to cure thoroughly.
  14. Once cured, the walls can be gently peeled away and the silicone mould lifted off the original and the base.
  15. The mould material has a shelf life of 12 months if stored in sealed containers at a temperature between 5o -27oC
