    Total amount

    How much silicone need to fill or make your item/mould/thing.


    You need to figure out how soft (or, for that matter hard) silicone you need in a % of A and B.
    This can be noted as a % of the silicone (A + B) or as a part of the total (as 1A:1B:?D)

    About the math

    You always have 50/50 of A and B.
    Deadener (or Hardener) is in addition to this.
    The calculation finds a ratio, and this ratio is multiplied by the amount of A, B and D.
