How much silicone do I need to complete my mould?
You need to work out the volume of your mould - length x Breadth x height
This can then be used to work out the weight of material needed.
The formula for this is Mass = Density x Volume
The density can be found on the technical data sheet (SG)
So if you have 100cm x 50cm x 1.5cm = 7,500 cm3
7500 x 1.2 = 9,000g which is 9 kilos - so this would be the amount to mix + allowances for waste in mixing and pouring - around 10%
