1. Add 50g of algenate powder for every 100ml of water and mix into a paste creating no air bubbles.
2. Slop it onto the object you are casting leaving no thin areas or gaps.
3. Once applied thoroughly, leave to dry and become bouncy
4.Once bouncy cover in modrock, doubling over at the edges so they are strong enough to pull at without tearing then leave to dry.
5. When dry, pull of both mod-rock and algenate from the object.
6. Once removed, close over any gaps so that when laid flat with plaster it won't pour out.
7. Fill with plaster and tap till any air bubbles come out.
8. Leave to dry, then remove modrock then algenate. Algenate might need to be torn off.
