Hi.
Im looking to remould the plug from my 2 part mould after destroying the original using this casting resin. Problem is (unless im blind) I cant see where it says how much 2kg will fill in volume ? Also it possible to thicken the resin during application as pretty sure if the viscosity is too low it will just flow between the gaps. Finally, should I wax and release agent the moulds before casting ?
Thanks

A hint for getting apart moulds when you use silicones is either slide a slim butter knife type blade to cut the silicone, or if you have access some fishing wire or trap setting wire can be used to cut the silicone abit like using a cheese wire. Just remember use a small dowel of wood each end of the wire so you have something to pull on without the wire digging in your fingers.
Once seperated, you can usually then lift one end of the silicone remaining and peel it off fairly easily.
