In this video, I show you how I work my RTV2 3D silicone addition mould. I'll show you how to make silicone molds that will save you money. At the end of the video, you'll have a silicone mold for the foot I place my Easter Eggs on.
It takes at least 2 days of work for a 3D mold and a lot of patience but the result, is worth all the effort.
Materials used:
- RTV 2 additive silicone, bicomponent and marble dust you can find here
www.piatra-lichida.ro/
- Thixo, thickening agent for silicone
- Modelling clay, for the bed of the shape I work the mould from
- Remodelling plaster for the walls before casting (if you can find plaster that does not contain sulphur you can remove the modelling clay and work only with sulphur-free remodelling plaster)
- Building plaster (or modelling plaster)
- Universal Vaseline
- Silicone spray
It is recommended to have a machine that extracts the air from both the silicone and the marble dust, this way we eliminate air bubbles that can make the casting result less than perfect, but I showed you in the video that any imperfection can be fixed.
