Create your own coasters and round stands with this silicone mould. This quality mould is very strong, flexible and reusable. It is resistant to frost and high temperatures (-40°C to 240°C), it is also non-deformable and allows easy removal from the mould. This mould is suitable for casting materials such as creative concrete, Raysin, or casting resin. Tips for use: If the casting material used is a heavy material such as creative concrete, it is recommended to place the mould on sand during casting and curing so that the spaces are stabilised from below and the bottom does not become wavy. You will also find everything you need to create your concrete or resin supports, such as our creative concrete bags and pots, pigments, and silicone or hard plastic moulds.
