When crafting bespoke items or prototypes, selecting the right mould material is vital. Silicone putty stands out for its flexibility and broad compatibility—ideal for resin, plaster, and cement casting projects.
Why Silicone Putty is a Flexible Choice
Silicone putty and liquid silicone rubbers are designed to work with a variety of casting media. Whether you are pouring epoxy resins, creating intricate pieces with plaster, or casting decorative objects in cement, silicone putty’s non-stick and adaptable nature helps achieve excellent demoulding and surface detail. Its pliable yet durable structure absorbs fine details, ensuring that your finished piece matches your original design.
Tips for Using with Different Casting Materials
- Resin: Always ensure your silicone mould is fully cured before pouring to avoid any unwanted bonding. Both putty and liquid silicone formulas like I–Gum are specially developed for resin projects, providing crisp details in coasters, jewellery, or art.
- Plaster: Silicone putty reliably holds its shape without sticking or breaking, making it easy to produce repeat casts of fine plaster details.
- Cement: Look for higher-resistance silicones if your projects are larger or demand robustness through multiple uses; options like “Pure Mould” or “Liquid Mould” are suited to frequent cement or concrete casting.
When Cross-Material Compatibility Matters
If you regularly switch between materials such as resin, plaster, and cement, silicone putty’s versatility greatly streamlines your workflow. There’s no need to buy different mould products for each medium; simply ensure you clean the mould thoroughly between uses to preserve detail and extend mould longevity.
