How to Use Silicone Putty for Fast Casting

Why Choose Silicone Putty?

Silicone putty, such as “I–Gum”, offers straightforward 1:1 mixing of two pastes, meaning you can prepare a mould in just minutes without precise weighing. The material is non-toxic and virtually odourless, enabling direct hand contact and comfortable indoor use. This convenience especially suits beginners or anyone looking for hassle-free mould creation, whether for resin, wax, or cement casting.

How to Use Silicone Putty for Fast Casting

• Pinch off equal parts of the base and catalyst putty.
• Knead together by hand until the mixture is even in colour with no streaks.
• Press the putty around your original item, ensuring all details are covered.
• Allow to set (typically within 20 minutes), then remove the original and your mould is ready for casting.

This process is ideal for coasters, jewellery, small figurines, and decorative pieces. The usability and fast set time let you move from idea to cast within an hour.

When Is Fast-Curing Putty Most Useful?

Rapid-curing, easy-mix silicone putty shines when you need a single or few quick moulds, wish to avoid complex mixing equipment, or are working in environments where low odour and safety are priorities. It can also be useful for testing ideas or for classroom demonstrations where time and simplicity matter.
