Mixing: Combine equal amounts of parts A and B until colour is uniform. This ensures optimal setting and mould strength. Application: Quickly press the putty around your item—working time is usually up to 20 minutes, so plan ahead. Demoulding: Once set, gently remove both the putty and original. The mould is now ready for resin, wax, or similar materials. For detail-critical or translucent tasks, you might consider liquid silicone rubbers such as Pure Mould , but for speed and simplicity, silicone putty is hard to beat.

Can I Use Silicone Putty for Small Moulds?

Silicone putty is a popular solution when you want to make small or quick moulds by hand. Whether you need to mould intricate resin jewellery or carry out repairs, it’s worth understanding the benefits and limitations of using putty for your project.

Why Choose Silicone Putty for Small Moulds?

Silicone putty stands out for its hands-on ease and speed. The pliable, two-component material is simply mixed in equal parts (1:1 ratio) and pressed around your master item, making it perfect for rapid prototyping, simple craft projects, or on-the-spot fixes. Its non-toxic formula, such as found in I–Gum Silicone Putty, allows you to work without gloves and produces minimal odour, making it especially practical for home or small studio use.
