Silicone Putty: Quick and Simple Moulds for Creative Projects

What is Silicone Putty and How Does it Work?

Silicone putty is a two-component, non-toxic mould material. You simply mix equal parts of the two components by hand and work it directly onto the item you wish to copy. Unlike liquid silicones, putty can be applied with minimal mess and does not require elaborate setups or equipment. Within about 20 to 40 minutes, the putty hardens and the mould is ready for use—perfect for one-off or short-run moulding tasks.

When Should You Choose Silicone Putty?

Silicone putty is ideal for creating quick moulds of small objects like jewellery, buttons, decorative trims and even small household items. It’s particularly handy when you want to capture detail fast or need a mould without extensive preparation. The putty’s flexibility also means you can work without gloves, and there’s typically little to no odour.

• Best for single-sided or simple shapes
• No mould release agent usually needed
• Compatible with resin, wax, polyurethane, cement and other craft materials

Tips for Getting Great Results

Always measure thoroughly—use equal volumes of each part for the most reliable set. Knead quickly and evenly to avoid premature curing. Press the putty firmly around your item, ensuring all details are captured. Give the mould 20–40 minutes to set, then carefully demould to enjoy a flexible, reusable shape. For ongoing or larger projects, consider a liquid silicone rubber option instead.
