Can I Use Liquid Silicone for Resin Moulds?

Why Choose Liquid Silicone for Resin Moulds?

Liquid silicone is a top choice for making resin moulds because it can capture intricate patterns and difficult undercuts, producing results not always possible with ready-made moulds. Its fluidity makes it ideal for custom shapes—think jewellery, art pieces, or objects with complex forms.

Products like “Pure Mould” – Translucent Liquid Silicone Rubber for Mould Making offer an easy 1:1 mixing ratio and a fast curing time, providing excellent detail with less shrinkage over time and multiple uses.

Basic Steps for Making a Silicone Mould

• Measure and mix the liquid silicone according to the manufacturer’s instructions, ensuring the ratio is accurate for proper curing.
• Pour the silicone slowly over your model, making sure it covers all details and avoids air bubbles.
• Allow to cure fully—many products set within several hours, but always double-check the guidelines for your silicone.
• Once firm, carefully demould your item. The resulting silicone mould can then be used to cast your resin object multiple times.

When Liquid Silicone is Especially Useful

Liquid silicone is particularly handy for bespoke resin projects or objects with elaborate shapes and textures, where off-the-shelf moulds simply won’t suffice. Artists and crafters looking to perfectly replicate original pieces, prototypes, or small, detailed items benefit most from making their own silicone moulds.
