How should I store silicone moulds for repeated use?

← Back to how to create a resin mould for polyurethane

Properly storing your silicone moulds is key to ensuring they remain flexible and last for repeat casting projects. With simple steps, you can keep your moulds in excellent condition for future use.

Best Practices for Storing Silicone Moulds

Store silicone moulds flat in a cool, dry place. Avoid stacking heavy objects on top as this can distort their shape. Keep them away from direct sunlight, which may cause the silicone to degrade or become brittle over time. Thoroughly clean and dry each mould before storing it, as moisture or resin residue can affect performance or encourage mould growth.

Caring for Your Moulds Between Uses

Gently rinse your moulds with mild soap and water after use, pat them dry, and let them air out fully before putting them away. For intricate or professional-grade moulds, like “Pure Mould” silicone rubber, using a soft brush ensures any small crevices are clean. Lightly dusting the inside with talcum powder before storage can also help maintain flexibility.

When Careful Storage Matters Most

• If you use your silicone moulds for detailed casting or with polyurethane resins, careful storage prevents warping and shrinking, helping preserve fine details.
• Frequent reuse or long gaps between uses make correct storage even more important for consistent results.
