How to Demould Safely with I-Gum Silicone Putty

← Back to how to make a silicone rubber mould video

When your silicone mould has fully cured, demoulding is the final step to reveal your cast object. It’s important to remove pieces safely, preserving both the mould detail and the finished cast.

The Best Way to Demould with I-Gum

Begin by gently releasing the edges of the mould. Flex the silicone outwards, peeling it back from the cast piece. Work slowly and support areas of fine detail to avoid any risk of stretching or tearing the mould. Using your fingers rather than tools helps maintain greater control and reduces the likelihood of damage.

Practical Tips for Safe Demoulding

Ensure the silicone mould has cured fully—typically after several hours or as instructed.
If the object has deep undercuts, flex the mould gradually and ease the object free instead of applying force.
For intricate casts, move in small sections rather than trying to remove the whole piece at once.

“I–Gum” silicone putty is non-stick, so demoulding typically doesn’t require any release agent. Avoid using sharp implements which may damage fine features in either the mould or the object.

When Safe Demoulding Matters Most

Extra care is crucial when you plan to reuse your mould for multiple casts, or when working with delicate shapes. Following a gentle approach helps your “I–Gum” mould last longer and continue producing accurate results.
