Silicone Moulds: Easy Release and Clean Use with Epoxy Resin

Silicone moulds are a popular choice for epoxy resin crafts thanks to their flexible, naturally non-stick properties. To ensure consistently easy demoulding and a flawless finish, a little attention to cleanliness and care goes a long way.

Why Silicone Moulds Resist Sticking

Silicone is highly valued in resin work because it is non-porous, flexible, and maintains a smooth internal surface. This means once your epoxy has cured, you can usually remove your castings without force or damage. Flexible silicone moulds, such as the Silicone Hexagons Mould, allow cast pieces to pop out cleanly and rarely require the use of additional release agents for most projects.

The Importance of Keeping Moulds Clean

While silicone naturally minimises sticking, the key to consistent results is keeping your moulds spotless. Dust, leftover resin, or oily residues can interfere with demoulding and mar the finish of your next project. To clean, simply wash your silicone moulds with mild soap and water, rinse thoroughly, and allow to air dry. Avoid harsh chemicals or abrasive scrubbing to maintain the integrity of the non-stick surface.

Extra Tips for Easier Demoulding

For intricate designs or if you notice a mould is starting to lose its non-stick performance, a light application of a specialist release product, such as the Global A2 Release Wax, can help. For flat or unusual shapes, consider lining the base with a glossy release film like Shiny Shield for an ultra-smooth finish and fuss-free release.
