When working with epoxy resin, lining your mould is crucial to guarantee your project can be removed easily and with a flawless finish. Overlooking this essential step is often the reason behind sticky, stubborn resin projects.
Why Lining Moulds Is Essential
Epoxy resin can powerfully adhere to many common casting materials, making removal difficult and potentially damaging your project or mould. Using a dedicated liner or a non-stick mould surface is key for a clean demould every time. Products like professional-grade release films or high-quality silicone moulds create a barrier, stopping the resin from bonding to the frame or base.
Recommended Products and How to Use Them
- Glossy release film: Self-adhesive films such as the “Shiny Shield” are applied glossy side up to your mould or frame. Lay it flat, pour in the resin, and once cured, peel the film away for effortless release and a mirror-like finish.
- Non-stick silicone moulds: For intricate objects, reusable silicone moulds like the “Three Drops” jewellery mould provide an inherently non-stick surface, making them easy to use and ideal for smaller, detailed pieces.
Always ensure your liner is bubble-free and well applied, and avoid leaving your resin in the mould beyond recommended times to reduce localised sticking.
When This Matters Most
Lining your mould is especially important when a high-gloss, scratch-free finish is desired, or when working with formwork you wish to reuse. It prevents unnecessary sanding and reduces the chance of breaking delicate projects during demoulding.
