Is Shiny Shield Release Film Suitable for Silicone Moulds?

How Shiny Shield Works with Silicone Moulds

Shiny Shield is a self-adhesive, reusable film designed to act as a barrier between your casting material and the mould surface. When using silicone moulds, it can be applied to flat areas to achieve a flawless, mirror-gloss finish on the base of your resin pieces. It removes cleanly without leaving sticky residue and can be repositioned or reused for several pours, making it a favourite among resin artists aiming for professional-looking results.

Application Tips for Best Results

• Preparation: Ensure your silicone mould is clean and free from dust.
• Application: Peel away the backing and place the film glossy side up, pressing firmly to create a bubble-free surface. The self-adhesive nature of Shiny Shield makes it easy to secure in place, even on wooden casting frames or within flat silicone mould bases.
• Reuse: Once your resin has set and you’ve removed the piece, you can carefully lift the film and reuse it for your next project.

For intricate or highly flexible moulds, consider alternate or supplementary release agents such as Silicone Oil for Mould Protection and Easy Release – 15ml to ensure full coverage and a smooth release.

When to Choose Shiny Shield Film

Shiny Shield is best used when a high-gloss finish is essential, such as with resin coasters, art panels, or any piece where a perfectly smooth base is desired. It excels for flat surfaces in silicone or homemade frame moulds. For curved, deep, or highly detailed moulds, a liquid release agent may provide better coverage and more reliable demoulding to avoid damaging the work.
