How do you use release film for epoxy resin?

Preparing and Applying Release Film

To start, ensure your mould or frame is clean and dry for a secure fit. Remove the backing from your release film, such as Shiny Shield, and apply it glossy side up directly onto the mould surface. Take care to smooth it out as you go, pressing gently to prevent bubbles or wrinkles, as these can mark the resin. The self-adhesive backing helps create a bubble-free, mirror-like finish that usually eliminates the need for sanding later.

Pouring Resin and Demoulding

Once your release film is securely applied, pour your epoxy resin as usual. The glossy surface of the film ensures your cured resin will have a professional, highly polished look. After the resin has fully set and cured, gently peel the film away for effortless removal, leaving behind a flawless finish without sticky residue or the need for additional polishing.

When Release Film Makes a Difference

• Complex Shapes: Release film is especially useful for irregular moulds or open-back settings, where standard tapes may not adhere smoothly.
• High-Gloss Results: Use when you want a perfectly flat, shiny surface straight out of the mould.
• Time Saving: Ideal if you wish to minimise post-cure sanding or polishing.
