How to Achieve a High-Gloss Resin Finish Without Sanding

← Back to What doesn’t epoxy resin stick to?

Tired of endless sanding and polishing when finishing your resin projects? Using a glossy release film is an effortless way to achieve a brilliant, professional finish straight from the mould.

Why Consider Release Film for High-Gloss Finishes?

Glossy release film acts as a barrier between your resin and the mould, creating a perfectly smooth surface. This prevents the resin from fully bonding to the mould itself, which means you can demould with ease and reveal an impressively polished finish—no laborious handwork required.

Mirror-like result: The film’s slick surface imparts a high-gloss effect, eliminating the need for sanding or buffing.
Time-saver: Bypass additional finishing steps and achieve your desired look immediately after curing.

How to Use Glossy Release Film Correctly

To get the best finish, start by removing the protective backing from your chosen release film, such as the Shiny Shield film. Lay it, glossy side up, onto your mould or frame and smooth out any air bubbles for a seamless application. Pour your resin onto the prepared surface. Once set, the film peels away cleanly, leaving a brilliant shine on your cured piece. The film can typically be reused, making it a practical addition for multiple projects.

When This Matters Most

Using glossy release film is especially valuable for large resin surfaces or decorative projects where uniform sheen and minimal hand finishing are essential, such as tabletops, coasters, and jewellery pieces. It’s also ideal if you’re seeking to speed up production or reduce manual labour in your workflow.
