How to Achieve a High-Gloss Finish on a Resin Ashtray

How can I achieve a high-gloss finish on my resin ashtray?

A perfectly polished resin ashtray doesn’t just look stunning—it also feels satisfyingly smooth to the touch. Achieving a high-gloss finish is all about careful preparation and the right finishing techniques.

Preparation: Start with a Smooth Surface

Before adding shine, ensure your ashtray is free from rough spots and imperfections. Start by gently sanding sharp edges or uneven areas with fine-grit sandpaper. Progress through increasingly finer grits (such as 800, then 1200) for an ultra-smooth feel. Always sand lightly and in circular motions, taking care not to scratch the entire surface.

Remove sanding dust with a microfibre cloth.
Avoid using coarse abrasives that can leave visible marks.

Methods for a Glossy Finish

There are two effective ways to achieve a glass-like shine. The simplest is to polish the cured resin using a clean microfibre cloth and a small amount of dedicated resin polish or suitable plastic polish. Apply in small circles until the surface gleams. For the ultimate finish, apply a thin top coat of clear resin—such as Art Pro Clear Epoxy Resin—allowing it to self-level for a flawless, high-gloss look. This method also helps to seal in and protect any decorative details beneath.

When a High-Gloss Finish Matters Most

A pristine, glossy finish truly enhances resin ashtrays that feature embedded objects, pigment effects, or transparent colours. The added shine draws attention to decorative details and creates a professional result worthy of display.
