What Happens If You Skip Polishing When Sanding Resin?

Skipping Polishing: Should You Omit the Final Step in Resin Sanding?

When sanding resin, many wonder if polishing is an absolute necessity or just an optional upgrade. Skipping the polishing stage can have a significant impact on your finished result, especially if you’re aiming for a clear, glossy surface. Here’s what you need to consider.

What to Expect If You Skip Polishing

Sanding removes surface imperfections, but even when progressing through finer grits, microscopic scratches tend to remain. If you stop at sanding and do not polish, resin surfaces typically appear cloudy or matte. This is due to the light scattering on the tiny scratches left behind. Sanding pads such as the “Ebonite Abralon” – Sanding Pads can produce a smooth finish, but polishing is required for true clarity.

When Skipping Polishing Might (or Might Not) Matter

Matte projects: For objects where a satin or frosted look is desired, skipping polishing may save time and effort.
Functional surfaces: If clarity or shine are not important (for example, hidden or utility parts), sanding alone may suffice.
High-gloss finishes: Decorative items, jewellery, and table-tops almost always benefit from a final polish for that professional, glass-like look. In these cases, omitting the polish step will result in a flat appearance that can detract from the overall result.

How to Achieve a Polished Resin Finish

If you want a truly glossy result, use a resin-specific polishing compound after sanding. A pad holder or rotary polisher provides even pressure and friction, making it easier to buff out remaining scratches. Products like the “Epoxy Polish” – Epoxy Resin Polishing System work well for restoring clarity and depth to the finished piece. For best results, always ensure surfaces are clean and dry before polishing, and work gradually from coarse to fine abrasives before moving on to polish.
