How to Avoid Streaks or Swirl Marks While Polishing Resin

Polishing resin surfaces to a flawless gloss can be tricky, especially when unsightly streaks and swirl marks appear. With the right approach and tools, you can achieve a professional sheen on your resin project—free of distracting patterns.

Choosing the Right Pads and Equipment

Using suitable polishing pads is crucial for an even, mark-free finish. Opt for pads designed specifically for resin, such as the Polishing Sponge Discs 150mm, which are optimised to refine surface gloss. If possible, use a rotary polisher or a compatible pad holder, as these ensure consistent pressure and movement. Clean pads frequently during use to prevent residue from building up, which can otherwise cause streaks.

Method and Technique

For the best outcome, polish using overlapping, even circles. Begin with a high-grit sanding pad, such as the Ebonite Abralon sanding pads, and progress to finer grits until the surface feels smooth. Apply your chosen resin polishing compound, like Epoxy Polish, and continue polishing gently, consistently covering the area for a uniform sheen. Finish with a clean microfibre cloth or polishing sponge for that mirror-like appearance.

When This Matters

If you are restoring a resin bathroom sink or finishing a new resin project where clarity and shine are essential, taking these steps to avoid streaks will make all the difference. Careful polishing ensures your finish is smooth and attractive, whether for bathroom fixtures, worktops, or resin art pieces.
