How to Prevent Swirl Marks When Polishing Resin

← Back to How to polish two-component resin

Swirl marks and streaks are common frustrations when polishing resin, especially if you want a flawless, professional finish. Fortunately, with careful technique and the right materials, you can achieve a clean, high-gloss result every time.

Essential Polishing Steps to Avoid Swirls

To reduce the risk of swirl marks, begin by ensuring your surface is properly sanded using high-quality pads, such as the Ebonite Abralon Sanding Pads, progressing through finer grits. Always use a clean, soft pad for each polishing stage and change pads whenever you switch to a finer compound. Applying even, gentle pressure—whether by hand or with an appropriate polisher—helps create an even finish and prevents micro-scratches that can develop into visible swirls.

Choosing the Right Compounds and Tools

Select a polishing compound designed for epoxy resin, ideally one labelled as anti-hologram or formulated to prevent swirl marks. Products like the Epoxy Polish – Epoxy Resin Polishing System are made to deliver a brilliant gloss and reduce hologramming. For dark or black resin projects, consider a specialist product such as Carbon Polish, which leaves no visible white residue. Using a rotary polisher or pad holder, rather than a cloth alone, ensures more uniform results and reduces streaking.

When Attention to Technique Matters Most

Swirl marks are especially visible on large, flat surfaces and glossy finishes, such as resin tables or art pieces. For projects meant to be displayed or sold, taking extra care at every stage—from sanding to final buffing—makes a significant difference to the outcome and perceived quality of your work.
