Will Polishing Remove White Marks from Resin?

← Back to How do I remove dullness or low shine that has formed on the surface?

White or cloudy marks on resin can be frustrating, especially after all your hard work. Fortunately, polishing can effectively restore clarity if approached correctly—with the right tools and a few practical steps.

Understanding the Cause of White Marks

White or milky marks commonly result from incomplete sanding or using too coarse a grit before polishing. These imperfections scatter light, creating a cloudy appearance on the resin surface. It’s important to recognise that quality surface preparation is key to a flawless finish.

Step-by-Step: Removing White Marks by Polishing

Begin by sanding the affected area with progressively finer sanding pads, such as the Ebonite Abralon Sanding Pads, starting from a coarser grit and working up to a high grit (e.g., 4000). This helps erase deep scratches or haze. After sanding, switch to an appropriate polish—like Epoxy Polish—and apply it using a microfibre cloth or a polishing sponge disc. Polishing sponge discs can further enhance the surface gloss and clarity, especially on epoxy resin. Work steadily and avoid skipping grits in the sanding process to prevent lingering marks.

When This Matters Most

Polishing away white marks is especially important for projects where appearance is everything—such as resin tabletops, artwork, or jewellery. Consistent preparation pays off in professional or gift-quality finishes.
