How Can I Remove Scratches Missed During Polishing?

Even after a thorough polishing session on your resin-coated tile, you may discover stubborn scratches that detract from a flawless gloss. The good news is, these marks can usually be removed with the right approach and a little patience.

Step Back in Grit for Effective Results

If scratches remain after your initial polishing, the key is to return to a coarser sanding grit. Start by identifying the faintest visible scratch and select an abrasive just coarse enough to remove it—often between 800 and 1200 grit on resin surfaces. Work carefully, sanding in a consistent motion until the scratch fades. Once it has disappeared, gradually progress to finer grits in stages, ensuring each step refines the surface further before moving ahead.

Begin with a suitable coarser grit, such as 800 or 1000, depending on scratch depth.
Proceed through finer grits (e.g., 1500, 2000, 3000, up to 4000 for a satin or gloss finish).
Frequently wipe the surface to check progress after each stage.

Polishing to Restore Shine

Once the surface feels even and the previous scratches are gone, it’s time to polish. For resin tiles, a dedicated polish such as “Epoxy Polish” can help restore a mirror-like finish. For best results, use a rotary polisher or hand pad holder to create enough friction for a high-gloss outcome. Apply the polish in circular motions, working it thoroughly until the desired clarity is achieved and any remaining haze has disappeared.
It’s possible to polish by hand with a soft cloth, but mechanical aids will deliver superior uniformity and shine on larger or more visible areas.

When This Matters

Removing missed scratches is crucial when working on display pieces, decorative resin tiles, or any project where a pristine surface is important. Paying attention to these final steps elevates your finish from ‘good enough’ to truly professional.
