How Do I Remove Deep Gouges in a Resin Sink?

Assessing the Damage

Before starting any repair, closely inspect the gouge. If the damage only affects the surface and does not penetrate too deeply, you may be able to restore the area with progressive sanding and polishing. However, if the gouge is very deep or has compromised the sink’s structure, it is wise to consult a professional for repair or even consider a surface filler appropriate for resin materials.

Sanding and Polishing for Restoration

For surface gouges, start by sanding with a coarse grit pad and progress to finer grits for a smoother finish. The “Ebonite Abralon” sanding pads (available in a range from 360 to 4000 grit) allow you to systematically refine and even out the damaged area. For best results, use the pads with a holder, ensuring consistent pressure and even results, and finish with a fine pad before polishing.

After sanding, apply a dedicated resin polish such as “Epoxy Polish” to restore gloss and blend the repaired area with the rest of the sink. Using a rotary polisher or hand pad holder improves the finish and helps avoid leaving swirl marks or cloudiness.

Practical Tips and When Professional Help Matters

• Clean the area thoroughly before and after repair to remove any dust or residue.
• If the gouge is too deep for polishing alone, consider professional advice to avoid further damage.
• Always test sanding and polishing kits on a hidden area first, especially if your sink is uniquely finished.

This approach is ideal when the damage is less than a few millimetres deep and does not reach the underlying structure. Beyond that, a professional may offer a longer-lasting repair solution.
