How to Get Rid of Cloudiness or Haze in Polished Resin

If your once-glossy resin piece develops a cloudy or hazy appearance after polishing, don’t worry—this is a common issue that can be corrected with the right technique and tools. Read on for practical steps to restore a crystal-clear finish.

Understanding Cloudiness After Polishing

Cloudiness or haze in polished resin is often caused by tiny scratches left behind from insufficient sanding or using an unsuitable polish. Sometimes, if the polishing compound isn’t thoroughly worked into the surface or not buffed properly, a dull film can remain. Ensuring each stage, from sanding to final polish, is thorough is key to achieving a truly clear result.

Step-by-Step Method to Remove Haze

Return to Sanding: Start with a high-grit abrasive pad and gently sand the affected area, gradually moving to finer grits (such as 1200 or 2000 grit).
Polishing: Use a polishing compound formulated for clear resin, like the “Epoxy Polish” – Epoxy Resin Polishing System. This can be applied by hand with a microfibre pad, but for best results, use a suitable pad holder or a rotary polisher to evenly buff out micro-scratches and restore lustre.
Buff to Finish: Ensure the polish is worked in thoroughly and continue buffing until the surface regains its clarity. Wipe away any residue with a clean, soft cloth.

When This Matters

This remedial process is essential for projects where optical clarity or a high-gloss finish is the main feature—such as art pieces, resin countertops, or jewellery. For dark resin pieces, a specialised polish for black surfaces might be needed.
