What You’ll Need

• “Ebonite Abralon” – Sanding Pads 360-4000 Grit for Resin and Wood – for gradual, controlled sanding
• 1200W Polisher for Sanding and Buffing – Variable Speed, D-Handle – for efficient, even polishing on larger pieces
• “Epoxy Polish” – Epoxy Resin Polishing System – for a glossy, professional-grade finish
• “Carbon Polish” – Polishing System for Dark and Black Surfaces, 250ml – for dark-toned resin to avoid white residue
• Clean microfibre cloths, water spray bottle, and protective gloves

Step 1: Sand Your Resin Surface Evenly

Start by ensuring the resin object is fully cured and free from dust or debris. Begin sanding using a coarse grit sanding pad (around 360 grit) to remove surface imperfections, marks, or unevenness. Sand in a circular motion, keeping steady but gentle pressure for a uniform finish.

Progress through finer grits (600, 1000, 2000 and up to 4000 as needed) to gradually refine the surface and remove scratches from the previous step. Wet sanding is strongly recommended at higher grits: spray a little water on the surface and the pad before moving to a finer grit. Wet sanding prevents scratches during the refining stages and helps to avoid heat build-up.

Do not rush grit progression with sanding pads. Failure to eliminate scratches at each stage can leave visible marks under the final polish.

Step 2: Select and Apply the Appropriate Polishing Cream

Once your resin surface is smooth and lightly matte, it’s time to apply polishing cream. For most standard or clear resin finishes, use a soft cloth or polishing pad with a dedicated formula like “Epoxy Polish” – Epoxy Resin Polishing System to remove haze and increase gloss.

If your project involves dark or black resin, opt for “Carbon Polish” – Polishing System for Dark and Black Surfaces, 250ml, which is designed to brighten these tones without leaving white streaks or residue.

Apply a small amount of cream to the pad or microfibre cloth and polish in small, circular motions. Cover the entire surface systematically. For deep scratches that persist through hand buffing, a motorised tool will help achieve perfect clarity.

Step 3: Buff Using Appropriate Tools for a Mirror Shine

For large or flat resin surfaces, use a dedicated machine such as the 1200W Polisher for Sanding and Buffing – Variable Speed, D-Handle to deliver an even, swirl-free gloss. Keep the tool moving steadily and do not apply excessive pressure – let the polish and the pad do the work.

With smaller or detailed objects, buff gently using a handheld pad or microfibre cloth, ensuring you reach all angles and corners. Always remove excess polish between applications with a clean, dry cloth to prevent streaking and build-up.

Repeat polishing and buffing steps as needed until the desired level of shine is achieved. Conduct a final visual check in bright light to spot missed areas.

Tips, Mistakes, and Troubleshooting

Allow sufficient curing time for resin before polishing to avoid sticky or cloudy results. Choose products suitable for dark or coloured resin to avoid unwanted residue on tinted projects. Test products on an inconspicuous area first if you’re unsure.

If surface dullness or haze remains after polishing, check if you skipped a sanding grit. Always use clean pads and cloths to prevent introducing fresh marks. For persistent scratches, step back to the previous grit and repeat the process carefully before re-polishing.

Remember to work in a dust-free, well-ventilated area and wear protective gloves and a mask if sanding or polishing for extended periods.
