What You’ll Need

• “Ebonite Abralon” – Sanding Pads 360-4000 Grit for Resin and Wood: For fine, even sanding of resin surfaces between stages.
• “Epoxy Polish” – Epoxy Resin Polishing System: Specially formulated polish for transparent or coloured resin, ideal for achieving a brilliant finish.
• “Carbon Polish” – Polishing System for Dark and Black Surfaces, 250ml: Use on dark or black resin pieces for a flawless, non-whitening shine.
• “Heat Pro” – Flexible Heat-Resistant Glossy Coating: Optional final coating for extra heat, scratch, and UV protection.
• Rotary polisher or pad holder (optional but recommended)
• Microfibre cloths, clean workspace, personal protection gear

Step 1: Sand Systematically with Progressive Grit

Begin the finishing process by gently sanding the entire surface of your fully cured resin object. Start with a lower grit—such as 360—using light, steady pressure. Gradually move through finer grits up to 4000, ensuring you remove all previous sanding marks before progressing. Wet sanding can reduce static and keeps the piece cooler, making it ideal for most resin projects. Use circular or linear motions, depending on the object’s shape, and make sure all surfaces are even. “Ebonite Abralon” – Sanding Pads 360-4000 Grit for Resin and Wood are well suited for precise, even sanding throughout this step.

Sand systematically with progressive grit to create a scratch-free, satin foundation for polishing. Avoid skipping grits; this prevents visible scratches and uneven results.

Step 2: Polish to a Mirror-Like Finish

Once sanding is complete and the object is thoroughly dry, it’s time to polish. Apply a small amount of your chosen polishing paste to the resin surface. If your project is transparent or brightly coloured, a resin-specific polish like “Epoxy Polish” – Epoxy Resin Polishing System helps restore brilliant clarity.

For darker or black surfaces, opt for “Carbon Polish” – Polishing System for Dark and Black Surfaces, 250ml to prevent white marks and enhance depth. Work the polish in with a rotary tool or a foam pad holder, using gentle, overlapping motions. Finish by buffing with a clean microfibre cloth, revealing a radiant shine.

Step 3: Apply a Protective Coating if Desired

For resin objects exposed to heat, UV, or regular handling, a protective top coat ensures maximum durability. Mix and apply a specialised clear coating—such as “Heat Pro” – Flexible Heat-Resistant Glossy Coating—to create a resilient, high-gloss finish. Pour or brush on the coating as per instructions, allowing correct time for self-levelling and full cure. This step isn’t always necessary but is highly recommended for functional items like coasters, trays, or art pieces displayed in sunny locations.

Apply a protective coating if desired to shield your creation from scratches, stains, and yellowing.

Finishing Touches: Tips and Mistakes to Avoid

Rushing through sanding steps or skipping grits can leave behind visible scratches. Avoid pressing too hard when sanding, as heat and pressure may damage the resin or distort its shape. Check surface cleanliness before polishing; leftover dust can mar the shine or embed in polish. Work in clean, well-ventilated conditions, and allow coatings to fully cure before handling objects. Maintain a dust-free workspace to prevent debris in your final finish, and always use appropriate personal protection.
