Refining your resin project’s surface begins with progressing through sanding grits. This careful stepwise approach prepares the resin for a polished, glossy finish, removing scratches and imperfections along the way.
Starting Coarse and Working Finer
Begin sanding your cured resin with a coarse grit, such as 360 or 400, to eliminate major defects, bumps, or uneven pours. Gradually move up through finer grits—each step removes scratches left by the previous grit, leaving the surface smoother. Kits like the Ebonite Abralon Sanding Pads offer a range from 360 up to 4000 grit, making it easy to progress incrementally for optimum results.
Techniques for Smoother Finishes
Always sand in circles or lengthwise with light, even pressure to avoid creating gouges. Wet sanding helps reduce dust and yields a more uniform finish—many sanding pads can be used with water for easier cleanup. As you reach finer grits, surface clarity should noticeably improve, providing the ideal base for polishing.
Preparing for Polishing
Once your resin surface is scratch-free and evenly sanded up to a fine grit (typically 2000 or higher), it’s ready for polishing. Apply a specialised resin polish with a microfibre cloth or a rotary buffer for best results—consider tools like the 1200W Polisher or a suitable hand pad holder. Finish with an epoxy-specific polish such as Epoxy Polish for a deep, reflective gloss.
When This Matters
Meticulous grit progression is essential for showpiece resin projects, jewellery, tabletops, or moulded items where clarity and shine are priorities. Rushing the sanding steps or skipping grits can leave visible marks that no polish can fully remove.
