Can I Polish Sanded Resin by Hand or Machine?

← Back to How do you polish sanded resin?

Polishing sanded resin brings out its natural clarity and shine, but choosing between hand or machine polishing can make a big difference to your project. Here’s what to consider to get the best results.

Hand Polishing: Best for Detail and Small Projects

Hand polishing is well-suited to small resin pieces, intricate jewellery, or delicate areas where precision is key. Using a polishing system like Epoxy Polish and a dedicated hand pad holder provides better control and prevents overworking the surface. For a smooth, glossy finish, start with finer grit sanding pads, then apply the polish with gentle, circular movements using a microfibre cloth or sponge. Although it’s more time-intensive, hand polishing allows you to focus on fine details without risking surface damage.

Machine Polishing: Fast, Consistent Results

For larger resin surfaces—such as tabletops or art panels—a polishing machine offers speed and even results. A variable speed polisher with a sturdy handle is ideal for maintaining control while reducing fatigue. Combining a rotary polisher with a resin-specific polish ensures that you can quickly remove micro-scratches and restore a brilliant sheen. Use progressively finer grits, finishing with a polishing pad to enhance the gloss. Machine polishing is particularly useful when consistency and efficiency are needed.

Choosing Tools and Accessories

• Sanding Pads: Start with coarser pads (such as Ebonite Abralon) and progress to finer grits for smooth preparation.
• Polishing Compounds: Use dedicated resin polishes designed to deliver a high-gloss, swirl-free finish.
• Application Tools: Use pad holders for manual work and polishing pads or sponges for machines for best results.

Always follow product instructions and test on a small area if unsure.

When This Matters

If the resin piece requires a flawless finish or will be closely inspected, such as in jewellery, artwork, or furniture, choosing the right polishing technique ensures a professional result.
