What You’ll Need

• “Epoxy Polish” – Epoxy Resin Polishing System: A set designed to restore mirror-like gloss to epoxy resin surfaces.
• “Shiny Shield” – Glossy Release Film for Resin Projects: Ideal for mould lining, enabling a glossy finish after curing.
• Soft, lint-free microfibre cloths
• Polishing pad holder or rotary polisher (for large surfaces)
• High-grit sandpaper (800–3000 grit)
• Clean water and spray bottle
• (optional) Dust mask and gloves for safety

Step 1: Prepare the Workspace and Table Surface

Choose your workspace wisely. Ensure your workspace is clean and free from dust, as airborne particles can become embedded in the resin or finish. Place your table on a flat, stable surface, and if possible, work in a well-ventilated area to avoid build-up of fumes.

Remove any loose dirt, dust or residues from the epoxy surface using a soft cloth. Now inspect the table: if there are any uneven spots or raised drips, gently level them with a sharp blade or high-grit sandpaper. Ensuring no grease or oil remains on the surface is crucial before progressing to sanding or polishing steps.

Step 2: Wet Sand for Smoothness

Clean and sand thoroughly. Start with the coarsest grit (typically 800) and sand the epoxy table’s surface using even, overlapping motions while frequently spraying with water. Maintain gentle pressure to avoid cutting through the resin layer.

Gradually move up through higher grit sandpaper (1200, 1500, up to 3000) to minimise scratches and refine the finish. Be systematic and check the surface regularly for smoothness; every sanding stage reduces visible marks and prepares the surface for polishing.

After completing the sanding steps, wipe the surface clean with a damp, lint-free cloth and let it dry completely before proceeding.

Step 3: Apply and Buff Polishing Compound

Buff to perfection using a quality polishing system specifically designed for epoxy resin. Apply a small amount of “Epoxy Polish” – Epoxy Resin Polishing System to the surface. Use a polishing pad or rotary polisher to work the compound in—start at a low speed and apply light, even pressure.

Use gentle, circular motions. Gradually increase the speed according to the polisher’s instructions, buffing until the surface develops a clear, glossy appearance. If working by hand, a dedicated pad holder greatly improves results and reduces effort compared to using cloths alone. Wipe off residues with a clean microfibre cloth.

Step 4: Maintain a Dust-Free Gloss and Prevention Tips

Prevent dust contamination by keeping the environment clean until the final coat or post-polishing is fully cured. After achieving a glass-like shine, handle your table with care and avoid exposing the finish to abrasive surfaces.

If you plan to cast again or want to achieve a glossy surface during your initial pour, consider lining your mould or table frame with “Shiny Shield” – Glossy Release Film for Resin Projects. This helps produce a flat, mirror-finish surface and eliminates much of the need for sanding or polishing after demoulding.

Troubleshooting and Expert Tips

• Allow adequate curing time for resin before sanding or polishing to avoid smearing.
• Avoid excessive polish or heat, which may cause softening or cloudiness.
• Always use progressively fine abrasives; skipping grits can leave behind scratches that appear after polishing.
• If imperfections remain after buffing, repeat with a finer sanding grit and reapply the polishing compound.
• Never use household glass cleaners as they can dull or damage the epoxy’s glossy surface.
