Sand Using Gradual Grits, Then Polish: Resin Coffee Table Finishing Guide

For a resin coffee table to truly shine, the finishing process makes all the difference. Gradual sanding followed by thorough polishing is essential for achieving a flawless, glass-like surface.

Step-by-Step: Sanding Gradually for Smoothness

Start sanding your fully cured resin surface with a coarse grit (360 or 500), gently moving in circular motions. Progress through finer grits: 1000, 2000, 3000, finishing at 4000. Make sure the table is dry and clean between each step to avoid scratching from leftover particles. This staged approach removes imperfections, evens out the surface, and prepares the resin for polishing.

For best results, use a sanding pad or orbital sander with appropriate sanding discs. Wet sanding—using water or a bit of soapy water—can help reduce dust and achieve a smoother finish. Take your time, especially at the higher grits, as this ensures the most even result before polishing.

Polishing Your Resin Coffee Table

Once sanding is complete, it’s time to polish. Use a polishing cream specifically designed for resin (such as the one included in the “River-Table” – Complete Kit) and clean polishing pads. Apply the cream with a soft pad, working in small sections using gentle pressure until the surface begins to shine. Buff away residue with a microfibre cloth for a gleaming, professional finish.

Use fresh pads for the final polish step to avoid streaks.
Check under natural light to ensure even gloss and clarity.

When Attention to Finish Matters Most

A meticulous sanding and polishing routine is especially important if your coffee table will be a centrepiece in your living room. Every detail is more visible on a clear resin surface, so gradual grits and careful polishing help achieve that remarkable showroom look.
