Finish with a Clean Microfibre or Sponge Disc for Polished Resin

To achieve a flawless, glossy surface on Formlabs resin projects, the final finishing step is critical. Finishing with a clean microfibre cloth or sponge disc ensures all fine particles are removed, leaving your work clear and highly polished.

Why Use a Clean Microfibre or Sponge Disc?

After working through sanding grits and initial polishing, residual particles or abrasive dust may still be present on the resin’s surface. A fresh microfibre cloth or a dedicated polishing sponge disc is perfect for gently removing these remnants without introducing scratches or swirl marks. Their soft, non-abrasive texture helps reveal the resin’s true clarity and enhances the final gloss. The Polishing Sponge Discs 150mm are particularly optimised for this stage, providing a consistent and professional finish.

How to Finish Your Resin Project Properly

Ensure the resin surface is thoroughly sanded and polished using appropriate grits and compounds such as those found in the Epoxy Polish System.
Switch to a spotlessly clean, dry microfibre cloth or a polishing sponge disc for the final wipe or buff.
Use light, circular motions to evenly distribute remaining polish and lift any fine debris.
Replace the cloth or disc as soon as any build-up occurs to maintain a scratch-free surface.

This step brings out the ultimate gloss and minimises unwanted residues or streaks.

When This Matters Most

Choosing a clean microfibre or sponge disc is essential when working on transparent or high-gloss resin projects, such as jewellery, art pieces, or tabletop surfaces. It is particularly important for items that will be handled frequently, as even minor streaks or residue can spoil the look and feel of your finished piece.
