What grit to sand epoxy resin?



Choosing the Ideal Grit for Epoxy Resin Finishing

To achieve a perfect finish on RESINPRO resin, it is crucial to select the right grit for the job. The grit size will influence the surface roughness and, consequently, the final result. It is recommended to start with a coarser grit, such as 80 grit, to remove any imperfections and level the surface. Subsequently, you can move to a finer grit, like 120 grit, to achieve a smooth and polished surface.

Polishing Techniques for Epoxy Resin

There are several effective techniques for polishing resin. A common technique is to use an orbital sander with fine-grit sandpaper. Alternatively, manual sanding can be done by wrapping sandpaper around a wooden block to ensure even pressure on the surface. It is important to work with regular and consistent movements to avoid unevenness and achieve a uniform result.

Surface Preparation and Cleaning

Before starting the sanding process, adequate preparation of the resin surface is essential. Ensure that the resin is fully cured and dry before beginning. Remove any residues or impurities from the surface and ensure it is clean and free of dust. Use a damp cloth to clean the surface and remove any traces of dirt or grease that could compromise the final result.

Finishing and Polishing

Once the resin sanding is complete, you can proceed with finishing and polishing the surface. Use abrasive paste to eliminate any remaining scratches and achieve a flawless finish. Subsequently, apply a specific resin polish to add shine and protection to the surface. With care and precision, a professional and high-quality result can be achieved.
