Q
what grade sandpaper for resin
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
When working with resin, selecting the right grade of sandpaper is crucial for achieving a smooth finish. Typically, you'll want to start with a lower grit sandpaper to remove any imperfections or excess resin and then move up to higher grits for a finer finish. For initial sanding, use 120-180 grit sandpaper. This will help you quickly remove any bumps or ridges without spending too much time on the initial stages. Once the major imperfections have been addressed, switch to a 320-grit sandpaper. This finer sandpaper will smooth out the surface further and prepare the resin for the final sanding steps. To achieve an ultra-smooth surface that's ready for polishing, use 600-1200 grit wet sandpaper. Wet sanding with these finer grits can give you a glass-like finish, especially when working with clear resins. Remember to always wear protective gear such as gloves and a mask when sanding resin, as the dust can be harmful. Also, ensure the resin has fully cured before sanding to avoid damaging the surface.
