If you're finishing drywall, sanding is an essential part of the process to achieve a smooth, even surface. But with so many different grits of sandpaper available, it can be difficult to know which one to use. In this article, we'll explore what grit of sandpaper is best for sanding drywall.
When sanding drywall, it's recommended to start with a coarse grit sandpaper such as 100 or 120 grit. This will help to remove any high spots, bumps, or ridges left over from the installation process. Coarse grit sandpaper is also useful for smoothing out rough areas around seams or joints in the drywall.
After the initial sanding is complete, a finer grit sandpaper should be used to further smooth the surface of the drywall. Medium grit sandpaper such as 150 or 180 grit is ideal for this step. This grit will help to blend the rougher areas with the surrounding surface, creating a more even finish.
Finally, a very fine grit sandpaper such as 220 grit can be used for the final sanding. This grit will help to remove any remaining imperfections and create a smooth, polished surface that is ready for painting or wallpapering.
It's important to note that when sanding drywall, it's recommended to use a sanding screen or mesh rather than traditional sandpaper. Sanding screens are more durable and effective at removing the rough spots and bumps on drywall surfaces.
In conclusion, the best grit of sandpaper for drywall is a coarse grit such as 100 or 120 grit for initial sanding, followed by a medium grit such as 150 or 180 grit for further smoothing. Finally, a very fine grit such as 220 grit can be used for the final sanding. It's recommended to use a sanding screen or mesh for sanding drywall to achieve the best results.
