The most common sanding tasks for drywall include smoothing joint compounds, removing imperfections, and preparing the surface for painting. Knowing what grit sandpaper to use is key to avoiding damage while achieving a smooth surface.
Types of Sandpaper Grits for Drywall

Medium Grit (100-150):
Medium-grit sandpaper is excellent for smoothing joint compounds after they dry. It’s the go-to option for leveling minor imperfections while preventing over-sanding. If you’re asking yourself what grit sandpaper for drywall you need for general smoothing, medium grit is a safe and effective choice.
Fine Grit (180-220):
Fine-grit sandpaper is the best choice for finishing drywall. It helps achieve a smooth surface that’s ready for primer and paint. Fine grit is your answer if you’re asking what grit sandpaper for drywall is ideal for final touches, fine grit is the answer. It leaves behind a polished surface that ensures a high-quality result when painting.
