Embarking on a drywall sanding project? The first step towards a smooth, professional finish is selecting the right grit for your sanding screen. This guide will walk you through the grit selection process, ensuring you achieve the best results for your drywall sanding needs.
Understanding Drywall Sanding Grits
Drywall sanding grits range from coarse to fine, typically spanning from 60 to 220 grit. Each grit size serves a specific purpose in the sanding process. Understanding these grits is key to choosing the right one for your project.
Coarse Grits (60-80)
- 60 Grit: Ideal for initial sanding on new drywall, removing heavy texture and imperfections.
- 80 Grit: Suitable for light sanding after joint compound application, smoothing out minor imperfections.
Medium Grits (100-120)
- 100 Grit: Great for light sanding between coats of joint compound, removing fine imperfections.
- 120 Grit: Perfect for final sanding before painting, providing a smooth surface for paint adhesion.
Fine Grits (150-220)
- 150 Grit: Ideal for light sanding between coats of paint, removing fine scratches and dust nibs.
- 180 Grit: Suitable for final sanding before applying a stain or clear coat, providing an ultra-smooth surface.
- 220 Grit: Reserved for professional touch-ups and fine sanding, ensuring a flawless finish.
Selecting the Right Grit for Your Project
Choosing the right grit depends on the stage of your drywall project and the desired finish. Here's a simple guide to help you:

| Project Stage | Recommended Grit |
|---|---|
| Initial sanding on new drywall | 60 or 80 grit |
| Sanding between joint compound coats | 100 or 120 grit |
| Final sanding before painting | 120 grit |
| Light sanding between paint coats | 150 grit |
| Final sanding before stain or clear coat | 180 or 220 grit |
Remember, it's essential to start with a coarse grit and progress to finer grits for the best results. Skipping grits can lead to visible scratches and an uneven finish.
