Sanding Grit for Drywall: A Comprehensive Guide

When it comes to drywall sanding, the choice of sanding grit is crucial. It can significantly impact the quality of your finish and the overall appearance of your drywall project. In this article, we will delve into the different types of sanding grit available for drywall, their uses, and how to choose the right one for your project.

Understanding Sanding Grit

Sanding grit refers to the abrasive particles used in sandpaper. These particles come in various sizes, which are measured in grit numbers. The lower the grit number, the coarser the sandpaper, and the higher the grit number, the finer the sandpaper.

For drywall sanding, it’s essential to understand the grit range typically used. Most sanding grits for drywall fall between 100 and 220 grit. However, some specialized grits, such as 80 grit, are also used for specific tasks.

Types of Sanding Grit for Drywall

Here’s a breakdown of the different types of sanding grit commonly used for drywall:

Grit Number Description Use
80 Coarse Used for removing heavy imperfections, such as joint compound or paint
100 Medium Used for smoothing out rough spots and preparing the surface for finer grits
120 Fine Used for general sanding and achieving a smooth finish
150 Very Fine Used for final sanding before painting or finishing
180 Super Fine Used for achieving a high-quality, smooth finish
220 Extra Fine Used for final sanding before applying a high-gloss finish

Choosing the Right Sanding Grit

Selecting the appropriate sanding grit depends on several factors, including the condition of your drywall, the type of finish you desire, and the tools you have at your disposal.

For new drywall or surfaces with significant imperfections, start with a coarser grit, such as 80 or 100. This will help remove any rough spots or joint compound. Once the surface is smooth, switch to a finer grit, like 120 or 150, to achieve a more refined finish.
