Best Sandpaper for Drywall Sanding: A Comprehensive Guide
When it comes to drywall sanding, choosing the right sandpaper is crucial for achieving a smooth, professional finish. The right sandpaper can make the difference between a job that looks polished and one that looks amateurish. In this guide, we’ll explore the best sandpaper options for drywall sanding, considering factors like grit size, material, and application.
Understanding Grit Size
The grit size of sandpaper determines how coarse or fine the paper is. A lower grit number indicates a coarser paper, which is better for removing material quickly, while a higher grit number indicates a finer paper, which is better for smoothing out surfaces.
| Grit Size | Description |
|---|---|
| 40-60 | Coarse grit, ideal for removing paint or heavy imperfections. |
| 80-120 | Medium grit, great for smoothing out surfaces and removing minor imperfections. |
| 150-220 | Fine grit, perfect for achieving a smooth finish and preparing surfaces for painting. |
| 240-320 | Very fine grit, ideal for final sanding before painting or varnishing. |
