Each type of sanding paper has its unique characteristics, and choosing the right one for your project is crucial for achieving the desired results.
Grades of Coarse Sanding Paper
Coarse sanding paper is available in different grades, which indicate the coarseness or fineness of the abrasive particles. The lower the grade number, the coarser the paper. Here’s a breakdown of common grades:
| Grade | Coarseness |
|---|---|
| 60-80 | Coarse |
| 100-120 | Medium-Coarse |
| 150-180 | Medium |
| 220-240 | Fine |
| 320-400 | Very Fine |
When selecting a grade, consider the material you are working with and the level of finish you desire. For instance, a coarse grade is suitable for removing material quickly, while a finer grade is ideal for achieving a smooth finish.
