1. Understanding Sandpaper Grit
Before diving into the different types of sandpaper, it is important to understand the concept of grit. Grit refers to the size of the abrasive particles on the sandpaper. The higher the grit number, the finer the particles and the smoother the finish. Conversely, lower grit numbers indicate coarser particles, which are more suitable for heavy-duty sanding and removing material quickly.
Here are some common grit ranges and their recommended applications:
- Coarse Grit (40-60): Ideal for removing paint, varnish, and rough surfaces.
- Medium Grit (80-120): Suitable for general sanding and smoothing surfaces.
- Fine Grit (150-180): Used for preparing surfaces before painting and achieving a smooth finish.
- Extra Fine Grit (220+): Perfect for final sanding and achieving a polished surface.
