What are the different types of sandpaper and when should you use them?

Sandpaper is an essential tool for any DIY or home improvement project that involves sanding. There are several different types of sandpaper available, and choosing the right one can make all the difference in achieving a smooth and even finish.

Types of Sandpaper

• Garnet sandpaper: Made of natural minerals, it is a good all-purpose abrasive that is great for sanding wood. It is relatively inexpensive and produces a fine finish.
• Aluminum oxide sandpaper: Synthetic and durable, it is a good choice for sanding metal, painted surfaces, and fiberglass. It is also suitable for woodworking projects and produces a smooth finish.
• Silicon carbide sandpaper: Extremely hard and sharp, it is a good choice for sanding hard materials such as stone, glass, or metal. It is also suitable for wet sanding.
• Zirconia alumina sandpaper: Extremely durable, it is suitable for heavy-duty sanding jobs such as removing paint and rust from metal surfaces.
