Sandpaper is a popular abrasive material that is used to sand various surfaces, including wood, metal, and plastic. It is available in various grits, ranging from coarse to fine, and each grit has a specific purpose. Two of the most common grits used in sandpaper are 80-grit and 120-grit. In this article, we will explore the differences between these two grits and their specific uses.
What is 80-grit sandpaper?
80-grit sandpaper is a coarse sandpaper that has large grit particles on its surface. It is commonly used to remove paint, varnish, and rust from metal surfaces. It is also used to level out rough spots on wood surfaces, such as removing bumps or unevenness.
One of the key advantages of using 80-grit sandpaper is that it removes material quickly. However, it can leave behind scratches and rough spots on the surface being sanded. Therefore, it is important to use finer grits of sandpaper to remove these scratches and achieve a smooth finish.
What is 120-grit sandpaper?
120-grit sandpaper is a medium-grit sandpaper that has smaller grit particles on its surface than 80-grit sandpaper. It is commonly used to smooth out rough spots left behind by 80-grit sandpaper or to prepare a surface for a finishing coat, such as paint or varnish.
One of the key advantages of using 120-grit sandpaper is that it removes material at a slower rate than 80-grit sandpaper. This allows for more precise sanding and reduces the risk of leaving behind scratches or rough spots on the surface being sanded.

What is the difference between 80-grit and 120-grit sandpaper?
The primary difference between 80-grit and 120-grit sandpaper is the size of the grit particles on their surface. 80-grit sandpaper has larger grit particles, while 120-grit sandpaper has smaller particles. This results in 80-grit sandpaper being more aggressive and removing material faster than 120-grit sandpaper.
When should you use 80-grit sandpaper?
80-grit sandpaper is best used for removing material quickly and efficiently, such as when removing paint, varnish, or rust from metal surfaces. It is also effective at leveling out rough spots on wood surfaces, such as removing bumps or unevenness. However, it is important to follow up with finer grits of sandpaper to achieve a smooth finish.
When should you use 120-grit sandpaper?
120-grit sandpaper is best used for smoothing out rough spots left behind by 80-grit sandpaper or for preparing a surface for a finishing coat, such as paint or varnish. It is also effective at removing small imperfections on wood surfaces, such as small scratches or marks. Using 120-grit sandpaper before a finishing coat will ensure a smooth and even surface.
In conclusion, the main difference between 80-grit and 120-grit sandpaper is the size of the grit particles on their surface. 80-grit sandpaper is more aggressive and removes material faster, while 120-grit sandpaper is less aggressive and removes material at a slower rate. Knowing when to use each grit will help you achieve a smooth and even finish on your sanding project.
