Sandpaper comes in various grits, and each grit is suitable for different purposes. The grit refers to the number of abrasive particles per square inch of sandpaper. A higher number indicates a finer grit and a lower number indicates a coarser grit. One common grit level is 120, and it's frequently used for different projects.
What is 120-grit sandpaper used for?
120-grit sandpaper is a medium grit that can remove material quickly while also providing a smooth surface. It is commonly used for sanding down rough surfaces, smoothing out edges, and preparing surfaces for painting or staining. It can also be used for finishing work on metal, plastic, or wood surfaces. 120-grit sandpaper is ideal for sanding rough spots, and removing small burrs, and rust. It is also used to remove old finishes or paint from a surface.
When sanding with 120-grit sandpaper, it's essential to ensure that the surface is clean and dry before you begin sanding. Always wear a mask to protect your lungs and safety goggles to shield your eyes from dust and debris. It's also essential to sand in the direction of the wood grain or the surface's direction to avoid leaving scratch marks.
Another application of 120-grit sandpaper is for sanding between coats of paint or stain. Sanding between coats can help to ensure a smooth and even finish. It removes any bumps, dust particles, or rough spots that may have formed during the previous application. For this purpose, it's best to use a sanding block or sponge to ensure even pressure is applied.
In summary, a 120-grit sandpaper is a versatile medium grit that can be used for various purposes. It can quickly remove material while providing a smooth surface. It is commonly used for sanding down rough surfaces, smoothing out edges, and preparing surfaces for painting or staining. It is also ideal for sanding between coats of paint or stain to ensure a smooth and even finish. When using 120-grit sandpaper, it's crucial to wear proper protective gear and sand in the direction of the wood grain or surface to avoid leaving scratch marks.
