When it comes to sanding, the grit of the sandpaper is a crucial factor in determining the quality of the finish. With so many different grits available, it can be overwhelming to decide which one to use. In this article, we’ll take a closer look at 600 grit sandpaper and explore its uses, benefits, and limitations.
What is 600 Grit Sandpaper?
600 grit sandpaper is a type of sandpaper that has a medium to fine grit size. The grit size of sandpaper refers to the number of abrasive particles per square inch of sandpaper. The higher the grit size, the finer the abrasive particles and the smoother the finish.
600 grit sandpaper is considered a medium to fine grit size, which means it is suitable for a variety of sanding applications. It is coarse enough to remove small imperfections and smooth out surfaces, but fine enough to produce a high-quality finish.

What is 600 grit sandpaper used for?
600 grit sandpaper is a medium to fine grit sandpaper used for various sanding applications. It is commonly used for sanding down surfaces that have already been sanded with coarser grits, such as 120 or 220 grit. This grit is also used for removing minor scratches and imperfections from surfaces, as well as for preparing surfaces for painting or applying a finish.
In addition to its use in woodworking and furniture making, 600 grit sandpaper is also used in the automotive industry for sanding down metal and fiberglass surfaces. It is also used in drywall finishing to sand down joint compound and create a smooth surface. Overall, 600 grit sandpaper is a versatile tool that can be used for a variety of sanding applications.
Is 600 grit good enough for polishing?
600 grit sandpaper is not typically considered good enough for polishing. While it can be used to remove minor scratches and imperfections from surfaces, it is not fine enough to produce a high-gloss finish. For polishing, a higher grit sandpaper, such as 1200 or 1500 grit, is typically used. These finer grits are able to remove even the smallest scratches and imperfections, leaving a smooth, glossy finish.
However, 600 grit sandpaper can be used as a step in the polishing process. It can be used to remove minor scratches and imperfections before moving on to a higher grit sandpaper for final polishing. In this way, 600 grit sandpaper can be a useful tool in the polishing process, but it is not typically used as the final step.
Can I use 600 grit sandpaper on metal?
Yes, 600 grit sandpaper can be used on metal. In fact, it is a common grit used in the automotive industry for sanding down metal surfaces. 600 grit sandpaper is able to remove minor scratches and imperfections from metal surfaces, leaving a smooth finish. It is also used to prepare metal surfaces for painting or applying a finish.
When using 600 grit sandpaper on metal, it is best to use a sandpaper specifically designed for metal. These sandpapers typically have a more aggressive abrasive and are designed to withstand the rigors of sanding metal. Additionally, it is best to use a sanding block to help keep the sandpaper flat and prevent uneven scratches.
How does 600 grit compare to 800 grit?
600 grit sandpaper is slightly coarser than 800 grit sandpaper. While both grits are considered fine, 600 grit is better suited for removing minor scratches and imperfections, while 800 grit is better suited for final sanding and polishing. 800 grit sandpaper is able to produce a smoother finish than 600 grit, making it a better choice for applications where a high-gloss finish is desired.
In general, 600 grit sandpaper is used for applications where a smooth finish is desired, but a high-gloss finish is not necessary. 800 grit sandpaper, on the other hand, is used for applications where a high-gloss finish is desired, such as in furniture making or automotive finishing.
Can I use 600 grit sandpaper on wood?
Yes, 600 grit sandpaper can be used on wood. In fact, it is a common grit used in woodworking and furniture making. 600 grit sandpaper is able to remove minor scratches and imperfections from wood surfaces, leaving a smooth finish. It is also used to prepare wood surfaces for staining or applying a finish.
When using 600 grit sandpaper on wood, it is best to use a sandpaper specifically designed for wood. These sandpapers typically have a less aggressive abrasive and are designed to prevent scratching the wood. Additionally, it is best to use a sanding block to help keep the sandpaper flat and prevent uneven scratches.
How long does 600 grit sandpaper last?
The lifespan of 600 grit sandpaper can vary depending on the application and the surface being sanded. In general, 600 grit sandpaper can last for several uses, but it will eventually become worn and need to be replaced. The lifespan of the sandpaper can be extended by using a sanding block and by cleaning the sandpaper regularly.
On average, a sheet of 600 grit sandpaper can last for 5-10 uses, depending on the surface being sanded and the amount of pressure applied. However, this can vary depending on the specific application and the quality of the sandpaper. It is best to inspect the sandpaper regularly and replace it when it becomes worn.
Can I use 600 grit sandpaper wet?
Yes, 600 grit sandpaper can be used wet. In fact, using sandpaper wet can help to prevent scratches and improve the overall finish. When using sandpaper wet, it is best to use a sandpaper specifically designed for wet sanding. These sandpapers typically have a more aggressive abrasive and are designed to withstand the water.
When using 600 grit sandpaper wet, it is best to use a lubricant, such as water or a sanding lubricant, to help the sandpaper move smoothly over the surface. This can help to prevent scratches and improve the overall finish. Additionally, it is best to use a sanding block to help keep the sandpaper flat and prevent uneven scratches.
