There are various sizes of 3000 grit sandpaper that you can use for various wood finishing purposes. Many sizes of sand are used in making sandpaper.
The basic principle of using the best 3000 grit sandpaper is that all sanding must be done with grain. Never make circular, rough, or oblique strokes with sandpaper, as it will always occur. The final wood grain needs to be sanded.

Careful examination of the wooden structure with a magnifying glass shows that the fibers are arranged like parallel tubes along the grain. These fibers are scratched, torn, or cut by a sharp edge of sand if the blow is directed in a direction other than the length of the grain.
If you react well to the nipples, you cannot easily get rid of scratches. Such injuries need to be scraped off, and once all the scratches are gone, the surface needs to be sanded by sliding the sandpaper along the grain of the wood with a suitable tool.
3000 grit sandpaper holding blocks are used in each finishing chamber to provide more pressure. The size, weight, and coverage of the blocks depend on the type of work being performed. For large areas, sizable heavy blocks have several advantages.
