When sanding wood, you should move the sandpaper in which direction?

When sanding wood, it's important to move the sandpaper with the grain. This technique helps achieve a smoother finish on the wood surface. The grain of the wood consists of fibers that run in a particular direction; sanding in the same direction as the grain ensures that you are not tearing or damaging these fibers. Sanding with the grain minimizes scratches and other imperfections, leading to a more aesthetically pleasing final product. Additionally, it allows for better absorption of finishes, such as stains or sealants, which is particularly beneficial for achieving a uniform appearance. Therefore, using this method is essential for effective and quality wood finishing.
