Sanding acts to flatten and smooth the wood surface by removing old finish, imperfections, and surface fibers. The texture of the grain is influenced by the grit sequence used; starting with coarser abrasives levels uneven boards, while sequential fine-grit sanding minimizes scratching and enhances the natural appearance of the grain. If the wood is over-sanded or sanded with improper technique, it can cause 'chatter' marks or gouges that disrupt the grain pattern and become highly visible once stain is applied.
