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.

How does sanding impact the grain texture of wood?
Sanding removes the old finish and levels the wood surface, which can impact the grain texture. Using coarse grits initially removes material, while fine grits refine the texture, ensuring the wood is smooth and prepped to receive stain and finish without showing sand marks.
