What is the primary function of sanding wood?

The primary function of sanding wood is to smooth the wood surface and prepare it for finishing. This process involves the use of sandpaper or sanding tools to remove rough spots, splinters, and irregularities, resulting in a smoother surface that enhances the appearance and feel of the wood. Smoothing the surface is crucial because it allows for better adhesion of paints, stains, or finishes, which ultimately leads to a more professional and durable final product. Properly sanded wood can help achieve a finer finish and prevent imperfections from showing up once the finishing materials are applied.
