How should the grain of wood be oriented when sanding?

Sanding with the grain is essential for achieving a smooth finish and avoiding damage to the wood surface. When the sandpaper is moved along the direction of the wood fibers, it minimizes the risk of scratching or creating uneven surfaces. This method allows for better removal of imperfections while respecting the natural appearance of the wood.

Sanding against the grain may lead to scratches and a rough texture, which can compromise the quality of the final finish. Similarly, sanding across the grain can create visible patterns and damage that makes further refinishing difficult. Circles may seem effective for smoothing, but they can also lead to inconsistencies and are not the best method for wood surfaces. Thus, sanding with the grain is the preferred technique to ensure optimal results in park maintenance tasks.
