Can a fan help fresh wall paint dry?

Gentle air circulation can help in suitable room conditions. Keep the space clean and aim airflow indirectly so dust is not blown onto the wet finish. If outdoor air is more humid, opening windows may not improve drying. Follow the coating's ventilation and environmental guidance, especially when working with solvent-containing products.

Does a higher sandpaper number mean it removes material faster?

Usually the opposite: higher grit numbers indicate finer abrasive particles, while lower numbers are coarser. Coarse paper removes material quickly but can leave deep scratches. Select a starting grit for the material and task, then progress finer as needed. Identify unknown old coatings before sanding, especially where lead paint may be present.

Why did sanding leave scratches that show through the finish?

The abrasive may have been too coarse, or earlier scratches were not removed before moving to finer paper. Test the grit sequence on comparable material and use controlled pressure. A finish often highlights scratches rather than hiding them. Do not keep aggressively sanding thin veneer or laminate in an attempt to erase deep damage.
