Step 4 · Clean and Sand Stair Surfaces

After repairs, vacuum the stairs thoroughly to remove any dust or debris. Wipe down the surfaces with a tack cloth or a slightly damp rag. Next, use an orbital sander with medium-grit sandpaper (e.g., 80-120 grit) to sand the entire surface of each tread and riser. This will remove any remaining residue and create a uniform, smooth surface. Follow up with fine-grit sandpaper (e.g., 180-220 grit) for a smoother finish. Clean off all sanding dust thoroughly.
