- Use the Right Tools and Grit: Then, choose the appropriate sanding tool, I suggest DEWALT 20V Orbital Sander and start with coarse grit (60-80) to remove imperfections. Switch to finer grits (100-150) for a smoother finish.
- Start at the Top and Work Down: Begin sanding at the top of the staircase, moving down one step at a time to prevent debris from falling onto areas already sanded.
- Sand Treads, Risers, Edges, and Corners: Sand each tread and riser individually, following the wood grain. Use a sanding block or detail sander for edges and corners where power sanders can’t reach.
- Check Smoothness and Clean Between Steps: After sanding, run your hand over the sanded surface to check for smoothness. Remove dust and debris between steps with a vacuum or tack cloth before proceeding to the next step or applying finish.
