How to sand your stairs: A simple guide

  1. Prepare the Staircase: At first, you should remove any carpeting or old finish from the stairs. Ensure the area is clear of obstructions and protected with drop cloths.
  2. 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.
  3. 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.
  4. 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.
  5. 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.

Frequently Asked Question

Q: What grit sandpaper for stair treads?

A: The grit number is the rating of the size of abrasive materials on the sandpaper. There are types of grit sandpaper for various steps and for various random orbit sanders. The higher the grit number, the more even finish you will get. Higher grit leaves fewer swirling marks on the wood. You can always start from 80 to 100 grit sandpaper. Then for a softer finish, you can go for 150 Grit. If you are not convinced with 150, you can try 220 grit sandpaper. The lower grit sandpaper is better for scrapping the old finish. We recommend the coarse grit sandpaper for a more enhanced finish. Try a sander that comes with a vacuum dust collection system. This system will help you not to worry about cleaning stuff.
