Materials Needed
| Material | Use |
|---|---|
| Sandpaper (60-220 grit) | Progressive sanding |
| Wood filler | Repair holes and damage |
| Water/oil-based polyurethane | Protective finish |
| Wood stain (optional) | Color enhancement |
| White trim paint | Risers and stringers |
| Masking tape | Surface protection |
| Caulk | Gap filling |
| Shoe molding/trim | Cover gaps |

Step 1: Prepare and Clean
Remove all nails, tack strips, and screws from stairs. Sweep or vacuum all debris completely. Clear the area of furniture and dust.
Set up proper ventilation with fans. Gather all tools, including sanders, brushes, and safety equipment, before starting work.
Step 2: Sand the Surfaces
Start with 60-grit sandpaper for damaged wood or 120-grit sandpaper for good-condition stairs. Sand treads, risers, and stringers systematically.
Use an orbital sander for the main areas, a palm sander for the corners, and a sanding sponge for the detailed spots. Always sand with the grain direction.
Step 3: Progress Through Grits
Move through progressively finer sandpaper grits: 80, 120, then 150-grit. Vacuum thoroughly between each grit change.
This removes scratches from previous sanding and creates a smooth surface. Check for missed spots and ensure even coverage across all surfaces.
Step 4: Fill and Repair
Apply wood filler to holes, gouges, and damaged areas using a spackle knife. Let dry completely according to the manufacturer’s instructions.
Sand-filled areas are smoothed with 150-grit paper. Vacuum all dust and wipe clean with a microfiber cloth before proceeding.
Step 5: Apply Stain (Optional)
Mask edges with tape to protect areas you’ll paint. Apply pre-stain wood conditioner if needed. Apply stain evenly with a brush or a cloth, following the wood grain.
Wipe excess immediately. Allow 24-48 hours to dry completely before applying the finish.
Step 6: Apply Finish Coats
Use water-based or oil-based polyurethane finish. Apply thin, even coats with a quality brush. Work systematically to avoid brush marks.
Allow proper drying time between coats. Apply 2-3 coats for durability. Maintain airflow with fans during the drying process.
Step 7: Paint Trim and Final Details
Mask stair treads with tape. Apply caulk to gaps where the trim meets the stairs. Paint risers and stringers with quality trim paint.
Remove the tape while the paint is slightly wet. Install shoe molding or trim pieces to cover gaps. Clean up and inspect final results.
Step 8: Test Stain Drying
After applying the stain, test drying by wiping with a cloth every few hours. Red oak takes longer to dry and may continue bleeding stain.
Wait 24-48 hours minimum. Apply fans for better airflow. Don’t rush this step, or finish won’t adhere properly.
Step 9: First Finish Coat Application
Apply a thin, even coat of polyurethane using the quality brush. Work systematically from one end to the other. Don’t overload the brush or create puddles.
Make finishing passes to remove brush marks. Maintain consistent airflow with fans during the entire drying process.

Maintenance Tips for Long-Lasting Stair Finish
- Regular Cleaning: Sweep stairs daily and mop weekly with wood-safe cleaner to prevent dirt buildup and surface scratches.
- Use Protective Mats: Place runners or mats on high-traffic areas to reduce wear and protect the finish from daily use.
- Control Moisture: Keep humidity levels between 30-50% and clean spills immediately to prevent water damage and warping issues.
- Avoid High Heels: Discourage wearing stilettos or cleats on stairs as they create dents and gouges in the wood surface.
- Annual Inspection: Check for loose boards, worn finish, or damage each year and address issues before they become major problems.
- Recoat When Needed: Apply a fresh polyurethane coat every 3-5 years, depending on traffic, to maintain protection and appearance levels.
