Refinish a Hardwood Floor: Your Comprehensive Guide

Posted on June 23, 2023


A Complete Guide to Refinish a Hardwood Floor: Step-by-Step Instructions

Hardwood floors are a beautiful and durable option for any home. However, over time, they can get worn out, scratched, and dull. Fortunately, refinishing your hardwood floor can restore its original beauty and extend its lifespan. In this guide, we will walk you through the process of refinishing a hardwood floor step by step.

Understand the Process

Refinishing a hardwood floor involves sanding down the old finish to bare wood and then applying a fresh coat of finish. The process can be labour-intensive and time-consuming, but the results are well worth the effort.

Assess the Condition of Your floor.

Before you start, it’s important to assess the condition of your floor. Minor scratches and dullness can be fixed with a screen and recoat, which involves lightly sanding the floor and applying a new topcoat. However, deep scratches, dents, and discoloration require a complete refinish.

Gather Your Tools and materials.

You’ll need:
  1. Drum sander or orbital sander
  2. Sandpaper (various grits)
  3. Edge sander
  4. Wood filler
  5. Vacuum cleaner
  6. Tack cloth
  7. Stain (optional)
  8. Polyurethane finish
  9. Paintbrushes
  10. Respirator mask
  11. Safety goggles
  12. Ear protection

A Step-by-Step Guide to Refinishing Your Hardwood Floor

Step 1: Prep the Room

Remove all furniture, rugs, and other items from the room. Cover any vents with plastic sheeting to prevent dust from spreading. Wear your safety gear to protect yourself from dust and fumes.

Step 2: Sand the Floor

Rent a drum or orbital sander and start with coarse-grit sandpaper to remove the old finish. Sand the main area of the floor, moving along the grain. Make sure to keep the sander moving to avoid creating divots. Wood Floor Sanding

Step 3: Sand the Edges

Use an edge sander or hand sander to sand the edges of the room where the drum sander couldn’t reach. Be careful not to sand too deeply and create uneven surfaces.

Step 4: Fill Gaps

Inspect the floor for any cracks or gaps, and fill them with wood filler. Let the filler dry as directed.

Step 5: Sand Again

Sand the floor again using medium-grit sandpaper to remove any filler and smooth out the wood. Follow with fine-grit sandpaper for a smooth finish.

Step 6: Clean Up

Vacuum the floor thoroughly and wipe with a damp tack cloth to remove any remaining dust.

Step 7: Apply Stain (Optional)

If you’re changing the colour of your floor, apply your chosen stain. Use a paintbrush to apply the stain along the grain, then wipe off the excess with a cloth. Allow the stain to dry as directed.

Step 8: Apply and Finish

Apply a thin, even coat of polyurethane finish using a high-quality paintbrush. Let it dry, then lightly sand the floor with fine-grit sandpaper. Vacuum, wipe with a tack cloth, and apply a second coat. Repeat for a third coat if desired.

Step 9: Let It Cure

Allow the finish to cure for several days before moving furniture back into the room.


Refinishing your hardwood floor can breathe new life into your space and enhance the beauty of your home. While it can be a DIY project, it requires time, patience, and a bit of elbow grease. However, the satisfaction of restoring your floor to its former glory and the money saved by doing it yourself can make it a worthwhile endeavor. So, put on your DIY hat, gather your tools, and get ready to transform your hardwood floor!
