Applying the Finish

Once the sanding is complete, you can apply the new finish. This process can significantly enhance the appearance and durability of your floors.

  • Staining (Optional): If you wish to change the color of the wood, apply a wood stain before the finish. Follow the manufacturer’s instructions for drying times.
  • Applying the Finish: Use a paint applicator or roller for large areas, and an edger for corners. Apply thin, even coats and follow the manufacturer’s recommendations for drying times between coats.
Finish Type Drying Time Coats Recommended
Water-Based 2-4 hours 2-3 coats
Oil-Based 6-8 hours 3-4 coats

Final Touches and Maintenance

After the final coat of finish has dried, it’s essential to take care of the newly refinished floors properly.

  • Reinstall Baseboards and Furniture: Once the finish is completely cured, reinstall any baseboards and move furniture back into place carefully to avoid scratching the surface.
  • Regular Maintenance: To keep your floors looking their best, regularly sweep or vacuum to remove dirt and debris. Use a damp mop with a cleaner appropriate for engineered hardwood. Avoid excessive water as it can damage the finish.

By following these steps, you can achieve beautifully refinished engineered hardwood floors that will enhance the aesthetic appeal of your space.

Preparing the Area

Clearing the space is crucial to ensure a smooth refinishing process. Follow these steps:

  • Remove Furniture: Take out all furniture, rugs, and any other items from the area.
  • Clean the Floors: Sweep and vacuum the engineered hardwood to eliminate dust and debris. Use a damp mop for any remaining dirt, but ensure the floor is completely dry before proceeding.
  • Inspect the Surface: Look for any damage or wear. Minor scratches can be repaired, but significant issues may require professional assessment.

Gathering Tools and Materials

Before starting, gather all necessary tools and materials:

Tools/Materials Purpose
Floor sander To sand the surface evenly
Edger For corners and edges
Sandpaper (various grits) To progressively smooth the floor
Vacuum To clean dust between sanding stages
Wood filler To repair deep scratches and gouges
Finish (polyurethane or oil-based) To protect and enhance the floor’s appearance

Sanding the Floors

Sanding is a critical step in refinishing engineered hardwood floors. Follow this process:

  1. Choose the Right Grit: Start with a coarse grit (e.g., 36-60) to remove the old finish and imperfections.
