Section 1: Understanding Engineered Wood Floors

1.1 Composition and Structure

Before we dive into the sanding and refinishing process, it’s essential to understand what engineered wood floors are made of. Unlike solid hardwood, these floors are composed of multiple layers of different kinds of wood, with a veneer of hardwood on top. This composition grants them stability and resistance to environmental changes.

1.2: Why Refinish Engineered Wood Floors?

Refinishing engineered wood floors can help remove scratches, dents, and signs of ageing, giving them a new lease on life. Additionally, it can be a cost-effective way to enhance the aesthetic value of your home, increasing its market value in the process.

Section 2: Preparation for Sanding and Refinishing

2.1 Materials and Tools Required

Gathering the right tools and materials is the first step in your sanding and refinishing project. Here is a list of items you would typically need:

  • Sanding machine (orbital or drum sander)
  • Sandpaper (varying grits)
  • Wood filler
  • Vacuum cleaner
  • Protective gear (mask, goggles, ear protection)
  • Staining materials (if desired)
  • Polyurethane finish

2.2 Preparing the Space

Before you start, ensure to remove all furniture, rugs, and other items from the room. Cover any air vents to prevent dust from spreading, and seal off the area to contain the dust generated during sanding.

3.1 Choosing the Right Grit

When sanding engineered wood floors, starting with the right grit is crucial. Begin with a coarser grit to remove the existing finish and surface imperfections, gradually moving to finer grits for a smooth finish.

3.2 Sanding Process

The sanding process involves several passes over the floor, with careful attention paid to high-traffic areas or spots with significant damage. Remember that engineered wood floors have a limited amount of hardwood veneer on top, so sand conservatively to avoid sanding through this layer.

3.2.1 Initial Inspection

Before you begin, inspect the floor thoroughly to identify areas that might need extra attention. Look for deep scratches, dents, or uneven spots. Knowing these areas in advance will help you plan the sanding process more effectively.

3.2.2 Equipment Handling

Operating sanding equipment requires a certain level of skill. It is advisable to keep the sander moving to prevent dips and gouges caused by leaving the machine in one spot for too long. A gentle, sweeping motion ensures an even removal of the old finish.

3.2.3 Step-by-Step Sanding

Start with coarse-grit sandpaper to remove the old finish and surface imperfections. Usually, you would begin with 40- or 60-grit sandpaper. After the initial pass, vacuum the floor to remove dust and debris.

Next, switch to medium-grit sandpaper, such as 80 or 100 grit, for the second pass. This will help to smooth out any rough patches and prepare the floor for the final sanding stage.

The final stage involves using a finer grit, like 120 or 150 grit sandpaper, to achieve a perfectly smooth surface. At this point, the floor should be free of old coatings and ready for refinishing.

3.2.4 Corners and Edges

Don’t overlook the corners and edges, which might not be accessible with the main sanding machine. Use an edge sander or a hand-held sander to reach these spots, ensuring a uniformly sanded surface across the entire floor.

3.2.5 Final Cleanup

After the sanding is completed, conduct a thorough cleanup to remove all traces of dust. This not only includes vacuuming the floor but also wiping down walls and any furniture in the vicinity. A tack cloth can be used to pick up the finest dust particles left on the floor.

3.2.6 Inspection and Touch-Ups

Lastly, inspect the floor carefully for any missed spots or inconsistencies. If necessary, perform touch-ups using a hand sander or a similar tool to refine areas that need a bit more work. The goal is to achieve a uniform, smooth surface that is ready to absorb the new finish evenly.

4.1 Filling the Gaps

After sanding, any gaps or cracks should be filled with a suitable wood filler. Allow the filler to dry as per the manufacturer’s instructions, then sand it down to create a uniform surface.

4.2 Staining the Floor

If you choose to stain your floor, now is the time. Select a stain that complements your home’s décor and apply it evenly, following the grain of the wood. Wait for the stain to dry completely before moving on to the next step.

4.3 Applying the Finish

The final step in the process is applying a protective finish to the floor. Polyurethane finishes are popular choices due to their durability and ease of application. Apply the finish evenly across the floor, allowing sufficient drying time between coats.

Section 5: Maintaining Your Newly Refinished Floors

5.1 Cleaning and Maintenance

To keep your newly refinished floors looking their best, regular cleaning with a suitable cleaner is essential. Avoid using abrasive cleaning agents, as they can damage the finish over time.

5.2 Preventing Scratches and Dents

Prevent scratches and dents by using furniture pads under heavy items and avoiding walking on the floor with sharp-heeled shoes. Placing rugs in high-traffic areas can also help protect the floor from wear and tear.


Sanding and refinishing your engineered wood floors can rejuvenate your space, giving it a fresh, new look. By understanding the unique characteristics of engineered wood floors and following the steps outlined in this guide, you can achieve professional-level results with your refinishing project.

With proper preparation, the right tools, and careful execution, you can breathe new life into your floors, adding value and beauty to your home. Remember, maintaining your floors post-refinishing is vital to ensuring their longevity and enduring appeal.

In a nutshell, sanding and refinishing engineered wood floors can be a rewarding project that restores the splendour and grace of your floors, making them a focal point in your home once again. Happy refinishing!
