Before diving into the refinishing process, it's important to understand what engineered wood floors are. Unlike solid hardwood floors, which are made from a single piece of wood, engineered wood floors consist of multiple layers. The top layer is a thin veneer of real wood, which gives it the appearance of solid wood. Beneath this veneer are layers of plywood or high-density fiberboard.
Composition and Structure
Engineered wood floors typically have three to five layers. The core layers are constructed from high-quality plywood or fiberboard, providing stability and strength. The top veneer layer, which is made from real hardwood, varies in thickness and determines the floor's refinishing potential.
Benefits of Engineered Wood
The construction of engineered wood floors offers several benefits. They are more resistant to moisture and temperature fluctuations compared to solid wood, making them ideal for basements and kitchens. Additionally, their layered design reduces the likelihood of warping or cupping over time.
Limitations to Keep in Mind
While engineered wood floors offer stability, the thin veneer layer limits the number of times they can be refinished. Each refinishing process removes a small amount of the veneer, so it's essential to assess the condition and thickness of the top layer before proceeding.
Can You Refinish Engineered Wood Floors?

The short answer is yes, you can refinish engineered wood floors. However, the feasibility largely depends on the thickness of the top veneer layer. Generally, if the veneer is at least 2mm thick, you can sand and refinish the floor at least once. Floors with a thicker veneer, such as 3mm or more, can typically be refinished multiple times.
Assessing the Veneer Thickness
To determine if your engineered wood floor can be refinished, you'll need to assess the thickness of the veneer. This can often be done by removing a floor vent or a threshold to see the layers of your flooring. If you're unsure, consult with a professional who can give you an accurate assessment.
Consulting with Professionals
If you're uncertain about the thickness or condition of your veneer, it's wise to consult a flooring professional. They can provide an expert evaluation and suggest whether refinishing is a viable option. A professional assessment can prevent potential damage and ensure the longevity of your floors.
Making the Decision
Once you have assessed the veneer thickness, consider whether refinishing is necessary. Sometimes, a simple re-coating or minor repairs might suffice. Evaluate the overall condition of the floor and weigh the benefits of refinishing against the potential risks and costs.
The Refinishing Process

Refinishing engineered wood floors involves sanding down the top layer to remove scratches, dents, and old finish, then applying a new finish to protect and beautify the surface.
Preparation
Before you begin, it's crucial to prepare your space. Remove all furniture and clean the floor thoroughly to remove dust and debris. Ensure the area is well-ventilated, as the refinishing process can produce strong fumes.
Cleaning and Organizing the Space
Start by removing furniture, rugs, and any items from the room. Vacuum or sweep the floor to eliminate dust and dirt. A clean and organized space will facilitate a smoother refinishing process.
Ventilation and Safety
Proper ventilation is essential during refinishing. Open windows and doors to allow fresh air to circulate. Wear protective gear such as masks and goggles to safeguard against dust and fumes.
Gathering Tools and Supplies
Prepare the necessary tools and materials, including sanders, sandpaper, stains, and finishes. Having everything ready will streamline the process and reduce interruptions.
Sanding
Sanding is a delicate process when it comes to engineered wood floors. You'll need to remove the old finish without sanding through the veneer. It's often best to use a professional-grade sander with a fine-grit sandpaper to carefully sand the surface. Hiring a professional is recommended if you lack experience, as improper sanding can permanently damage the floor.
Choosing the Right Sander
Select a sander suitable for engineered wood floors, such as an orbital sander. These sanders offer precision and control, reducing the risk of excessive veneer removal.
Techniques for Effective Sanding
Begin sanding with a fine-grit sandpaper, gradually moving to finer grits for a smooth finish. Sand in the direction of the wood grain to avoid scratches. Take care to evenly sand the entire surface for a uniform appearance.
Professional Assistance
If you're inexperienced or unsure about sanding, consider hiring a professional. They have the expertise and equipment to achieve optimal results without compromising the veneer.
Staining and Finishing
Once the old finish is removed, you can apply a new stain to achieve your desired color. After staining, apply a protective finish, such as polyurethane, to seal the surface. This not only enhances the appearance but also adds a layer of protection against wear and tear.
Selecting the Right Stain
Choose a stain that complements your home decor and highlights the wood's natural beauty. Test the stain on a small area to ensure it achieves the desired color.
Applying the Finish
Apply the finish evenly using a brush or applicator. Allow sufficient drying time between coats to prevent smudging or uneven application. The finish will protect the wood and enhance its visual appeal.
Final Touches
Inspect the floor for any touch-ups or imperfections. Lightly buff the surface if needed to achieve a polished look. Once satisfied, allow the floor to cure completely before moving furniture back in.
Benefits of Refinishing Engineered Wood Floors

Refinishing engineered wood floors can offer several benefits:
