Can Engineered Timber Flooring Really be Sanded and Refinished?

Engineered timber flooring has become a popular choice among homeowners for its mix of beauty, strength, and flexibility. Many homeowners wonder if they can sand and refinish engineered timber flooring just like traditional hardwood floors. In this post, we will break down what you need to know to keep your flooring looking its best.

Understanding Engineered Timber Flooring

Engineered timber flooring is made up of several layers. The top layer is usually real hardwood, while the layers underneath are made from materials like plywood. This multi-layer construction provides the flooring with excellent stability against changes in temperature and humidity, making it suitable for various environments, including basements and kitchens.

The thickness of the hardwood veneer is key. It can range from 0.6mm to 6mm or more. For instance, a product with a 3mm veneer allows for several refinishing options, while a flooring with a 0.6mm veneer may not be suitable for sanding at all.

Can Engineered Timber Flooring Be Sanded?

The short answer is yes, but with conditions. Most engineered timber flooring can be sanded, but the ability to do so relies on the thickness of the hardwood veneer. Typically, if the veneer is at least 2-4mm thick, you can safely sand it to eliminate scratches and blemishes.

If the veneer is too thin, sanding risks exposing the core layers, leading to irreversible damage. For a better understanding, consider this: A floor with a 4mm veneer allows for sanding multiple times, whereas a floor with a 0.6mm veneer cannot be sanded back.

The Refinishing Process

Once you confirm that your flooring is suitable for sanding, you can move forward with the refinishing process, which generally includes the following steps:

1. Preparation: Start by removing all furniture and rugs. This makes the space clear for efficient work.

   
   

2. Cleaning: Thoroughly clean the surface to eliminate dust and debris.

   
   

3. Sanding: Using a drum sander or floor buffer equipped with appropriate sandpaper, begin sanding. Start with coarse grit and progress to finer grits. This could mean starting with 30-grit and ending with 120-grit for a smooth finish.

   
   

4. Dust Removal: After sanding, ensure all dust is removed to help the finish adhere well.

   
   

5. Applying Finish: Apply a suitable finish for engineered timber, such as polyurethane or water-based finishes. Always adhere to the manufacturer’s application guidelines for the best results.

   
   

6. Curing: Allow the finish to cure as per the recommended time—usually around 24 to 48 hours—before moving furniture back in.

   
   

Benefits of Sanded and Refinished Engineered Timber Flooring

Sanding and refinishing your engineered timber flooring can provide several advantages:

• Visual Upgrade: Removing scratches and blemishes provides a fresh, appealing look to your floors. Up to 80% of visible imperfections can be eliminated with proper refinishing. You can also change the finished colour of the floor, if you opted originally for a light oak, you can seal it with a dark brown.

  
  

• Extended Lifespan: Regular maintenance can prolong the life of your flooring by up to 20 years when done correctly.

  
  

• Enhanced Property Value: Well-maintained floors can boost your property’s marketability, potentially increasing value by up to 10%

  
  
  
  

Possible Drawbacks

While there are many benefits, it is essential to consider potential downsides:

• Cost: Professional services for sanding and refinishing can range from $25 to $50 per square metre. DIY efforts can save money but may require significant time, as well as tools and materials.

  
  

• Damage Risk: Incorrect sanding could lead to severe damage, especially with thinner veneers.

  
  

• Limited Refinishing: Unlike traditional hardwood, engineered flooring can only be sanded a limited number of times—often just once or twice depending on the product veneer thickness.

  
  

Maintenance Tips for Longevity

To extend the life of your engineered timber flooring and reduce the need for extensive refinishing, consider these maintenance tips:

• Regular Cleaning: Sweep or vacuum at least once a week to keep debris from scratching surfaces.

  
  

• Use Area Rugs: Place rugs in high-traffic zones to lessen wear and tear.

  
  

• Humidity Control: Use a dehumidifier or humidifier to maintain consistent humidity levels. Aim for a humidity range of 30%-50% to prevent warping.

  
  

• Avoid Harsh Chemicals: Stick to pH-balanced wood cleaners to protect the finish from deterioration.

  
  

When to Seek Professional Help

If you are unsure about the type of engineered timber flooring you have or its suitability for sanding, consulting with a professional can be beneficial. A professional can evaluate your flooring’s condition and veneer thickness, giving tailored recommendations.

If you lack experience in DIY projects, hiring a professional can save you time and ensure high-quality results.

Final Thoughts

Engineered timber flooring can be sanded and refinished, but evaluating the thickness of the hardwood veneer is crucial in making this decision. Regular maintenance, like cleaning and using area rugs, can help minimize damage and extend the time between refinishing jobs.

While the advantages typically outweigh the challenges, consulting a professional can provide peace of mind that your flooring will remain beautiful and durable for years to come.
