Engineered wood flooring has gained popularity in recent years as it offers the beauty and elegance of hardwood floors while being more resistant to moisture and humidity. However, many homeowners wonder if it is possible to install engineered wood floors on a concrete slab. The answer is yes, it is indeed possible to install these floors on concrete, provided a few crucial steps are followed. In this article, we will discuss the necessary preparations and techniques to successfully install engineered wood floors on concrete.
Preparation is Key
Proper preparation is crucial when it comes to installing engineered wood floors on concrete. Here are some important steps to take before starting the installation:
- Check the Concrete Moisture Levels: Moisture can be a big issue when installing any type of wood flooring on concrete. It is essential to check the moisture levels of the concrete slab using a moisture meter. If the moisture levels exceed the manufacturer’s recommendations, it may be necessary to take additional steps to mitigate moisture before proceeding with the installation.
- Evaluate the Subfloor Condition: Before proceeding with the installation, check the condition of the concrete subfloor. Ensure that it is clean, level, and free of any cracks or imperfections. Any noticeable issues with the subfloor should be addressed before installation to avoid future problems.
- Acclimate the Engineered Wood Flooring: Acclimating the engineered wood flooring is necessary to allow it to adjust to the indoor environment. Store the flooring in the installation area for a minimum of 48 to 72 hours before installation, ensuring that the temperature and humidity levels are similar to the intended use environment.
Moisture Barrier Installation
To protect the engineered wood flooring from moisture rising from the concrete slab, it is essential to install a moisture barrier. Here’s what you need to know about moisture barrier installation:
- Choose the Right Moisture Barrier: Select a suitable moisture barrier based on the moisture levels found during the initial testing. There are various types of moisture barriers available in the market, ranging from moisture-resistant adhesive to plastic sheeting. Consult with a flooring professional to determine the best option for your specific situation.
- Install the Moisture Barrier: Follow the manufacturer’s instructions to install the moisture barrier effectively. It usually involves rolling out the barrier over the concrete slab and taping the seams tightly to create a continuous barrier. Ensure that the barrier extends up the walls by 2 to 4 inches to provide additional protection from moisture.
Engineered Wood Floor Installation
Once the moisture barrier is installed and the preparation steps are completed, you can proceed with the actual installation of the engineered wood flooring. Here’s how to do it:
- Choose the Right Installation Method: Engineered wood flooring can be installed using various methods, such as glue-down, floating, or nail-down. However, when installing on concrete, the floating method is the most commonly used. This method involves laying the flooring over the moisture barrier without adhering it directly to the concrete.
- Lay the Flooring: Start by laying the first row of engineered wood flooring against one wall, leaving an expansion gap of around ¼ inch between the flooring and the wall. Continue laying subsequent rows, ensuring the tongue-and-groove joints fit together securely. Use a tapping block and a mallet to tap the boards into place. Cut the last pieces of flooring to fit using a saw.
- Finish the Installation: Once the flooring is installed, remove any excess adhesive or debris and allow the floor to settle for at least 24 hours. Finally, install the baseboards or quarter-round molding around the perimeter to cover the expansion gap and provide a finished look.
Installing engineered wood floors on concrete is possible with the right preparations and techniques. Properly acclimate the flooring, install a moisture barrier, and follow the recommended installation methods to ensure a successful and long-lasting installation. By taking the necessary steps, you can enjoy the beauty of engineered wood flooring in any room with a concrete subfloor.
