Let’s explore this topic in more depth.
Understanding Engineered Wood Flooring
Engineered wood flooring is composed of multiple layers of wood veneer, with the top layer being the desired hardwood species. Underneath the veneer, there are layers of plywood or high-density fiberboard (HDF), which provide stability and prevent warping or cupping. The layers are bonded together under heat and pressure to create a strong and dimensionally stable product.
One of the key advantages of engineered wood flooring is its ability to be installed over a variety of existing flooring types, including concrete and plywood. However, the question arises whether it can also be installed over hardwood flooring. Let’s examine the considerations and potential challenges.
Considerations for Installing Engineered Wood Flooring over Hardwood
- Height Differences: One of the primary concerns when installing engineered wood flooring over hardwood is the potential increase in height. Since engineered wood is already a thicker flooring option compared to traditional hardwood, adding another layer on top might result in a noticeable height difference. This height discrepancy could create issues with door clearances and transitions to adjacent rooms.
- Stability and Performance: Another consideration is the stability and performance of the engineered wood flooring when installed on top of a hardwood floor. While hardwood is a stable surface, it might have imperfections or unevenness that can affect the performance and longevity of the engineered wood flooring. It is crucial to evaluate the condition and levelness of the existing hardwood before proceeding with the installation.
- Moisture and Moisture Vapor Transmission (MVT): Moisture can greatly impact the durability and longevity of any wood flooring product. Hardwood, being a natural material, is susceptible to moisture damage. If there are any moisture issues, such as leaks or high humidity levels, it is critical to address them before installing engineered wood flooring. Additionally, one should consider the moisture vapor transmission (MVT) through the hardwood and its potential impact on the engineered wood’s stability.
Installation Considerations and Best Practices
If you have carefully evaluated the above considerations and still wish to install engineered wood flooring over hardwood, here are some installation best practices to follow:
- Surface Preparation: Thoroughly clean and inspect the existing hardwood surface. Address any repairs, such as loose boards, squeaks, or damaged areas. Level the floor, ensuring it is relatively flat and free of significant irregularities.
- Moisture Testing: Conduct a moisture test on the hardwood floor to evaluate its moisture content. This step is essential to prevent future moisture-related issues. Follow the manufacturer’s guidelines for the acceptable moisture levels.
- Adhesive: Use an appropriate adhesive recommended by the flooring manufacturer. Follow the adhesive manufacturer’s instructions carefully, ensuring proper coverage and application techniques.
- Acclimation: Prior to installation, allow the engineered wood flooring to acclimate to the room’s temperature and humidity. Follow the manufacturer’s recommendations for the acclimation period.
- Installation Methods: Depending on the specific engineered wood flooring product and manufacturer, there are different installation methods available, including floating, nail-down, or glue-down. Choose the method that suits your needs and aligns with the manufacturer’s guidelines.
Conclusion: Proceed with Caution
While it is possible to install engineered wood flooring over hardwood, it is crucial to proceed with caution. Take into account the height differences, stability, and moisture-related considerations. Evaluate the condition of the existing hardwood floor and follow the recommended installation best practices to ensure a successful and long-lasting installation. Consulting with a professional flooring installer or contacting the engineered wood flooring manufacturer for guidance can provide valuable insight into the specific compatibility of their product with hardwood surfaces.
