How to install hardwood flooring on concrete

Prepare the Concrete Subfloor:

Before installing hardwood flooring on concrete, meticulous preparation is essential. Begin by thoroughly cleaning the concrete surface, ensuring it is free from any dust, dirt, or debris. Use a scraper or grinder to remove any adhesive residues or paint. Additionally, inspect the concrete for cracks or imperfections. If any are present, fill them with a suitable patching compound and allow it to dry completely according to the manufacturer’s instructions. A smooth, clean, and level surface is crucial for a successful hardwood installation.

Install a Moisture Barrier:

Concrete is susceptible to moisture, which can adversely affect hardwood flooring. To mitigate this risk, install a moisture barrier or vapor retarder over the concrete subfloor. Choose a high-quality moisture barrier specifically designed for hardwood flooring installations. This barrier helps prevent moisture from seeping into the hardwood planks, protecting them from potential damage and ensuring long-term durability.

Acclimate the Hardwood Flooring:

Proper acclimatization of hardwood flooring is vital to prevent issues such as warping or buckling after installation. Before laying the flooring, bring the hardwood planks into the room where they will be installed and allow them to acclimate to the room’s temperature and humidity levels for at least 48 hours. This step ensures that the hardwood adjusts to the environmental conditions of its intended location, minimizing the risk of post-installation problems.

Install the Underlayment:

A suitable underlayment helps provide cushioning, sound insulation, and moisture protection for hardwood flooring installed over concrete. Install a foam or cork underlayment over the moisture barrier, following the manufacturer’s guidelines. The underlayment acts as a buffer between the hardwood planks and the concrete subfloor, enhancing comfort underfoot and reducing noise transmission throughout the space.

Install the Hardwood Flooring:

When installing hardwood flooring on concrete, several methods can be employed, including floating, glue-down, or nail-down installations. Each method has its advantages and considerations, depending on factors such as the type of hardwood flooring and the specific requirements of the project. For floating installations, assemble the hardwood planks without fastening them to the subfloor, using tongue-and-groove joints and an appropriate adhesive to secure them together. Glue-down installations involve applying a recommended hardwood flooring adhesive to the concrete subfloor and carefully placing the planks into the adhesive. Nail-down installations require installing a plywood subfloor over the concrete before securing the hardwood planks with nails.

Finishing Touches:

After installing the hardwood flooring, attention to detail is crucial for a polished final appearance. Install baseboards or quarter-round molding around the perimeter of the room to conceal the expansion gap between the flooring and the walls. These finishing touches not only enhance the aesthetic appeal but also help protect the edges of the hardwood planks and create a seamless transition between the flooring and the walls or other surfaces.

Allow for Expansion:

Hardwood flooring naturally expands and contracts in response to fluctuations in temperature and humidity. To accommodate this movement and prevent issues such as buckling or warping, leave a small expansion gap around the perimeter of the room during installation. Typically, a gap of around 1/4 inch is sufficient to allow for expansion while still maintaining a neat and uniform appearance. Be sure to use spacers along the walls to ensure consistent spacing throughout the installation process.

Finish the Hardwood Flooring:

Depending on the type of hardwood flooring installed, applying a finish is often necessary to protect the wood and enhance its visual appeal. Polyurethane is a popular choice for finishing hardwood floors due to its durability and resistance to wear and tear. Before applying the finish, ensure the hardwood surface is clean and free from any dust or debris. Follow the manufacturer’s instructions for the application of the finish, including the number of coats required and the recommended drying times between coats. Once the finish has been applied and allowed to cure, the hardwood flooring will be ready for use.

Maintain Proper Humidity Levels:

Maintaining consistent humidity levels within the room is essential for the long-term stability and performance of hardwood flooring. Fluctuations in humidity can cause the wood to swell or shrink, potentially leading to issues such as gaps between planks or warping. Use a humidifier or dehumidifier as needed to keep humidity levels within the recommended range for hardwood flooring, typically between 30% and 50%. Additionally, avoid excessive exposure to moisture, such as spills or leaks, which can damage the hardwood and compromise its integrity.

Regular Maintenance:

Proper maintenance is key to preserving the beauty and longevity of hardwood flooring installed over concrete. Implement a routine cleaning regimen that includes sweeping or vacuuming the floors regularly to remove dirt, dust, and debris. Use a hardwood floor cleaner recommended by the flooring manufacturer to clean the surface periodically, taking care to avoid excessive moisture. Additionally, promptly address any spills or stains to prevent them from penetrating the wood and causing damage. By following these maintenance practices, you can ensure that your hardwood flooring remains in top condition for years to come.


Conclusion: Installing hardwood flooring on concrete requires patience, precision, and proper technique. By following the steps outlined in this guide and adhering to manufacturer instructions, you can achieve a beautiful and durable floor that enhances the aesthetic appeal of any space.

Remember to allow the floor to settle, perform any necessary touch-ups, and educate yourself on maintenance for long-term enjoyment. With careful planning and attention to detail, you can confidently transform your concrete subfloor into a stunning hardwood masterpiece.
