Laminate Flooring Over Floorboards

Installing laminate flooring over floorboards requires careful preparation and the right tools. Ensure the floorboards are in good condition, clean, and level. Use an underlayment for moisture protection and a smooth surface. Leave expansion gaps, acclimate the laminate, and choose the appropriate installation method.

Things To Consider

Before laying laminate flooring over floorboards, there are several important considerations to ensure a successful installation:

  • Inspect the floorboards for any signs of damage, such as warping, rot, or unevenness. Ensure that the floorboards are stable and in good condition to support the laminate flooring.
  • Check the moisture levels of the floorboards to prevent issues like mold, mildew, or warping. Laminate flooring is sensitive to moisture, so it’s crucial to ensure that the floorboards are dry and properly sealed.
  • Prepare the floorboards by thoroughly cleaning and leveling them. Remove any debris, dust, or existing flooring material. Use a leveling compound if necessary to create a flat surface.
  • Install an appropriate underlayment over the floorboards before laying the laminate flooring. The underlayment helps to reduce noise, provides insulation, and creates a smoother surface for the laminate to be installed on.
  • Leave expansion gaps around the perimeter of the room and at doorways to allow for natural expansion and contraction of the laminate flooring. These gaps are typically around 1/4 inch to 1/2 inch wide and should be covered with baseboards or trim.
  • Allow the laminate flooring to acclimate to the room’s temperature and humidity for at least 48 hours before installation. This helps to prevent issues like buckling or gaps once the flooring is installed.
  • Choose the appropriate installation method for the laminate flooring, such as floating, glue-down, or nail-down, based on the manufacturer’s recommendations and the condition of the floorboards.Invest in high-quality laminate flooring that is suitable for installation over floorboards. Consider factors such as thickness, durability, and warranty when selecting the laminate flooring.
  • Consider the usage of the room where the laminate flooring will be installed. High-traffic areas may require a more durable laminate with a thicker wear layer to withstand wear and tear.
  • If you’re unsure about any aspect of the installation process or if the floorboards require extensive repair, consider hiring a professional installer to ensure a proper and long-lasting installation.

Preparing the Floorboards

Before diving into the installation process, carefully inspect the existing floorboards. Look for any signs of damage, warping, or unevenness. Addressing these issues beforehand will contribute to a smoother installation process and a better end result.

To achieve a flawless finish, it’s crucial to address any uneven surfaces. Use a leveling compound or plywood to even out the floorboards, creating a stable foundation for the laminate flooring.

Clean the floorboards thoroughly, removing any debris, dust, or old adhesives. Repair any damaged or loose floorboards to ensure a solid and secure base for the laminate flooring.


To lay laminate flooring over floorboards, you’ll need a variety of tools to ensure a smooth and efficient installation. Here’s a list of essential tools:

  • Tape Measure: For accurate measurements of the room and the laminate flooring planks.
  • Pencil: To mark cut lines on the laminate flooring planks and underlayment.
  • Safety Gear: Including gloves and safety glasses to protect yourself during the installation process.
  • Circular Saw or Jigsaw: For cutting laminate flooring planks to size, especially for fitting them around corners, doorways, or other obstacles.
  • Underlayment: A moisture barrier underlayment specifically designed for laminate flooring.
  • Utility Knife: For cutting the underlayment and making precise cuts during installation.
  • Hammer and Pry Bar: To remove baseboards or trim if necessary and to tap the laminate flooring planks into place during installation.
  • Spacers: To maintain the required expansion gap between the laminate flooring and walls or other obstacles.
  • Pull Bar: To help snugly fit the last row of laminate flooring planks against the wall.
  • Tapping Block: To protect the edges of the laminate flooring planks while tapping them into place with a hammer.
  • Level: To ensure the floorboards are level before installing the laminate flooring.
  • Moisture Meter: To check the moisture levels of the floorboards and ensure they are suitable for laminate flooring installation.
  • Vacuum Cleaner: For cleaning the floorboards and subfloor before installing the underlayment and laminate flooring.
  • Installation Kit: Some laminate flooring manufacturers offer specialized installation kits that include tapping blocks, pull bars, and spacers designed specifically for their products.
  • Knee Pads: For comfort and knee protection during the installation process, especially if you’re working on a large area.

Installation Process

  1. Before installation, it’s crucial to allow the laminate flooring to acclimate to the room’s conditions. Unbox the laminate planks and let them sit in the room for the manufacturer-recommended time. This helps the material adjust to the temperature and humidity levels of the space, reducing the risk of expansion or contraction after installation.
  2. Careful planning of the layout is essential for a visually appealing and well-balanced result. Start by determining the direction of the planks based on the room’s dimensions and the source of natural light. Generally, laying the planks parallel to the longest wall creates an attractive look. Additionally, stagger the seams between rows to avoid a repetitive pattern and enhance the overall aesthetic.
  3. Use a saw or a laminate cutter to trim the planks to fit the edges of the room accurately. Take precise measurements and make straight cuts to achieve clean and professional-looking edges. When encountering obstacles like door frames or heating vents, carefully cut the laminate planks to fit around them seamlessly.
  4. Place spacers along the perimeter of the room, maintaining the recommended expansion gap between the laminate flooring and the walls. The expansion gap allows the material to naturally expand and contract with changes in temperature and humidity, preventing issues like buckling or warping over time.
  5. Depending on the type of laminate flooring chosen, follow the manufacturer’s guidelines for securing the planks. If using a click-lock system, ensure that each plank clicks securely into place. For adhesive installations, apply the recommended adhesive according to the instructions. Use a tapping block and pull bar to assist in connecting the planks tightly, ensuring a stable and uniform surface.
  6. Install transition strips or molding where the laminate flooring meets different types of flooring or transitions between rooms. This not only adds a finishing touch to the installation but also provides a smooth transition and protects the edges of the laminate planks. Carefully secure transition pieces in place, ensuring they complement the overall design.
  7. Periodically check the installation for uniformity as you progress. Ensure that the seams between planks are tight and consistent, creating a seamless appearance. Use a tapping block and pull bar as needed to eliminate any gaps or irregularities in the flooring surface.
  8. Throughout the installation process, clean any adhesive or debris that may accumulate on the laminate surface. Regularly inspect the installed planks for visible defects or issues, addressing them promptly to maintain the quality of the flooring.
  9. After completing the installation, conduct a final inspection of the entire floor. Check for any loose or uneven planks, and make any necessary adjustments. Walk across the floor to ensure it feels stable and secure.
  10. If adhesive was used during installation, allow sufficient time for it to cure before placing furniture or heavy loads on the floor. Follow the manufacturer’s recommendations for the specific adhesive used.
  11. Once the laminate flooring is securely in place, install baseboards and trim to cover the expansion gap and provide a polished finish. Securely attach these finishing elements to the walls rather than the flooring to allow for the natural expansion and contraction of the laminate.
