Whether you’re a DIY enthusiast or planning to hire professionals, knowing the ins and outs of this approach is essential for achieving a beautiful and lasting result.

Considerations Before Installing Laminate Over Existing Laminate

Before deciding to lay laminate flooring over an existing laminate floor, several important factors must be evaluated to ensure a successful installation. The condition of the current flooring plays a critical role; the surface must be flat, stable, and free of damage such as warping, loose boards, or water damage. Any imperfections can cause issues with the new layer, including unevenness, squeaking, or premature wear.

Another consideration is the height increase resulting from adding an additional layer of laminate. This can affect door clearances, transitions to other flooring types, and baseboards. It’s essential to measure these areas carefully to avoid problems after installation.

Moisture levels should also be assessed. While laminate floors are generally moisture-resistant, excessive moisture trapped between layers can lead to mold or damage. Proper moisture barriers or underlayment may be required to mitigate this risk.

Lastly, the type of underlayment under the existing laminate must be identified. If the current floor has an attached underlayment, installing a new underlayment may not be necessary, but if absent, it should be added to improve comfort, sound absorption, and durability.

Steps to Properly Install Laminate Over Existing Laminate

The installation process of laminate flooring over an existing laminate floor requires careful preparation and execution:

  • Inspect and Clean the Existing Floor: Remove any debris, dirt, or wax buildup. Repair any damaged boards to create a smooth, stable surface.
  • Check for Levelness: Use a level to identify any uneven areas. Sand down high spots or fill low spots with leveling compound.
  • Remove Baseboards and Thresholds: This allows for the new flooring to expand and contract freely without obstruction.
  • Install Underlayment (if needed): Depending on the current floor’s underlayment, add a compatible underlayment to provide cushioning and moisture protection.
  • Acclimate New Laminate: Let the new laminate planks acclimate to the room temperature and humidity for at least 48 hours.
  • Lay the New Flooring: Begin installation following the manufacturer’s instructions, ensuring proper expansion gaps around the perimeter.
  • Reinstall Baseboards and Transitions: After the flooring is installed, reinstall or replace baseboards and transition strips to complete the look.
