Considerations Before Laying Laminate Over Existing Laminate

When deciding to install laminate flooring directly over an existing laminate surface, several important factors must be evaluated to ensure the longevity and performance of the new floor. One of the primary considerations is the condition of the existing laminate. The old laminate must be structurally sound, without any loose, warped, or damaged planks. Any imperfections in the base layer can transfer through to the new laminate, causing unevenness or even damage over time.

Another key aspect is the height increase that results from layering laminate floors. Adding a second layer will raise the floor level, which may affect door clearances, transitions to other rooms, and the height of baseboards or cabinetry. It is essential to measure these clearances beforehand to avoid costly modifications later.

Moisture levels are also critical. Even though laminate is generally moisture-resistant, trapping moisture between layers can promote mold or cause the adhesive to fail. Proper acclimation of the new laminate and ensuring that the subfloor and existing laminate are dry is necessary.

Lastly, the installation method used for the new laminate might be impacted by the existing flooring. Floating floors, which click together without glue, are typically easier to install over existing laminate than glue-down types.

Steps to Properly Install Laminate Over Laminate

To achieve a successful laminate overlay, follow these essential steps:

  • Inspect and Prepare the Existing Floor: Thoroughly clean the surface, removing all debris, wax, or polish. Repair any damaged planks or replace sections if needed.
  • Check Flatness: Use a straight edge or level to ensure the existing laminate is flat within manufacturer tolerances (usually ±3/16 inch over 10 feet). Fill any gaps or low spots with a leveling compound.
  • Install an Underlayment: Even if the old floor has an underlayment, it’s recommended to add a new one designed for laminate installations to provide cushioning, moisture barrier, and sound insulation.
  • Acclimate New Laminate: Allow the new flooring to adjust to the room’s temperature and humidity for at least 48 hours before installation.
  • Maintain Expansion Gaps: Leave proper expansion gaps around the perimeter to accommodate natural movement of the flooring.
  • Use Transition Strips: At doorways or where the laminate meets other flooring types, install transition strips to protect edges and create a smooth transition.
