Can Quick-Step Laminate be installed on top of an existing floor?

Yes, this is possible. The exact installation method depends on which floor you want to install your laminate.

On a damp-porous floor covering

First remove any damp-porous floor covering (i.e. carpet, needle felt, etc.) before installing the Quick-Step Laminate. 

On a damp-sealer floor covering

Damp-sealed floor covering (PV, linoleum, VCT, etc.) doesn't have to be removed but a Quick-Step levelling underlay should be installed. 

On a wooden subfloor

When you have a wooden subfloor, you have to remove every existing floor covering first.


  • No signs of mould and/or insect infestations should be present.
  • Make sure the subfloor is level. Any unevenness greater than 4 mm over the length of 2 meter must be smoothed out. The same applies to any unevenness of more than 1 mm over a length of 20 cm. This rule does not cope to national regulations about levelling.
  • Nail down any loose parts.

When you have an uneven timber floor, you must install the Quick-Step underlay Thermolevel. Also, there must be sufficient ventilation in the crawl space underneath the timber floor. The moisture content of the wood must not exceed 10%. Install the new floor at ninety degrees to the existing subfloor.
