How to install laminate on an existing floor?
Yes, it's entirely possible to install laminate over an existing floor! The exact installation method depends on which floor you want to install your laminate upon. Follow the steps below to ensure a smooth installation process.
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 (non-foamed/ non-cushioned vinyl, linoleum, etc.) doesn't have to be removed but a Quick-Step levelling underlay should be installed on top of the existing floor covering. Of course the flatness rules that are explained in our installation instructions need to be followed correctly.
On a wooden subfloor
When you have a wooden subfloor, you have to remove every existing floor covering first.
Important:
- 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.
- Always use a Quick-Step underlay (including damp-proof membrane on a mineral subfloor)
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.
