Can I install a timber floor on top of an existing floor?
Yes, you can install a wood floor over an existing floor. The exact installation method depends on which floor you want to install your timber on and which installation method you’re choosing.
In the case of gluing, the existing floor covering must be completely removed.
For floating floors, remove any moisture-permeable floor covering (carpet, needle felt, etc.) first. There’s no need to remove existing moisture-resistant floor covering (non-foamed/ non-cushioned vinyl, linoleum, etc.). Always use an underlay. We recommend using a Quick-Step underlay.
In case of installation on a wooden subfloor, please remove any existing floor covering first. No signs of mould and/or insect infestations should be present. Make sure the subfloor is level. Nail down any loose parts. If your plank floor is on the ground level, lay a plastic foil first. Apply a levelling floor on top of this.
For a perfect subfloor preparation, it’s recommended to lay a Quick-Step underlay on top to level out any unevenness between the planks. Install the new floor at ninety degrees to the existing subfloor. The crawl space under the plank floor must be sufficiently ventilated. Remove any obstacles and make sure there’s enough ventilation (minimum 4 cm² total ventilation openings per m² of floor). The moisture content of the wood must not exceed 10%.
