Can I install Quick-Step vinyl on top of an existing floor?
The type of subfloor, its quality and how well it’s prepared have a big impact on the final installation result. If the subfloor isn’t suitable for installing Quick-Step vinyl, you’ll need to take the necessary steps.
Floating installation
For floating floors, the subfloor should be stable and firmly fixed. It also can’t be soft, damaged or loosely laid.
- The following floor coverings have to be removed: carpet, needle felt, cushion vinyl, floating laminate and timber, etc.
- Does not have to be removed: ceramic tiles, PVC, VCT, glued laminate and timber, fixed wood boards, etc.
- Does not have to be removed, but use of PE foil is mandatory to avoid migration: glued PVC, glued linoleum and glued oiled timber
In case of installation on a wooden subfloor, please remove any existing floor covering first. There should be no signs of mould and/or insect infestations. Make sure the subfloor is level and nail down any loose parts. Apply an appropriate wooden levelling board level floor or levelling compound on top for perfect subfloor preparation. The levelling boards must be fixed every 30 cm with screws.
The crawl space under the plank floor must be sufficiently ventilated. Remove any obstacles and make sure there is enough ventilation (minimum 4 cm² total ventilation openings per m² of floor). The moisture content of the wood must not exceed 10%.
