Can I install Quick-Step vinyl on top of an existing floor?
The type of subfloor, its quality and its preparation have a big impact on the final installation result. If the subfloor isn’t suitable for installing Quick-Step Vinyl, you should 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 must be removed: carpet, needle felt, cushion vinyl, floating laminate and parquet, etc.
- Doesn’t have to be removed: ceramic tiles, PVC, VCT, glued laminate and parquet, fixed wood boards, etc.
- Doesn’t have to be removed, but using PE foil is mandatory to prevent migration: glued PVC, glued linoleum and glued oiled parquet
If you’re installing on a wooden subfloor, please remove any existing floor covering first. There should be no signs of mould and/or insect infestation. Make sure the subfloor is level and nail down any loose parts. Apply a suitable wooden levelling board, floor leveller 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%.
