The first thing to do when installing a vinyl floor is to thoroughly inspect the existing floor. Any bumps or irregularities in the subfloor will cause problems later on in the process. We therefore recommend taking plenty of time for a thorough preparation.
The type of subfloor, its quality and its preparation has a big influence on the final installation result. If the subfloor is not appropriate for the installation of Quick-Step Vinyl then necessary actions should be taken. Be aware that unevenness in the subfloor may leave marks and can create gaps in your Quick-Step Vinyl floor. The subfloor should be stable and firmly fixed. Furthermore it cannot be soft, damaged or loose laid/floating.
Do you have a wooden floor? Check for any traces of mould or insect infestations and make sure that the moisture content of the wood does not exceed 10%. If there is a crawl space underneath your wooden subfloor, contact a professional installer. He will be able to give you more information.
The ideal moisture content for a subfloor must be less then 2.5% CM if the subfloor is cement screed, and 0.5% CM if it is an anhydrite subfloor. If you have underfloor heating, these values should be reduced. Use a moisture meter and keep track of the moisture content.
Underfloor heating incorporated into the subfloor will not create any problems as long as the contact temperature does not exceed 27°C. Remember to switch off your underfloor heating 24 hours before and after installing your flooring if the floor- and roomtemperature is above 18°C. A Quick-Step Vinyl floor has a limited application with heating films and alternatives. For a good preparation, also read the separate installation instructions for floor heating.

It is absolutely essential that the subfloor is completely level. The preparation of the subfloor depends on what type of vinyl you are installing.
Use a levelling compound to smooth out any minor irregularities. Using the right underlay will help you overcome many problems.
We’re almost ready for the next step now. As soon as the subfloor is completely level, make sure that it’s also perfectly dry and clean. Remove all traces of grease, chemical residue and glue. Make sure that there are no stray nails left anywhere and sweep and vacuum the floor. We recommend removing your old skirting boards. As soon as the new vinyl floor is in place, you can install new skirtings
To summarise: before you start, make sure that your subfloor is level, smooth, clean and dry. This is the foundation for a good result.
