Identifying your sub-floor
Your sub-floor is the floor beneath your floor or carpet. It is the structure over which your new flooring will be installed. If you already have a floor or carpet installed and you’re not sure what the sub-floor is, you will need to lift the existing carpet or floor to check.
The sub-floor can be the concrete foundation of your home, or the wood board or plywood fixed to the floor joists. The decision on which type of floor you can install, the accessories you need and the method of installation to use depends on your sub-floor.
You will need a clean, flat and dry sub-floor. ‘Flat’ means no more than 3mm variation up or down over a 3-meter span. Ensure the sub-floor is free of protruding debris or imperfections, failure to do this could lead to damage to your floor in the short or long term.
If you find you have an uneven floor, you can use screed levelling compounds on hard surfaces like concrete or plywood – these are available from most builders’ merchants. You could also use our 5.5mm fibre boards as an underlay to cover a rough surface.
Temperature and humidity readings of environment
Taking a temperature and humidity reading of the internal environment is a recommended step before acclimatising your floor. Keep these readings safe. If future problems do arise, then you will have a good benchmark which you can use to access the best way to deal with the issue.
Moisture testing and control
Ensuring that your new floor is properly acclimatised to the moisture conditions of the sub-floor and your home, office or shop is a vital part of a successful flooring installation. Concrete sub-floors will require a damp-proof membrane (DPM) to ensure they do not transmit additional moisture to your new floor once installed, this is due to their increased contact to the ground compared to wooden sub-floors. UK Flooring Direct have a Fast-Fit Polythene Damp Proof Membrane that is perfect for these floors. For an even easier installation, use our Cushion Ultra Silver Wood Underlay or Cushion Acoustic Gold Wood Underlay as they have a built-in damp proof membrane.
Under floor heating
UK Flooring Direct’s laminate, engineered and Luxury Vinyl Tile (LVT) floors are all compatible with underfloor heating, when used as directed with your chosen floors manufactures guidelines found in the box.
In general, all underfloor heating system should be installed and working correctly before any flooring installation can take place, a maximum surface temperature of 27⁰C should never be exceeded and all the heating should be switched off at least 2 days before you install a new floor. Once installed the heating must only be used in small increases of 2⁰C per day to allow the new wood floor to adapt slowly.
Always refer to your chosen flooring’s manufacturer guidelines for the final word on how to adjust your underfloor heating before and after installation.
UFH must not be used with UK Flooring Directs range of Solid Wood floors or any stick down floor.
