Must The Sub-Floor Be Completely Even

Some irregularity can be tolerated on the sub-floor when fitting any wooden floor with any installation system.

However, the tolerance will likely be different depending on the installation system used. The general rule would be a variation of ±3mm over a 2 metre length, but please check the specific installation instructions for the method chosen. The best way to test is to take a board and lay it on its edge so you can see any peaks or troughs. If either happens to be outside of the parameters some sub-floor preparation will need to be applied.

Remember that the finished flooring type can only be as good as the installation allows. We would always recommend that, for any installation type, the sub-floor preparation is vital and irregularities should always be corrected as opposed to finding another way around the problem.
