Your subfloor. The foundation of which your beautiful oak floor will be laid onto, and an important aspect that should be checked prior to the laying of your engineered oak flooring.

The subfloor should be clean. It should be scraped or sanded, swept and free of wax, grease, paint, oil and other debris. The subfloor should be flat with a maximum tolerance of 5mm over 3 metre, or 3mm over 2 metre. Failure to ensure this can have a negative impact on the installation of your oak flooring.

For concrete subfloors, the moisture content of the subfloor should be no higher than 4%. If the percentage is higher than this, the oak flooring is not ready to be laid. If a wooden floor is laid over a subfloor with a high moisture content, moisture will rise as the wet concrete dries, causing problems to your wooden floor.

For over underfloor heating systems, the system must be functional and working for at least 7 days prior to the floor installation. Stop the heating and let the floor cool down to ambient temperature for 3 or 4 hours before starting the engineered oak flooring installation. Immediately start the radiant heating system after the installation - taking special care that you don’t raise the temperature at floor level with more than maximum 5°C per day.
