A glue down installation will give you the best result of any type of install. It is our recommended and preferred method, and the one we use 90% of the time. Glueing a floor down to any level sub floor will result in a solid feel under your feet, and far less less movement. You must use glue down if you have a wet underfloor heating system.

It is vital that the conditions set out below are strictly observed, if not, it will be to the detriment of your hardwood floor.
1.1 Sub Floor
- Any sub floor must be smooth and flat to within +/- 3mm over a 3 metre radius
- Concrete sub floors must be sound and not loose
- Wooden sub floors must be sound and securely fixed
- Moisture content of wooden sub floors must be between 8-10 % and within 4% of your hardwood floor to avoid over expansion or contraction.
- Moisture content of concrete screeds must be no greater than 75% relative humidity
- A DPM must be incorporated below the screeded surface
1.2 General Site Conditions
- Air relative humidity should be at a stable point between 40-60 %.
- Moisture content of the walls must not exceed 8%
- Air temperature should be no less than 13°C and the general operating environment should be between 18°C – 24°C
- All wet trades such as plaster, terrazzo and floor tiling should be completed and dry before wood floors are installed.
- Windows must be glazed and outside doors hung before wood floors are installed.
- New buildings or extensions should be adequately ventilated and heated for at least 10 days before wood floors are installed.
- All radiator and water pipes should be subjected to a water test before installation of wood floors
- For floors fitted over underfloor heating, please see separate sheet relating to underfloor heating.
- All the door liners, architraves and doorstops will be undercut at the finished floor height to allow the flooring to be fitted beneath them with no visible gaps.
- All wooden doors, where necessary, will be taken down and trimmed to allow the doors to clear the new flooring. Once trimmed the doors will be re hung.
- Each board will be individually stuck down to the sub floor using MS Polymer adhesive. The adhesive is both solvent and water free, remains elastic when cured and is compatible with underfloor heating. The adhesive is applied to the sub floor with a suitably notched trowel and the individual hardwood boards are embedded in the adhesive.
- All cutting will be with a jig saw or a chopsaw.
- The boards will be laid to give a herringbone pattern in a variety of options
- An expansion gap will be maintained around the entire perimeter of the room to allow for the seasonal expansion and contraction of the floor. In general the expansion gap will need to be 1.5mm at each side for every metre of span. The expansion gap must not be filled and must be kept free of debris..
- This expansion gap will be covered by skirting boards.
- All other thresholds will be supplied and fitted where necessary in matching solid pre finished hardwood.
