Floating Installation

Before Installation:

Floating installation.  It is imperative that the property is dry, warm and ventilated.  Sub-floor, plaster-work ad decorations should be thoroughly cured before the timber is delivered.
The sub-floor should be thoroughly dry with 2% moisture content maximum, the temperature should be between 16-23°C and the relative humidity between 50-65%.
The floor should be acclimatised withing the property for 2 days without underfloor heating or 5 days with underfloor heating.

Sub Floor

Concrete sub floor

The flooring can only be installed over a sub floor that is flat,  2 mm over 2 metres in any direction.  If you have any doubts over the level of the floor a quick drying screed can be used. The floor should be dry with no more than 2% moisture content.  With new concrete we would recommend using a liquid damp proof membrane (DPM).

Wood sub floors

The flooring can be installed over a sub floor that is flat, 2 mm over 2 metres in any direction and dry with no more than 10% moisture content.  If you have any doubts over the level of the floor you can over board the area with plywood sheets.

Installation

With both types of sub floor a high quality underlay should be laid.  When installing at ground level or onto a concrete sub floor cover the flooring with a PVC damp screen.  Or use an underlay hat incorporates a moisture retardant layer.  Seal all edges and joints with foil tape.  Check the walls for straightness with a laser or chalk line.  Unwrap one pack at a time and start to lay with the groove side against the wall using a 10 mm spacer to maintain a gap between the planks and the wall.  At this stage loose lay the planks and do not use any glue.

Lay the first row and use the cut from the end to start the second row, unless this is less than 20 cm.  Use a spacer for the second row to maintain a 10 mm gap from all walls.  Lay the second row checking the floor will run straight when you reach the center of the room.  The last boards of each run can be tapped into place using a pulling iron.  Use a tapping block to lightly knock the second row of boards into the first.  It is important to hit the tongue and not the edges of the boards.  Once the first two rows have been installed and you are happy with the position, take the boards apart and commence gluing.  Apply a good quality PVA glue to the underside of the tongue to minimise PVA getting onto the face of the boards.  The first two rows are crucial to the whole installation, it is imperative these are properly glued and straight.   Let the glue cure on the first two rows before continuing with the installation.  The last row of planks may need to be cut lengthwise and can be pulled tight using a pulling iron.

Cut through any architraves wit an undercut saw using an offcut as a guide.  Bore out any holes 10 mm larger than the pipes for any radiators so the wood can expand without damaging the pipe.

Please note that a constant humidity is essential to the well being of the floor.  Too much moisture in the atmosphere will call the wood to expand and spring.  Not enough will cause the wood to dry out and shrink.  Our wood is stored an a ambient temperature and humidity and your order will be dispatched at between 8-11% moisture content.  If after installation, the timber absorbs or discharges 1% in moisture content across the floor this could result in moment up to 2.5 mm per m2.

We can not emphasis enough the important of maintaining stable conditions throughout the lifetime of the floor.
