Pre Fitting Instructions
It is necessary that the flooring to be laid is left to acclimatise in the packaging (at room temperature) for at least 48 hours, lie horizontal and flat at the ideal relative humidity level of 45%.
The room should be dry, if the building is a new building with a concrete floor, wait until the floor is completely dry. The flooring should be laid at a minimum room temperature of 15c and a maximum of 22c.
The greatest possible care is taken to produce your floor. However, we advise you to check the boards for visible defects such as damage and deviations in shape or dimensions. No complaints regarding these visible defects will be considered after the boards have been laid. Make sure you have good lighting while laying the floor.
The Engineered 20mm thick flooring can be laid over a variety of surfaces (concrete, plywood, joists) and even over existing level wooden floorboards. Sub floor must be dry, level and with good load-bearing properties. Moisture content of floorboard subfloor should be 9% (with a tolerance of 2%). You should first check that there are no loose pieces, should any be found, these need to be screwed down.
If the base is concrete, its humidity should be less than 3% and the mortar should be evenly set. If the floor is to be laid in a new building, the rooms should be enclosed with the windows closed. All wet trades should be finished and the relative humidity in the premises should be between 40% and 64% - the humidity of the plasterworks and paintwork should be less than 5%.
The Engineered flooring is generally compatible with the most common water based under floor heating systems (check with your supplier for further details).
Floating Floor Installation
Alternative Installation Method – Fully bonded to sub floor
Engineered 20mm thick flooring can be glued directly to the chosen substrate. Preparation of the subfloor should be the same as above. A suitable flooring adhesive must be used and advice taken from your supplier.
When choosing to fully bond down onto the sub floor there is no need to glue the tongues of the boards with PVA. It is recommended that a flexible adhesive is used as this will reduce the stresses transferred to the subfloor by the natural movement of the timber floor.
Please seek professional advice before proceeding with this installation method as it is difficult to rectify any problems once the flooring has been laid.
Alternative Installation Methods – Secret Nailing
Where the subfloor is of wooden construction (joists, plywood, floorboards) the engineered 20mm thick flooring can be nailed directly to the subfloor. A suitable length flooring nail must be used in conjunction with a manual flooring nail gun ie. Porta-Nailer.
Please refer to the operating instructions of the chosen nailing apparatus for advice.
