A review of the site conditions for the levels of humidity from the atmosphere to the floor has to be done before starting the work. Added moisture to any solid wood flooring board can be problematic now and for much later on. The kiln dried boards can be kept dry from moisture when you make use of the breathable polythene membrane sheet that is placed below the dry plywood or chip board.
It is most ideal for usage in British homes when it has been kiln dried or 8 12 and for all the other homes it is suitable only when there is a central heating system to keep humidity at 40 50. You must make sure that the location does not have any air bricks that are hindered and also has good DPM. You can create blockages for the moisture on the concrete to keep it at bay. You should always talk to your expert fitter on the suitability of this.
Hardwood flooring boards can be glued to concrete bases that are dried to an approx 5% moisture level, a PU Primer can help with this Problem. You can very easily find wood suppliers that can help you with a wide range of adhesives for the wood flooring along with the one most suitable to you. One point to remember is that a proper quality of the concrete is very essential.e. not crumbling away or showing big cracks. If the concrete is dusty then Primers can be used to help key the surface for better bonding. If the engineered wood flooring is unlevel then we recommend using a Leveling compound solo.

Secrete nailing to Plywood / Chipboard or Batons/Joists
Always ensure that the sub base is securely fitted and a correct thickness is used. Try and ensure that the ply or the chipboard you want to make use of should be of a very good quality and gauge.
Timber which has tongue and grooved ends matched are ideal for secret nailing through the tongue and into the sub floor. The nail is fixed in such a manner that it is at 45 degrees and helps in the fixture of the next board very easily. Porta nailer is the finest one to use for this work. In order to provide as much natural movement as possible the boards should be wide enough and can be up to 165mm x 20mm. In order to keep the boards secured in one place your fitter may make use of either the plywood or the chipboard with the help of glue and nails.
For fixing the solid wood flooring boards you can utilize the one such as 165mm x 20mm wide one. One can get this by fastening the face of the floorboards into the sub-floor or batons. The secret nailing of the floorboards is done by this method and also identified as screw and plugging technique. One should not make use of the hardwood floor boards for the floating floors.
Fitting a new solid hardwood floor to an existing floor
Whether it be old flooring boards, sterling board, plywood or chipboard (chipboard does not hold a nail as other floor types and will need gluing and nailing).When fitting to existing floorboards these should be well fixed down, any high points sanded out and all nails punched below the surface. It is advisable to make use of the non polythene vapour barrier on the ground-floor. After this the new floor gets laid with the help of the secret nail at 90 or 45 on the already present floor.
Where, for aesthetic reasons, it is desirable to lay the new wood flooring in the same direction as the old floor a layer of at least 6mm grade plywood can be firmly fixed down and the new floor secret nailed with a nail long enough to penetrate the plywood and into the old floor. The newly laid wood flooring can be protected from any kind of increase or tightening with the use of plywood.
Expansion
All wood flooring will expand and contract over the course of the year. It is usual that these will tend to expand in the summer due to humidity and air being sucked by the boards and then get contracted in winter as the moisture gets dried from the boards. In order to bring down the extreme intersection it is Kiln dried to remove 8 12 moisture content.
One should keep a distance of a minimum 15 to 20mm from the rim of the floor for the board to increase. When undertaking this expansion it is essential that you leave the places near the columns and the fireplace due to the attribute of the wood to expand towards the walls. The most ideal thing to make use of near the fireplaces and the columns is the Cork strip that allows for its expansion and flexibility. You will have to make extra space when laying the solid wood floor in winter as it will certainly expand in the summer.
ACCLIMATISATION
Acclimatising wood flooring, the boards should be separated and laid loosely to enable the air to circulate around them. It is better to undertake the procedure in the place of installation as it will help it to get used to the moisture content present in that particular area. The fixture of the wood flooring can be done immediately if it is not summer as it is very hot and moisture content is high in this time along with an assessment of the site to be installed.
