Wood Flooring – Advice For Laying Hardwood Flooring
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. Important note; flooring that is kiln dried to an 8% - 12% moisture level is ideal for the British climate and modern homes with any central heating systems that help to keep our humidity levels from approx 40 – 50%. Always ensure that the property has a good DPM in place and any air bricks are not blocked. You can create blockages for the moisture on the concrete to keep it at bay. You should be guided by the specialized advise of your fitter in making use of this.
A PU Primer can be used to solve the problem related to the moisture retention by attaching the hardwood flooring boards on the concrete base that has been dried 5. Most good flooring suppliers offer a wide range of adhesives for wood flooring and will help ensure you get the right one for the job. Another point to note is that the concrete has to be in a good state of repair i.e. Will not collapse or crevice from the surface. The unclean surfaces of the concrete must be cleaned with the help of primers so that there is better sticking. You must make use of the Leveling compound also if the newly laid wood flooring is not even.
Secrete nailing to Plywood / Chipboard or Batons/Joists
Always ensure that the sub base is securely fitted and a correct thickness is used. The Thicker the ply or chipboard the better always use the best grade available.
The sub floor has to nailed secretly with the help of the tongue and grooved timber where it can take in the secret nails from the tongue. It makes more space on the flush surface when the nail gets fixed at 45 degrees allowing more boards to be fixed with great ease. Porta nailer is the finest one to use for this work. The boards can be 165mm x 20mm width so that it can provide as much normal interchange as possible. With the help of glue or nail your fitter can affix the boards to either plywood or chipboard.
You can make use of 165mm x 20mm width for the solid wood flooring. 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. It isn’t recommended to use hardwood flooring boards as 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).One has to ensure that the the work being undertaken on the preexisting flooring must be evened out for any kind of bubbling and nails blown from inside the surface. On a ground floor were overlaying with a non-polythene vapor barrier is recommended. The present floor gets arranged with the new floor with the secret nail at about 90 or 45 degrees.
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. In order to control the expansion and contraction of the softwood floor one can make use of the plywood along with the new wood flooring.
All wood flooring will expand and contract over the course of the year. These boards tend to both shrivel as well as enlarge in winter and summer due to the absorption and the lack of the moisture accordingly. Inorder to bring down the extreme intersection it is Kiln dried to remove 8 12 moisture content.
There should be sufficient space as much as 15 to 20mm at the edge of the floor giving gap for any enlargement. Wood flooring pushes walls further out hence the places near the columns and fireplaces must be left. It is better to make use of the Cork strip to enable the movement of the board especially around the fire places and columns. However, solid wood flooring laid in winter will expand in the summer and may require additional expansion to be allowed for across the width of the floor.
Acclimatising wood flooring, the boards should be separated and laid loosely to enable the air to circulate around them. This procedure should be located in the area where it is to be installed to enable it to “acclimatise” or adjust its moisture content to correspond with its surroundings. Based on the conditions at the location of the laying of wood flooring and also the weather like summer has to be kept in mind before starting the work as temperature and humidity levels is high during this time.
