Guide to the laying of wooden floors: preliminary stages, conditioning materials, verification, preparation and laying down the floor
Preliminary stages of laying
We recommend installing the wood floor after you have completed all the works of the most important finishing, painting, electrical, windows, furniture structural, etc..
The packs of flooring must acclimate in a flat and horizontal. If possobile confezioi leave intact over the wooden packing (pallet) cutting metal strapping containment.
During transport, it is important that the packages are necessarily protected from the wind and from the weather.
Never use public transport without the adequate protections (such as open trucks).
Material conditioning
The parquet consists of wood fiber, is sensitive to changes in humidity and temperature and therefore, to avoid abrupt dimensional variations in the laid product, it is crucial to acclimate unopened packages in the environment of laying for 48 hours at a temperature of about 18 ° C and relative humidity of 60% (URA)
Warning: do not store the material in open environments, devoid of windows. The material must not be stored for a long time in construction sites where there are cements and plasters in the drying phase.
Verification of the material
Before laying submit items to a thorough examination in the light of the day, to be able to see visible defects or damage and also check color and texture.
Set the dry assembly of some of the panels in order to verify the suitability of the product.
Caution: Any material non-conformity, it must be installed.
The existing fabric and elastic floor coverings must be removed without leaving residue.
Preparation of the substrate
For what is not specified, it refers to the data described in DIN 18356 (hardwood floors) and DIN 18365 (floor coverings).
The preliminary measures must comply with the regulations and, in order to ensure a pose in a workmanlike manner, must be collected carefully all the information needed to avoid problems posed on the floor paying particular attention to the composition of the substrate and insulation.
The substrate must be dry and level to avoid the risk of cracking after installation of the planks. The maximum permissible tolerance of 2mm. height difference of 2.
We recommend using a straight edge from 2 m. resting on the substrate and to qualify the difference in the middle or to the side of the same. Greater height differences must be properly filled with appropriate materials.
Attention: Laying the floor on a regular foundation is not you risk cracking of the product, crunches, and increases the effect "rumble" due to the impact noise.
Polyethylene sheet
And 'essential to use polyethylene posed "a basin" in those places where you suspect ingress of moisture from the substrate or where the moisture content exceeds the recommended values.
This product should have a thickness of 0.2 mm. and a density of about 920 kg/m3 is always recommended in areas overlying a basement, garage, above ground floors and subfloors carpet; must be laid making sure to remove the junctions of about 10 cm sealing them with tape.
It 's always recommended vapor barrier when you are covering ceramic or stone.
Substrates of linoleum, vinyl, if in good condition, are sufficiently waterproof, for so the barrier is not required.
Warning: The vapor barrier does not remove the moisture from the substrate but avoids the ascent of residual or external.
Insulation jacket
The floating installation always requires the use of a guide in polyethylene foam of 2 mm thickness, in order to adapt to small differences on the substrate and to mitigate the effect of noise due to trampling.
Warning: The rough side of the sheath, it should be pointing toward the floor in wood, while the smooth side is in contact with the substrate. We advise you to apply a band at a time and lay the floor up to the almost total coverage of the same, then precede with another strip and repeat until the installation is completed. This will prevent damage to the sheath walking over them.
Do not lay the insulation over carpeted floors.
Above substrates heated, to allow a better efficiency of the heating, should not be used the sheath of polyethylene foam.
Before installing, make sure that the floor heating has been built in accordance with the requirements of DIN EN 1264 and DIN 4725 and that the floor is warmed up enough for the installation.
In the case of large surfaces, or where it suspects the presence of moisture, however, foresee the use of polyethylene vapor barrier.
The final inspection
Immediately after installation, the surface of the wood floor must be cleaned and inspected with particular attention to the immediate removal of the stains of glue (halos). The inspection must involve the end user (customer) and the installer, and must be done with people standing in the presence of natural light.
A source of angled light, artificial light or backlight, should not be used for the valuation and location of surface defects.
You can safely put down in a public place our hardwood floors.
