Installation and Maintenance

Storage
Parquet must be stored, in its original packaging, in a perfectly dry room not subjected to condensation or rising damp.

Environmental conditions and under-flooring (screed)
Wood is a natural fiber sensitive by nature to climate condition changes. Depending on the conditions in which it is laid, different reactions may result. In particular, wood is affected by changes in humidity causing dimensional changes. An optimal installation is achieved in environmental and under-flooring conditions free of humidity that must be previously verified to avoid problems such as shrinkage (slits) or swelling.

The measurement of the moisture content of the laying surface (concrete or anhydrite screed) is performed with a special instrument, hygrometer electric or carbide. The humidity of the underflooring in the case of cement screed must not exceed 1.5 to 1.7% and 0.2% in the anhydrite screed. The room temperature should be between 18 ° and 25 ° C and room humidity between 40% and 60%. Maintaining these values is also advisable for our health.

It is essential that the environments are acclimated, that is with all doors and windows installed and with the painting done and dry.

The eventual conservation of your wood flooring depends mainly from a healthy and balanced environment. Generally at home the control of humidity is neglected. In winter the functioning of the heating system generally determines a very dry climate which in wood results in shrinkage, while in summer specially in presence of coolers (not conditioners) a very humid climate may be determined with a consequent tendency to wood swelling. It is therefore essential that all necessary precautions are made as to avoid that critical conditions for your parquet are established.

Under-flooring
The cement or anhydrite screed is the support on which the wood flooring is installed. Before installation some important testings of the screed quality are to be done.
Uniformity: the screed must have a uniform thickness in all its extension as to avoid slits and cracks;
the surface must be perfectly clean, flat and smooth.
Compactness: the screed must be compact, the surface must not create dust or peel.
Thickness: the thickness must be sufficient as to guarantee rigidity and resistance. For example a good cement screed has a thickness that goes from 4 to 7cm while an anhydrite screed has a thickness from 2,5 to 5cm.
Seasoning: each screed needs the right time to harden and season as to reach its hygrometeric balance.

Other laying sufaces
Pre-finished parquet is particulary adapt to be laid on pre-existing floors such as tiles, ceramics, marble. To lay on these surfaces it is necessary to carry out due precaution, using specific products and tools.

Types of Installation

Glued
This type of installation, suitable for consistent and well leveled under flooring (screeds), involves the use of two-component or single component polyurethane adhesives. The glue is spread on the screed to glue the boards.

Floating
This type of installation is only performed with three-layer flooring because its structure provides greater stability. The installation includes the laying out on the under flooring of an acoustic insulation mat generally polypropylene, these mats come in different densities in relation to the isolation that is required. The elements are connected by a thin layer of moisture-resistant glue applied to the female joint of the plank. This type of installation is suitable for any kind of under-flooring and is useful if you want to change the floor without removing or damaging the existing one.

Installation on under-floor heating
Parquet is suitable for this type of under-flooring as long as you meet certain criteria:

  • Thickness of the planks must not exceed 15 mm;
  • Use wood species recommended for this type of installation;
  • Ideal is glued installation , but the glue used must be suitable for this type of installation;
  • In case of floating, we recommend using a specific under-floor mattress because it is fundamental to minimizes the resistance to thermal conductivity;
  • We recommend to not exceed 28° C on the surface of the parquet.

Complete the curing of the screed and after verifying its moisture, proceed to the heating of the under-flooring for at least 2 to 3 weeks gradually increasing the temperature until it reaches operating temperature. The cooling process must be done by gradually reducing the temperature. Before laying the floor, the heating must be switched off for 4-5 days.
After installation, the system can be put into operation by increasing the temperature gradually.

During the winter, when the heating system is on, to avoid slits in the parquet, we recommended to monitor the air humidity by checking it goes from 40 to 60%; in case the values are lower you may use a humidifier as to correct humidity values.
