INSTALLATION GUIDE

FLOOR ADHESIVE METHODS

The flooring is glued to the underfloor: ideal for all sizes of parquet. A special spatula is used to spread the glue into a thin even layer. The flooring is glued to the underfloor: ideal for all sizes of parquet. A joint along the entire perimeter of the room allows the natural dilation of wooden floors caused by changing in hygrometric conditions.

LAYING OF PREFINISHED FLOOR USING ADHESIVE METHODS

Special glues are used for prefinished floors as the boards are pre-varnished and as such do not require corrective interventions. When using this method, cleaning is essential while the prefinished products are being processed because any residual adhesive could affect the varnished material.

FLOATING METHOD

The flooring is laid on the ground, on top of a special underfloor (expanded polyurethane, cork etc.). Ideal for laying large three- layer boards, it also guarantees great acoustic insulation and is an anti-humidity barrier. When using this laying method, it is vital for the slabs to be perfectly flat to prevent any movement of the boards or a hollow sound. Suitable only for certain types of prefinished floors with elements that slot together. The boards are laid by placing them on a levelled underfloor and an acoustic insulating layer. The elements are fixed together by a thin layer of vinyl adhesive between the slot-in areas or using other mechanisms.

OUTDOOR DECKING METHOD

Corà supplies pre-assembled boards, which have undergone anti-fungus treatment, along with plastic supports. Oiling is recommended for maintenance work later on.

LAYING ON FLOOR HEATING ELEMENTS

This method consists of laying the boards on cement blocks perforated by tubes carrying a liquid that is able to heat the area through the floor instead of using radiators. Generally speaking, all wood species can be laid over floor heating elements; mahogany and stable wood species, however, should be small in size (do not use woods such as maple, beech or larch). Prefer thinner floors, as wood is a thermal insulator. Before commencing the laying process, the heating system should be switched on and brought to its maximum temperature, increasing it by 10°C a day, and maintained at maximum temperature for 10 days; then it should be cooled to a temperature of 20 °C for an additional 5 days. This operation will guarantee stabilisation of the blocks. Now switch off the system and start laying the floor, which can be installed using either the adhesive or floating methods, after measuring the humidity by means of a carbide test. On completing the installation, switch on the heating system and bring it to its maximum temperature progressively.

For daily cleaning, an antistatic cloth or an electric broom with the special parquet spout is sufficient.
For deep cleaning just water mixed with a specific product for cleaning parquet.
avoid the use of aggressive detergents or ammonia which can compromise the brightness.
It is not necessary to use paints but a special parquet oil, distributed with a brush or a rag one or more times a year depending on the needs, guarantees unmatched durability.
If you use some precautions, such as a doormat at the entrance to avoid bringing pebbles into the house that could damage the wood, the parquet does not require maintenance. Only after many years, and in case of wear, it may be necessary to intervene with a partial or total spot bore.
