GENERAL TERMS
Solid wood coatings contribute to sophisticated, cosy, joyful and relaxed environments. As a natural material it is also very resistant, durable, anti-allergic, nice and versatile. However, so as for all this to be applicable it is of the utmost importance that the following rules are respected:

1. PARTICULARITIES OF WOOD
Wood is a natural product which holds particular characteristics, varying in colour and texture, streaked darker, small closed knots, etc. Thus a choice prior to installation so as to combine the various tones in different rooms, if it is so intended, is recommended.

2. STORAGE AND HYDROMETRIC CONDITIONS AT THE PLACE OF INSTALLATION
Our Solid parquets are supplied with an average moisture of 9 +- 2%, which must be stored in a dry and ventilated location until the date of installation, never in a humid place, a stabilization of the material at the place of installation being imperative for a minimum of 1 week.
The openings to the building must be correctly closed so as to avoid the entry of dirt, water, excessive moisture and direct sunlight.
The installation must occur at a minimum temperature of 15ºC and at a maximum temperature of 22ºC. The relative moisture must not be inferior to 40% nor superior to 60%.

3. ADVICE / CONDITIONS FOR THE INSTALLATION OF THE FLOORBOARDS
3.1 GENERAL TERMS
» The counterface of the floorboards is to be waterproofed by means of a coating of insulation so as to ensure homogenisation;
» In ground rooms (1st floor above ground in detached houses), which are subject to high moisture levels it is advisable to waterproof the cement floor. It is brought to awareness that in such cases the type of wood to be used must also be selected, for not all types of wood are recommendable for installation under such circumstances.
» On cement floors containing Leca its waterproofing is imperative (the Leca absorbs and retains moisture coming from mortar, which is later sent to the parquet);
» Wood dilates under various climate variations and behaves differently from region to region. Subsequently a 4 mm gap on walls per linear meter is suggested, except for American oak for which a 7 mm gap is necessary. The gap should be distributed by all lateral walls;
» If where the floor is to be set, and after the complete closing of the work, an excessive moisture of the air is persistent, the use of a dehumidifier is recommended;
» Should there be the need to apply isolation or hardening products, repair paste or other on the screed before purchasing/using obtain information before the applicator as to the reference of the glue to be used on the gluing of floor or lath so as to foresee the use of compatible products  incompatibility of products will cause non-gluing of the floor or lath to the foundation. Obtain technical advice from supplier(s);
» After laying the floor there must be a stabilisation period of approximately 3 to 4 weeks before the refinishing and 1st coating and it must be duly protected against absorption of moisture from the environment;
» The final varnishing of the floor must be done up to a maximum of 3 months after its refinishing and 1st coating.

3.2. NAILED FLOOR
» The wooden slats on which the floor will be set must be distanced by 40 to 50 cm;
» Should there be an under-floor ventilation space it is recommendable that this is filled with cork particles or rock wool so as to ensure a better thermal and acoustic isolation as well as to prevent moisture from the concrete to reach the floorboards;
» To ensure a better acoustic isolation lath inlaid into the cement is recommended (absence of ventilation space between the screed and the floorboards);
» The setting of polyethylene canvas to avoid the rise of moisture from the screed to the floorboards is advisable.

3.3. GLUED FLOORBOARDS
» Use resistent glue (waterfree).
» The screed (support structure for the floorboards) must be regularised and not have a level of moisture which is superior to 2.5%. The total thickness of the screed should be considered and the level of moisture in it should be assessed at its deepest point so as to avoid the value to be superficial and for higher moisture to be found in its interior which shall reach the surface by means of a possibly slow drying process;
» In case of setting of floorboards which have been varnished during the production process the waterproofing of the cement floor must always be performed;

4. INSTALLATION ON RADIANT FLOORING
The wood on the place must be stabilised with the final environmental conditions (minimum of 3 weeks). The advisable wood moisture is of 7 to 9% for which if the drying of the wood is not possible for these values, a wider stabilisation period must be considered.

GENERAL RECOMMENDATIONS:
» Do not use wood which is too sensitive to moisture and use greater density wood as these possess a greater thermal conductivity;
» The Thermal Resistance on Wood Parquet must be inferior to 0.15 m²K/W ;
» The maximum recommended temperature from the radiant heating system is 28ºC at the surface of the base of the foundation.

SUPPORT CONDITIONS:
» The heating system must be activated at a medium power (30ºC) from two to three weeks and shut-off a day or two before the beginning of the installation. Once the parquet is applied the temperature must suffer a 3 to 5ºC increase per day;
» The minimum thickness of the mortar above the heating piping is 30 mm;
» The moisture of the screed must be inferior to 2%;

5. PRESERVATION – MOISTURE AND ROOM TEMPERATURE OF THE HOUSE
Excessive temperature and moisture variations within the house may cause changes to the applied wood, namely, fissures on the joints and/or the considerable increase of the parts causing the bending/detachment of the coating.
The parquet must be protected from direct sunlight by means of glass surfaces so as to avoid strong discoloration/oxidation and fissures on the wood.
The room temperature must range between 20 and 40ºC and the Relative Moisture between 40 and 60%. These values are ideal for both the wood and the health of the inhabitants.
Thus the control of these gradients is recommended in order to ensure the balance between moisture and room temperature.

6. MAINTENANCE RECOMMENDATIONS
Once applied, the parquet must be protected so as to avoid damage which may diminish its quality or finishing, the following care requires consideration:
» In case of furniture moving the direct contact with the parquet is to be avoided in order to prevent the scratching of the varnish;
» The fall of heavy and pointy objects on the parquet is to be avoided for these may cause dents on the wood;
» For daily cleaning a floor mop and a BONA Care cleaning product should be used;
» For more intense cleaning BONA Care and BONA Refresher products should be used;
» Never use cleaning products containing ammonia, water or other abrasive detergent on wooden floors for these shall damage the finishing and the floor itself.

RETURNS/COMPLAINTS
Upon the reception of the material, the client must inspect it to ensure its conformity.
Should the product not correspond to the required specifications, a complaint and/or return of the material must be addressed to Madeicentro up to a maximum of 8 days from the issuing of the Shipment Form/Bill of Lading and/or Invoice.
If, upon laying the floorboards any changes to the requested specifications are noticed (regarding the visual or dimensional characteristics of the product), it should immediately be rejected and Madeicentro informed toward the verification of it. In case the product has already been laid, Madeicentro will not accept a complaint.
Madeicentro will be held responsible for any deficiency on the wood which occurs during these reception periods, as well as for any deficiency deriving from faulty laying and deficient installation or environmental conditions at the place of use.
The returned material must be defect-free (dents caused by handling at the construction site or transportation; excessive moisture and must be packaged in the same manner as that of the supply;
The complaint must be addressed to Madeicentro in writing claiming the grounds for non-acceptance and the returned material must include the Return Note.
Returns derived from excessive quantity shall not be accepted.

In case of doubt or need for additional clarification do not hesitate to contact us. We will be happy to offer all our support.
