General Product Informations

Randa Line’s Products

Wood is a natural “live” material, with differences in colour and fiber that make all the pieces different to each other. Wood is subject to change in size and colour due to external factors such as sunlight, temperature, humidity and daily use.

On delivery, the floor can clearly differ from the samples, but with air and light exposure, especially ultraviolet, all wood species can eventually change their colour (oxidation), tending to darken and conform to the characteristic colour of the specie. This color variation is more common and pronounced in exotic species. For this reason our advice is to avoid the floor’s covering with rug or carpet in the first period of time.

Due to contact with light and air, Doussiè may show strong differences in colour shades even between elements that were originally equal. Teak is variegated with natural differences in the colour shades, which tend to disappear after contact with light and air. Some wood species, mainly Iroko, Afzelia (Doussiè), Merbau, Panga Panga, Wenge may contain mineral concretions with a range of colors from white to yellow which are characteristic of each species. In some wooden species, especially Oak and Beech, some elements may show brighter streaks called “mirroring”. In the Cherry wood the presence of resin pockets or small holes is consistent with the characteristics of the species.

All the above mentioned characteristics are to be considered normal natural processes and in no way would constitute a cause for dispute.

Instruction for Storage and Handling

Products should be stored in a dry environment suitable for protecting wooden flooring, with the temperature between 10° and 25° C and humidity between 45% and 60%, far from heat sources and completely sealed. The packaging must be removed only at the time of installation, which has to occur once the windows already installed and the plaster is already dry.

Materials have to be handled with due care as they are very fragile products, especially next to any corners or joints Oil-treated flooring should not be stored in the warehouse for more than 30 days as the finishing could alter over prolonged storage.

Instructions for Laying

Laying has to be done only by qualified professionals. Unskilled workers can compromise the work and quality of the product.

Before laying a wooden floor, double check the suitability, compaction, level and sub-floor conditions. Also check the moisture content of the under-lay, the environment and the wood itself. Measurements must comply with the Regulations, and must be done using the appropriate instruments (carbide hygrometer for under-flooring, electrode-fitted hygrometer for wood).

When laying the floor, the ambient humidity must be between 45% and 60% and the temperature should not be below 10 ° C. The moisture content of the substrate must not exceed 2% of normal or quick drying cementitious screeds, 1.7% for heated screeds and 0.5% for anhydrite screed.

Different environmental conditions from those specified on the technical details can cause obvious cracks, flaws and micro-cracks (clefts). When dealing with heated screed pay particular attention to the specific procedures for laying on top of this type of sub-base. Before they become dry, adhesive residues should be completely removed from the pre-finished flooring with a special product.

Ventilate the Room (workplace) after laying.

Instructions for Maintenance and Cleaning

Maintain a temperature between 18° and 25° C and air humidity between 45% and 60% to avoid, or limit, the appearance of splitting, swelling and micro-fractures. The presence of water and other liquids and the high humidity could cause irreparable damage.

All the wood species normally used have sufficient hardness to ensure the required performance. Nevertheless, you can dent the floor with the impact of falling objects, the application of concentrated loads on small areas like heels, ladders and small objects such as nails or pebbles located under shoes. Do not load heavy weights on small portions of the floor to avoid localized failures.

Any varnish on the surface could eventually act as the floor’s protection, but does not prevent what has been described above. Over time, the varnish tends to become more or less opaque depending on the footfall intensity and general usage.
