As a result of the increasing demand in this field, NET AZUR TRAITEMENT broadened its range of skills. That's why, we offer our services for carrying out of wooden floor sanding and the elaboration of protecting treatments.

Wooden floor sanding is necessary either after a new laying, or for a renovation because of wearing away and degradation, or for the willing of a customer to change the colour of his wooden floor. Generally speaking, an intervention is divided in two steps which are sanding and varnishing.


Before sanding, the operator has to be sure no metallic object is lying on wooden floors (nails...), liable to damage material. Then starts sanding stage. It can divided in three steps, indeed more, for a finer finishing. The first passage of the sanding machine is done with a coarse-grained disc. The following ones are made with finer-grained discs to refine sanding. This permits to make wooden floors flat and, in case of the presence of treatments, to remove them.

Sanding has to be done in the direction of floorboards for a straight wooden floor, or in the direction of light for a mosaic wooden floor.

Dusts are drawn up with a vacuum cleaner between each sanding. Edges and corners are sanded thanks to a sanding-edge machine.

This stage is ver important: wooden floors have to be extremely flat and out of any treatment.


After sanding, varnishing stage can start. It consists in laying a specific varnish, also called “vitrificateur”. It allows to reinforce the strength against agressions and time-wearing away of wooden floors, and to make their maintenance easier. Nowadays, products are mono-component, polyurethan based, offering strength and ease-of-use. The vitrificateurs are present in a wide range of tons, from white to dark-brown. 

Varnish laying is done in several times, two layers minimum. They are aqueous based, and have several finishing appearance (polished, satin or bright), under customer demand.

An other type of treatment can also be proposed : polish and oil laying. Polish consists in laying a “bouche-pore”, said “hard bottom”, for a better protection at the bottom of floorboards, then a special wooden floor polish and finally making shiny with a monobrush. Nevertheless, this treatment is less resistant then a polyurethan varnish, and is also costly, due to the propensity of wood to absorb (numerous layers necessary for an efficient treatment).
