Definitions
- the present invention relates to a new coating, particularly monolayer, in the field of construction, as well as its manufacturing process and its use for coating and treating surfaces (exterior or interior) of buildings, especially facades.
- plaster, or mortar, used in facades allow the waterproofing and decoration of the outer walls (usually vertical or inclined).
- waterproofing prevents water from reaching the support (this also implies that the coating must not crack, must adhere to the support, etc.).
- the decoration includes, in particular, dressage (planing action), color and appearance (eg smooth, trowel, scraped, structured, washed, etc.).
- coatings there are different types of coatings (in particular coated monolayers or deposited in several different layers with generally separated functionalities, coatings of essentially mineral or organic type, etc.), each type of coating having specific properties and the choice of the coating generally operating according to different criteria (cost, function (s) sought, manipulation (manual or mechanical application), media to be coated, mode of application, geographical location, climatic conditions, height of the building, etc. ).
- monolayer plaster lies in the fact that it alone (in one or possibly several passes according to the particular aspect sought) ensures the functions of waterproofing and decoration, unlike other so-called "traditional" coatings for which, in order to obtain the same result, it is necessary to superimpose layers of different compositions with, in particular, more or less long drying times between these layers.

- the coating according to the invention is advantageously preserved in the form of a powder (for example in a bag of coating ready to be spoiled) before its use.
- the coating Prior to its deposition on a support, the coating is normally mixed with water and then deposited on a surface, for example a building facade.
- the surface or support to receive the coating is generally clean, healthy (not at risk of fragmenting or crumbling), dusted and dry. If necessary, it may have been previously treated (for example pickled, ragréée, washed, provided with renformis, caulking, etc.) for example to equalize the surface, to make it suitable for receiving the coating according to the invention, to seal cracks, participate in the insulation of the support, etc.
- the coating can be made by any method to obtain the desired thickness and appearance, for example by spreading the chosen coating or by projecting it with a compressed air device, etc.
- the application of the coating can be made if necessary in one or more (depending for example the desired thickness, etc.) passes, applied fees on charges or if necessary dried before deposit of the next.
- the drying of the coating according to the invention is advantageously uniform even if the support varies, thus avoiding color differences of the hardened coating.

- the coating or mortar may be cleaned, for example with water before drying or brushed after drying.
- the appearance conferred by the coating may be smooth or not, no additional treatment or addition of a finishing coating or additional film is necessary (the coating may however be provided with additional decorations such as paints, moldings, stamping or structuring, etc.)
- the coating produced can be left bare, can be colored in the mass (due to the presence of pigments in the coating), can also be structured (with particular surface effects), for example by striation, stamping, shoeing , creation of ribs, etc. especially at the level of the coating.
- the thickness of the final coating (after deposition and, depending on the desired appearance, possible scraping, etc.) is generally of the order of 8 to 20 mm, in particular of 10 to 15 mm approximately.
- the drying and optional reaction (crosslinking, hardening) of the coating or of certain components of the coating is generally carried out at ambient temperature (in particular between 5 and 35 ° C.).
- the present invention also relates to a support (or structure or substrate), such as a wall or building facade, coated, at least in part, with the coating according to the invention.
- the coating composition according to the invention and the reference composition are formed from the same basic mixture consisting of an approved mortar as defined in the EN 196-1 standard, said mortar being based on cement and sand (including aggregates).
- the reference coating and the coating according to the invention different in that in the reference coating, the previous base mixture is completed by 2 parts by weight of zinc stearate (per 1000 parts by weight of the base mixture ) as an additive with water-repellent effect, while in the coating according to the invention the base mixture is completed by 2 parts by weight (per 1000 parts by weight of the base mixture) of an aminofunctional polydimethylsiloxane of viscosity included between 200 and 40OcP (number of siloxane units of the order of 160) and having an amine number of the order of 0.15%.
