Description
La présente invention concerne le domaine des procédés de pose de revêtements sur un support, notamment de pose de revêtements céramiques, ainsi qu’une composition pour la pose des dits revêtements.The present invention relates to the field of methods for laying coatings on a support, in particular for laying ceramic coatings, as well as a composition for laying said coatings.
Etat de la techniqueState of the art
La pose de carrelage ou de céramique sur les murs de pièces humides telles que les salles de bains ou douches nécessite actuellement l’application, sur les dits murs supports, successivement d’une sous-couche d’une composition assurant tout d’abord l’étanchéité à l’eau, puis, après séchage de cette sous-couche, l’application d’une couche de colle spécifique sur ladite sous-couche d’étanchéité, avant le placement des éléments de revêtement de type céramique.The laying of tiles or ceramics on the walls of wet rooms such as bathrooms or showers currently requires the application, on said support walls, successively of an undercoat of a composition ensuring first of all the waterproofing, then, after drying of this sub-layer, the application of a layer of specific glue on said sealing sub-layer, before placing the ceramic-type coating elements.
L’application de la couche de colle s’effectue généralement à l’aide d’un outil de type peigne, dénommé peigne à colle, qui permet au carreleur de répartir ladite colle sur la surface à carreler sous forme de lignes ou sillons parallèles, la pose du revêtement sur ladite colle venant alors « écraser » ces lignes de colle. Comme ces lignes de colle après « écrasement » ne sont pas nécessairement jointives, c’est-à-dire ne formant pas une couche de colle uniforme, il est requis de prévoir préalablement une sous-couche de protection à l’eau pour une utilisation dans les pièces humides.The application of the layer of glue is generally carried out using a comb-type tool, called a glue comb, which allows the tiler to distribute said glue on the surface to be tiled in the form of parallel lines or furrows, the laying of the coating on said glue then “crushes” these lines of glue. As these lines of glue after "crushing" are not necessarily contiguous, that is to say not forming a uniform layer of glue, it is necessary to provide beforehand a protective undercoat with water for use. in damp rooms.
Ceci nécessite la pose du revêtement en deux étapes, séparées par un temps de séchage de la sous-couche ; ce temps de séchage est généralement de 24 heures, obligeant le carreleur à revenir le lendemain pour poser le revêtement en appliquant un produit adhésif (colle du revêtement).This requires laying the coating in two stages, separated by a drying time for the undercoat; this drying time is generally 24 hours, forcing the tiler to come back the next day to lay the coating by applying an adhesive product (coating glue).
Ceci implique l’emploi de deux produits différents : d’une part une composition pour la sous-couche de protection à l’eau du support, produit qui après séchage donne un film continu présentant une certaine souplesse (déformabilité) et forme une protection à l’eau du support, et d’autre part une composition adhésive pour coller le revêtement. De plus l’emploi de deux produits différents génère des emballages, dont la tendance actuelle est de réduire leur nombre et leur poids.This involves the use of two different products: on the one hand, a composition for the water-resistant undercoat of the support, a product which, after drying, gives a continuous film with a certain flexibility (deformability) and forms a protection the water of the support, and on the other hand an adhesive composition to bond the coating. In addition, the use of two different products generates packaging, the current trend of which is to reduce their number and weight.
Buts de l’inventionAims of the invention
Un premier but de l’invention est de proposer un procédé plus simple de pose de revêtements sur un support, notamment de pose de revêtements céramiques, en particulier sur les murs de pièces humides telles que les salles de bains ou douches.A first object of the invention is to propose a simpler process for laying coatings on a support, in particular for laying ceramic coatings, in particular on the walls of wet rooms such as bathrooms or showers.
Un autre but de l’invention est de proposer un tel procédé de pose de revêtements plus rapide que les procédés mis en œuvre actuellement.Another object of the invention is to provide such a process for laying coatings that is faster than the processes currently implemented.
Encore un but de l’invention est de réduire le nombre et la quantité massique de contenants de produits pour la pose de revêtements, contenants qui sont généralement en matière plastique.Another object of the invention is to reduce the number and the mass quantity of containers of products for laying coatings, containers which are generally made of plastic.
Description deDescription of l’inventionthe invention
Dans la recherche de simplification de la pose de revêtements de sol ou muraux, les inventeurs ont mis au point un nouveau procédé de pose de revêtement et une composition pour la pose dudit revêtement.In the search for simplification of the laying of floor or wall coverings, the inventors have developed a new process for laying the covering and a composition for laying said covering.
A cet effet la présente invention propose un procédé de pose d’un revêtement, notamment un revêtement céramique, sur un support, au moyen d’une composition interposée entre ledit support et le revêtement, ledit procédé étant caractérisé en ce que la composition renferme un liant polymère organique (c’est à dire ne contenant pas de liant minéral), ledit liant comprenant la combinaison d’un agent de collage et d’un agent d’étanchéité et présente une viscosité comprise entre 1 et 5.106mPa.s, de préférence 1,6 et 2,8 106mPa.s (mesurée à 0,5 rpm/axe 95 au moyen d’un rhéomètre Brookfield modèle LVT) et en ce que la dite composition est appliquée au rouleau.To this end, the present invention proposes a process for laying a coating, in particular a ceramic coating, on a support, by means of a composition interposed between said support and the coating, said process being characterized in that the composition contains a organic polymer binder (that is to say not containing any mineral binder), said binder comprising the combination of a bonding agent and a sealing agent and has a viscosity of between 1 and 5.10 6 mPa.s, preferably 1.6 and 2.8×10 6 mPa·s (measured at 0.5 rpm/axis 95 using a Brookfield model LVT rheometer) and in that the said composition is applied with a roller.
La mise en œuvre d’une composition unique simplifie notablement les opérations du carreleur : ce procédé ne nécessite en effet l’usage que d’un seul type de matériau à appliquer (et donc d’un seul récipient sur le chantier).The implementation of a single composition significantly simplifies the operations of the tile setter: this process in fact requires the use of only one type of material to be applied (and therefore only one container on the site).
L’application de cette composition au rouleau est également plus aisée qu’avec un peigne à colle, et permet de répartir ladite composition en une couche continue entre le support et le revêtement, assurant ainsi une étanchéité à l’eau.The application of this composition with a roller is also easier than with a glue comb, and makes it possible to distribute the said composition in a continuous layer between the support and the coating, thus ensuring watertightness.
De plus, une seule couche étant nécessaire, aucun temps de séchage n’est à observer. La durée de pose du revêtement en est alors considérablement raccourcie.In addition, as only one coat is required, there is no drying time. The installation time of the coating is then considerably shortened.
Le procédé selon la présente invention est tout à fait approprié lorsque le revêtement est un revêtement céramique. Ce revêtement peut également être sous la forme de carreaux de faïence, de grès, de terre cuite ou encore des pierres naturelles, que l’on souhaite apposer sur un support tel qu’une paroi murale.The method according to the present invention is quite suitable when the coating is a ceramic coating. This coating can also be in the form of earthenware, sandstone, terracotta or even natural stone tiles, which one wishes to affix to a support such as a wall.
La viscosité de la composition mise en œuvre permet une application au rouleau de ladite composition selon l’invention sur un tel support. Ce rouleau peut être par exemple un rouleau comprenant un élément applicateur composé de fibres synthétiques tressées ou de mousse présentant une multiplicité d’alvéoles, en particulier d’alvéoles de type nid d’abeille. De tels éléments applicateurs permettent notamment d’augmenter l’emport de produit à appliquer.The viscosity of the composition used allows application by roller of said composition according to the invention on such a support. This roller may for example be a roller comprising an applicator element composed of braided synthetic fibers or of foam having a multiplicity of cells, in particular cells of the honeycomb type. Such applicator elements make it possible in particular to increase the carrying capacity of product to be applied.
Selon le procédé de la présente invention, la composition est avantageusement appliquée sur le support selon une quantité comprise entre 0,7 et 5 kg/m², en une couche unique, dénommée couche de collage et d’étanchéité, de préférence selon une quantité comprise entre 2 et 4 kg/m², mais peut également être appliquée en tant que pré-couche, dénommée couche d’étanchéité, de préférence comprise entre 0,7 et 1,2 kg/m2.
