The method is characterized by applying a plaster layer on the surface to be coated; after a given time in which setting starts, tracing the desired pattern using a tool (1) guided by a tool guide (2) in order to remove plaster as defined by the contours of the pattern to appear in colour; preparing a plaster having the desired colour for the pattern surface(s); applying the plaster to regions of the pattern corresponding to the colour before setting of the first plaster layer; and removing the coloured plaster excess which has overflowed after setting of the coloured layer.

Description

La présente invention concerne un procédé de réalisation d'enduit à motifs décoratifs et les outils permettant la mise en oeuvre du procédé.The present invention relates to a process for producing plaster with decorative patterns and to the tools enabling the process to be carried out.

Dans l'art antérieur les enduits à motifs décoratifs étaient obtenus en peignant le motif sur l'enduit après que la prise de celui-ci ait été achevée. Une telle pratique a l'inconvénient de voir la couche de peinture, soit mal adhérer à l'enduit, soit se détériorer et s'éliminer dans le temps par manque de pénétration.In the prior art, plasters with decorative patterns were obtained by painting the pattern on the plaster after the setting of the latter was completed. Such a practice has the disadvantage of seeing the paint layer either badly adhere to the coating, or deteriorate and eliminate over time due to lack of penetration.

Le but de l'invention est donc de proposer un procédé de réalisation d'enduit à motifs décoratifs permettant d'avoir des motifs durables dans le temps, tout en conservant de bonnes propriétés d'imperméabilité pour la surface de l'habitation ou de l'immeuble recouvert d'un tel motif.The object of the invention is therefore to propose a process for producing plaster with decorative patterns making it possible to have patterns that are durable over time, while retaining good waterproofing properties for the surface of the dwelling or of the interior. building covered with such a motif.

Ce but est atteint par le fait que le procédé consiste

  • à déposer une première couche d'enduit sur la surface à revêtir ;
  • après un temps déterminé assurant le démarrage de la prise, à tracer à l'aide d'un outil guidé par un guide-outil, un motif souhaité pour enlever l'enduit selon les contours du motif devant apparaître en couleur;
  • à préparer un enduit coloré de la couleur souhaitée dans la ou les surfaces du motif ;
  • à déposer cet enduit coloré aux endroits du motif correspondant à la couleur avant durcissement de la première couche d'enduit et
  • à enlever le surplus d'enduit coloré qui aurait débordé après durcissement de la couche colorée.
This object is achieved by the fact that the process consists
  • depositing a first layer of plaster on the surface to be coated;
  • after a determined time ensuring the start of the setting, to trace using a tool guided by a tool guide, a desired pattern to remove the coating according to the contours of the pattern to appear in color;
  • preparing a colored coating of the desired color in the surface or surfaces of the pattern;
  • depositing this colored coating at the locations of the pattern corresponding to the color before the first coating layer hardens and
  • removing the excess colored coating which would have overflowed after the colored layer had hardened.

Selon une autre particularité, l'étape d'enlèvement de l'enduit avec l'outil est effectuée entre 30 et 60 minutes après la pose de la première couche.According to another particular feature, the step of removing the coating with the tool is carried out between 30 and 60 minutes after the laying of the first layer.

Selon une autre particularité, les enduits constituant chaque partie du motif sont préparés en même temps.According to another particular feature, the coatings constituting each part of the pattern are prepared at the same time.

Selon une autre particularité, l'enduit coloré est préparé après enlèvement de la première couche d'enduit dans les endroits souhaités et cet enduit coloré est additionné d'un accélérateur de priseAccording to another particularity, the colored coating is prepared after removal of the first layer of coating in the desired locations and this colored coating is added with a setting accelerator

Un autre but de l'invention est de proposer des outils permettant la mise en oeuvre du procédé.Another object of the invention is to propose tools allowing the implementation of the method.

Ce but est atteint par le fait que l'outil pour enlever la couche d'enduit selon les motifs est constitué d'un couteau dont la lame forme, avec une surface plane servant de surface d'appui sur un guide outil, une arche.This object is achieved by the fact that the tool for removing the coating layer according to the patterns consists of a knife, the blade of which forms, with a flat surface serving as a bearing surface on a tool guide, an arch.

Selon une autre particularité, l'arche a une forme trapézoïdale.In another feature, the arch has a trapezoidal shape.

Selon une autre particularité, l'arche a une forme elliptique.In another feature, the arch has an elliptical shape.

Selon une autre particularité, l'arche a une forme semi-circulaire ou en forme de U.According to another particularity, the arch has a semi-circular or U-shaped shape.

Selon une autre particularité, la lame présente, selon une direction perpendiculaire a la forme en arche, au moins un biseau (b) pour permettre l'éjection de l'enduit.In another feature, the blade has, in a direction perpendicular to the arch shape, at least one bevel (b) to allow the ejection of the coating.

Selon une autre particularité, la lame présente, selon les faces de l'arche, une légère dépouille (a) qui permet d'éviter le bourrage de l'enduit.According to another particularity, the blade has, according to the faces of the arch, a slight draft (a) which makes it possible to avoid stuffing of the coating.

Selon une autre particularité, le guide-outil est constitué pour des motifs rectilignes d'une règle formée de deux profilés en U espacés, d'une largeur correspondant a la largeur de l'arche du couteau, par au moins deux entretoises rendues solidaires des extrémités des profilés en U.According to another particularity, the tool guide consists for rectilinear reasons of a rule formed by two spaced U-shaped profiles, of a width corresponding to the width of the arch of the knife, by at least two spacers made integral with the ends of U-profiles.

Selon une autre particularité, la hauteur de l'arche est inférieure ou égale à la somme de la hauteur du profilé et de l'épaisseur de l'enduit.In another feature, the height of the arch is less than or equal to the sum of the height of the profile and the thickness of the coating.

Selon une autre particularité, dans le cas d'un couteau de forme trapézoïdale, le guide-outil comporte sur les faces des profilés en U orientés en vis-à-vis des lèvres pare-éclat.According to another particularity, in the case of a trapezoidal knife, the tool guide comprises on the faces of the U-shaped profiles oriented opposite the splinter-proof lips.

Selon une autre particularité, le guide-outil est constitué d'un anneau circulaire formé par deux profilés en U de forme circulaire et reliés entre eux par au moins deux entretoises.According to another particular feature, the tool guide consists of a circular ring formed by two U-shaped profiles of circular shape and connected together by at least two spacers.

Selon une autre particularité, le guide-outil est constitué d'un compas dont une des extrémités comporte un dispositif permettant la fixation du couteau.According to another particular feature, the tool guide consists of a compass, one of the ends of which includes a device allowing the knife to be fixed.

D'autres particularités et avantages de la présente invention apparaîtront plus clairement à la lecture de la description ci-après faite en référence aux dessins annexés dans lesquels :

  • la figure 1A représente une vue en perspective de l'outil formant le couteau pour enlever l'enduit et du guide-outil selon une variante de réalisation ;
  • la figure 1B représente une vue de l'outil associé avec une coupe selon BB du guide-outil ;
  • la figure 1C représente une vue en coupe selon CC de l'outil ;
  • la figure 2 représente une vue de face d'une façade revêtue d'un enduit portant un motif utilisant le procédé de l'invention ;
  • la figure 3 est une vue en coupe de la même façade.
Other features and advantages of the present invention will appear more clearly on reading the description below made with reference to the accompanying drawings in which:
  • FIG. 1A represents a perspective view of the tool forming the knife for removing the coating and of the tool guide according to an alternative embodiment;
  • FIG. 1B represents a view of the tool associated with a section along BB of the tool guide;
  • Figure 1C shows a sectional view along CC of the tool;
  • 2 shows a front view of a facade coated with a coating bearing a pattern using the method of the invention;
  • Figure 3 is a sectional view of the same facade.

Pour obtenir le motif de la figure 2, le procédé mis en oeuvre consiste à déposer sur la façade de l'habitation ou de l'immeuble brute (6) de maçonnerie, une couche d'enduit (3) de la couleur souhaitée. On enlève ensuite à l'aide d'un outil dont la description sera faite ultérieurement une partie de l'enduit déposé après avoir attendu un temps suffisant pour assurer un début de prise. Le temps pour assurer le démarrage de prise sera, par exemple, de l'ordre de 30 à 60 minutes selon les conditions climatiques et la nature du support (6).To obtain the pattern of FIG. 2, the process implemented consists in depositing on the facade of the house or of the rough masonry building (6) a layer of plaster (3) of the desired color. Then using a tool, the description of which will be made later, remove part of the coating applied after having waited sufficient time to ensure a start of setting. The time to ensure setting start will be, for example, of the order of 30 to 60 minutes depending on the climatic conditions and the nature of the support (6).

L'enduit est enlevé totalement ou partiellement aux endroits devant supporter le motif et selon une géométrie donnée par le guide-outil. Ainsi, avec un guide-outil rectiligne on peut faire un motif rectangulaire, tel que celui représenté à la figure 2 et comportant deux triangles dont les sommets se rejoignent au centre du rectangle. Dans cet évidement ainsi formé, on dépose, après l'avoir préparé, un deuxième enduit de même nature auquel a été mélangé un colorant. Le colorant sera de la couleur souhaitée pour le motif. Après que la prise complète de l'enduit (3) et des parties colorées (40, 41) ait été obtenue, le surplus d'enduit de teinte différente est retiré sur l'ensemble de la surface totale à l'aide d'une taloche grattoir. Une surface enduite est ainsi obtenue avec deux enduits de couleur différente déposés selon le motif préalablement tracé. Les parties de couleur (40, 41, 42, 43) sont coloriées dans la masse et assurent avec les parties non coloriées une prise parfaite garantissant une bonne imperméabilité de la surface enduite. Du fait que l'enduit encore frais a été retravaillé, les problèmes de retrait du second enduit coloré par rapport au premier sont éliminés.The coating is removed completely or partially at the places which must support the pattern and according to a geometry given by the tool guide. Thus, with a straight tool guide, a rectangular pattern can be made, such as that shown in FIG. 2 and comprising two triangles whose vertices meet at the center of the rectangle. In this recess thus formed, after having prepared it, a second coating of the same kind is deposited with which a dye has been mixed. The dye will be the desired color for the pattern. After the complete setting of the plaster (3) and the colored parts (40, 41) has been obtained, the surplus plaster of different tint is removed over the whole of the total surface using a scraper trowel. A coated surface is thus obtained with two coatings of different color deposited according to the previously traced pattern. The colored parts (40, 41, 42, 43) are colored in the mass and ensure with the non-colored parts a perfect grip guaranteeing good impermeability of the coated surface. Since the still fresh coating has been reworked, the problems of shrinking the second colored coating with respect to the first are eliminated.

Les outils de constitution des motifs pourront également être utilisés pour, par exemple, agrémenter la surface de gorges ou rainures mettant en valeur les motifs colorés. Pour ce faire, après avoir enduit la surface (3) et attendu un certain délai de prise, l'utilisateur emploiera l'outil d'enlèvement de l'enduit pour former les gorges (51, 50, 52, 53) entourant par exemple le motif. Cette gorge aura une section correspondant à celle du couteau destiné à enlever le produit. Il est également possible de réaliser cette gorge dans une zone (40, 41, 42, 43) enduite avec une couleur différente pour obtenir que ces zones de couleur différente soient en retrait par rapport à la première couche d'enduit (3).The tools for forming the patterns can also be used to, for example, decorate the surface with grooves or grooves highlighting the colored patterns. To do this, after coating the surface (3) and waiting for a certain setting time, the user will use the coating removal tool to form the grooves (51, 50, 52, 53) surrounding for example the reason. This groove will have a section corresponding to that of the knife intended to remove the product. It is also possible to make this groove in an area (40, 41, 42, 43) coated with a different color to obtain that these areas of different color are set back from the first coating layer (3).

Sur la figure 3, on voit que la gorge (51, 50) a une forme en U, ce qui laisse entendre que le couteau peut avoir également une forme en U. Par contre, sur la partie colorée (40, 41) les bords de la découpe sont verticaux, ce qui montre qu'un couteau à section carrée a été utilisé.In FIG. 3, it can be seen that the groove (51, 50) has a U shape, which suggests that the knife may also have a U shape. On the other hand, on the colored part (40, 41) the edges of the cut are vertical, which shows that a square section knife was used.

L'enduit coloré pourra être préparé juste avant son dépôt dans les surfaces (40, 41, 42, 43) où l'enduit (3) précédemment déposé a été enlevé après un temps de prise de 30 à 60 minutes et dans ce cas, en plus du colorant, on ajoutera à l'enduit coloré déposé en second un accélérateur de prise.The colored coating can be prepared just before depositing it in the surfaces (40, 41, 42, 43) where the coating (3) previously deposited has been removed after a setting time of 30 to 60 minutes and in this case, in addition to the dye, a setting accelerator will be added to the colored coating deposited second.

Une autre possibilité consiste à préparer les deux enduits colorés différemment en même temps, de façon à ce qu'ils soient au même stade de prise lorsque le deuxième enduit est disposé dans les parties évidées du premier enduit constituant les motifs à colorer.Another possibility is to prepare the two differently colored plasters at the same time, so that they are at the same setting stage when the second plaster is placed in the recessed parts of the first plaster constituting the patterns to be colored.

Les outils utilisés pour mettre en oeuvre le procédé sont constitués d'une part d'un couteau (1) pour enlever l'enduit et d'autre part d'un guide-outil (2) permettant le guidage du couteau pendant son déplacement. Le couteau est constitué d'une surface d'appui (10) horizontale. Une lame (11) est rendue solidaire de cette surface (10). Cette lame (11) a une forme, par exemple, trapézoïdale, ou elliptique, ou semi-circulaire, ou parallélépipédique, ou en queue d'aronde, ou encore en forme de U ou en forme de V, ou, comme représenté à la figure 1B, en forme de trapèze se prolongeant à la place de la petite base par un arrondi, ou encore toute autre forme qui pourrait être envisagée. La lame (11) comporte, comme représenté à la figure 1C, une forme en biseau formant un angle (b) sur chaque bord d'attaque du couteau. Les surfaces intérieures (111) du bord de la lame (11) sont inclinées par rapport à la surface externe (113) de la lame pour former le biseau. Ces surfaces inclinées (111) se prolongent vers le centre de la lame par une portion plane (112). Ce biseau permet l'éjection du boudin d'enduit coupé par la lame. Enfin, les bords d'attaque (114) de la lame sont compris dans un plan qui forme une dépouille d'angle (a) avec le plan perpendiculaire à la surface d'appui (10). Cette dépouille permet d'éviter le bourrage de l'enduit. Sur la surface d'appui (10) est soudée une cornière (12). Un manche (13) est rendu solidaire de cette cornière (12) par une extrémité et est pourvu à son autre extrémité d'une poignée (14) pour permettre à l'utilisateur de déplacer l'outil dont la lame (11) va découper et enlever l'enduit selon la courbe du guide-outil (2) sur lequel l'outil (1) appuie. Le guide-outil (2) est constitué pour les formes rectilignes de deux profilés en U (20, 21) reliés au moins à leurs extrémités par une entretoise (22), respectivement (23), en forme de cornière en L. Ces deux profilés (20, 21) sont espacés d'au moins une largeur (l) correspondant a la largeur de la base de l'arche (11) formée par la lame du couteau. Lorsque la lame (11) de l'outil a une forme trapézoïdale ou telle que celle représentée à la figure 1B, les profilés (20, 21) en U ont des faces situées en vis-à-vis qui se prolongent par des lèvres (210, 220) pare-éclat orientées vers l'espace intérieur de la règle et disposées dans un plan parallèle à la surface sur laquelle la surface d'appui (10) de l'outil (1) repose.The tools used to implement the method consist on the one hand of a knife (1) for removing the coating and on the other hand of a tool guide (2) allowing the knife to be guided during its movement. The knife consists of a horizontal support surface (10). A blade (11) is made integral with this surface (10). This blade (11) has a shape, for example, trapezoidal, or elliptical, or semicircular, or parallelepipedic, or in dovetail, or in the form of U or in the form of V, or, as shown in the Figure 1B, in the shape of a trapezoid extending in place of the small base by a rounded shape, or any other shape that could be considered. The blade (11) has, as shown in Figure 1C, a bevel shape forming an angle (b) on each leading edge of the knife. The inner surfaces (111) of the edge of the blade (11) are inclined relative to the outer surface (113) of the blade to form the bevel. These inclined surfaces (111) extend towards the center of the blade by a flat portion (112). This bevel allows the ejection of the plaster rod cut by the blade. Finally, the leading edges (114) of the blade are included in a plane which forms an angle relief (a) with the plane perpendicular to the bearing surface (10). This draft prevents the filling of the coating. On the bearing surface (10) is welded an angle iron (12). A handle (13) is made integral with this angle (12) by one end and is provided at its other end with a handle (14) to allow the user to move the tool whose blade (11) will cut and remove the coating along the curve of the tool guide (2) on which the tool (1) rests. The tool guide (2) consists for the rectilinear forms of two U-shaped profiles (20, 21) connected at least at their ends by a spacer (22), respectively (23), in the form of an L-shaped angle. These two profiles (20, 21) are spaced at least one width (l) corresponding to the width of the base of the arch (11) formed by the blade of the knife. When the blade (11) of the tool has a trapezoidal shape or such as that shown in FIG. 1B, the U-shaped profiles (20, 21) have faces located opposite which are extended by lips ( 210, 220) splinterguard oriented towards the interior space of the rule and arranged in a plane parallel to the surface on which the bearing surface (10) of the tool (1) rests.

La hauteur (e) des jambes en U des profilés (20, 21) est inférieure à la hauteur (h) de l'arche. Si l'on souhaite que le couteau (11) enlève la totalité de la première couche d'enduit d'épaisseur (x) déposée sur la surface, la hauteur (h) sera au moins égale à la somme de l'épaisseur (x) et de la hauteur (e) des jambes des profilés (20, 21). Dans le cas où l'on souhaite laisser une mince couche d'enduit sur laquelle vient se déposer la deuxième couche d'enduit coloré, comme représenté à la figure 3, la hauteur (h) sera inférieure à la somme de l'épaisseur de l'enduit et de la hauteur (e) des jambes.The height (e) of the U-shaped legs of the profiles (20, 21) is less than the height (h) of the arch. If it is desired that the knife (11) remove all of the first layer of plaster of thickness (x) deposited on the surface, the height (h) will be at least equal to the sum of the thickness (x) and the height (e) of the legs of the profiles (20, 21). In the case where it is desired to leave a thin layer of coating on which the second layer of colored coating is deposited, as shown in FIG. 3, the height (h) will be less than the sum of the thickness of the plaster and the height of the legs.

Il est bien évident que le guide-outil (1) a été représenté sous la forme d'une règle mais qu'il pourrait être réalisé sous la forme de tout autre objet permettant la création de figures géométriques telles qu'équerre, cercle. Le cercle peut être réalisé soit par une règle de forme circulaire comportant deux profilés circulaires reliés entre eux par des entretoises ou par un compas a l'extrémité duquel le manche (13) de l'outil est fixé. Dans ce cas, le manche (13) serait conformé pour avoir une orientation perpendiculaire à la surface (10) qui elle est parallèle à la surface à enduire.It is obvious that the tool guide (1) has been represented in the form of a rule but that it could be produced in the form of any other object allowing the creation of geometric figures such as square, circle. The circle can be produced either by a circular rule comprising two circular profiles connected to each other by spacers or by a compass at the end of which the handle (13) of the tool is fixed. In this case, the handle (13) would be shaped to have an orientation perpendicular to the surface (10) which is parallel to the surface to be coated.

L'enduit utilisé peut être du type de celui commercialisé par la société PRB sous la marque "PRB 85" ou "TRADICLAIR".The coating used may be of the type sold by PRB under the brand "PRB 85" or "TRADICLAIR".

Les colorants mélangés à l'enduit sont par exemple tous les colorants compatibles avec les enduits.The dyes mixed with the coating are for example all the dyes compatible with the coatings.
