Definitions

  • the invention relates to a process for producing a decorative pattern coating.
  • the invention relates more particularly to a process for producing a decorative patterned coating by stamping.
  • a first object of the invention is to provide a process for producing decorative patterned coatings overcoming the disadvantages of the prior art cited above, which is easy to implement.
  • the method according to the invention may advantageously be in accordance with one of the secondary claims 2 to 17.
  • a coating layer (1) is deposited on the surface (2) to be coated.
  • the coating can be applied directly, for example, to concrete or masonry, brick, plots or stone.
  • the method can be applied to an exterior or interior surface.
  • the deposit of this coating layer can be performed by spraying with a machine or manually
  • the thickness of the coating is used, on the outside, to provide on the one hand a decorative effect and on the other hand impermeability , while inside, it is mainly decorative. For a good impermeability, a layer of 10 to 15 millimeters of coating can be deposited.
  • the coating can also be deposited on a smaller thickness in the case where the impermeability is not sought (example: the case of a concrete wall). Indeed, a coating thickness of the order of 4 to 5 millimeters only is necessary to achieve the decorative appearance of the invention.
  • the matrix may consist of a rigid or semi-rigid plastic sheet (3) of small thickness and having a low weight per square meter.
  • the thickness of the sheet is 5/10 to 1 or 2 millimeters for a weight per square meter of 100 to 600 g / m 2 .
  • the matrix can be made for example from a polystyrene sheet. Other materials, such as polyurethane or polyethylene can be used.
  • the decorative patterns can be made by thermoforming or by stamping sheets or plastic roll.
  • the matrix may also consist of a laminated cardboard sheet.
  • a plastic film of very small thickness, such as, for example, a polyethylene film, is for example glued on the surfaces of a sheet of cardboard. The complex thus formed is then stamped to form the decorative patterns.
  • the matrix comprises on a first of its faces, said face-face (4), the raised pattern (6) and on the second face, said reverse side (5), the hollow pattern (7).
  • the pattern is constituted by reliefs (8) on the front side and by grooves or cavities (9) on the reverse side.
  • the reliefs (8) forming the pattern, and arranged on the front face (4) have a depth (P) of between 3 and 8 millimeters and a width (d) of between 3 and 15 millimeters.
  • the reliefs (8) may have clearance angles (x) of at least 5 °.
  • the dimensions of the matrix may vary depending on the size of the area to be decorated and the type of pattern.
  • the weight of the matrix and the dimensions of the patterns make it possible to manually manipulate and use in the process according to the invention, matrices of several square meters.
  • the decorative patterns made on the plastic sheets can be multiple. These patterns may for example be geometric patterns and / or represent different types of imitation, wooden board imitations representing the veinings and knots of different wood species as well as grooves between each board, patterns of imitation of weaving as shown in Figure 4, bricks, tiles, stones, paving, leaves, earth, etc.
  • an embossing stamping can then be performed.
  • the stamping takes place almost instantaneously when the coating is no longer sticky to the fingers.
  • the coating layer has been deposited, it is necessary to wait a fixed time, said frozen, before applying the matrix.
  • This freezing time is between 10 and 60 minutes, depending on the climatic conditions and the compactness of the coating.
  • the matrix (3) is applied to the fresh plaster layer (1) which is still malleable, the front face (4) of the matrix comprising the reliefs (8) being oriented towards the coating layer (1) and pressed thereon.
  • the low weight of the dies makes this operation easy.
  • the pressing operation of the matrix on the coating can be carried out by means for example of a brush, a smooth roller, a trowel or a trowel. Due to the size of the patterns (6), the inlay of the patterns is done without any difficulty. As soon as the pressing operation is completed, the matrix is removed, the decorative patterns are obtained on the coating on the surface.
  • the relief angles (x) of the reliefs (8) of the matrix and the low coefficient of adhesion of the material of the matrix on the coating avoiding the suction effect facilitate the removal of the matrix, without alteration of the inlaid pattern .
  • the recessed patterns made on the plaster layer can then, after drying, be completely or partially filled with a different color coating, for example by means of a trowel. This coating of different color can also be applied directly, after the removal of the matrix, before the drying of the coating layer, by overflowing on the coating layer. When both coatings begin to harden, a scratch of about 3 mm of plaster is made.
  • Embossing, or molding, as shown in Figure 6, can be achieved using a matrix similar to that used previously. Cavities or grooves (9) constituting the recessed pattern (7) of the back side (5) are filled with plaster. This filling plaster (10) may be identical to that deposited on the surface to be decorated or of different color depending on the desired decorative appearance.
  • the matrix (3) is applied directly to the fresh coating layer (1), the back side (5) of the matrix being oriented towards the coating layer (1).
  • the matrix (3) is maintained applied to the coated surface for a period of 4 to 5 hours corresponding to the end of the setting of the coating layer (1) and the filler (10).
  • the application time is determined according to the atmospheric conditions and after drying, the matrix is removed.
  • a surface condition similar to that of the stone, imitating for example the tufa, can be obtained by an inlay stamping by means of a semi-rigid matrix having reliefs forming irregularities and inlays imitating the appearance of the stone.
  • the reliefs have, for example, heights of 0.1 to 6 millimeters.
  • Figure 7 shows a view of the surface appearance of such a matrix (15).
  • Figure 8B is a schematic perspective view of the die and Figure 8A is a cross sectional view (AA ') illustrating the irregularities of the die surface (16).
  • a plaster layer is deposited on the surface to be coated (Fig. 9A).
  • the matrix is applied to the coating layer ( Figure 9B).
  • the matrix can be removed as soon as the pressing operation is complete (Fig. 9D).
  • the matrix may include a flange for gripping and facilitate handling during stamping.
  • the step ( Figure 10a) of depositing the plaster layer is followed by a step ( Figure 10b) of aggregates projection (18).
  • This projection operation is performed on the fresh coating layer, immediately after its application. It can be realized manually or mechanically using a machine (19) to be sprayed.
  • the projected aggregates may be of organic or mineral nature, such as silica, limestone, marble, microfiber, plastic for example.
  • a semi-rigid matrix similar to that described above with reference to FIG. 8A, having reliefs of 0.1 to 6 millimeters, forming irregularities imitating the appearance of the stone, can be applied to the layer (2) of fresh plaster.
  • the matrix is then pressed (FIG. 10D), for example using a roller (17), and is removed (FIG. 10D) as soon as the pressing operation is completed.
  • the application of the matrix on the coating makes it possible to embed the aggregates in the coating by driving back towards the aggregates, the coating of the edge of the hole caused by the projection of the granulate, without covering it, as a crimping.
  • the use of the matrix according to the invention makes it possible to obtain perfectly apparent aggregates. Thanks to the reliefs present on the surface of the matrix, the stamping according to the invention makes it possible to prevent the aggregates from being embedded in the coating, contrary to the technique used in the prior art.
  • the existing technique consisted in driving the aggregates by means of a trowel. When removing the trowel, the coating sticks to the trowel by suction effect, and coats aggregates. The use of the method according to the invention eliminates this suction effect.
  • the matrix applied to the coated surface preferably consists of a flexible plastic sheet.
  • the reliefs consist of aggregates of different particle sizes bonded to one of the faces of the sheet.
  • the aggregates can consist of silica, limestone, expanded polystyrene beads, plastic ...
  • the aggregates are glued to form a granular surface with irregularities and incrustations.
  • the matrix is applied, by means of a brush for example, on the fresh coating.
  • the matrix is then removed.
  • the sheet of plastic can be packaged as a roll.
  • the matrix is unwound and applied directly to the coated surface, for example from top to bottom.
  • the sheet is cut according to the length of the necessary matrix.
  • Several patterned leaf lais can be placed side by side. When the patterns have symmetry, positioning marks are provided on the back of the sheet.
  • a matrix made of a rigid or semi-rigid plastic sheet may also be used.
  • the matrices consisting of rigid or semi-rigid sheets, as described above, are pierced with perforations of small diameter in order to remove air between the plaster and the matrix at the time of application thereof .
  • the dies may also be made of a transparent material.
  • the transparency of the matrix makes it possible to verify visually the quality of the pressing before the removal of the matrix.
  • embossed stamping the transparency of the matrix makes it possible to check whether the filling compound has sufficiently hardened to allow removal of the matrix.
  • the transparency can also be used during the application of the matrix to visualize positioning marks previously made on the coating layer. These marks may be constituted by small recesses formed by the operator which disappear during the pressing operation of the matrix. In the case where a scraping operation is provided after stamping, the markers may consist of color traces that will be removed during scraping.
  • the matrix may consist of a roll with relief.
  • the patterns (12) desired are then made in relief on the surface (13) of the roller (11) held by a handle by the user.
  • the reliefs constituting the patterns have a maximum depth of 8 millimeters, a width of between 3 and 15 millimeters, and draft angles greater than 5 °.
  • the roll is applied to the plaster layer (1) by interposing a plastic film (14), polyane type, so as to to avoid the adhesion of the coating on the roll to achieve the patterns inlay on the coated surface.
  • a plastic film (14), polyane type Such a roll can be made of molded plastic.
  • the polyane film (14) of a few tenths of a millimeter can be drilled to release the air between the plaster layer (1) and the film (14). The film is then removed 5 to 30 minutes depending on the weather conditions.
  • a parallelepiped plate having the patterns in relief on one of its main faces, can be used to replace the roll described above.
  • the dimensions of the plate are adapted to be able to achieve the patterns by incrustation on the coated surface by holding the plate with both hands.
  • the plate can be made of molded plastic. These two types of matrix are particularly intended for non-professional uses.
  • Positioning marks may be made on the dies in order to properly position the dies relative to each other during the production of the patterns.
  • the material used to make the coating must be smooth and sticky to allow it to pass through a spraying machine and must remain soft for a moment to allow for stamping. In addition, it must have good cohesion to remain cohesive when removing the matrix.
  • the material used is formed from rolled siliceous granules and a binder consisting of a mixture of aerated lime and cement. Optimizing the overall grain size of the coating prevents particles smaller than 80 microns from rising to the surface and giving the surface a shiny appearance.
  • the use of rolled siliceous aggregates prevents the material from taking up water after drying.
  • the material also includes a water repellent or waterproofing agent. A water-retaining adjuvant is added to the mixture to allow passage through the machine and provide manageability (ease of operation) to the coating.
  • the material used further comprises a light, fine and spherical mineral filler.
  • This spherical mineral filler promotes vapor transfer, reduces stickiness and provides flexibility for application. Its density is between 0.1 and 0.3.
  • the material also includes an air entrainer for lubricating and facilitating the passage of material in the spraying machine while improving its gel strength. This air entrainer is, for example, a surfactant.
  • the material finally comprises a determined quantity of mica.
  • the size of the mica particles is less than two millimeters.
  • the mica is intended to reduce the stickiness and increase the brightness of the coating once laid.
  • the material may also include organic or inorganic pigments.
  • Additives can also be added according to the specific needs of the users (accelerators, retarders, .).
  • the material according to the invention is moldable for about an hour until two hours after its application. This time is a function of the climatic conditions.
  • the material according to the invention has a good strength in thickness to prevent creep or bead formation at, for example, joints between the blocks.
  • the method according to the invention has many advantages over the prior art. It makes it possible to quickly obtain a surface with clean and regular decorative patterns using little material.
  • the dies are simple to make and are reusable. The process requires no resumption, the realization of the patterns is performed quickly on the fresh coating after laying the plaster layer. It is easy and quick to implement, thanks to the lightness of the dies.
  • embossing stamping it is not necessary to work with several matrix, the matrix being removed immediately after pressing.
  • embossed embossing an operator can apply the dies to a coated surface area while another operator is coating another area. When the stamping of a zone is completed, the matrix can be reused for another area of surface just to be coated.
  • the stamping can also be performed directly on the fresh coating layer, the matrix then being held in position on the coating layer.
  • the patterns can be made on the whole of a surface or on a part only to form a frieze for example. Several dies with different patterns can be used in combination for the same surface.
  • the use of the process according to the invention makes it possible to obtain a velvety coating surface.
  • the appearance of the surface obtained is less porous than that of the prior art obtained by scraping, which reduces fouling, soiling and facilitates cleaning. This also reduces the dust after drying the plaster and thus allows indoor uses.
