FR2783751A1 - Method of making imitation wood trim for wall involves applying paste to wall and contouring it using roller - Google Patents

Abstract

The method of making a simulated wood wall decoration involves placing a fibre filled paste onto the wall surface using a roller. The paste is contoured using a second cylindrical roller with a simulated wood grain in reverse on its surface. A wood colour stain is then applied using a brush, with the surplus removed on a cloth.

Description

The subject of the present invention is a method for producing

  decorative coatings imitating wood as well as the coatings thus obtained. It concerns the industrial and commercial field of the manufacturing and distribution of

  surface coating products intended in particular for the building industry and applicable both to walls or walls, and to decorative panels.

  To date, the different forms of decoration and painting have always consisted of applying several uniform layers of paint with tools such as brushes, knives, rollers, even hands. Decorative effects aimed at imitating natural products such as wood or marble have always been created by the superposition of more or less transparent layers of paint or varnish which let the previously applied colors shine through. We thus obtained multicolored effects and

  in particular aspects reminiscent of wood.

  Recently, there have also been so-called "multicolored" paints which are a heterogeneous mixture of two or three colors on a paint base. This mixture is generally applied by spraying and gives a regular multicolored effect (paint drops of

different colours).

  The invention relates to a new technique which consists in applying a mass of product which when spreading on the support by means of special tools creates a decorative effect in relief and in nuanced shades.

  similar to the veins of natural wood.

  The method consists first of all, using a tool provided with a striated cylindrical face, in relief veins having the appearance of wood on the surface of a fibrous paste extended before the roll on the support. to coat, then apply with a brush a colored topcoat, the excess of which is removed with a glove or a soft cloth so as to create shades of color by eliminating the

  finishing on the projecting parts.

  In the accompanying drawings, given by way of nonlimiting example of one of the embodiments of the subject of the invention: FIGS. 1 and 2 respectively show from the front and from the side the making of the veins in the extended fibrous dough on the support, figure 3 shows the passage of the colored finish on the fibrous paste and figure 4 represents the elimination

  excess colored finish using a glove.

  The realization of a coating according to the invention is carried out by firstly rolling with a roller, on a healthy and clean support, a layer of fibrous pulp 1 with a thickness close to 0.5 mm, after

  possible passage of a universal fixer of known type.

  A layer of wood is then given to the layer of fibrous pulp which is still fresh by means of a special tool 2 comprising a striated cylindrical face, working from top to bottom, strip after strip, making them overlap slightly while printing with tool 2 oscillations around a horizontal axis (arrows 3, figure 2) to vary its inclination

  so as to produce irregular veins 4.

  After drying for 24 hours, a colored topcoat is applied using a brush 5 passed in the direction of the veins, then a glove is passed over the surface of the coating to remove the colored finish on the protruding parts so as to obtain variations in color bringing out

the "wood" patterns.

  The fibrous pulp 1 consists of a product formed by the mixture of a water-soluble adhesive binder

and colored fibers.

  The paste and the colored finish are of different but similar colors and are supplied ready to use, which allows easy use of the product.

  by both an amateur and a professional.

  The coatings obtained by this process are very resistant and have great originality due to their raised surface. Their appearance can be extremely varied by varying the colors of the fibrous pulp 1 and of the colored finish and by playing

  on the inclinations of the special tool 2.

  For example, it is possible to obtain an effect of slats by delimiting them beforehand by means of masking adhesive before applying the fibrous paste 1 to the roller and achieving the "wood" effects, the adhesive being removed after drying and finishing

colored applied.

  The positioning of the various constituent elements gives the object of the invention a maximum of useful effects which had not, to date, been obtained.

by similar methods.

Claims (4)

  1 '. Method for producing decorative coatings   imitating wood, intended in particular for the building sector and suitable for   foldable on both walls and walls as well as on decorative panels, characterized in that a layer of fibrous paste (1) is firstly rolled onto the support to be coated, which is then produced at the surface of said fibrous pulp still fresh, by means of a special tool (2) provided with a ridged cylindrical face,   veins (4) in relief having the appearance of natural wood, which we call   then apply with a brush passed in the direction of the veins (4), after 24 hours of drying, a colored top coat including. the surplus is removed with a glove (6) or a soft cloth so as to   eliminate said colored finish on the projecting parts.   2 '. Method according to claim 1, characterized in that the special tool (2) is provided with a ridged cylindrical face.   3 '. Method according to any of the claims   above, characterized by the fact that the wood appearance is obtained by working from top to bottom with the special tool (2), strip after strip, making them overlap slightly while imparting to said special tool oscillations around a horizontal axis to make   vary its inclination so as to produce irregular veins (4) lières.   4 '. Method according to any of the claims   above, characterized in that the fibrous pulp (1) and   the colored finish are of different but similar colors. - 6 -   '. Method according to any one of the preceding claims, characterized in that the fibrous pulp (1) is   consisting of a product formed by the mixture of a water-soluble adhesive binder and colored fibers.   6 '. Decorative coating imitating wood, intended in particular for the building sector and applicable both on walls and walls as on decorative panels, 10 characterized in that it consists of a layer of fibrous paste (1) comprising veins (4) in relief having the appearance of natural wood, this fibrous layer having received a colored finishing layer of different shade but close to that of the fibrous paste layer (1), said colored finish being on the 15 protruding parts having been removed so as to obtain variations   of color bringing out the "wood" patterns.
