Description

DETAILED DESCRIPTION OF THE INVENTION The present invention applies geometric decorative joint patterns such as brick-like, ceramic tile-like, stone-covered, mosaic-like patterns to walls, floors, ceilings, etc. of buildings using specific joint patterns. The present invention relates to a method for easily forming the image using a forming material and a coating material.

Traditionally, building decorative finishing methods such as brick laying and ceramic tiling have been used to apply fired products such as factory-produced bricks, ceramic tiles, and mosaic tiles, or processed and cut natural stones and artificial stones to the walls of buildings. It is applied to floors, ceilings, etc. using the so-called plastering method or tile method, in which one piece or a plurality of pieces are pasted and finished, and a decorative joint pattern is formed as a result. However, traditional construction methods require huge amounts of cost and construction time, so today, wall coating materials and floor coating materials are used to achieve a seamless finish by applying relatively thick coating materials.
Paint materials (hereinafter referred to as decorative paint materials) are increasingly being used. Decorative methods using such decorative coating materials are effective in reducing costs and construction time, but the finished product tends to be flat and monotonous.

However, today, coating materials (including spray materials and paints) that can be applied relatively thickly using equipment such as spray guns, spatulas, and trowels are now available.
In recent years, there have been growing calls for construction methods that use brickwork to create geometric decorative joint patterns such as brick, tile, and stone-like joints on walls, floors, etc. Specific examples of these conventional construction methods are as follows.

(A) Method using masking tape CB) Method using removable paper template with adhesive applied to the back side of die-cut paper (C) Method using low-foaming organic foam instead of the paper in (B) above CD ) A method of using a sturdy reusable formwork instead of paper in CB) above.

According to these methods (A) to (D), tape or "mold"
The paper, foam, and frames (hereinafter referred to as templates) used in this process are temporarily held on walls, floors, etc. using something like a removable adhesive before applying the coating material. , the coating had to be removed as quickly as possible after it was applied. Therefore, it is difficult to adjust the time between the drying of the coating material and the removal of the mold material, which means that if the coating material dries, it cannot be removed ([A]
~ [D]). In addition, (2) the cross section of the paint film after removal of the interlayer material is likely to be distorted ([A] to [C]); Moreover, it is also difficult to dispose of waste materials and flap materials ([A] to [C]). Furthermore,
In the case of CD), it takes time to reuse the molding material, so even if it can be used on a large area at once for walls, in the case of floors, the molding material must be removed while the coating material is still drying. However, this is not possible because it has to be done.The present invention significantly improves the above-mentioned drawbacks. That is, the present invention provides a flexible material that has a releasable paper strip on its surface and an adhesive or pressure-sensitive adhesive layer on the back surface of the construction surface, such as the wall, floor, or ceiling surface of a building, to which an undercoat material has been applied. A decorative joint material made of organic foam is applied to the construction surface, then a thick coating material is applied to the entire construction surface, and while the coating material is still wet, peelable paper pieces of the decorative joint material are peeled off, After that, a top coating material containing a solvent is applied, and by using this method, it is easier to adjust the time between drying the coating material and removing the mold material, and the lumber is sawn. The cross section of the paint film after removal is orderly, and the mold material dissolves to form a part of the 24 layers of the top coat material, so there is no need to treat the mold material, and it is also possible to treat the projecting corners and large corners of the building. It is easy to use, and can be used not only on walls and ceilings.
Even on the floor, it can be done without dragons. Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 1 shows a cross-sectional view of a decorative joint material used in the present invention, and FIG. 2 is a plan view thereof, illustrating a ceramic tile style as one type of decorative joint pattern. In FIG. 1, natural rubber foam, SBR latex foam, and vinyl chloride resin are attached as the soft organic foams, and adhesive or adhesive N (C) is attached to the lower part (back side) of the neck.

The decorative joint material body (a) is the above 3I! It uses one type of foam, which differs slightly depending on the manufacturing method, but it shrinks and dissolves in a general solvent with the components used in the solvent in the paint. Its volume is small and it has the property of forming a film after the solvent evaporates. In addition, the thickness of the decorative joint material body <a> shall be 0.5 mm or more, and although there is no particular restriction on the thickness, it should be approximately 10 nm +++ or less, and 0.5 mm
If it is less than m, the shadow between the joint and the paint film tends to be less noticeable. Heat theory, coloring of decorative joint materials can be done at any time. Next, as for the removable paper strip (b), although the material is not particularly specified, water-resistant sheets such as synthetic resin sheets are used in order to keep the marks on the surface of the decorative joint material made by the subsequent thick coating material orderly and to prevent shrinkage. A material with good water resistance is desirable. It is preferable that a release paper strip (d) is attached to the surface layer of the adhesive or pressure-sensitive adhesive layer (c) in advance in order to transport the decorative joint material.

Figures 3 to 7 show the construction method according to the construction procedure, and Figure 3 shows an arbitrary I!
The neck undercoat material (f) is applied, and the undercoat material (f)
This shows the state in which the decorative joint material has been applied to the dry, hardened surface.

The undercoating material is preferably one that has good mutual adhesion with the adhesive or pressure-sensitive adhesive layer applied to the back surface of the decorative joint material, which requires normal coating performance. FIG. 4 shows a state in which the thick coating material (g) has been applied to the entire construction surface. The material of the thick coating material (g) is not a coating material containing a solvent, but rather cement or synthetic polymer water to ensure resistance to the solvent components of the top coating material of the decorative joint material body (a). A dispersion liquid (synthetic resin emulsion or synthetic rubber latex) or a non-aqueous dispersion is used as the vehicle. Next, FIG. 5 shows a state in which the thick coating material (g) has been removed from the releasable paper pieces (b) of the decorative joint material in an undry state.

Thereafter, the thick material coating material (g) is dried for a sufficient period of time while leaving the decorative joint material main body (a) and the thick material coating material (g). Figure 6 shows the state in which after the dry explosion of the thick coating material, the top 'a material (h) containing an organic solvent is applied to the entire construction surface, and by applying this top coating material (h), As shown in Fig. 7, the decorative joint material main body (a) shrinks and dissolves, and as time passes, it is surrounded by the topcoat material (h), and the topcoat material is removed together with the adhesive or pressure-sensitive adhesive layer (c). The main dry bomb mwA(i) is formed.

In this way, a tile-like decorative joint pattern is formed. In addition, in Fig. 3, the decorative joint material main body (a
) is difficult to attach to curved parts, protruding corners, and large corners of buildings with non-soft organic foam bottle stands, and many of them are difficult to dissolve in solvents. The present invention is not limited to the geometric pattern of thermal tiles, but can create any pattern such as brick, stone, mosaic, or block stone depending on the processing form of the decorative joint material. .

With this decorative joint pattern forming method, as mentioned above, it is easy to adjust the time between drying the coating material and removing the molding material, so it can be used on walls, floors, ceilings, and even on roads, pools, etc. Also, since the cross-section of the paint film after the removal of the molding material becomes orderly, it is no longer considered to be a low-grade product, such as imitation tiles, and has a high-class image. Moreover, since the mold material itself constitutes a part of the coating film formed at the joint, there is no need to discard it, and the performance of the coating film can be improved.
