Abstract

<P>PROBLEM TO BE SOLVED: To provide a construction method for painting and forming a fair-faced concrete pattern, a ceramic tile pattern, and a brick pattern on a concrete surface and interior and exterior board surfaces easily in a short period of time and decorating an elegant multicolor pattern by a stately and natural tone of color. <P>SOLUTION: In this construction method, various emulsion paints, NAD type paint, and solvent type paint having the color being softer than that of a substrate having degree of viscosity used usually are first painted by using a roller for painting. While the paint is not dried, a multicolor spotted pattern is formed and painted by using the same kind of viscous paint having the color being darker than that of substrate color and using a recessed and projected three-dimensional synthetic sponge or a roller type synthetic sponge, and an undercoat paint is repeatedly painted by using the roller for painting. Since the pattern is formed while the paint is not dried, a term of construction work can be greatly shortened. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention provides a painting method for decorating locally on the concrete surface and the interior / exterior board surface by using the natural pattern of the concrete and the elegant and deep porcelain tile pattern and brick pattern as a design.

  Patterns that appear in the concrete finish of the building are concrete mix, placement time, time, concrete placement and process, concrete curing period, water containing pigments in the formwork, or concrete Due to the fabric repair method, the same concrete pattern does not appear as a single concrete pattern. Due to the above-mentioned conditions, the exposed concrete finish has a rough mottled pattern, and its natural, high-design color tone gives the building a profound sense of value and presence, and has been widely used in general.

  However, defects, discoloration or deterioration due to aging, or weathering contamination appearing on a part of the concrete base impairs the rough mottled pattern. In addition, the exposed concrete finish contains components of inorganic substances such as concrete cement and lime, so it is vulnerable to acid rain and ultraviolet rays, and is easily affected by it, so the decorative pattern is lost.

  In order to regenerate this hindered or lost state, it has so far been subjected to repair coloring with a blended polymer cement mortar that has been toned with pigments and dyes, and then applied with a clear water repellent or applied to a concrete substrate. Apply permeable waterproofing to the entire surface of the concrete with a cement mortar, paint it, paint it with a clear paint such as fluororesin or silicone resin, which has high durability and weather resistance after complete drying. A method of coloring and concealing the surface is adopted.

  However, the repaired traces of the substrate were not compatible with the concrete base, and the paint coloring traces were too emphasized.

Also, in the past, when repainting the outer wall, it takes time and time to express a variety of patterns with multiple colors, so a method of painting by painting the entire wall with a single color is often used.

  However, since a method using a mortar system uses a wet material, it is difficult to distinguish the color tone after drying, and a high level of technology is required for the color matching. In the repair coloring method, the pattern is applied to the dried base color, and then the clear paint is applied after drying. However, since the waterproof protection function for durability and weather resistance is required, the color unevenness of the coating film and the pattern color In order to amplify the light and shade situation, a discoloration with the surrounding concrete finish color will occur and the pattern color will be revealed.

Further, since a drying period is provided for each painting process, there is a problem that a lot of time and days are required for finishing the finish painting.
The present invention has been made to solve such problems, and an object of the present invention is to provide a method for forming a natural, heavy, and beautiful exposed concrete pattern, a porcelain tile pattern, and a brick pattern.

  The present invention is a conventionally known method, such as cement mortar or blended polymer cement mortar, after repairing the cracked part of the exposed concrete, the junker and the cold joint, etc., and scraping and flattening the concrete surface with a trowel etc. Dry thoroughly and apply architectural sealer or primer.

  After applying the sealer or primer, apply the primer. As the paint used for the undercoating, various emulsion-based paints having a viscosity which is usually used and which is not excessively diluted are suitable. A paint that has been adjusted to the approximate color of the existing concrete color with the above-mentioned appropriate type of paint, is primed on the entire surface of the concrete with a brush roller for painting, and a pattern that is usually darker than the undercoat paint on the painted surface that has not yet dried. After coating the coating material with a cubic synthetic sponge with unevenness, or by applying a pattern so that it partially rolls with a synthetic sponge roller with unevenness, it is used for undercoating before it is still dry. Apply a thin coat of paint and top coat. After the coating so far is completely dry, a matte clear paint is applied to improve weather resistance and waterproof resistance.

  In addition, the entire surface including the tile joints of the exterior material that forms the porcelain tile pattern is primed with a painting roller, and a paint for a pattern that is darker than the undercoating paint is applied to the painted surface that has not yet dried. Pattern with a synthetic sponge. At this point, several different colors can be applied simultaneously. After the pattern coating is applied, the top coat is thinly layered before it is dried. After the process is dried, the clear coating is applied.

  The patterning paint is located in the intermediate layer between the base coat and the top coat that have not yet dried, and the paint is a normally used viscous paint that does not dilute too much. By presenting the toning state, it is possible to form extremely natural, heavy, and beautiful concrete patterns, porcelain tile patterns, and brick patterns without emphasizing the outline of the rough mottled pattern that is a patterning paint. And can be decorated with excellent design. Moreover, since the work is carried out before each coating process is still dry, the construction period can be greatly shortened.

  Hereinafter, an embodiment of a paint forming method for decorating the exposed concrete pattern of the present invention will be described. The foundation repairs such as chipping of concrete frames, junkers and cold joints, and the foundation treatment for fouling, secular change, and discoloration are well-known and conventional techniques, and embodiments of the present invention will be described in the following steps.

  After finishing and repairing the groundwork and thoroughly drying it, brushes, rollers, and airless primer for construction sealer and wet color prevention to strengthen adhesion to concrete groundwork and to prevent whiteness Apply to the entire surface to be treated by spraying and dry. After confirming dry touch, apply the primer.

As the undercoat paint, a colored paint material, which is an intermediate paint material used for the appropriate various paints, is used. The undercoat paint color is adjusted to a lighter gray system than the standard concrete color, but local re-coloring is desirable in order to approximate the most concrete color of the existing concrete color.

  Undercoating paints not only conceal the hindrance of concrete, but also provide concrete protection with a waterproof function, and at the same time have a great advantage especially in coloring near the concrete base color. In addition, this primer is required to be a paint having excellent durability and weather resistance in order not to be contaminated by ultraviolet rays or the external environment. Suitable concrete paints are acrylic resin emulsion paint, urethane resin emulsion paint, silicone resin emulsion paint, fluororesin emulsion paint, non-water emulsion type acrylic resin NAD paint, urethane resin NAD paint, silicone Resin NAD type paint, fluororesin NAD type paint, solvent type acrylic resin paint, urethane resin paint, silicon resin paint, and fluororesin paint are suitable. Also, in the case of ceramic siding that is an exterior material, the same applies to the paint. When the coating material is made of wood, iron, or galvanized steel, an alkyd resin-based paint is suitable in addition to the paint. Acrylic resin emulsion-based paint and synthetic resin emulsion-based paint are suitable for calcium silicate board, wooden plywood, and plasterboard interior materials.

Undercoating is a commonly used viscous coating material, and is applied to the surface to be colored and the entire surface with a paint brush roller so as not to cause color unevenness and color transparency. The used paint brush roller is temporarily placed so that no further undercoat paint material is added. Next, a mottled pattern is applied so that the undercoat is not yet dried.

The forming tool used for the mottled pattern coating as an intermediate coating uses a synthetic sponge with irregularities. The standard coating amount of the paint used for pattern coating is 0.12 to 0.18 (Kg / m ² / time), which is the viscosity normally used for architectural coating. Synthetic sponges are ideal for patterning tools because they can. Coarse patterns, fine patterns, and continuous patterns are applied using two types of forming tools, a cubic synthetic sponge and a cylindrical synthetic sponge. The size of the cubic synthetic sponge is about 15 cm in width, 10 cm in length, and about 5 cm in height, and the size of the cylindrical synthetic sponge is about 7 cm in diameter and about 12 cm in length. The unevenness of the synthetic sponge is not aligned vertically and horizontally, but is processed so as to be arbitrary. Similarly, the uneven synthetic sponge roller uses an uneven mold. The container to be impregnated with the forming tool is a container with a flat bottom so that the paint impregnated into the synthetic sponge can be confirmed at any time.

  Next, the uneven synthetic sponge is impregnated with a mottled pattern paint, which is a gray color darker than the undercoat paint color, and is patterned so as to strike the surface to be colored which has not been dried yet. In addition, with the uneven synthetic sponge roller, the rolling pattern is painted so as to be partially shaded. It is possible to decorate a concrete pattern that is naturally similar by repeating the loading several times so that the pattern does not become monotonous.

  Next, before the patterning paint is still dry, the top coat is applied so that the paint brush roller, which has been used before, is not excessively impregnated with the undercoat paint material, is slowly layered in the same direction. .

In order to further enhance the durability and weather resistance, after the top coat is dried, a matte clear coating is applied to the entire surface layer, and the coated surface is protected with a transparent film. The matte clear paint is used because the surface finish of the exposed concrete finish fades over time, but the painted surface remains glossy and does not match the surroundings, creating a sense of incongruity. . Apply a matte clear paint to eliminate the discomfort.

The above is the paint forming method to decorate the concrete pattern. Similarly, conventionally known surface treatment is applied to exterior siding board, calcium silicate board, interior plaster board board, etc., wood part, iron part, galvanized steel sheet part as well. After the construction, it is possible to decorate several kinds of paints with different colors for patterning, and the paint forming method is a concrete pattern as a design of interior and exterior, and a variety of elegant and deep porcelain tile patterns and bricks The pattern can be applied to form a film.

  Also, the concrete pattern coating formation method omits the undercoating and applies a pattern coating to the dried sealer or primer surface. The same effect can be obtained by the method of construction, but the durability and weather resistance can be expected from the construction method in which the entire surface is undercoated.
