Description

  The present invention relates to a method for finishing a wall surface of a finishing coating material for buildings using a synthetic resin emulsion as a binder.

  Architectural finishing coating materials using synthetic resin emulsion as a binder can easily form uneven patterns, are easy to handle, have good workability, and can create uneven patterns on the wall surface without requiring special skills. However, there is a limit to the creation of a concavo-convex design with a single color, and there are problems such as lack of shading and the inability to create delicate designs, which often depend on the skills of advanced craftsmen.

  In Patent Document 1, an undercoat film having a convex portion is formed with a colored paint directly or via a primer layer on a substrate surface, and then an undercoat paint with a color tone different from the color tone of the undercoat film is used. After coating so that the color tone of the film is concealed and the shape of the undercoating film can be recognized, the undercoating is rubbed on the convex part of the overcoating film while the overcoating film is in a fluid state. A method for forming a multicolored pattern coating film characterized by the color tone of the convex part of the coating film has been proposed, and a method for solving the problem that the multicolored pattern coating film is uniform, flat and poorly changed is disclosed. ing.

  Patent Document 2 discloses that in a design property imparting method including a step of applying a design paint to a wall surface provided with unevenness and a step of scraping off with a rubber scissor, the concealment ratio of the 0.125 mm film thickness of the design paint is 0.

JP 2002-320913 A JP 2007-175580 A JP 2007-262294 A JP 2004-211035 A JP 2010-248304 A

  However, in the inventions described in Patent Document 1 to Patent Document 5, whether or not the unevenness and the expression of the pattern in the actual construction are largely dependent on the sense and skill of the construction craftsmen, There is a problem that the range of expression is within a certain limited range.

  The problem to be solved by the present invention is that the three-dimensional pattern of the wall surface can be used even if it is not a skilled construction craftsman who is familiar with the construction equipment used in the construction of coating materials such as scissors and roller brushes. It is to provide a wall finishing method in which the three-dimensional pattern obtained by the shaping roller can be made to have a real feel and be calm, with the same texture, concave and convex portions having different tones, .

  In the first aspect of the present invention, a synthetic resin emulsion-based finishing coating material is applied to the base, and is molded with a roller having an uneven shape of 0.5 mm or more and 6.5 mm or less, and the color tone after drying is Provided a wall finishing method characterized by applying different sand wall paints with a wool roller with a fiber length of 15 mm or less, and provided a solid feel to the three-dimensional pattern given by the shaping roller. It can be.

  The wall surface finishing method according to the present invention has the effect that the texture is the same between the concave portion and the convex portion, and the color tone is different.

In addition, unevenness is imparted by rolling a roller that has been provided with an uneven shape in advance on a coating material that has been applied to a base such as a wall surface. Even those who do not have the effect of easily imparting irregularities having high design properties to the coating material.

It is a substitute photograph of the shaping roller (width direction 23 cm, roll diameter 6 cm) used in Example 1. It is a substitute photograph of the shaping roller (size is the same as FIG. 1) used in Example 2. It is a substitute photograph of the shaping roller (size is the same as FIG. 1) used in Example 3. 2 is a substitute photograph of the finished state of Example 1 (size 45 cm × 60 cm). 6 is a substitute photograph of the finished state of Example 2 (size 45 cm × 60 cm). 6 is a substitute photograph of the finished state of Example 3 (size: 45 cm × 60 cm).

  In general, architectural finishing coating materials can easily obtain a three-dimensional pattern. However, it is difficult to impart a new design with this three-dimensional pattern alone, and even if a paint having a different color tone is applied to the convex surface of the obtained three-dimensional pattern, the three-dimensional pattern is not uniform on the entire wall, and the balance is Missing design grant. The cause of this is that craftsmanship is required to uniformly apply the three-dimensional pattern. In addition, if the finish finish coating material for construction and the texture of the paint applied to the convex portions are different, a wall having a calm atmosphere cannot be formed. The present invention solves these problems and will be described in detail below.

Synthetic resin emulsion-based architectural finish coating A water-based coating material that uses synthetic resin emulsion as a binder, and can be easily patterned with brushes, scissors, rollers, etc., mainly composed of aggregates, fillers, thickeners, pigments, etc. It is a compounded material that contains 250 to 450% by weight of aggregate and filler with respect to the solid component of the binder. Even after application and drying, the three-dimensional shape is almost maintained without being lost. Is done. The thickener is blended in order to make it suitable for dripping at the time of application, and workability of application tools such as brushes, scissors, and rollers, and the pigment can be colored arbitrarily.

Forming roller A roller that gives a three-dimensional shape to the coated surface after applying the above-mentioned synthetic resin emulsion-based finishing coating material to a substrate such as a base, and transferred from various materials and machined ones. A cylindrical soft roller having a soft elasticity is preferably made of silicon resin for reasons such as easy manufacture. As for the unevenness | corrugation provided, 0.5-6 mm is preferable, the design provision after a finishing cannot be performed if it is less than 0.5 mm, and if it exceeds 6.5 mm, a crack will occur after drying of the synthetic resin emulsion-based coating material. , Variation occurs in the shaping shape of the coating material applied by the roller. The hardness of the forming roller is preferably 20 to 30 according to JIS K7215 Shore A. Within this range, the unevenness of the substrate such as the ground can be absorbed by deformation of the shaping roller, and the durability of the shaping roller can be maintained. In addition, by using a shaping roller, a uniform three-dimensional pattern can be imparted to the entire wall without depending on craftsmanship.

  In the synthetic resin emulsion-based building finishing coating material according to the present invention, an aggregate having an average particle size of 0.3 to 0.9 mm is further blended in an amount of 90 to 150% by weight based on the finishing coating material. The moldability and mold release properties are increased, which is preferable. Aggregates can be made of cinnabar sand, gangue stone, aragonite powder and the like.

In order to improve the transferability of the unevenness to the coating material of the shaping roller with a wool roller having a fiber length of 15 mm or less before giving the unevenness with the shaping roller to the synthetic resin emulsion-based finishing coating material, A transfer liquid is applied to the shaping roller. This transfer solution is compatible with water-based architectural finishing coating materials, and is easy to release from the molding roller, and is further molded when sand wall paint is applied to the molded coating materials described below. JT-180 (Aika Industry Co., Ltd., trade name, silicone-based aqueous solution) is a commercially available product. 70-90 g / m ^{2 is} applied.

Sand wall-like paint The sand wall-like paint used in the present invention is usually applied to the surface of the coating material of the wall to which design properties such as irregularities are imparted by the synthetic resin emulsion-based finish coating material. It is a paint intended to recover the color tone or change the color due to dirt or the like generated by the contamination. Therefore, it is not necessary to provide a large three-dimensional shape as in the case of the synthetic resin emulsion-based finish coating material, and an appearance that is a sand wall-like surface texture can be imparted to the entire unevenness with a wool roller.

In addition, this paint has a synthetic resin emulsion binder of 10 to 20% by weight of the total solid component, an aggregate and a filler of 40 to 60% by weight, titanium oxide for concealment, and a pigment for the colorant. Blended. Here, the aggregates are classified according to the average particle diameter D ₅₀ , those having an average particle diameter of 70 to 500 μm are used as aggregates, and the average particle diameter is less than 70 μm as fillers. In order to stably obtain the sand wall appearance, the aggregate weight / filler weight is preferably 0.1 to 5.0. The synthetic resin emulsion is preferably an acrylic resin in terms of adhesion. These commercially available products include Aikajo Riput Fresh JQ-800 and JQ-810 (above Aika Industry Co., Ltd., trade name).
