Abstract

PURPOSE:To improve external appearance by applying coating material containing aggregate on the sealer treated wall backing face to form an uneven pattern, and applying finish-coating thereto by using top coat material in which colored lightweight aggregate formed of fine hollow bodies are dispersed. CONSTITUTION:A sealer such as acrylic emulsion is applied to the wall backing face 1 of concrete or the like and dried. Coating material 3 containing aggregate formed by mixing quartz sand in acrylic emulsion, for instance, is then applied thereon to form an uneven pattern. Colored lightweight aggregate 4 is formed by covering micro hollow spherical bodies, formed of polysilicate inorganic material or the like, with a paint composition intermixed with colorant. Top material 5 with aggregate 4 dispersed in the acrylic emulsion or the like is applied onto the uneven pattern of the coating material 3 for finish coating. The unique coated wall surface with excellent design effect can be thereby formed, and a stipple feeling can be made distinct. The surface is smooth, and dust hardly adheres thereto, so that dust can be easily removed.

2. Description of the Related Art Due to the westernization of architecture, water-based resins such as acrylic resin emulsions, body pigments such as titanium white and calcium carbonate, and aggregates such as cold water stones are sprayed, rolled, and ironed on the wall surface. There is a construction method that finishes unevenness.

[0003]

In the conventional wall surface finishing method as described above, the hue of the wall surface after the construction is limited because of the single color based on white. Further, when the coating material mixed with the aggregate was applied in an uneven shape, dust was likely to adhere to the rough surface and it was difficult to remove the dust.

The object of the present invention is that the finished hue of the wall surface after construction is deep dot painting, has a light and shade in the dot painting finish, and dust is not easily attached even on uneven surfaces, and dust is easy to remove. It is to provide a construction method for a stippled wall.
