じていた。BACKGROUND ART Conventionally, painting of building materials such as lightweight cellular concrete panels is usually
The same paint is applied twice. However, in the conventional coating method, when a paint having a high resin concentration is applied twice in order to improve the waterproof performance, the impregnation property of the paint into the building material is deteriorated, and the paint swells at a high temperature such as summer. As a result, the paint was peeled off from the building material.

提供することを目的とする。On the other hand, when a coating material having a low resin concentration (high solvent concentration) is applied twice in order to improve the impregnation property, the coating material can be prevented from peeling off, but on the contrary, the waterproof performance is deteriorated. Therefore, an object of the present invention is to provide a method for coating a building material, in which good impregnation properties of the paint and high waterproof performance are obtained together.

する。A method for coating a building material according to a first aspect of the present invention is a method for coating a building material, in which a first coating and a second coating are performed. It is characterized in that the solvent concentration of the paint used in the first coating is made higher than the solvent concentration of the paint used in the second coating.

態が得られる。The building material is a concrete building material such as a lightweight cellular concrete panel. The higher the solvent concentration of the paint, the better the impregnation of the paint into the building material. Therefore, in the first coating, the solvent concentration of the coating is made higher than the solvent concentration of the coating used in the second coating, whereby a coating state in which the coating is well impregnated in the building material can be obtained.

法は、前記溶剤の含量のみを調整して溶剤濃度の相対的
な高低を作ることを特徴とする。Next, in the second coating, by applying a paint having a low solvent concentration (high paint resin concentration),
Although it is not impregnated to the deep part, a coated surface with good waterproof performance can be obtained. Therefore, by performing the coating twice with the solvent concentration of the paint as the above condition, it is possible to obtain a building material in which the paint is well impregnated in the building material and which has high waterproof performance. The method for coating a building material according to a second aspect of the present invention is characterized in that only the content of the solvent is adjusted to make the solvent concentration relatively high or low.

It is convenient to adjust only the content of the solvent while keeping the content of the other components constant. In the method for coating a building material according to the third aspect of the present invention, when the main component in the coating material is 100 parts by weight, the content A of the solvent in the coating material used in the first coating is 60 parts by weight ≦ A ≦ 80 parts by weight, and the content B of the solvent in the paint used in the second coating is 35 parts by weight ≦ B <60 parts by weight. Specifically, it is preferable to set the solvent concentration within the above range.

しいことがわかる。From Table 1, according to the coating method of this embodiment, the solvent concentration of the paint used in the first coating is higher than the solvent concentration of the paint used in the second coating. It can be seen that the painted test building material shows no swelling during forced drying and has low water permeability.
Therefore, the coating method of the present invention provides both good impregnation of paint and high waterproof performance. Then, the mixing ratio of the main agent and the solvent in the paint used in the first and second coatings is such that when the main agent is 100 parts by weight, the content A of the solvent in the paint used in the first coating is 60 parts by weight ≦ A ≦ 80
It can be seen that it is preferable that the content B is 35 parts by weight and the content B of the solvent in the paint used in the second coating is 35 parts by weight ≦ B <60 parts by weight.

生したり、透水性が不良であることがわかる。On the other hand, according to the coating methods of Comparative Examples 3, 4, and 6, the solvent concentration of the paint used in the first coating is the same as the solvent concentration of the paint used in the second coating. It can be seen that the painted test building material has swelling during forced drying and poor water permeability. In addition, according to the coating methods of Comparative Examples 1, 2, and 5, the solvent concentration of the paint used in the first coating or the solvent concentration of the paint used in the second coating is within the solvent concentration range of the above-described examples. Since it is out of the range, it can be seen that swelling occurs at the time of forced drying and the water permeability is poor as in the comparative example.
