料を使用した場合に起こりやすい。[Background Art] As shown in FIG. 2, the inorganic decorative board A' is also coated on the back side of the inorganic board 1 to form a back coating film 5 in order to prevent warping during the painting process and after makeup. is common. This is because if there is no paint film on the back side of the inorganic board 1, only the back side will dehydrate when the paint dries during the painting process, causing uneven moisture content in the inorganic board 1, causing warpage during the process, and Although water absorption and dehydration do not easily occur on the front surface due to the surface coating film 3, water absorption and dehydration occur from the back surface, resulting in warping. As for the painting method, first paint the back side to a thickness of 40 to 100μ.
A back coating film 5 is formed, and then two to three layers of coating are applied to the front side to form a front coating film 3. However, according to this conventional method, the third
As shown in Figures 4 and 4, when the front side is painted after forming the back side coating 5, the air accumulated in the pores in the inorganic board 1 expands during drying, causing the front side coating 3 to foam 6.
There was a problem in that the bubbles formed, or the bubbles were broken, leaving craters 7 on the surface coating film 3. This foaming 6 is likely to occur when a paint with high thixotropy and high viscosity is used, and bubble breakage and formation of craters 7 is likely to occur when a paint with low thixotropy and low viscosity is used.

である。[Disclosure of the Invention] The inorganic board coating method of the present invention involves applying a first layer of coating to the back side of the inorganic board 1 to form a first back coating film 2, and then applying a plurality of layers to the front side of the inorganic board 1. It is characterized by applying a coating to form a surface coating film 3, and then applying a second layer of coating to the back side of the inorganic board 1 to form a second back coating film 4. With this configuration, The above objectives were achieved. That is, the first back coating film 2 can prevent warping during coating drying and also prevent foaming during surface coating, and the second
The back coating film 4 can prevent warping after makeup is applied.

する。 First, a first layer of coating is applied to the back side of this inorganic board 1 to form a first back coating film 2. The thickness of the first back coating film 2 is designed to prevent the coating from warping when it dries, and also to prevent the surface coating from foaming or foaming due to the air accumulated in the pores in the inorganic board 1 expanding when it dries. It is sufficient that the thickness does not cause bubbles to break and leave craters on the surface coating, for example, 20 to 30μ. Next, a plurality of layers, usually two to three layers, are applied to the surface side of the inorganic board 1 to form a surface coating film 3. The thickness of this surface coating film 3 is, for example, 30 to 100 μ. In this case, the reason why you do not paint the back side after painting the front side is because if you do so, the thickness of the front coating film 3 will be large, so the warpage will become large when painting the front side, and the warp will not return even if you apply the back side painting. be. Thereafter, a second layer of coating is applied to the back side of the inorganic board 1 to form a second back coating film 4. The thickness of this second back coating film 4 is
The thickness is such that warpage does not occur after makeup is applied due to lack of balance with the thickness of the surface coating film 3, and is, for example, about 10 to 70μ. Inorganic decorative board A produced in this way
is put to practical use, for example, as a wall material for bathroom units.

A film is formed, and then a second layer of paint is applied to the back side of the inorganic board to form a second back paint film, so the first back paint film prevents warping when the paint dries, and also prevents warping during surface painting. Foaming can be prevented, and the second back coating film can prevent warping after makeup is applied.
