Cleaning step (S10) to clean the plate glass surface using a urethane thinner to remove foreign matter on the plate glass surface. If there is foreign matter on the surface of the plate glass, the pearl mixture paint is not applied well in the subsequent application step (S30), and thus the desired cloud pattern is not formed on the glass surface.

In the mixing step (S20), a curing agent and a thinner are blended into a transparent mixture and a pearl mixture paint in which pearls having a size of ultrafine particles having a size of 1 nm to 100 nm are mixed. When mixing the pearl mix paint, stir well to prevent the pearl particles from sinking into the paint. If it does not stir well and the pearl particles sink into the paint, the sunk pearl particles will not contribute to the pattern formation. Pearl particles must be evenly mixed with the paint to form a cloud-shaped pattern all over the glass surface. In addition, when the size of the pearl particles is larger than 100 nm, the weight of the pearl particles is heavy in the pattern forming step (S40), so that the surface tension does not occur between the paint and the glass surface, and even if the surface tension occurs, the flow of the pearl particles does not occur at all. The pattern is not formed.

It is preferable to mix | blend the weight ratio of a pearl mix paint, a hardening | curing agent, and a thinner in the compounding ratio of 4-6: 1: 1-2, and it is used as a diluent for diluting an exciting pearl mix paint.

In the application step (S30), using a spray of air is applied to the surface of the plate glass washed in the cleaning step (S10) a pearl mixture paint blended with a curing agent and thinner.

In the pattern forming step (S40), when the pearl mixed paint is applied to the surface of the plate glass in the applying step (S30), the surface tension is generated between the paint and the glass surface while the pearl particles mixed in the paint flow, thereby forming a cloud-shaped pattern on the glass surface. Then, the pearl mixed paint having a cloud pattern is cured by the curing agent. As described above, when the pearl particles are heavy, the pearl particles do not flow and do not form a cloud pattern. In addition, the pearl particles should be evenly mixed with the paint to form a cloud-shaped pattern uniformly on the entire glass surface, which makes the decoration beautiful.

The first drying step (S50) may dry the plate-shaped plate glass for 1 hour to 3 hours at a temperature of 20 ℃ to 100 ℃ or may be dried in a natural state for more than 8 hours.

Color coating step (S60) is applied to the surface of the glass plate with a color mixing paint compounding the weight ratio of the colored paint, the curing agent and the thinner in a compounding ratio in the ratio of 5: 1: 2-3.

The secondary drying step (S70) is to dry the plate glass coated with the color mixture paint under the same conditions as the primary drying step (S50).
