Method of applying clear coating and lamination structure of the clear layer

Abstract

To provide a coating method for clear paint which can make a film thickness of a coated film formed from intermediate coating clear paint comparatively thicker to make a base material have waterproofness and crack followability, and can adjust glaze and gloss of a finished surface with finishing clear paint, so that design of the base material is hardly impaired.SOLUTION: In a clear coating method that coats a base material with intermediate coating clear paint and then coats the base material with finishing clear paint, a contrast ratio of a coated film formed from the intermediate coating clear paint and a contrast ratio of a coated film formed from the finishing clear paint are low and a difference between the contrast ratios is small, which can make a film thickness of the coated film formed from the intermediate coating clear paint comparatively thick so that the base material can have waterproofness and crack followability. As glaze and gloss of a finished surface can be adjusted by coating of the finishing clear paint, design of the base material is hardly impaired.SELECTED DRAWING: None
