Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To recover a coating film including intermediate coating and top coating by peeling separately from an undercoating film and a primer layer.SOLUTION: A coating film peeling agent for partial peeling where the concentration of a peeling accelerator is two times or more of the concentration of a peeling accelerator contained in a coating film peeling agent for the whole peeling is coated on a coating film so as to have a thickness of the total value or more of at least intermediate coating 20 and top coating 22 and the intermediate coating 20 and the top coating 22 are peeled while remaining undercoating 14, 16, 18 when the film thickness of the whole coating film is a peelable film thickness obtained by one coating of a coating film peeling agent for the whole peeling containing the peeling accelerator, an amide-based compound or an alcohol, a thickener and water.
