A Literature Survey on the Vapor Permeability of Coating Materials for textured Finishes of Buildings

Abstract

According to past studies,it is considered that the vapor permeability of coating materials is related to durability of RC components.However,it is pointed out that the grade og vapor permeability is easy to change by material amout,painting condition ,test method and so on.So,it is difficult to know the general value of vapor permeability each the material categorized in JIS.In this paper,it makes clear the range of the vapor permeability in past studies by literature survey.Also,it makes sure the validity of the suvey's results by a vapor test.
